Process of creation of natural temporary pools in Morocco, and physicochemical characteristics of some pools of them

In the Mediterranean region, temporary pools are accumulations often formed annually, by water inputs of precipitation. The biotopes of these pools can be of artificial origin, by creation voluntarily or involuntarily of the Man, or natural. Moreover, whatever the evolution of the characteristics of the waters of the temporary pools does not differ in very remarkable ways, the geologic nature of the parent rock and the pedagogy of the sediment influence these characteristics. Thus, the present work, by an observation and an analysis of the geological context and biotope of the biotopes of the temporary pools in the richest geographical zones of temporary natural pools. The results showed that in Morocco, different types of natural pond formation process differ according to the geological nature of the support. The latter may be clayey, sandy, calcareous or dolomitic, basaltic or granitic. However, the tendency of these processes is effected by water erosion, erosion, chemical, and the result is the same: progressive enrichment of the biotope by the clay. From the point of view of physico-chemical characterization of temporary pools, the results showed the evaluation of physicochemical parameters characterizing the water showed that, in the region studied, the values ​​of these parameters are influenced by the factor "season". In fact, the majority of the parameters showed low values ​​at the beginning of impoundment of the pond and high values ​​towards the end of this impoundment. Similarly, during the flooded phase of the pond, the evolution of the values ​​of certain parameters such as the pH, the rate of oxygenation of the water, the rate of the organic matter is influenced by the quantity of the excrements of the pond. livestock using the pond as a source of food or watering place.
