Main factors affecting groundwater regime

March 17, 2017/ Saul Montoya

The concept of a groundwater regime is based on the fact that the occurrence and distribution of groundwater is not merely a product of chance, but the result of a combination of climatic, hydrologic, geologic, topographic and soil-forming factors that together form an integrated dynamic system. These factors are interrelated in such a way that each provides some insight into the functioning of the total system and thus serves as an indicator of local conditions of groundwater occurrence and distribution (PAEL, 1993).

Main predictive simulations for an EIA in mining

March 17, 2017/ Saul Montoya

Impact assessment of mining projects on groundwater resources can be a challenging task due to uncertainty on groundwater flow regime, the complex numerical tools to successfully simulate stresses on groundwater resources posed by the mining projects, timeframe and budget of EIAs.

In this article, we will call EIA the document issued before the mine begins for regulatory official approval and social license.

Regional Groundwater Modeling with MODFLOW and Model Muse

March 15, 2017/ Saul Montoya

Groundwater modelling can be done on multiple temporal and spatial scales, from a laboratory setup to a complete basin, from steady-state to thousands of years. Each modelling requirement has a specific discretization and boundary condition setup. This tutorial cover a regional groundwater modelling example on a andean basin on steady state conditions, the tutorial covers the whole set of modelling steps as grid generation and elevation import as well as the model simulation and result evaluation. Numerical modelling was done in open source software as MODFLOW with Model Muse, both developed by the USGS.
