PPT-Steady flow in a confined aquifer

From Mays 2011 Ground and Surface Water Hydrology If the distance and the observed piezometric surface drop between two adjacent wells are 1000 m and 3 m respectively find an estimate of the time it takes for a molecule of water to move from one well to the other K is 35 mday and effective porosity is 035 .

Introduction. Partially penetrating wells:. aquifer is so thick that a fully penetrating well is impractical. Increase velocity close to well and the affect is inversely related to distance from well (unless the aquifer has obvious anisotropy). Basic Assumptions. Aquifer bounded on the bottom. Horizontal Geologic Formations (with infinite extent). The potentiometric surface is horizontal and is steady prior to pumping. Any changes in potentiometric surfaces are due to pumping .

Methods for determining aquifer parameters. In Unit 2 we discussed about various lab and field methods for determining the hydraulic conductivity values for the soil/rocks.. Methods included the use of constant head Permeameter, falling head Permeameter and tracer tests for determining the K..
