Darcy law of groundwater flow

WebThe hydraulic conductivity(K) in Darcy’s law influences every aspect of groundwater flow. It impacts the flow velocity, dicharge, travel time and direction of flow. K may be dtermined by collecting soil or rock samples and runing laboratory flow tests or by one well tests or mulitple well pumping tests. Each has advantages and disadvantages. WebDarcy’s Law.
