CANALES, Armando G. et al. Seawat Model for Saline Intrusion in Boca Abierto, Sonora Aquifer. Tecnol. cienc. agua [online]. 2016, vol.7, n.4, pp.155-160. ISSN 2007-2422.

The "Boca Abierta" Valley's aquifer at a coastal plain has been overexploited with the consequence of some high rate of contamination by saline intrusion of Seawater. The study objective was to test a double barrier of pumping wells to control salt water intrusion in Boca Abierta Valley aquifer by applying the model Seawat. In the calibration period 1990-2012 the difference between observed chloride concentration and the model calculated value in several wells got a value of residual mean square (RMS) of 2.87%. The predictive phase a simulation period of 20 years (2012-2032), with two locations for 10 pumping wells and flow rate of 120 l/s per well, in the named " double barrier 1" kept or reached gradually chloride concentration of water from the aquifer below the permitted value.
