The Run-off available from a basin can be computed daily, weekly, monthly or yearly. Following are the methods which can be used for finding out the run-off: Method # 1. Run-Off by Using Empirical Formulae and Tables: a. Run-Off Coefficient Method: The volume of run-off can be directly computed approximately by using an equation of the form - R = [...]
Run-off is defined as the portion of the precipitation that somehow makes its way towards rivers or oceans etc. as surface or sub-surface flow. The discharge flowing in a river is the run-off from the basins drained by that river. The terms discharge, stream flow, and run off all refer to the same thing. When rain falls, a part of [...]
In this article we will discuss about:- 1. Introduction to Unit Hydrograph 2. Assumptions in the Theory of Unit Hydrograph 3. Construction 4. To Develop Storm Hydrograph 5. Use 6. Limitations. Introduction to Unit Hydrograph: The basis of unit hydrograph is that if two identical rainfalls occur on a drainage basin having identical conditions prior to the rains, the hydrograph [...]
