IAHR, founded in 1935, is a worldwide independent member-based organisation of engineers and water specialists working in fields related to the hydro-environmental sciences and their practical application. Activities range from river and maritime hydraulics to water resources development and eco-hydraulics, through to ice engineering, hydroinformatics, and hydraulic machinery.

ABSTRACT
Damming of Punggol and Serangoon Reservoirs, together with the development of Marina Reservoir, has increased
Singapore water bearing reservoir catchment area from half to two thirds of Singapore’s land surface. Rain water
collected from roads, pavements, roof tops and other surfaces is channeled to the reservoirs from respective catchments
through a comprehensive network of drains, canals and storm water collection ponds. These reservoirs also receive
pollutants flushed from large urbanized catchment area. To develop a waterfront town and improve the recreation
facilities in Punggol, the Punggol Waterway has been developed by connecting the two reservoirs. With main objective
to provide drinking water supply, a monitoring framework is needed to meet the water quality regulations. In this context,
a study is being carried out to predict water quality in Punggol and Serangoon Reservoirs and Waterway system
(PSR&W). Present study focuses on work carried out for validation of hydrodynamic models in terms of representation
of temperature. Application of hydraulic-3D hydrodynamic coupling, heat flux model and turbulence closure model is
applied to capture a weakly-dynamic system of the reservoirs. Spatial and temporal distributions comparisons between
simulated and observed results suggest that the output of 3D hydrodynamic can be used as inputs for subsequent water
quality modelling.
