  • Bank protection works like revetments, pitching
River Training
  • Location, orientation, adequacy of waterway, afflux, safe deck levels
  • Scour level and foundation level, protection measures
  • Appurtenant Structures such as guide bunds, approach / afflux embankments
  • Morphology to examine stability of river course
Barrages and Weirs
  • Layout, orientation and waterway, afflux
  • Crest levels of spillway and undersluices
  • Hydraulic design parameters : velocities, discharge intensity / distribution
  • Schedule of gate operation
