  abstract = {{M}any studies have been published on the use of models to assess water quality through faecal contamination levels. {H}owever, the vast majority of this work has been conducted in developed countries and similar studies from developing countries in tropical regions are lacking. {H}ere, we used the {S}eneque/{R}iverstrahler model to investigate the dynamics and seasonal distribution of total coliforms ({TC}), an indicator of faecal contamination, in the {R}ed {R}iver ({N}orthern {V}ietnam) and its upstream tributaries. {T}he results of the model showed that, in general, the overall correlations between the simulated and observed values of {TC} follow a 1:1 relationship at all examined stations. {T}hey also showed that {TC} numbers were affected by both land use in terms of human and livestock populations and by hydrology (river discharge). {W}e also developed a possible scenario based on the predicted changes in future demographics and land use in the {R}ed {R}iver system for the 2050 horizon. {I}nterestingly, the results showed only a limited increase of {TC} numbers compared with the present situation at all stations, especially in the upstream {V}u {Q}uang station and in the urban {H}a {N}oi station. {T}his is probably due to the dominance of diffuse sources of contamination relative to point sources. {T}he model is to our knowledge one of the first mechanistic models able to simulate spatial and seasonal variations of microbial contamination ({TC} numbers) in the whole drainage network of a large regional river basin covering both urban and rural areas of a developing country.},
