摘 要: | 在总结目前推求单位线方法的基础上,提出了一种改进的优化方法--约束最小二乘法。它通过Windows平台上的可视化编程,不震拟定初始单位线和试错,就能快速准确达到单位线的最优适配,并能够在计算机上实现推求和修匀单位线。

An Optimum Seeking Method of Least Squares with Constrain for Unit Hydrograph |
| |
Abstract: | Based on the summarization of merits and demerits of exist seeking unit hydrograph methods,this paper presents a modified optimum method named method of least squares with constrain.It need not draw up original unit hydrograph and trial-and-error by making program in windows system.It can optimally fit unit hydrograph quickly and accurately and carry out seeking and smoothing unit hydrograph together in computer. |

Keywords: | unit hydrograph least squares with constrain smoothing visual program |
