In this article we will discuss about the hydrograph representing run-off of rainfall, with the help of suitable diagrams. Hydrograph is defined as a graph showing discharge (run-off) of flowing water with respect to time for a specified time. Discharge graphs are known as flood or run-off graphs. Each hydrograph has a reference to a particular river site. The time [...]
In this article we will discuss about the hydrologic cycle with the help of a suitable diagram. Most of the earth's water sources, such as rivers, lakes, oceans and underground sources, etc. get their supplies from rains, while the rain water itself is the evaporation from these sources. Water is lost to the atmosphere as vapour from earth, which is [...]
In this article we will discuss about the methods to measure run-off from rainfall over the catchment area. Also learn about the curves representing run-off data with the help of suitable diagrams. Methods to Measure Run-Off: 1. From Rainfall Records: In this method consistent rainfall record for a sufficiently long period is taken and then average depth of rainfall over [...]
