Inside one of largest capacity drainage pump stations in the world

The biggest technological task in flood control is how rapidly storm water on a wide flat land can be drained to pumping stations and/or to the sea. A pressurized underground drainage pipeline system is most effective because it provides a wave transmission speed of about 500 m/s and can respond to the water flow from upstream – much better than a typical open canal with the transmission speed of only about 3 m/s. Hideki Kanno of Ebara Corporation takes World Pumps inside the performance of a large capacity flood-control pipeline system established in the greater Tokyo metropolitan area.

有限要素法による小水路を考慮した農地氾濫モデル

Drainage improvement projects in agricultural fields such as improvement of drainage channel and pump station have been carried out to prevent the influence of inundation for yield amount. In this research, finite element model in consideration of drainage channel and road was constructed, and the movement of the farmland drainage was analyzed. In this model, farmland which is delimited by drainage channel and road was assumed as a block. Then, flow in drainage channel and each block was modeled by one-dimensional unsteady flow model and two-dimensional shallow flow model, respectively. The introduction of present model makes it possible to forecast the inundation of the agricultural fields without dividing into small finite elements for the reproduction of drainage channel and road.

Analysis of the Vibration Propagation Characteristics of a Large Capacity Drainage Pump Station by Using Finite Element Method.

The vibration propagation characteristics of a large capacity drainage pump station were analyzed by using finite element method in a frequency range of 0-100 Hz. The results were compared with the measured ones and they showed good agreement. The factors that may influence the accuracy of analysis were also investigated. It was demonstrated that (1) the spring constants of the ground have influence only on the results of analysis at low frequency, so that the ground can be modeled as a clamped boundary condition when doing response analysis at high frequency, (2) the damping ratio is frequency dependent and it does not have much influence on the results of analysis at locations near the excitation source, but it has great influence on those at locations away due to the very high mode density. Furthermore, it was demonstrated that the responses at locations near the excitation source can be calculated by analyzing only one portion of the structure.

Dynamic control of the Delfland polders and storage basin, The Netherlands

In regional water systems such as those in the Netherlands, a large number of interests with commonly conflicting requirements are involved. Dynamic control offers a way of controlling these complex water systems, making use of the dynamics of the water system. Dynamic control can deal with the entire water-related environment, including all different interests present. This advanced control technique is based on optimization and achieves more efficient operation of a water system because all capacities available in the system can be fully used. When new requirements of any interests in a water system emerge, the traditional solution is to build new water-management infrastructure or extend the existing infrastructure. The application of advanced control techniques shows that this may not always be necessary. For the Delfland water system, a case study shows how dynamic control can be used to balance the interests present and continually match the water system state with the requirements. The case described demonstrates how dynamic control can be used to reduce undesirable water-system behavior during periods of excessive precipitation or drought. Current town and country plans imply an increase in the impervious surface in Delfland in the near future. If the current control practice continues, installation of extra capacity at existing drainage pumping stations would be needed, or even construction of entirely new pumping stations or extra storage facilities. Application of dynamic control makes it possible to use the current capacities in the water system more efficiently and thus avoid large capital investment which otherwise would be necessary in the future.

Toward optimal land drainage pumping

Between 1979 and 1989, the Institute of Hydrology (IH) undertook research into the way in which land drainage pumping stations interact with their feeder drain networks. This work included the extensive field instrumentation of two pumped catchments in central eastern England. This paper describes the work undertaken at one of those catchments, the Boy Grift drain network and pumping station, between August 1986 and March 1989. While brief descriptions of the field equipment are included, the objective of the paper is to illustrate the scope for improving the operation of a land drainage pumping station by pumping the same volume of water at a reduced cost. The relative merits of avoiding pumping against high tides and during periods of expensive electrical supply tariff are assessed. The ways in which these two constraints conflict, are demonstrated and suggestions made toward optimal land drainage pumping.
