Analysis Of Water Temperature Of Laguna Lake Using EFDC Model

Laguna Lake is one of the widely used fresh water source in Metropolitan Manila. Numerous studies have been conducted for the water quality monitoring of the lake. Large amounts of pollutants are continuously received by the lake from domestic, industrial and others sources. The physical appearance of the lake alone needs attention. Physical characteristics of water include depth, flow velocity, flow rate, temperature, turbidity and transparency is very important. The lake’s water temperature not so much given attention but affects most of the chemical and biological characteristics of water, is given focus in this study. Hydrodynamic characteristics of the lake was considered in coming up with a graphical illustration of the temperature of the Laguna Lake using the Environmental Fluid Dynamics Code (EFDC). Laguna Lake is thermally unstratified with its average depth of 3.21 and mean temperature range from 25 oC to 29 oC. The EFDC model used in this study could be further used to model hydrodynamic transport and be linked with Water Quality Analysis Simulation Program (WASP).
