Short Summary

This study assesses the water supply, demand, and balance in the Cauto River Basin using coupled SWAT and WEAP models under baseline and projected future conditions. It projects a 2.5% decrease in annual flow and a 16.6% surge in water demand by 2050, leading to a 52% increase in the water deficit.

Objective

• To provide a comprehensive assessment of the water supply, demand, and balance within the Cauto River Basin, considering baseline and projected socio-economic and climatic conditions by coupling SWAT and WEAP models.

Study Configuration

• Spatial Scale: Cauto River Basin (CRB), Cuba.
• Temporal Scale: Baseline scenario and a future scenario (2050).

Methodology and Data

• Models used: SWAT (Soil and Water Assessment Tool) and WEAP (Water Evaluation and Planning) models.
• Data sources: Not explicitly detailed, but includes baseline and projected socio-economic and climatic conditions.

Main Results

• The annual flow in the Cauto River Basin is projected to slightly decrease by 2.5%, with a higher reduction in the rainy season (3.1%) compared to the dry season (1.3%).
• The total water demand in the baseline scenario is approximately 1.194 x 10^9 m^3, with agriculture accounting for 96% of this demand, and rice crops requiring nearly half.
• For the future scenario of 2050, total water demand is projected to surge by 16.6% to 1.394 x 10^9 m^3, primarily driven by climate change and agricultural expansion.
• Domestic water use is projected to decrease by 10% due to anticipated population reduction.
• The water deficit is projected to increase by 52% from 1.724 x 10^8 m^3 to 2.627 x 10^8 m^3 in the future, resulting from rising water demand and declining water supply.

Contributions

• Provides a comprehensive and quantitative assessment of water supply, demand, and balance for the Cauto River Basin, a critical agricultural region in Cuba.
• Demonstrates the efficacy of integrating a hydrological model (SWAT) with a water allocation model (WEAP) for robust water resources management.
• Quantifies future water deficits under projected climate change and socio-economic changes, offering crucial insights for regional water management strategies.
