Potentials of landsat tm image to investigate the nearshore and offshore bars along the Arab’s gulf shore zone, western of Alexandria, Egypt

Abstract EN

Remote sensing has been shown as the most efficient tool for coastal management.

A major problem for mapping coastal area especially in developing countries is that it consume time indeed it very expensive.

The present study aims to provide a simple statistical regression method to drive bathymetric map for the Arab’s Gulf shore zone, Western of Alex., Egypt, using the reflectance data derived from Landsat thematic mapper.

The method was successfully tested achieved between measured and calculated depths points, and provides a simple and good facility for Geomorphologists to rich and improves their both qualitative and quantitative results in the study area, and it is very important to note that, the successful application of the suggested logarithm needs to consider carefully differences in water attenuation coefficient values due to water column characteristics.

Applying the suggested logarithm may not be appropriate for other scenes because the differences in water attenuation coefficient values due to water column characteristics.
