摘要
为了对小流域的降雨径流预报方案进行研究,选取湖南省面积为22.1 km2的清水流域为研究对象,产流方案采用C语言编写的程序来实现。对产流方案所模拟的13场洪水进行分析,模拟结果均较好,合格率为83.3%;汇流方案根据降雨历时以及汇流时段的不同,有2条单位线可供选择,用于复核单位线的洪水都取得了较好的模拟结果。设计的降雨径流预报方案在清水流域是完全适用的。
In order to research the rainfall-runoff forecasting program of small watershed, the Qingshui River Watershed with a area of 22.1 km^2 in Hunan Province is selected as study case, and the runoff generation progam is achieved by C language program. The simulations of thirteen floods by runoff generation program show that the results are good and the pass rate is 833%. Since the rainfall duration periods and the flow time of concentration are different, there are two unit hydrograph to be chosen in flow concentration program. The simulations of floods by flow concentration program have achieved a relative good result. This rainfall-runoff forecasting program is completely applicable in Qingshui River Watershed.
