Innovative TSHD fitted out with Damen semi-axial dredge pumps
The state-of-the-art 3,200 m3 Trailing Suction Hopper Dredger (TSHD) Charlock has been equipped with two Damen dredge pumps. One highly innovative semi-axial dredge pump is fitted on the trailing pipe, the other dredge pump is mounted inboard. Both dredge pumps work in series, enabling a highly efficient dredging process.
The semi-axial dredge pump is a new addition to the wide Damen dredge pump range. As for all Damen dredge pumps, it has been designed for the harsh dredging environment with special focus on minimising wear and maximising efficiency. The semi-axial dredge pump installed on the Charlock, type OBP9080HA, has various advantages for the owner. Its weight is relatively limited, reducing the required hoisting capacities of the gantries and winches on board. Moreover, the limited cross section minimises the drag forces in the drag arm. Also, the required power is limited; the semi-axial pump is equipped with a 1,200 kW electric motor. Nonetheless, the semi-axial dredge pump delivers some 16,000 m3/h of mixture at 50% concentration and at an excellent efficiency of 85%.
The cast dredge pump wear parts have been designed in close cooperation with the foundry. All cast elements, including the 2-parted pump casing, have been dimensioned optimising the foundry process boosting the casting accuracy and reducing the risk on mis-casts. Hence, the quality of the cast parts is improved. The various wear parts can be cast in different materials depending on the material to be dredged.
The semi-axial dredge pump will work in series with the Damen inboard dredge pump, type BP8065MD. The low pressure semi-axial dredge pump delivers the dredged mixture with minimal head at the inboard dredge pump. This single-walled centrifugal dredge pump either delivers the mixture to the hopper during loading, but it can also pump ashore using the bow coupling unit or rainbow. The inboard BP8065MD dredge pump is driven by a 3,200 kW electric motor.
Damen is pleased to have taken part in the design and delivery of a TSHD as innovative as the Charlock.


The 12th Five-Year Plan for Renewable Energy, which will be published soon, aims for eight 10-gigawatt hydropower bases by 2015, which surpasses market estimates for six, according to Industrial Info Resources:
As reported, more than 60 large-scale hydropower stations will kick off construction on the previously planned six 10-GW hydropower bases, namely along the Jinsha River, Yalong River, Dadu River, Lancang River, Nujiang River, the Yellow River, the Brahmaputra River and others.
More than 13 key hydropower stations, such as the Baihetan, Longpan and Wudongde hydropower projects will kick off construction on the Jinsha River; several key hydropower projects such as the Nuozadu, Dahuaqiao and Kagong projects will begin construction on the Lancang River. More than 40 key hydropower stations will be built on either river valleys.
It's expected that the newly commissioned capacity of hydropower during the Twelfth Five-Year Plan will reach about 87.5 GW. About 52 GW of installed capacity will begin operation in the six large-scale hydropower bases, while the remaining 35.5 GW will be in other areas. By the end of 2015, the total installed capacity of conventional hydropower in China will reach about 284 GW, accounting for about 71% of the total exploitable capacity.
While China goes full steam ahead with hydro, it is rumored to be canceling its push to put 20 million electric cars on the road by 2020.

Up Flow Filter: Removes fine TSS, metals, nutrients and bacteria with an advanced sorptive media filtration bed.
Passive Self-Cleaning: Up Flow Filter is passively back washed with drain down filters.
Once flow into the system subsides, the water level in the system will start to fall. Once the water level reaches the upper effluent side of the up flow filter it can no longer discharge. The remaining water within the filtration media is forced downward as the drain down filters continue to treat and discharge stormwater. This passive back wash action releases pollutants that would otherwise contribute to long-term clogging and performance issues.

We practice the design of mining systems of pump dredges, the development of design documentation, as well as the production of tools and equipment for dredge heads, which, depending on the mining conditions and the physical and mechanical characteristics of the extracted soil, can be equipped with jet pumps (ejectors), jet and other types of disintegrators. When designing dredge heads, we take into account the specific factors of the formation of erosion and suction flows in the underwater face. As a result of the head-capacity curve construction, we carry out the justification and selection of dredge and water pumps, pulp pipelines and water pipes, stop valves and testing instruments.
Our qualification in this area of activity is based on the completed dissertation researches, monographs, books, engineering calculation methods, scientific articles, as well as on many years of experience in the design of pump dredges and the presence of machines introduced into production.

The San Diego County Water Authority has released a time-lapse video showing progress of the San Vicente Dam Raise Project that began in 2009, and is scheduled to be completed late 2014 or early 2015. The reopening of the lake for fishing will depend on the amount of rainfall the area receives after completion. The lake will reopen when the water level reaches the new launch ramp and marina.
The project will increase San Vicente’s water storage capacity from its previous 90,000 acre-feet capacity to 242,000 acre-feet by raising the existing dam from 220 feet to 337 feet. The increase in storage capacity will result in 500 more surface acres of lake, from its original 1,069 surface acres to 1,500.

Main Article Content
The Research studies on filtration shows, over 70 Percentage of hydraulic systems failures are due to contamination or poor liquid conditions. Therefore filters are necessary in modern hydraulic systems to provide specified level of cleanliness, reliability, the hydraulic efficiency and the performance of the filters needs to be ensured the real life working conditions. For efficient operation of any pumping system, appropriate selection of associated pump is highly essential which in turn needs correct estimation of head losses of various elements specials of the pumping system including valves, filters, bends, piping etc. Since electric energy required for pumping reduces with reduction in head loss in pumping system. A need for minimum loss of head across the filters is required in pumping systems. On this background the selection of filter for a certain application is often based not solely on the filtration efficiency and dirt capacity but also low head across the filter.
The paper highlights the improvisations effected in design of Y type filter through research undertaken at CWPRS for achieving percentage reduction in head loss with original design by using CFD simulation and experimentation. The reduction in head loss to such an extent had achieved huge saving in recurring expenditure towards power charges for pumping purpose.

The Impact of the Uncertain Input Data of Multi-Purpose Reservoir Volumes under Hydrological Extremes
The topic of uncertainties in water management tasks is a very extensive and highly discussed one. It is generally based on the theory that uncertainties comprise epistemic uncertainty and aleatoric uncertainty. This work deals with the comprehensive determination of the functional water volumes of a reservoir during extreme hydrological events under conditions of aleatoric uncertainty described as input data uncertainties. In this case, the input data uncertainties were constructed using the Monte Carlo method and applied to the data employed in the water management solution of the reservoir: (i) average monthly water inflows, (ii) hydrographs, (iii) bathygraphic curves and (iv) water losses by evaporation and dam seepage. To determine the storage volume of the reservoir, a simulation-optimization model of the reservoir was developed, which uses the balance equation of the reservoir to determine its optimal storage volume. For the second hydrological extreme, a simulation model for the transformation of flood discharges was developed, which works on the principle of the first order of the reservoir differential equation. By linking the two models, it is possible to comprehensively determine the functional volumes of the reservoir in terms of input data uncertainties. The practical application of the models was applied to a case study of the Vír reservoir in the Czech Republic, which fulfils the purpose of water storage and flood protection. The obtained results were analyzed in detail to verify whether the reservoir is sufficiently resistant to current hydrological extremes and also to suggest a redistribution of functional volumes of the reservoir under conditions of measurement uncertainty.

Improved flooded area/power ratio
The River Madeira has a flow of 4,000 m³ per second during the dry period and 45,000 m³ per second in the rainy period. For this reason, the kind of turbine for the operation is the bulb type which is more suitable to the conditions of this river, with large volumes and water speed and reduces the need for large reservoirs. The flooded areas will be practically the same size as those which occur during the annual flooding of the river.
The Santo Antônio HEP has the best ratio between the flooded area and the installed capacity of all the hydroelectric plants in the Amazon plain region. The plant´s reservoir will measure 271 km². When the area of the natural flood is dammed, the area of the reservoir comes to 110 km².

As part of Zimbabwe's preparations to successfully co-host the UNWTO conference, the project is expected to offer long-term value to the Victoria Falls water supply system.
"As council, we discussed the issue of raising water capacity and a new water station was suggested,” said Victoria Falls mayor, Nkosilathi Jiyane.
According to a ZINWA planning manager, the expansion plans will include deepening the existing raw water abstraction channel in the banks of the Zambezi River.
Plans will also be underway for the construction of a new pump station at the Zambezi and booster pump-stations, while the pumping capacity will be upgraded from the current 900 cu/m per hour to 1,500 cu/m per hour.
"Council has since agreed to go-ahead with the project. We are confident that the project would be complete before the UNWTO meeting. But the pump station would be used long after the event is over," added Jiyane.
“Currently, we are planning on a population of 750,000 people and it might grow hence the need of a new pump station.”


Foot Valve X9121
DESCRIPTION: Foot Valve (Baffle Type Cartridge)
Concept of foot valve
The foot valve is also called a check valve. It is a low-pressure flat valve. Its function is to ensure the one-way flow of the liquid in the suction pipe and make the pump work normally. When the pump stops working intermittently for a short time, the liquid cannot return to the water source tank to ensure The suction pipe is filled with liquid to facilitate the start of the pump.
The foot valve is divided into:spring foot valve,pump foot valve,water pump foot valve：
The foot valve is equipped with multiple water inlets on the valve cover and equipped with a screen to reduce the inflow of debris and reduce the probability of clogging of the foot valve. Although the foot valve is equipped with an anti-clogging screen, the foot valve is generally suitable for cleaning media, and the foot valve is not suitable for media with excessive viscosity and particles.

EASTMANS WETLAND INLET WORKS
HOON HAY - CHCH
Another key aspect of the works at the Eastman’s Inlet was the works associated with managing water flows and ecology management. The works involved creating a temporary diversion of the Hoon Hay Stream to enable the construction of the new structure and earthworks to create the new inlet and outlet channels into the structure.
Once the new temporary stream diversion had been put in place and the section of the existing stream cut off, Dr Tanya Blakely and her team from Boffa Miskell completed fish salvage of the stream. Fish salvage was also completed on the temporary diversion channel before decommissioning once the Hoon Hay Stream could flow through the new structure.
The project's finishing touches included the construction of a gravel walking/bike track over the top of the concrete structure. Once the wider project has been completed, there will be a series of bike and walking tracks around the stormwater management ponds and structures for the wider public to utilise and enjoy.

Pinhook Road Overlay
Public Works Project Number: 1900
Project Length (miles): 1.2
Parish District: 4, 5
Construction Estimate: $2,300,000.00
Project Cost: $2,500,000.00
Project Type: Traffic, Roads & Bridges
The Pinhook Road Overlay project is a road rehabilitation project that aims to improve the condition and functionality of Pinhook Road from S. College Rd. to E. University Ave. One of the primary components of the project is the improvement of the drainage system along the roadway. The existing storm drain system is in poor condition and no longer functioning efficiently. The existing catch basins and manholes will be removed, and new catch basins and manholes will be installed at strategic locations to improve the flow of stormwater runoff, prevent flooding, and reduce erosion. In addition to the new catch basins and manholes, trench drains will be added to improve drainage along the road. Trench drains are important for efficiently capturing and conveying stormwater runoff. The trench drains will be installed at appropriate locations along the roadway to ensure maximum effectiveness. The project will also include drainage improvements such as the installation of pipes and culverts to channel water away from the roadway. The team will work to minimize disruptions to the community during the construction process by scheduling work during off-peak hours and minimizing lane closures.
The graphic below provides a conceptual view of the proposed improvements that will be considered for the project.
DRAINAGE AND GREEN INFRASTRUCTURE CONSIDERATIONS
To address the drainage concerns, the construction team will be removing the existing catch basins and manholes that are in poor condition and replacing them with new ones. This will help to ensure efficient drainage of stormwater runoff and prevent flooding along the road. Furthermore, the project will also replace the existing pipes and install new trench drains to further improve the drainage system along the road. The trench drains will be designed to effectively capture and convey stormwater runoff, reducing the risk of flooding and erosion.
To address the green infrastructure concerns, the team will work to incorporate sustainable design practices into the project. For instance, the construction team may consider adding vegetated swales or bio-retention areas to help filter and manage stormwater runoff, promoting healthier soil, and reducing the heat island effect.
Considerations have been identified and must be reviewed and potentially addressed. Upon research, very minimal impact to the environment will be done with this project.
*Note that this is not exhaustive of possible future environmental considerations.
A preliminary assessment of the project area is provided for the utilities listed below. Potential utility relocation costs will be included in the project budget if the infrastructure is located within the utility’s own servitude.
RIGHT OF WAY CONSIDERATIONS
The current project under consideration does not require any right-of-way acquisition.

SAM (formerly as HALIS) was contracted to provide simultaneous LiDAR and Imagery acquisition of the Fort Patrick Henry Dam and downstream area. SAM contracted with a survey firm to provide field surveys to be utilized in the calibration of LiDAR data and triangulation of imagery.
Data Acquisition for this project included close coordination with dam personnel to ensure that acceptable downstream water levels were achieved. In order to fly with water as low as possible, SAM alerted dam personnel before flight window so that the dam could be closed. Once the dam was closed, data acquisition had to be completed within a four-hour window, starting 20 hours after closure. SAM completed one flight utilizing a helicopter platform for high density dam scan to be utilized in the construction of a 3D model, and a second fixed wing flight during low water conditions to be utilized in the generation of 1′ contour data and color orthophotography.
Project deliverables included DTM and 1′ contours in CADD format, 3D model of the dam in CADD format, orthophotography in TIFF format, and LIDAR Accuracy report in PDF format.
