Short Summary

This study investigates the impact of climate change on water resources in a semi-arid region using a coupled hydrological model. The results show that climate change will lead to a significant decrease in water availability by 2050.

Objective

To assess the effects of climate change on water resources in a semi-arid region and to identify the most vulnerable areas.

Study Configuration

• Spatial Scale: A 10 km x 10 km grid covering an area of approximately 100,000 km².
• Temporal Scale: Daily time steps from 1970 to 2050.

Methodology and Data

• Models used: The Variable Infiltration Capacity (VIC) model was used to simulate the hydrological processes.
• Data sources: Gridded precipitation data from the PRISM dataset, temperature data from the NCEP reanalysis, and soil moisture data from the USGS.

Main Results

The results show that climate change will lead to a 20% decrease in water availability by 2050. The most vulnerable areas are identified as the regions with high population density and agricultural activity.

Contributions

This study provides new insights into the impact of climate change on water resources in semi-arid regions, which is essential for developing effective adaptation strategies.
