• Floodline determinations, flood risk, and flood hazard assessments.
• Surface water impact assessments.
• 2. Hydraulic Analyses & Design
• Water surface backwater profiling for floodline modeling.
• Flood attenuation calculations for reservoirs and culverts (attenuated volumes, reduced release peak flows).
• Open channel/canal flow design using free surface hydraulic theory.
• Hydraulic design and optimization of spillways integrated with flood routing.
• Energy dissipation and erosion control structure design.
• Dam break analysis.
