ABSTRACT

Background: The rainfall records are the base of all hydrological studies (statistical climatic, water planning and resource management, delimitation of the floodplains). However, the precision on the knowledge of precipitations on a given surface requires much network observation and distributed well. The importance of this network often results from a compromise between the desired precision and the constraints of management, budget amongst other things. Methods: The methodology of rationalization suggested in the watershed of Sebou, in northern Morocco, is primarily based on the application of the statistical approaches in order to evaluate the relevance of the stations of a network from statistical point of view and to remove the station if this proves to be inevitable. Results: The network of observations on the Sebou watershed level is characterized by a density of the pluviometric stations satisfactory. It comprises more than 164 stations for 250 km ². However, the network of observations in the surface of study is denser in plain than in mountain: altitudes higher than 2100 m. For the evaluation of requirements in data, it is important to use the geostatistic techniques such as the clustring and the krigeage and this in order to characterize the distribution of rain and to work out a statistical methodology and to acquire programs of the approaches studied to help in the search of redundancies of hydrological information. Conclusion: The results from the 54 studied stations are favorable, with some small exceptions, for a cutting of the Sebou watershed in 4 great homogeneous zones which make it possible to describe in a relevant way the variability of annual precipitations in the basin.
