Well hydraulics

well logging geology earth science

1. What is well hydraulics? To understand he process in effect when one or more well are pumping from an aquifer. This is for instance considers the analysis of drawdown due to pumping with time and distance.

2. Importance of well hydraulics Groundwater withdrawal from aquifer are important to meet water demand. Therefore, we need to understand well hydraulics to design a pumping strategy that is sufficient to furnish the adequate amount of water.
