Abstract A thorough understanding of mountain hydrological processes and a careful assessment the characteristics coastal watersheds are essential for managing floods effectively. This work uses RS GIS approaches to analyze hydro-morphometric aspects in Swarna watershed. Gaining important insights into flood zone through integration innovative techniques is addressing challenges posed by climate change management water resources. Finding highest priority sub-watersheds based on morphometric traits, potential indicators, land use/land cover (LULC) analysis main goal current study. all-inclusive approach prioritizes classifies detected considering thirteen different characteristics, such as linear, areal, relief measurements. Further, improve ranking process, study also incorporates nine LULC features two indicators potential. Following these extensive evaluations, three groupings significance—high, moderate, low—have been established sub-watersheds. Within high-priority sub-watersheds, SW5 SW6 designated low risk high groundwater recharge, while SW1 SW2 high-risk zones recharge areas. These developments present significant opportunities decision-makers, providing them with strong foundation formulating implementing efficient watershed plans. Interdisciplinary play critical role properly integrating surface harvesting Techniques including artificial structures, check dams, rainwater systems merged smoothly conventional protection strategies. The long-term welfare communities secured strategies, which not only reduce flooding but supply ecosystem sustainability.

Intense climate change and rapid urbanization have increased the risk of urban flooding, seriously affecting economic social stability. Enhancing flood resilience (UFR) has required a new solution to cope with disasters. In this study, taking Yingtan city as an example, system indicators for evaluating UFR was constructed, 17 representative indicators, comprising three subsystems: socio-economic, ecological, infrastructural. A hybrid model combining Fuzzy Analytic Hierarchy Process (FAHP), Entropy Weight Method (EWM), Technique Order Preference by Similarity Ideal Solution (TOPSIS) applied, develop index-based measurement compare evaluate UFR, Gray Relational Analysis (GRA) used discover main factors UFR. addition, natural discontinuous method innovatively divide grade interval into levels, evaluated based on TOPSIS method. The results showed that (1) From 2010 2022, in City 80.69%, were highly correlated infrastructure development; however, ecological subsystem fluctuating downward trend because influence surface area lakes rivers; (2) grades from Level III (2010 2016) IV (2022), local financial expenditures age structure population being currently limiting development study provides theoretical basis construction indicator assessing proposes practical improvement directions
