There are many methods of estimating evapotranspiration. Some of these are briefly described in the following: 1. Soil Moisture Sampling: A large number of samples are taken from various depths in the roots zone and the soil moisture depletion studies are made. 2. Tanks and Lysimeter Experiments: Keeping an account of water added and soil […]

How to Calculate the Velocity of Ground Water Flow? | Geography
Article shared by :
Ground water moves from levels of higher energy to levels of lower energy, its energy being essentially the result of elevation and pressure, the velocity heads being neglected since the flow is essentially laminar. The velocity is very small in the laminar range—of the order of 1 cm/sec—and the Reynolds number (Re) for ground water […]
Top 3 Surface Methods of Geophysical Investigations | Geology
Article shared by :
Geophysics, in the past few years, has reached a place of vital importance to the scientific development and protection of the world’s precious ground water supply. Geophysical investigations of the buried strata can be made either from the land surface or in a drilled hole in the formation. The surface methods include: 1. Electrical Resistivity […]
