3. Hydrology, Watershed & Flood Risk

We provide comprehensive hydrological, hydraulic and flood-risk assessment services for urban development, infrastructure, industrial, irrigation and water-resource projects. Our studies integrate rainfall analysis, catchment characteristics, terrain data, field information, GIS/Remote Sensing and numerical modelling to understand runoff, drainage behaviour, waterlogging and flood hazards.

  • Hydrological and catchment assessment
  • Rainfall and Intensity-Duration-Frequency (IDF) analysis
  • Design storm and return-period analysis
  • Rainfall-runoff modelling
  • Peak discharge and flood-flow estimation
  • Flood Risk Assessment (FRA)
  • River and channel hydraulic modelling
  • 1D/2D flood inundation modelling
  • Urban waterlogging and drainage assessment
  • Stormwater drainage analysis and planning
  • Flood-depth, extent and hazard mapping
  • Climate-resilient flood-management planning
  • GIS & Remote Sensing-based hydrological analysis
  • HEC-HMS, HEC-RAS and SWMM-based modelling, as applicable

We undertake integrated watershed and river-basin studies for sustainable management of surface water, runoff, soil, drainage systems and water resources. Our approach combines hydrological assessment, terrain analysis, Remote Sensing/GIS and watershed-management principles to identify appropriate conservation and management interventions.

  • Watershed delineation and characterization
  • Drainage and stream-network analysis
  • Morphometric analysis
  • Runoff and water-yield assessment
  • Watershed prioritization
  • Soil-erosion and sediment-risk assessment
  • Surface-water resource assessment
  • River and catchment studies
  • Watershed treatment planning
  • Check dams, nala bunds and water-conservation structures
  • Soil and water conservation planning
  • Lake and catchment restoration studies
  • Irrigation and watershed-management studies
  • GIS & Remote Sensing-based watershed monitoring
  • Integrated river-basin and water-resource planning
