Basic Example of Stream Flow Routing (SFR) Package with MODFLOW and Model Muse

The disconnexion of surface groundwater flow it is fact very common on highly exploited aquifers or under impacts from climate change. Many rivers are disconnected from the groundwater flow regime decreasing their flow amount due to infiltration losses. For the simulation of this surface flow, unsaturated flow and groundwater flow phenomena the MODFLOW package Streamflow Routing (SFR) was developed.

This tutorial develops an numerical model of disconnected surface groundwater flow with MODFLOW SFR and Model Muse. The study case has regional flow and a river network with monthly flow on transient conditions over 2 years.
