Steady and Spatiotemporal Monitoring of Water Quality Feeding Area Southwest of Great Casablanca, Morocco

Fatine Akoh, Mohamed Tahiri, Salah Souabi

Abstract :

In Morocco, where the semi–arid climate is dominant, the supply of industrial and drinking water is provided primarily by surface water. Morocco has currently 118 multi–purpose dams. If the construction of these works was a necessity to ensure the water essential to our country in all seasons, it is impartial to control and protect the quality of running water.

– Most dam reservoir used are threatened by eutrophication due to increased terrigenous and anthropogenic pollutants, coming from an over–fertilization of water by phosphorus and nitrogen nutrients and accelerated by the uncontrolled development of microalgae aging. It is also noted that the daily practices of citizens concerning all human activities (agriculture, agro–industries, hydropower, etc.), have significantly contributed to the deterioration of water quality despite its treatment in several plants. Therefore, the treated water provides a legacy of bitter tastes and by the consumer.

– The present work exhibits result of water quality watershed Oum Erbia used to supply drinking water to the whole terraced area connecting the city of Khenifra to the one of Azemmour. The area south west of Great Casablanca (metropolis of the kingdom with about 4 million inhabitants) supplied 50% of its water needs by sourcing Dam Sidi Said Maachou located, last anchor points of the watershed before the spill in the Atlantic Ocean.

– The results were performed in a spatiotemporal scale and helped to establish a history of monitoring water quality during the 2009–2011 cycles; the study also presents the development of quality according to the seasonal rhythmicity and rainfall. It also gives an overview of the watershed stewardship concept.
