Since the water level drops fast during the first one or two hours of the test, readings should be taken at short intervals which are gradually increased as the pumping continues. Fairly accurate measurements of water level can be made by using an electric sounder, by the wetted tape method (the steel tape is coloured […]

The selection of a proper pumping set is important to ensure continued satisfactory yields from wells and the factors to be considered are: (i) Finished inside diameter and total depth of the well. (ii) Yield from the well, the desired pumping rate and hours of pumping per day. (iii) The lowest pumping water level (in […]
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 […]
