Sustainability requires that once reservoirs are built, they should be managed as environmentally friendly as possible. If the management policy does not achieve efficiency, there might be a man-made disaster occurred. There is a need for establishing a national strategy for developing hydrological forecasting techniques. In this study, hydrological models MARINE and SWAT were established for the Ban-Chat reservoir basin by testing performance in simulating hourly inflow during flood season for short term forecast and daily inflow for long term management respectively. Both models are set up using the same available database but they differ in terms of spatial discretization, infiltration and water redistribution representation and river flow transfer. Overall, it is argued that MAR... |
In this study, the solidification process of a compound droplet is numerically simulated by an axisymmetric front-tracking/finite difference technique. The compound droplet placed on a cold flat surface in a gas environment consists of an inner gas core surrounded by a concentric shell phase-change liquid that forms an outer droplet. The initial droplet shape assumed as a spherical cap is therefore determined by two wetting angles known as the inner wetting angle (?0i for the inner core) and the outer wetting angle (?0o for the outer droplet). During the solidification process, there is the presence of two three-junction points where a prescribed growth angle ? is specified. We analyze the solidification process undergoing the influence of the geometrical aspects of the compound dro... |
