| Abstract: | Satellite imagery can be used to map shallow water depth using techniques which utilize only a few selected depth sounding points as input. For the present work three different models were considered for water depth estimation, which relate different parameters with the water depth. The Landsat-4 MSS data of the sounding points were used for calculation of model parameters. Goodness of fit of the above models was tested using statistical tests, which showed that the exponential relation between water body radiance and water depth gives best fit for shallow water bathymetry. Contour map of water depths over the coastal region of Andhra Pradesh near Machlipattnam have been drawn with the help of the above models using remotely sensed data of the area. |
