水文测量.大河和洪水流量的野外测量 - All the method hare been proved in project to improve the accuracy of designimy rolume of fold when they are used in practice they will also improve the accruing of any desighmy river - crossing bridge
上述方法经过工程实际验证，表明可提高设计洪水流量的精度，在工程中的应用将提高跨河桥梁设计的精度。 - Mathematical model is used to calculate and analyze water line in case of 9 kinds of flood flow levels respectively in reservoir . there are two programs including with enclose tideland for cultivation and without it in every flow level
利用数学模型分别对9个洪水流量级进行了水库沿程水面线计算分析，每个流量级分有围垦堤和没有围垦堤两个方案。 - 3 . a new runoff forecasting model , based on the combination of genetic algorithm and neural network , is proposed , which integrate with the strongpoint of genetic algorithm and neural network . the accuracy and the speed of runoff forecasting are effectively improved that offered a new method for solving runoff forecasting problem
3 .提出了基于遗传算法的神经网络洪水流量的预测模型，该模型综合遗传算法和神经网络的优点，有效地提高了预测精度和速度，为洪水流量预报问题提供了一种新的方法。 - When catchment area , average channel gradient and catchment shape factor of designed culvert or bridge are known , a user can be convenient to get local parameters c , e and b from standard contour charts and easy to calculate flood flow just by a calculator . design period of flood flow is enormously shortened as well as a high precision . estimated flood flow through culvert or small bridge by new calculation model is generally less than by traditional methods , so that much cost is cut down a s reducing the span of culvert or small bridge
以75000km ~ 2的川中丘陵地区为试点研究区，绘制了该地区新模型的参数等值线图，率定了不同设计频率的改正系数，使设计者只需在地形图上获取集水面积，河道平均坡降和流域形状系数，在参数等值线图上查得桥涵所在地的相应参数，使用计算器即可迅速计算出设计流量，大大缩短了设计周期，且精度较高，设计的洪水流量一般低于传统方法，从而可减小桥涵跨径，节省投资。
