Overview

Investigates satellite-derived precipitation effects on runoff in semi-arid regions, suggesting new management strategies.

Key Points

  • To evaluate the capability of satellite precipitation products in assessing climate change impacts on water resources in semi-arid regions.
  • Utilized the PERSIANN-CDR satellite-derived precipitation product for assessment.
  • Conducted comparative analysis against observed precipitation data.
  • Simulated runoff using GR2M and Thornthwaite hydrological models under various climate scenarios.
  • PERSIANN-CDR generally underestimates peak precipitation and total rainfall compared to in situ observations.
  • Projected temperature increases of 2–3 °C and significant declines in precipitation (−30% to −80%) under different RCP scenarios.
  • Projected decreases in runoff by 50–90%, highlighting sensitivity during low-flow periods.
