In this article we will discuss about:- 1. Units of Hydrograph 2. Area of Hydrograph 3. Complex Storm 4. Isolated Storm. A hydrograph may be defined as a graphical representation of time versus discharge. Fig 2.10. Units of Hydrograph: The unit for time on the x-axis may be: 1. Hours. 2. Days. 3. Months. This unit is selected depending upon [...]
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 corresponding runoff from a catchment. [...]
