Hydrologic Modeling

Hydrologic modeling uses mathematical models to replicate the hydrologic processes. These models together with hydraulic models are typically used to assess stormwater system performance under various storm events.

GeoAdvice has extensive experience with the following services:

  • Model Build and Calibration/Validation
  • Stormwater Low Impact Development (LID) / Best Management Practice (BMP) Control
  • Climate Change Impact Analysis
  • Continuous Simulation
  • System Performance Assessment
  • Sizing Drainage System Components
  • Floodplain Modeling
  • Integrated 1D-2D Modeling
  • Flow Monitoring Data Review
  • Integrated Stormwater Management Plan (ISMP)
  • Drainage Management Plan (DMP)
  • Watershed Management Plan (WMP)

Our team are experts in the use of several modeling platforms. GeoAdvice has extensive experience with the following software:

The above software packages are based on the Storm Water Management Model (SWMM) developed by the USA Environment Protection Agency (EPA). SWMM account for various hydrologic processes that produce runoff. These include:

  • Time-varying rainfall;
  • Evaporation of standing surface water;
  • Snow accumulation and melting;
  • Rainfall interception from depression storage;
  • Infiltration of rainfall into unsaturated soil layers;
  • Percolation of infiltrated water into groundwater layer;
  • Interflow between groundwater and the drainage system;
  • Nonlinear reservoir routing of overland flow; and
  • Runoff reduction via LID controls.

GeoAdvice has extensive experience building and analyzing hydraulic and hydrologic models for various stormwater/drainage studies. We encourage you to contact us to learn more about the services we provide.
