Why is MODFLOW better than other softwares for groundwater modelling?

 

MODFLOW is the groundwater modelling software developed by the U.S. Geological Survey (USGS). It appeared in 1984 and has had a constant developement till now. MODFLOW's capacities allow the representation of regional or local groundwater flow and its interaction with superficial water bodies.

To learn MODFLOW with MODEL MUSE

 

MODFLOW is the software for groundwater modeling developed by the USGS. The software is capable of representing conditions related to groundwater flow as evapotranspiration, recharge, drainage, river interaction among others. Its finite different approach gives the capability of calculating the flow regime with exceptional control on water budget discrepancy.

Development of a watershed-based water balance

 

Water balance is known as the balance of water entering the system and the water that leaves within a specified time, however, in order to understand it better we need to understand: what is a watershed? Unterstood as a whole, a unity, as a system, as the space bounded by the union of all the headers that form the main river through the territory drained by a single natural drainage system.

 

 

Case studies of watershed-based water balance

 

A watershed can be defined as “the topographic area within which apparent surface water runoff drains to a specific point on a stream or to a waterbody such as a lake” (Shimon, 2010), in this way a watershed works as a large water collector converting water inputs into runoff and water storage (Chavarri, 2012).
