The purpose of this study is to build a tool to separate the effect of climate variability and anthropogenic influences on hydrology and suspended sediments. A modeling method combining in situ and climatic satellite data was used to analyze the discharge (Q) and suspended sediment concentration (SSC) at a daily time scale from 2000 to 2014. Scenarios of natural and actual conditions were implemented to quantify the impacts of climate variability and dams. The modeling gained satisfactory simulation results of water regime and SSC compared to the observations. Under natural conditions, the Q and SSC show decreasing tendencies, and climate variability is the main influence factor reducing the Q. Under actual conditions, SSC is mainly reduced by dams. At the outlet, annual mean Q got reduced by 13% (9% by climate and 4% by dams), and annual mean SSC got reduced to 89% (13% due to climate and 76% due to dams) of that under natural conditions. The climate tendencies are mainly explained by a decrease of 9% on precipitation and 5% on evapotranspiration, which results in a 13% decrease of available water for the whole basin. specialized Red River SWAT model hydrology suspended sediment dam impacts climate VIET NAM 062 020 021 11 5 art. 958 [26 p.] 2019 2073-4441 https://www.documentation.ird.fr/hor/fdi:010076164 10.3390/w11050958 2073-4441 [F B010076164] https://www.documentation.ird.fr/hor/fdi:010076164 https://horizon.documentation.ird.fr/exl-doc/pleins_textes/divers19-07/010076164.pdf IRD - Base Horizon / Pleins textes 2019-08-05 2025-02-24 fdi:010076164 fre
