Groundwater app to determine flow direction and gradient.A computational program, called the groundwater flow calculator, was created to quickly and easily determine the hydraulic gradient and direction of groundwater flow.  The groundwater flow calculator automates the hand-drawn process by Ralph Heath in the U.S. Geological Survey (USGS) Water Supply Paper 2220.
