AbstractWatershed management for water resources requires the accurate measurement of indicative parameters for a good knowledge of water cycle compartments. Some process conditioning water transfers in the environment such as: rainfall, runoff, infiltration, deep percolation, evaporation, water up-take and transpiration by plants, should be quantified for a better watershed management. This paper shows an infiltration assessment with Triple Ring Infiltration at Multiple Suctions method, realized in the upper watershed of Nazas river that is the main source of water supply for agriculture in a great irrigated area of northern Mexico. This watershed is submitted to strong productive activities for forestry and agriculture production that cause disturbs on the ways of water cycle with important hydrological impacts. The results show that soil surface conditions lead the infiltration process and they can be linked to land use changes of productive systems. Good practices for soil and water conservation are proposed for a better management in order to keep the good hydrological services of this watershed.
