| Abstract from DBPedia | Hydraulic engineering as a sub-discipline of civil engineering is concerned with the flow and conveyance of fluids, principally water and sewage. One feature of these systems is the extensive use of gravity as the motive force to cause the movement of the fluids. This area of civil engineering is intimately related to the design of bridges, dams, channels, canals, and levees, and to both sanitary and environmental engineering. Hydraulic engineering is the application of the principles of fluid mechanics to problems dealing with the collection, storage, control, transport, regulation, measurement, and use of water. Before beginning a hydraulic engineering project, one must figure out how much water is involved. The hydraulic engineer is concerned with the transport of sediment by the river, the interaction of the water with its alluvial boundary, and the occurrence of scour and deposition. "The hydraulic engineer actually develops conceptual designs for the various features which interact with water such as spillways and outlet works for dams, culverts for highways, canals and related structures for irrigation projects, and cooling-water facilities for thermal power plants."治水（ちすい）とは、洪水・高潮などの水害や地すべり・土石流・急傾斜地崩壊などの土砂災害から人間の生命・財産・生活を防御するために行う事業を指し、具体的には、堤防・護岸・ダム・放水路・遊水池などの整備や、河川流路の付け替え、河道浚渫による流量確保、氾濫原における人間活動の制限、などが含まれる。 (Source: http://dbpedia.org/resource/Hydraulic_engineering) |
