Inverted Auger Hole Method Above Water Table

2 Inverted Auger Hole Method (Above Water Table) 

A hole is bored to the desired depth and a constant head of water is maintained in the hole. The fall of water level in the whole is measured rmder steady state condition. 

The initial depth of water inside the hole at time to (min) = h m. 

Determine the slope of the curve by plotting log vs ti. This is the value of tan 9
