This study focuses on identifying GW-SW interaction locations in a tropical lake - Vellayani Lake (VL), Southwest India, utilizing stable water isotopes (s18O, sD) and chloride mass balance approach. The northern region was identified as critical groundwater discharge “hotspot” with pronounced (2.14×106 3.82×106 m³/yr), prompting targeted management interventions. reaffirms the role of inflow sustaining lake’s balance. Additionally, application machine learning (ML) techniques refined classification Lacustrine Groundwater Discharge (LGD) non-LGD sites while predictive modeling Sensitivity Indices enhanced understanding prominent factors influencing volume. K-means clustering Random Forest (RF) classification, achieved high accuracy (90%) kappa value 0.8 distinguishing non-discharge sites. Predictive sensitivity analysis revealed precipitation most influential factor, ±20% change causing 16.69% variation exhibited index 0.5320, further emphasizing its maintaining hydrological integrated approach provided valuable insights into nearshore recharge facilitates identification suitable areas for structures. For practitioners policymakers, this offers robust framework zones, prioritizing areas, designing sustainable strategies, especially data-scarce regions, paving way improved resource similar environments.
