Current and temperature structure of Rihand Lake

Abstract

The environmental parameters such as wind, water and air temperatures, and currents were measured in Rihand Lake, Madhya Pradesh, India during the hotest months, May-June of 1983. Rihand is an artificial lake having an area of 300 km super(2) and situated in tropical arid zone. The winds are normally weak but highly variable. High surface temperature gradients are established near the shore. The discharge of warm water from a nearly super thermal power station does not appear to have major influence on the vertical as well as horizontal temperature structure of the lake. The surface currents are highly variable due to wind but mostly follow the depth contours. The bottom waters of the deepest area seem to be stagnant as seen from the current and temperature structure
