Unit hydrograph method 單位歷線法
Forest ecosystem ; hydrological system ; global change ; guandaushi watershed ; instantaneous unit hydrograph 森林生態(tài)系、水文系統(tǒng)、全球變遷、關刀溪集水區(qū)、瞬時單位歷線
The results show that the minus value and fluctuation of unit hydrograph can be mitigated and the error of observed discharge can be withstood using the robustified ridge estimation 最后采用抗差嶺估計來推算單位線,該方法既可以解決共線性的問題,也可以抗御粗差的影響,得到比較穩(wěn)定的單位線。
According to the collected data in first two years , the study tried to simulate the runoff model by the instantaneous unit hydrograph theory and analyzed the data , the results were shown as follows 本文系以瞬時單位歷線為基礎,進行逕流歷線之模擬,同時將分析整理前兩年之觀測資料,所得之初步結(jié)果列述如下:
