Need help on Hantush equation
(OP)
Hi guys:
Recently I had come across on mounding analysis. And, everyone know that people are using ‘Hantush’ equation to do the analysis. But, in the formula there are two valuables I am having trouble to figure them out. To be more specify is the initial calculation without field data.1. Hydraulic Conductivity. 2. Specific Yield. Is there anyway I can figure out those two valves?
thank you.

RE: Need help on Hantush equation
Specific yield is the amount of water that drains out of one m^2 of the aquifer when you lower the water table by 1 m. It is less than the porosity because some water is held back by capillary effects. In clean gravel, it is pretty close to the porosity (up to 0.35 or so). In clay, it is practically zero, since ALL of the water is usually kept in place by capillarity.

Do a sieve, get the D20 (or D10) size and enter the chart to get the hydraulic conductivity.
For information on Specific Yield, look at Figure 2-5 at this reference:

Hope this helps.
