Abstract: Anthropogenic activities have altered natural runoff regimes and segmented channel-plain interconnections. The disconnection of the channels from their natural plains, caused by agricultural activities and soil paving, has interrupted natural water outlets and reduced infiltration. A case study of such case is the Grijalva Basin, in Mexico, where since mid-20th century there has been a large modification of the land use to convert rainforest to grassland and cropland, the land use change is active up to now. An analysis based on data obtained from gauging and climatological stations shows here that the Annual Runoff Coefficient in a large part of the analyzed area developed an increasing trend in the period the information is available, the earliest records are from the 1950s.
