The local shoreline geomorphology and regional differences in coastal processes are fundamental in estimating erosion rates. Our results show that in the permanently cloudy tropical coastal areas of and north east Brazil, RADARSAT S7 image is particularly useful to map areas of erosion, and deposition, as well as the adjacent affected coastal land use. Coastal changes were estimated by comparing recent RADARSAT images with previous topographic maps. In north east Brazil erosion rates on fractured quaternary sediments vary from 0 to 12 meters a year, and on the more resistant sandstone erosion rates vary from 0 to 6 meters a year. In Guyana, low flat areas below sea level, erosion rates vary from 0 to 25 meters a year. In EI Nino year, these estimates are expected to increase.

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.

Monitoring of land use and crop growth conditions in Europe / G.J.A. Nieuwenhuis (01/09/1998)

Based on the classification results the meaning of a 1-km land cover database at the European scale for agricultural and environmental applications has been illustrated. In a recent study for the Space Applications Institute (SAI) of the Joint Research Centre (JRC, Ispra) the integrative use of high and low resolution satellite data and crop growth models have been studied by SC-DLO. Vegetation indices as derived from both high and low resolution satellite data were used to estimate crop parameters. Especially if the actual situation deviates considerably from the mean situation, more realistic yield figures were obtained. Evapotranspiration maps have been composed using both satellite systems. In general areal patterns as obtained with high and low resolution satellite data were in agreement with each other. This means that such images are highly relevant to detect alarming situations concerning crop water supply during the growing season. A quantitative analysis should be further elaborated, integrating satellite observations and crop growth model simulations.

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.

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).
