Captación de agua subterránea por drenes horizontales en pequeñas islas.

This paper evaluates different types of groundwater exploitation systems used in coastal areas and in small islands where seawater intrusión can occur. In many cases using open trenches for groundwater supply inconveniences appear because of seawater penetration associated with hurricanes. Pumping wells should not be used even shallow ones because of intrusion cones. It is also recommended to substitute open trenches by horizontal drains with control systems for levels and water quality in the collectors from where water would be pumped as if they were storage deposits. This also decreases evaporation losses, environmental drawbacks and contamination from drag of solids as well as reduces the possibilities of seawater penetration. [ABSTRACT FROM AUTHOR]
