 Groundwater Flow – Physical Geology

Groundwater Flow – Physical Geology

V = K * i. (where V is the velocity of the groundwater flow, K is the hydraulic conductivity, and i is the hydraulic gradient). We can apply this equation to the scenario in Figure If we assume that the permeability is m/s we get: V = * = m/s. That is equivalent to m/min, m/hour or m/day.

Chapter 5: Flow Nets | HWB

The construction of flow nets is one of the most powerful analytical tools for the analysis of groundwater flow. In Section and Figure, we saw that a flow net can be viewed as the solution of a twodimensional, steadystate, boundaryvalue problem. The solution requires knowledge of the region of flow, the boundary conditions on the ...
