Movement of Soil Water (With Equation)
Article shared by :
1. Torricelli’s Equation: When the water level falls through a distance Z, the velocity of its flow (v) at depth z, as described by Torricelli’s equation, is equal to the velocity acquired by water due to the fall of water level. 2. Bernoulli’s Equation: In flooded or saturated soil when water moves under hydrostatic pressure […]
Loss of Water from Soil: 2 Processes
Article shared by :
This article throws light upon the two processes by which water is lost from soil. The processes are: 1. Percolation Losses 2. Evapotranspiration. Process # 1. Percolation: The losses of soil water through percolation are maximum under humid climate where precipitation is high. Different essential plant nutrients are lost from soils through such percolating water. […]
