伊东渠灌区位于洛阳市龙门伊河东岸,渠首位于伊川县西草店村河滩,干渠全长31.5km,设计灌溉面积7200hm2,有效灌溉面积4560hm2。伊东渠自兴建以来,为两岸群众在灌溉、水产等方面提供了强有力的保障,发挥了巨大的经济效益和社会效益,但由于灌区运行时间较长,工程老化失修,部分骨干工程不能正常运行,渠道淤积、渗漏现象十分严重,引水、输水能力不足,灌区控制能力逐年下降。为改变这种状况,需要对灌区进行节水改造。为搞好节水改造规划,对灌区需水、供水及水量平衡进行了分析。
The Itoqu irrigation district is located on the east bank of Longmenyi River, Luoyang City. Its drainage head is located at the floodplain of Xicaopian Village in Yichuan County. The total length of the main canal is 31.5km. The designed irrigated area is 7200hm2 and the effective irrigated area is 4560hm2. Since the establishment of Ito-Dong Canal, it has provided strong protection for irrigation and aquatic products of the people on both sides of the Straits and has exerted tremendous economic and social benefits. However, due to the long operation period in the irrigation areas, the aging of the project is out of repair and some of the key projects can not be normal Run, channel siltation, leakage is very serious, water diversion, lack of water delivery capacity, irrigation control capacity declined year by year. In order to change this situation, it is necessary to make water-saving transformation of irrigation districts. In order to do a good job of water-saving transformation planning, water demand, water supply and water balance in the irrigation area are analyzed.
