HSAG Calculating Groundwater Velocity Unconfined Aquifer

Observe the movement of water through an unconfined aquifer and calculate its groundwater velocity.

Boussinesq, unconfined groundwater flow on a sloping aquifer bottom

A nice example of groundwater flow on an inclined sloop. The data are in the title of the figure. We start with some initial head which is a sine between the two head boundaries at the top...
