Dynamics of the salt wedge in the lower Bolas river basin

In addition to being an essential element for life and part of the functioning of ecosystems, water is an indispensable and irreplaceable input for a wide range of social, biological and economic activities. Salinization or saline intrusion is a process that is affecting the quality of surface and groundwater in the main regions in the south of the country, given the intrusion of salty seawater into the water table and into the surface freshwater bodies due to the reduction of the natural hydraulic pressure of the rivers. The objective of the following research is to generate information on the dynamics of the salt wedge in a sector of the littoral area (lower basin) of the Bolas River. Some studies carried out on coastal aquifers in Central America mention saline intrusion as a contamination problem for water resources in the coming years.
