Introduction to Python and Geopandas for Flooded Area Analysis - Tutorial

May 24, 2024/ Saul Montoya

Geopandas is one of the most advanced geospatial libraries in Python because it combines the spatial tools of Shapely, it can create and read different OGC vector spatial data, it can couple the Pandas tools to manage, filter, and make operations over the columns of the metadata, it has the capability to plot geospatial data on Matplotlib and even to Folium among other features. We have developed a tutorial of Geopandas applied to the analysis of flooded areas over the Boise city for a return period of 200 years; the tutorial covers introductory concepts of Geopandas, it will work with point, line and polygon vector data, create plots, simplify vertices and perform geospatial queries over inundated facilities and highways.

Groundwater Flow Simulation at Mine Closure Time Scale with MODFLOW and Model Muse

December 01, 2017/ Saul Montoya

This tutorial deals with the simulation of the groundwater flow regimen after the implementation of mine closure options as soil/geomembrane cover above a Tailings Storage Facility (TSF) over a period of 80 years with results every 4 years. The tutorial deal with a full steady flow model which have been implemented to transient conditions on the model configuration and boundary conditions. A discussion of the seepage with time and final conditions after closure is presented to analyse the efficiency of the closure techniques.

Environmental flow determination by hidrological modeling

March 17, 2017/ Saul Montoya

The world water legislation has a common challenge: distribute fresh water resources in a fair, efficient and sustainable way. Traditionally, agriculture, industry, mining and municipalities have competed for these limited resources.

Climate change impact on watershed response

March 17, 2017/ Saul Montoya

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 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

March 17, 2017/ Saul Montoya

Water balance is known as the balance of water entering the system and the water that leaves within a specified time, but 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.

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.

Groundwater monitoring system implementation

March 17, 2017/ Saul Montoya

A monitoring system is a platform where level and quality records that describe groundwater resources are generated, made available and evaluated. These records are consistent, representative and long lasting. Managing the aquifer to local or regional level is required in order to have environmental managers with easy access for comprehensive, representative and reliable information.
