Question
Darcy's Law represents discharge of groundwater and has the equation Q=KA/(difference in hydraulic head(h)/distance between two wells(l)) What is the discharge of groundwater in a highly dissolved limestone squifer with the following properties

farmlands contribute the most to sediment pollution in water bodies
-
sediments in a water body reduce the amount of sunlight that can penetrate the water body and reach bottom dwelling plants
