Difference between groundwater and surface water
groundwater, surface water, and the atmosphere, but also flux boundaries from one reservoir to another. Groundwater is defined as water within saturated pores in the subsurface. As such, the flux of water between groundwater to surface water (q) is governed by the equation for saturated flow in porous media, Darcy’s Law (equation 1):Overview Science Multimedia Publications A huge amount of water exists in the ground below your feet, and people all over the world make great use of it. But it is only found in usable quantities in certain places underground — aquifers. Read on to understand the concepts of aquifers and how water exists in the ground.
