             abstract = "The plunge point locates the main point of mixing between river 
                         and the epilimnion reservoir water. The plunge point monitoring is 
                         essential to understand how it will be the behavior of density 
                         currents and its implications for reservoir. The applicability of 
                         satellite imagery products from different sensors (Landsat TM band 
                         6 thermal signatures and visible channel) for characterization of 
                         the river-reservoir transition zone is presented in this study. We 
                         demonstrate the feasibility of the Landsat TM band imagery to 
                         discern the subsurface river plumes and the plunge point. The 
                         spatial variability of the plunge point evident in the hydrologic 
                         data illustrates the advantages of synoptic satellite measurements 
                         over in situ point measurements alone to detect the 
                         river-reservoir transition zone. It is indicated that the river 
                         flowing as underflow contributes to the thermal stability of the 
                         water column during wet season (summer-autumn). During the dry 
                         season, when the river-reservoir water temperature differences 
                         vanish and the river circulation is characterized by 
                         interflow-overflow, the river water inserts into the reservoir 
                         upper layers, affecting water quality. The results indicate good 
                         agreement between hydrologic and satellite data and that the 
                         jointly use of thermal and visible channel, operational monitoring 
                         of plunge point is feasible. The deduced information about the 
                         density current from this product could potentially be assimilated 
                         for numerical modeling and hence be of significant interest for 
                         environmental and climatological research.",
