Abstract

The objective of the present study is to present the parameters of the hydrological assessment of a steppe area from the data of remote sensing. ¶Adopted methodology rests on the cartography of the various parameters of the hydrous and energy balance on one year scale. ¶Several methods are used. ¶Thus, for cartography of precipitations, one uses in a combined way the relief, the distance of the sea and the exposure. ¶The second method is used for the cartography of the streaming on an each pixel scale. ¶This method utilizes a matrix which calls upon the information contained in space variability and information resulting from the first method. ¶The combination of information of precipitation and the streaming allow the development of the chart of infiltration. ¶The third method consists with the estimate of the evapotranspiration on broad scale. ¶This last method uses images AVHRR and the model of assessment of energy Surface Energy Balance Algorithm for Land (SEBAL). ¶The quality and the space precision of these cartographies using imagery NOAA AVHRR open a broad hydrological field of application and can be extended for the exploration of all the Algerian steppe area.¶
