AB  - Riverine floodplains are highly dynamic and the most vulnerable space on Earth 
      particularly in flat alluvial plains of major river systems. Suitable site 
      selection for sustainable human settlements in active floodplain areas is a 
      critical task for decision-makers in terms of quality of lithology, ecologically 
      fragile landmass, climate-induced hazards, immense population pressure, and 
      environmental conservation issues. This research introduces a methodology for 
      settlement suitability zone (SSZ) that employs GIS-based multi-criteria 
      decision-making (MCDM) techniques. As a case study, an altered hydrological 
      regime of the lower Ganga riparian zone was chosen to identify the SSZ as these 
      areas are the most susceptible to riverine hazards. Twelve significant variables 
      reflecting on topography, climate, landscape, and environment have been selected 
      in the multi-criteria evaluation platform. The CRiteria Importance Through 
      Intercriteria Correlation (CRITIC) method is adopted to specify the weights of 
      the criteria and utilize an inverse distance-weighted (IDW) spatial interpolation 
      technique to generate an SSZ map in a GIS environment. The study zone is 
      spatially quantified into five categories, from unsuitable to high-suitable with 
      a natural breaks (Jenks) classification method. Subsequently, the final results 
      are validated through a receiver operating characteristics (ROC) curve using 
      randomly selected 56 hazard-exposed location points. The outcome revealed that 
      8.45% of the riparian area falls under unsuitable, 21.87% under low-suitable, and 
      33.27% under moderate-suitable for locating human settlements. The generally 
      suitable and high-suitable categories account for 36.40% of the total study zone. 
      A spatial sensitivity analysis is also applied to gauge the influence of each 
      parameter on the MCDM outcomes. The SSZ mapping results from this study can help 
      local authorities to plan for sustainable settlement development in 
      environmentally fragile areas.
