There are many empirical formulae for the estimation of annual rainfall penetration (AMP), but those are not universal in their application and also regarding their methodologies. Datta et al (1973) have attempted in a classical way for assessing annual rainfall penetration with the help of annual rainfall and average clay percentage of topsoil. In the […]
Rainfall recharge
A new approach for estimation of rainfall recharge from prolonged infiltration rate and effective monsoon period
To study the rainfall recharge during effective monsoon period an experiment was conducted during 140 days of effective monsoon in the year 1990 at Kalyani, Nadia district, West Bengal, India. The potential recharging capacity of that soil was found to be 7729 cm by continuous supply of water, while the recharge during the period of […]
In quest of a pattern in annual rainfalls
Heat from the sun vis-à-vis evaporation and rainfall: Cause and effect Sun is the source of all energies. Heat from the sun is the driving force in the earth’s hydrological cycle. It is due to the attraction of the sun that earth and the other planets move in their respective orbits. The amount of heat […]
