軟件包括推理公式法、單位線法、平原排澇公式法三種由暴雨資料推求設計洪水的計算方法，除了適用于河南省中小流域設計洪水外，推理公式算法、平原區排澇公式算法也可在鄰近省市和更大的范圍內推廣使用。
• Through examination of the recession limbs of the observed hydrographs , during periods with no rain and thus no surface runoff , one can determine the value of . for this catchment , a value of 0 . 8 is obtained . the simulated subsurface runoff at each grid is routed to the outlets through a unit - hydrograph method for overland flow and the linear saint - venant equation for channel flow to get the discharge at xixian station
對所研究的流域而言,經過估算消退系數為0 . 8 .耦合著這兩種不同地下徑流機制的clm模型都可以計算出每個網格的地表地下徑流深,采用dag lohman 34 , 35發展的匯流模型進行匯流由于是研究地下徑流,所以取每個網格的地表徑流為0 ,該模型采用單位線計算坡面匯流線性圣維南saint - venant equation進行河道匯流
• The geomorphological instantaneous unit hydrograph ( giuh ) is viewed as the frequency distribution of the times of arrival of individual water deoplets at the catchment outlet . the travel path , for a typical hillslope cell . consists of a hillslope fraction , corresponding to overland flow and a stream fraction , corresponding to concentrated channeled flow . to obtain the time of travel , velocities must be defined . hillslope and stream velocities vary with location and must be strongly correlated with slope , and therefore a spatial distribution of velocities and hence of travel times could be obtained . the present methods of giuh neglect any time delays associated with overland flow pathways
地貌單位線被看作是流域上各水質點在弱相互作用下，到達流域出口匯流時間的頻率分布。對于一個典型的山坡型網格單元，匯流路徑由兩部分組成，即坡地部分和河道部分，為了得到匯流時間，必須首先確定匯流速度。坡地和河道的匯流速度隨著區域位置而變，并且必然與坡度有關，因此，可首先計算流速的空間分布，進而得到匯流時間的空間分布。
• Geography position and meteorology character in gongboxia watershed are analyzed , according to which the excess of infiltration and instantaneous unit hydrograph are used in runoff and affluence models , and muskingum routing method in river course affluence , kalman filtering technique and least square method in real - time correction
