MODFLOW is a software for groundwater modeling developed by the USGS. The software is capable of representing conditions related to groundwater flow such as evapotranspiration, recharge, drainage, river interaction among others. Its finite different approach gives the capability to calculate the flow regime with exceptional control on water budget discrepancy. With MODFLOW one can rely on that the flow going in the model is the same as the flow going out of it, from the regional scale and on cross sections.

Continue exploitation of groundwater in arid climates generates extreme scenarios of groundwater flow and storage. As pumping rate increase, inflows from recharge, storage and seawater increase.  With time, seawater is introduced into the aquifer, reaching its wells and affecting water quality. This tutorial shows the impact of intense groundwater exploitation of 50 wells in a simulation period of 60 years.

Interesting tutorial for the transformation of a 3D numerical groundwater flow model done with MODFLOW into a lightweight 2D model. The case of study is a groundwater flow model of tailing seepage done with horizontal discretization from 50 to 12.5m and 21 layers. The tutorial cover spatial object and dataset treatment together with some discussion on the model construction and discretization.

Interesting modeling exercise of groundwater well interference with MODFLOW. This tutorial is made from the ground up with the input files and a discussion over the results. Three pumping were considered with rates form 5 to 10 l/s. Simulation period was set up to 15 years  and interference was analysed over 1, 3, 5,10 and 15 years.
