The standard study aims at giving the hydrobiological situation of one river at the time of the study. That situation concerns the morphodynamic, physical, chemical, phytozoological characteristics, the population of fishes and their relationships, with the anterior situation estimate and the actual situation diagnostic. It can give rise to ecological evolution hypotheses established according to the modifications of the aquatic environment. In the must frequent cases, it is followed by some instructions or propositions for the best and wished hydrobiological management of the river.
