dc.description.abstract |
There are many small islands all over the world
which face scarcity of drinking water. Recharge is an important
factor which controls the available freshwater lens. In addition
to natural recharge, artificial recharge can be used to increase
the freshwater lens volume. The objective of this study is to
identify the impact of artificial recharge in small islands. Three
islands in the Maldives were selected for this study. A model
was developed by using SUTRA (Saturated Unsaturated
TRAnsient Model) with Model Muse as graphical user interface
and calibrated until the percentage difference between
simulated and observed freshwater lens volume is less than
10%. The impact of artificial recharge was identified by
increasing the recharge rate by 5% and 10% of annual rainfall
and simulating the previously calibrated model. The freshwater
lens thickness and volume increase with artificial recharge.
With 5% of annual rainfall as artificial recharge, the freshwater
lens thickness of Dharavandhoo, Henbadhoo and
Bodufulhadhoo island increased from 5.2 m to 6.9 m, 2.6 m to
4m and 1.5 m to 2.7 m, respectively. Based on these results, it
can be concluded that artificial recharge will be a sustainable
solution to overcome the scarcity of drinking water in small
islands. |
