Unit hydrograph method
單位歷線法 -
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，採用dag lohman 34 ， 35發展的匯流模型進行匯流由於是研究地下徑流，所以取每個網格的地表徑流為0 ，該模型採用單位線計算坡面匯流線性聖維南saint - venant equation進行河道匯流 -
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
分析公伯峽流域所處地理位置及該流域內的氣象特徵，確定產、匯流模型採用超滲產流和瞬時單位線，河道匯流採用馬斯京根法，實時校正法由卡爾曼濾波和最小二乘法組成。 -
Cthe method of establishment of spatial analysis information system about water resource in longkou city based on water experiment and observational data and special map, spatial database and attributive database of water resource is established with arc / info7. 1 ~ arcview3. 1 ~ photoshop5. o ~ idrisi2. o ~. visual foxpro5. o. taking horton geomorphology and valdes geomorphicly immectiate unit hydrograph ( g theory ) as theory direction, the database is analyzed and mathematical models is found. linking basic database and model database, that spatial database and attributive database of water resource is established
龍口市水資源時空分析信息系統構建的方法以水利實驗、觀測數據和專題地圖等資料為基礎數據，在arc / info7 . 1 、 arcview3 . 0 、 photoshop5 . 0 、 idrisi2 . 0 、 visualfoxpro5 . 0技術支持下，構建起水資源空間數據庫和屬性數據庫；以g理論和horton地貌律為理論指導，進行數據庫分析，並建立水資源數學計算模型，即模型庫構建；將基礎數據庫和數學模型庫藕合在一起，建立起龍口市水資源時空分析信息系統。
