Abstract: Efficient water management is critical for sustaining agriculture, especially in regions that heavily rely on natural water sources for irrigation. The Guptamani Watershed in West Bengal, India, has been modeled using MIKE SHE to assess groundwater recharge and evapotranspiration dynamics. This study investigates how different hydrological processes, such as surface runoff, evapotranspiration, and groundwater recharge, interact in a watershed facing varying seasonal rainfall patterns. The MIKE SHE model has provided valuable insights into the water balance of the region, showing that a significant portion of rainfall is lost to evapotranspiration, while surface runoff and groundwater recharge account for smaller proportions. The study underscores the importance of groundwater recharge in sustaining agricultural productivity during dry periods, while highlighting the need for targeted water management strategies to optimize soil moisture retention, particularly in upstream areas. These findings provide a basis for sustainable water resource management in the face of climate variability and water scarcity challenges.
