GeoLinkage2.0 and GeoChecker: Hydroinformatics tools for large and complex hydrological-hydrogeological models using WEAP-MODFLOW. Case Study: Severe drought in the Limarí River Basin, Chile Open
Understanding and modeling surface and groundwater resources are critical due to the effects of droughts and climate change, especially in semi-arid, arid, or hyper-arid regions. GeoLinkage, developed by Troncoso (2021), facilitates the cr…

Improvement in the subterranean knowledge of the Limarí river basin to support decision making in the context of drought. Open
Water scarcity has 35% of Chile's population under a severe drought for over a decade. Local communities formed by users of surface or groundwater resources have been pushing to reach agreements prioritizing human consumption and ecosystem…

Artificial recharge effects in water balance of a peri-urban semi-arid catchment: a case study in an Andean aquifer using WEAP-MODFLOW Open
<p>Artificial recharge in urban and peri-urbans areas is not a typical practice, but the prolonged severe drought in central Chile has encouraged the study of this practice as an option for optimal and sustainable water management. T…

GeoLinkage: a GRASS-GIS plugin to integrate surface waters and groundwater in WEAP-MODFLOW models Open
<p>Water resources management requires specialized computer tools that allow explicit integration of surface and groundwater fluxes, which generally have domains with different spatial discretization. On one hand, a surface hydrologi…

Impact of Urban Growth and High Residential Irrigation on Streamflow and Groundwater Levels in a Peri‐Urban Semiarid Catchment Open
The impact of urbanization on groundwater is not simple to understand, as it depends on a variety of factors such as climate, hydrogeology, water management practices, and infrastructure. In semiarid landscapes, the urbanization processes …

Representation of the Drainage Network in Urban and Peri‐urban Areas Using a 2D Polygonal Mesh Composed of Pseudo‐convex Elements Open
This chapter presents a module implemented in QGIS, belonging to the GEO-PUMMA toolbox. This plugin allows a triangulation of surface elements with a vectorial format, and thus the segmentation of a mesh composed of heterogeneous polygons.…

A GIS-based urban and peri-urban landscape representation toolbox for hydrological distributed modeling Open
Flowpaths are significantly affected by land use change and engineered elements across urban catchments. Conventional GIS-based tools for extracting drainage networks were not developed for urban terrains. This work presents Geo-PUMMA, a G…
