The artificial neural network ( ann ) method is studied for use in river channel flood forecasting , the result show that the method can be applied in practice 论文探索了人工神经网络方法( ann )在河道洪水预报中的应用；该结果具有一定实用前景。
Because of serious sedimentation for the downstream section of the wei river , the conventional forecasting method cannot get satisfactory results 在探讨了gis与图形交互技术的应用方面，有所前进。渭河下游河道淤积严重，一般洪水预报方法效果不佳。
At the same time , it has great use in a lot of fields , such as flood control of city , flood forecast analysis and water resources continuable use 同时，对于城市的防洪规划、洪水预报分析、河道演变规律及水资源综合利用等有着十分重大的意义。
The application of remote sensing . gis and gps techniques to hydrology , water resources and water conservancy projects as well as hydrologic plot experiment and flood forecast 遥感技术、地理信息系统技术和gps技术在水文、水资源和水利工程中的应用，以及水文径流试验和洪水预报等。
( 2 ) the risk of flood operation mainly comes from the errors of flood and rainfall forecast , in the next place , the errors comes from the decision - maker ' s subjective preference ( 2 )水库汛限水位动态控制中的风险主要来自洪水预报和降雨预报的误差，其次来自决策者的决策误差。
Meanwhile , theory of artificial neural network ( ann ) is introduced into runoff forecasting of shuicehng reserior . artificial neural network model is established to apply to runoff forecasting 同时将人工神经网络模型引进到水城水库的洪水预报中，建立了人工神经网络预报模型。
As for controlling flood , accurate and timely flood forecast is the most important task . we can get more time and take more reasonable measures to avoid flood disaster 对于防洪工作来说，最重要的工作是要有精确、及时的洪水预报，为防洪争取更多的时间和采取更合理的措施来避免洪水灾害。
The method based on the principle of maximum entropy ( pome ) is applied to analyze the distributions of flood forecasting errors for some typical reservoirs in humid and semi - humid regions 摘要采用最大熵原理( pome )方法，对我国湿润和半湿润地区部分典型水库的洪水预报误差分布规律进行了研究。
The prediction period of flood forecast is decided by the flood propagation time to a great extent , and its shorter or longer play an important role in decision of construction scheme during flood period 洪水预报的预见期主要由水量传播时间决定，预见期的长短对施工渡汛方案的制定有决定性作用。
Flood forecasting is an important nonstructural measure of natural disaster prevention and alleviation . the traditional flood forecast methods are relatively complex and hard to be popularized 洪水预报是一项重要的防灾减灾非工程措施，而以往的洪水预报方法较为复杂，建模工作要求较高，不易普及。
