Geographic Information Systems (GIS) are a powerful platform to develop solutions in water resources such as the estimation of water quality, the status of groundwater and the management of water resources at the regional and local scales. Because water varies spatially and temporally throughout the water cycle, its study, using Geographic Information Systems (GIS), is particularly practical.
This course is practical to know the different GIS tools and its applications to the management of water resources. No prior knowledge of GIS is required and is based on free software programs such as QGIS. This course is for begginer level.
Objectives
The course provides the student with a broad overview of the GIS tools for the study and evaluation of water resources. At the end of the course, the student will have the abilities to:
Know the open source GIS software environment.
Use specialized plugins for spatial analysis.
Represent spatial information in a thematic map.
Perform spatial interpolations and contour lines.
Use satellite images in hydrological studies.
Determine watersheds and their study parameters.

Final exam
Trainer
Saul Montoya M.Sc.
Hydrogeologist - Numerical Modeler
Mr. Montoya is a Civil Engineer graduated from the Catholic University in Lima with postgraduate studies in Management and Engineering of Water Resources (WAREM Program) from Stuttgart University – Germany with mention in Groundwater Engineering and Hydroinformatics. Mr Montoya has a strong analytical capacity for the interpretation, conceptualization and modeling of the surface and underground water cycle and their interaction.
He is in charge of numerical modeling for contaminant transport and remediation systems of contaminated sites. Inside his hydrological and hydrogeological investigations Mr. Montoya has developed a holistic comprehension of the water cycle, understanding and quantifying the main hydrological dynamic process of precipitation, runoff, evaporation and recharge to the groundwater system.
Over the last 9 years Saul has developed 2 websites for knowledge sharing in water resources: www.gidahatari.com (Spanish) and www.hatarilabs.com (English) that have become relevant due to its applied tutorials on groundwater modeling, spatial analysis and computational fluid mechanics.
