Hydraulic Modeling

G&D is experienced in the development and application of computer hydraulic models, using a variety of software tools, to evaluate sanitary sewer collection systems for the purposes of capacity analysis, guiding I/I control programs, and capital planning. The scope of work often involves:

  • Model selection;
  • Establishing modeling baseline;
  • Temporary flow metering to support model calibration;
  • Model calibration to observed flow under both dry and wet weather conditions;
  • Flow projections;
  • Model evaluation of system performance under existing and future conditions; and
  • Model documentation.
