[Termes IGN] risque naturelRésumé : (Auteur) During the flood in 1997, situation in Moravia was studied from the quickest available satellite data - from the Canadian satellite RADARSAT Standard Mode with 30 meters resolution. These images which form an archive record of an immediate real state, were processed to evaluate the flood situation. The northern part of Moravia was imaged twice. The first image showed the flood peak and the second one the end of flood. The southern part of Moravia was imaged three times - the peak of flood, the end of flood and one more image shortly before the end of flood. Black and white radar images show easily distinguished water bodies. Radar images are useful for interpretation of water, forest, urban areas, agricultural areas as different units, however also for smooth surface versus rough surface, or dry surface versus surfaces with higher moisture. To study deeply flood impacts in the inundation region optical data were used. Two types of scanner data were combined with radar images - Thematic Mapper with 30 meters resolution from the second half of August 1997, two SPOT multispectral images from spring 1997 and one SPOT with 20 meters resolution multispectral image from August 1997. The situation before flood was on two images - two SPOT XLS, after on two images - Thematic Mapper and SPOT. Satellite data were also applied for up-dating water management maps - for accurate localisation of rivers, and detecting accurate shape of water basins. Combination of radar and optical data was very fruitful. Radar images presented real flood situation already within two days from data order regardless bad atmospheric conditions. Optical data which are unlike RADARSAT data archived, were implemented later for creating land use maps as an input into the model of erosion susceptibility. None of them were from the flood because of the weather.

[Termes IGN] Nil (delta du)Résumé : (Auteur) The coastal district between Baltiem and Gamasa towns represents the only remaining desert area in the northern pan of the Nile Delta. This area covers about 450 km and is occupied by various types of landforms including : beach, sandy plain, sand dune, wedand, sabkha, and evaporite crusts. The development plan of this region is facing a number of constrains which affect negatively the sustainability of development activities in this area. These constrains include : coastal erosion and accretion, sea level rise, and sand dune encroachment. The negative impact of these phenomena has been studied, in detail, using the multi-temporal analysis of remote sensing data as well as field and laboratory investigations. Monitoring changes in landuse-landcover has also been carried out using unsupervised classification of Landsat TM and SPOT images in years 1990 and 1995 respectively.

[Termes IGN] système d'information géographiqueRésumé : (Auteur) The conditions of an unexpected arrival of a flood depend directly on the hydrological behaviour of a watershed. As a Consequence, the study of flooding fields involve the knowledge of certain meteorological and physiographic characteristic of the zone of study. The work shows the contribution of Remote Sensing, a Digital Terrain Model (DTM) hydrologically consistent and GIS in the fields of water rising, the cartography of fields and their integration in a coherent set. Each time, an important rain falls on a given region of the country, we expect floods. To apprehend these floods, it is important to understand the water cycle and its various interactions with the physical medium and to give bigger importance to the rain water draining. This attention has become obvious the (past) years with the advent of a number of rain simulation watershed models. The spatio-temporal characterisation of a watershed with a GIS with different resolutions, the suitability of a deterministic hydrologic model of a conceptual type, distributed and meshed and the height flow transformation will be traited. The visualisation of the affected zones by floods was reported on DTM. The application was made on a watershed of 60 km of “Oued El Moligoun” which is situated on the upwards the city of Arzew (ALGERIA).
