  abstract = {{T}he variation of water quality in 24 small reservoirs of semiarid {T}unisia was studied in relation to catchment and hydrological context duing two successive and contrasting hydrological years. {M}easured salinities generally satisfied the various uses. {T}hree geochemical groups were identified based on the water quality during the inflow period. {C}alcium sulphate water types charachterize reservoirs located in {Z}eroud and {M}erguellil catchments. {T}hey have the greatest dissolved salt contents and an increase of salinity by evaporation may limit their suitability for irrigation. {C}alcium bicarbonate dominated waters, especially observed in the {M}edjerda subcatchments, are far more diluted and present less constraints. {T}wo reservoirs located in {C}ap {B}on are made conspicuous by sodium chloride dominated waters with a low ionic content. {T}he salinity of this kind of water increases more quickly with evaporation and can then impose constraints for irrigation use.
