Abstract

The Catamayo-Chira basin is an interesting case study for investigating these geomorphic implications. The aims were: (i) to study the effect of ENSO on stream flow and sediment yields in the basin, (ii) to investigate if ENSO events affect sediment yields in the post-ENSO period and (iii) to understand which factors control the ENSO and post-ENSO basin response. The analysis indicates the increase of vegetation growth in the lower basin is not the main reason explaining considerable sediment flux decrease in post-ENSO periods. During strong ENSO events, sediment in alluvial stores in the lower part of the basin is removed due to enlarging and deepening of channels. The decrease in sediment export will last for several years until the equilibrium is re-established
