Evaluation of saltwater intrusion, analysis of salt distribution in groundwater, and prediction of future scenarios requires the use of numerical tools that are in constant development. The latest tool available for variable density flow developed by the USGS is the BUY package from MODFLOW6 that is implemented in Flopy and Model Muse. The combination of these tools allows creation of groundwater flow models for seawater intrusion in a short period of time, precise analysis of water balances and brine concentration and potential coupling with other tools such as PEST.

Saul Montoya M.Sc. 

Saul Montoya M.Sc. is a Hydrogeologist and 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.
