Na Argélia, a erosão do solo nas bacias hidrográficas constitui um problema grave. Com efeito, a degradação do meio ambiente tem consequências muito nefastas para a produtividade das terras e para os volumes de água mobilizados nas barragens e reservatórios, sem esquecer o impacto na qualidade das águas. Apesar dos esforços de combate à erosão, tais como a reflorestação, a recuperação florestal e a construção de valas de absorção ou de desvio, a degradação da vegetação e dos solos continua; a bacia hidrográfica de Oued Charef não escapa à regra. Esta bacia, que faz parte da grande bacia hidrográfica do Seybouse, tem forma triangular e estende-se por uma superfÃcie de 1 776 km .Este livro tem como objetivo estudar a estimativa quantitativa dos sedimentos com base em dados e valores sazonais obtidos junto da Agência Nacional de Recursos HÃdricos, a fim de estimar a quantidade total de sedimentos e a degradação especÃfica da bacia hidrográfica, de modo a propor as medidas necessárias para a sua proteção.
