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:



Geostatistics on water resources investigation

Before talking about the different researches that have had as main focus the water resources, I think it is necessary to explain first what geostatistics is.

Geostatistics is a type of statistics that is used in order to analyze and interpret geographically referenced data. It is not restricted to only work with point data, but can also work with GIS layers to explore spatial variation, improving generation of digital elevation models (DEM) and their respective simulations, optimization of spatial sampling, etc.

Climate change impact on watershed response

Mathematical models of global climate can reproduce many aspects of the physical climate system. General Circulation Models (GCMs) simulate physical processes in the atmosphere, ocean, cryosphere, and on the land surface. Predictive scenarios on climate change will be applied to selected GCM models and their output will be used on the PRMS hydrologic simulations.

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.
