CWR Presents : Cloud-Assisted Real-Time and Large-Scale Monitoring and Analysis for Water Quality Other events...
This talk will first discuss the thermal structure and hydrodynamics of Kranji Reservoir, a small and shallow tropical reservoir located in Singapore.

In particular, it highlights the dominant role of surface heat flux in lake heat budgets and diurnal thermal stratification. It also demonstrates the importance of tributary inflows and dam releases as a dominant component in water budget. Diurnal cycles of thermal stratification/destratification and substantial horizontal redistribution of heat were observed in Kranji Reservoir. To model the physics and water quality of Kranji Reservoir, we use the ELCOM-CAEDYM model, an integrated 3-D hydrodynamic-ecological model developed by the Centre for Water Research, University of Western Australia.

ELCOM-CAEDYM is a complex model and model calibration is often time consuming, since running on a single CPU core usually takes several hours or days to complete a simulation run. With cloud computing technologies, however, we managed to parallelize the execution of model simulations automatically on multiple computing nodes on a cloud platform and achieved significant speedup of the model simulations. We further carried out a global sensitivity analysis using Monte-Carlo method and identified the most influential CAEDYM model parameters.
