Design and Analysis of Man-made and Natural Stormwater Drainage Systems

Controlling urban runoff, implementing flood control policy, and protecting the water quality of receiving waters is a necessary and integral aspect of managing the impact of developments on the natural environment. Bentley is a recognized leader in the analysis and design of water resources infrastructure with its Haestad Methods product portfolio.

Coupling Haestad’s hydrologic and hydraulic analysis and design offering with the family of MicroStation platform based solutions for roadway and civil site development yields a complete solution for stormwater collection and management that addresses a number of key areas:

      • Catchment Modeling – delineate and characterize drainage areas then compute pre- and post-developed runoff discharged into natural and man-made receiving waters
      • Sewer Capacity –verify the ability of man-made storm and combined sanitary sewer systems to safely collect, convey, and discharge flows
      • Stormwater Management – quantify impact and manage stormwater discharges from development and construction and verify that developed site impacts meet governing requirements
      • Regional Watersheds – perform analysis for master drainage plans and studies developing structural and non-structural controls of quantity and quality of runoff for mixed urban and rural watersheds
      • Design – size and document the design of proposed stormwater collection systems serving residential and commercial developments, urban section roadways, rural highways and culverts, and man-made impoundments
      • Maintenance and Operation – map and manage drainage easements, environmental reporting, and perform rehabilitation analyses

This full set of functionality and more is delivered in Bentley’s solution that covers the industry standard set of hydrology and hydraulics analysis and civil design tools.
