In this article we will discuss about:- 1. Procedure to Separate Base Flow 2. Methods to Separate Base Flow 3. Base Flow Separation of a Complex Storm. The flood hydrograph observed during the storm is a combination of the flood runoff and the base flow. It is necessary to study the excess rainfall and its […]
Changing of Time of Unit Precipitation | Water | Irrigation | Agriculture
Article shared by :
At time, the time of excess precipitation in case of a unit hydrograph, keeping the unit precipitation the same, is required to be changed depending upon the storm period t. This time of excess precipitation may be increased or decreased. Suppose the unit hydrograph of 1 h-1 cm precipitation is available as follows: A 2 […]
