摘要

Anthropogenic land use and land cover (LULC) alterations are making urban waterbodies more susceptible to pollution risks from population growth, urbanization, industrial zones, and agricultural activities. This study employs the WRASTIC-HI framework to provide a comprehensive vulnerability assessment of Hataikheda Lake, a significant but understudied urban lake in Bhopal, India. By integrating 20 years of LULC change with expert scoring, field observations, and geo-spatial analysis, the methodology provides a scalable, affordable solution that is appropriate for situations with scarce data. Catchment-level LULC data demonstrated rapid, unmonitored, and unregulated development between 2004 and 2023, which increased pollution pressures. The calculated vulnerability index score for Hataikheda Lake was 69, indicating a high pollution susceptibility, using WRASTIC-HI, which incorporates important factors like wastewater discharge, recreational activities, agriculture, watershed size, transportation, industrial impacts, vegetation cover, and hazard indices. This work presents the first integrated assessment of Hataikheda Lake, demonstrating the pragmatic application of the methodology as a rapid screening tool for urban lake management. The findings offer crucial information that planners and legislators may use to prioritize actions and advance sustainable watershed management amidst continuous development.
