ABSTRACT:
Leveraging the effort of an existing hyperresolution Regional Climate Model (RCM) output and a state-of-art hydrological model (Coupled Routing of Excessive STorage, CREST), this study examines the hydrological condition changes in 2075-2079 compared to its semi-current state in 2015-2019 in Arequipa region under the Shared Socioeconomic Pathways 5-8.5 (SSP5-8.5) scenarios. The CREST-VEC model is used to simulate the rivers within the Arequipa region in Peru. The region would face a 19.8% runoff reduction, 83% - 86% averaged streamflow reduction, and 37.8 days of wet season duration reduction. The Rio Chili would experience complete “no water” events in 2078 and 2079, and all the 1st order stream reaches would be dry more than 50% of the time between 2075 and 2079 compared to less than 40% of the time in 2015-2019. However, the flood risk would not decrease in the future, with the City of Arequipa expected to face at least one flood event that is more severe than its 2017 and 2019 floods, and Rio Colca would have many more flood events in the future.
