Abstract

Organic pollution index OPI and biological river macrophyte index BRMI were evaluated in Oued Rhiou river. During the months of April, May and June 2014, results of biological oxygen demandBOD5, ammonium, nitrite and orthophosphate were used to calculate OPI. BMRI was calculated during June 2014, a vegetation development period of helophytes, hydrophytes and algae recoveries. During the three months of April, May and June, OPI evaluation reveals that sites S2 and S3, which receive anthropogenic releases are marked by a strong level of organic pollution. Site S1, which receives no effluent is characterized by a medium level of organic pollution. During June, the BRMI index indicates a strong trophic level in both S2 and S3 sites, cons, it shows a mean trophic level in S1 site.
