Question

Consider steady flow through a layered soil column of cross-sectional area A as shown below. Soil 1 Soil a rm 2. The specific discharge through the column is v=Q/A Derive a formula for the pore water travel time through the column. The concept of an "equivalent" or "effective" homogeneous system is very important in groundwater studies. Let's replace the above layered system by an equivalent homogeneous system. The pore water velocity (seepage velocity) of the equivalent homogeneous soil column is defined as V-v/ny where nea is the porosity of the equivalent soil column. Derive an expression for neg.
