洪水预报调度是水利水电工程建设中一项重要的非工程性措施,它对确保工程的安全运行起着重要作用。同时,它又是重要城市防洪或水工建筑物进行水科学管理的必要手段。准确及时的预报可使工程合理调度,及时采取防洪抢险措施,力求使洪灾损失限制到最低程度。因此,洪水预报调度是目前世界各国十分重视的一项投资少、效益大、见效快的重要经济活动。洪水预报是当今水文水资源学科中一个重要的分支。它根据流域上发生的暴雨或河流上游的来水,经过水情信息采集、传输、存贮、处理和一系列的科学计算,最终预估在其一控制断面即将发生的实际洪水过程。由于洪水预报要求预报洪水准确、及时,因此,它又是一门技
Flood forecasting and dispatching is an important non-engineering measure in the construction of hydropower projects, which plays an important role in ensuring the safe operation of the project. At the same time, it is also a necessary means of flood control or hydraulics in key cities for water science management. Accurate and timely forecasts can make the project a reasonable schedule, timely flood control and rescue measures, and strive to make the flood damage to a minimum. Therefore, flood forecasting and dispatching is an important economic activity that has paid great attention to all countries in the world for less investment, more benefit and quicker result. Flood forecasting is an important branch in today’s hydrology and water resources. Based on heavy rainfall in the river basin or incoming water upstream of the river, it acquires, transmits, stores, processes and a series of scientific calculations of hydrological information and finally estimates the imminent actual flood process at a control section. Since flood forecasting requires accurate and timely flood forecasting, it is another trick
