Detailed explanation-1: -Temperature, wind speed, and humidity are the major meteorological factors, which affect runoff. Temperature, wind speed and humidity affect evaporation and transpiration rates, thus soil moisture regime and infiltration rate, and finally runoff volume.
Detailed explanation-2: -The Rational Formula is expressed as Q = CiA where: Q =Peak rate of runoff in cubic feet per second C =Runoff coefficient, an empirical coefficient representing a relationship between rainfall and runoff.
Detailed explanation-3: -Runoff is a major source of water pollution. As the water runs along a surface, it picks up litter, petroleum, chemicals, fertilizers, and other toxic substances. From California to New Jersey, beaches in the U.S. are regularly closed after heavy rainfall because of runoff that includes sewage and medical waste.
Detailed explanation-4: -surface runoff (water flows above the ground’s surface), interflow runoff (water flows underground just below the land’s surface), and. base flow runoff (water flows deep within the ground’s saturated zone). 26-Aug-2021
