Abstract

Many marsh areas in Southern Spain were dewatered during the 1950's for agricultural purposes. These actions were not successful due to the high salinity trend exhibited in such soils, especially notable during the long dry summers in these locations. Recently, many attempts to restore the marshes have been made to try to return the original flooding cycles to the dewatered areas, and promote the development of spontaneous vegetation suitable to salty environments. This work deals with the monitoring of the increase of the flooding area in the San Pedro River marshes (Cádiz) in Spain after the demolition of a dam near the mouth, from the analysis of Landsat TM images with a linear mixture spectral model. Three different components (vegetation, dry soil and wet soil) were quantified in the area over the two years following the destruction of the dam and the increase in tidal entry to the marsh and compared to the results from a previous date. The results were calibrated with field data measured directly on the terrain surface. The model used was capable of discriminating such components with satisfactory accuracy, providing data on the evolution of the flooding area throughout the year and the increase in vegetation distribution one year after the dam break. Differences in the tidal advance along tidal creeks in the main reach of the river before and after the demolition were successfully identified. The impact of the dam action on the development of vegetation was also quantified; the results showed the potential to restore this degraded marsh land.
