- Abstract:
- The imminent extension of the large-scale Uda Walawe irrigation scheme in
the South of Sri Lanka will have serious ecological effects on a coastal
lagoon called Karagan Lewaya, which is an important bird habitat. With the
objective of predicting the impacts on its hydrology, a spreadsheet water
balance model of the lagoon was developed and combined with an adapted
existing runoff model of the catchment area. A previously established
hydrometric monitoring network was extended in order to collect data for
the development and improvement of the models and to be able to monitor
future changes. Additional information was obtained from topographical
maps and remote sensing images. Simulation results show that drainage flows
will lead to a rise of water level and decrease of salinity in the lagoon.
