In Jordan, water resources are scarce and decreasing, and groundwater is considered the major water resource. The Azraq is one of the largest groundwater basins in Jordan, and it is currently facing an over-extraction problem. This study attempts to assess and map groundwater resources in the Azraq Basin using ARCVIEW GIS software. The relationship between land topography and depth-to-water surface was found to be statistically significant, while there was no significant association between land topography and groundwater level. Two essential thematic layers were created-depth to groundwater and groundwater level and the slope of groundwater level was mapped. The majority of the study area has a slope of less than four degrees with smaller scattered areas were the slope could rise up to 8,6 degrees. The results indicate that, due to the nature of the data involved and the analysis required, GIS could facilitate the necessary spatial digital analysis. Subsequently, its outcomes can be used for future groundwater planning and monitoring.

[Termes IGN] utilisation du solRésumé : (Auteur) One important aspect in the management of the environment and its resources is establishing the spatial extent and the dynamics of changes in land cover and land use over time. This paper proposes a methodology for monitoring land cover change in coastal zones, specifically coastal mangrove wetlands. The approach was inspired by the availability of aerial photographs at several epochs and their high spatial resolution and geometric stability. The topographic features of coastal zones justify relaxing the rigorous and complicated procedure of photogrammetric orientation, while still achieving an adequate reliability and accuracy. The methodology developed in this paper is followed by a case study evaluating the validity and applicability of this technique in assessing changes in coastal mangrove forests.

[Termes IGN] laisseRésumé : (Auteur) Determination of the ordinary high water line (OHWL) has been and continues to be an important issue for the State of Florida and elsewhere. The OHWL defines the separation of sovereignty lands of the State and private ownership on non-tidal water bodies. We used imagery from multiple sources to determine if (1) the water's edge can be detected around the lake margins and (2) vegetation community shifts can be reliably detected and correlated with OHWL. It was determined that in areas where water is known to be under vegetation canopy or in heavily vegetated marsh there were no distinct indicators of the OHWL on any of the remote sensing images used. This is because overhanging vegetation and emergent macrophytes both obscure the water's edge. We also found that vegetation types varied widely and none appeared to be precise indicators of the OHWL Most of the plant species in the vicinity of the known location of the OHWL were not classified in any one wetland designation and many were found both in wetland and upland areas and, therefore, provided no distinct characteristics that could be consistently identified or mapped in ArcView using remote sensing images.
