The model study forms part of of the UNDP/FAO "Integrated Resxource Development of the Sundarbans Reserve Forest" project. The aim of the project is the formulation of a strategy and integrated plan for the sustainable multiple use, conservation and management of the forest, wildlife and aquatic resources of the Sundarbans Reserve Forest.

Field data have been colected including cross section morphology, water levels, flow velocities and salinity samples covering the entire Sundarbans Reservfe Forest area. The difficult terrain and remoteness of the area dictated the use of advanced data acquisition methods, including self-recording submerged pressure and conductivity sensors and satellite-based postioning systems.

Existing hydrodynamic and salinity models have been refined based on a detailed river network representation. The models describe seasonal variations in the duration and frequencies of mangrove inundation, salinity distribution and sedimentation/erosion potential. The study also quantified impact of cyclone events, floods and reduced freshwater inflows.
