draining point 中文意思是什麼
-
Topmodel is based on the calculation of ln ( / tan # ) index and its distribution. in terms of a dem, a is the cumulative upslope area draining through per contour length to a pixel, which reflects the tendency of water to accumulate at any point in the catchment, tan # is the local slope angle of the cell, which reflects the tendency for gravitational forces to move that water downslide
Topmodel是以計算ln ( tan )指數及其分佈為基礎的。對于柵格dem ,為上坡區域通過單位等高線長匯集到單元網格內的面積,反映徑流在流域中任一點的累積趨勢, tan為單元網格的坡度,反映重力使徑流順坡移動的趨勢。
