Seepage flow modeling from mine waste dump with MODFLOW

This example is a simulation of a mining dump, which is a continuous source of concentrated leachate.

Hydrogeological complexities to consider: heterogeneity of the aquifer and the presence of fractured rock.

Groundwater system parameters:



Assessment of land subsidence from pumping


The MODFLOW SUB-WT code has been developed to simulate vertical compaction in regional groundwater flow models because due to pumping. MODFLOW SUB-WT can simulate changes in groundwater storages and compaction in discontinuous layers or extensive confining units. The MODFLOW SUB-WT modeling code considers the compaction of a particular layer of the numerical model as a function of effective effort changes in the layer.

How to be a senior hydrogeologist in 6 years


When I was in second semester of my master degree, the course director gave me this advice: “Learn MODFLOW and you will have a job”. That was a small and sincere advice that helped me on the last eight years as hydrogeologist – numerical modeler. Nowadays, I want to give the guidelines for the interested people of how to be a senior hydrogeologist in 6 years.




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.

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.
