In this article we will discuss about:- 1. Meaning of Runoff 2. Types of Runoff 3. Factors Affecting Runoff 4. Runoff Cycle 5. Computation. Meaning of Runoff: Rainfall is the primary source of water for runoff generation over the land surface. In common course of rainfall occurrence over the land surface, a part it is intercepted by the vegetations, buildings [...]
In this article we will discuss about:- 1. Meaning of Runoff Hydrograph 2. Components of Hydrograph 3. Factors Affecting the Shape 4. Base Flow Separation. Meaning of Runoff Hydrograph: Hydrograph is a graphical or tabular presentation of instantaneous runoff/discharge rate against time. Sometimes, it is also known as storm hydrograph, flood hydrograph or simply hydrograph. A hydrograph presents the total [...]
In this article we will discuss about how to compute runoff caused due to rainfall using unit hydrograph. Introduction to Unit Hydrograph: If two identical rainfalls regarding their characteristics take place in a drainage basin having the same conditions prior to the rainfall, the runoff hydrographs from the two storms would be the same. This is the basic concept used [...]
