Short Summary

This study quantifies evaporation losses from the Kailana and Takhatsagar reservoirs in Jodhpur, India, developing an evaporation estimation model that incorporates depth-area relationships. It reveals significant seasonal variability in evaporation, ranging from 2.73 mm day⁻¹ in winter to 13.76 mm day⁻¹ in summer, and estimates a combined average loss of 9,733.6 m³ day⁻¹ at full supply level, providing a practical tool for water management in arid environments.

Objective

• To quantify evaporation losses from the Kailana and Takhatsagar reservoirs and evaluate their implications for water management in an arid environment.

Study Configuration

• Spatial Scale: Kailana and Takhatsagar reservoirs, Jodhpur, Rajasthan, India.
• Temporal Scale: Daily evaporation losses, with observed seasonal variability (winter, summer). The model supports long-term water resource planning.

Methodology and Data

• Models used: An evaporation estimation model developed using relevant meteorological parameters; depth–area relationships established for both reservoirs.
• Data sources: Relevant meteorological parameters; limited runoff from surrounding hills during rainfall events.

Main Results

• Evaporation exhibits pronounced seasonal variability, ranging from a minimum of 2.73 mm day⁻¹ in winter to a maximum of 13.76 mm day⁻¹ during summer.
• At full supply level, the combined average evaporation loss from both reservoirs is approximately 9,733.6 m³ day⁻¹.
• Recent studies indicate that evaporation from Indian reservoirs has increased by approximately 5.9% per decade between 1985 and 2018.

Contributions

• Development of a practical evaporation estimation model for key water supply reservoirs in an arid region.
• Quantification of seasonal evaporation losses for Kailana and Takhatsagar reservoirs, crucial for local water budgeting.
• Provision of a tool to support long-term water resource planning and management in water-stressed arid environments.
