摘要：

Kandy City is recognised by UNESCO as a world heritage city because of its history and cultural treasures. In the centre of the city is Kandy Lake, a 0.25 km2 man-made waterbody. Urbanisation and consequent inadequate waste management facilities have resulted in deterioration of the lake's water quality. This study investigates issues related to water discharges into the lake and flow patterns therein. The hydraulic study utilises Delft3D software as the computational tool. Flow 'dead-zones' which can be locations of lower water quality and accumulation of debris are identified using the model. A number of possible mitigation solutions are discussed in the paper. These include diversion of existing drainage channels to other less sensitive locations in the lake.
