1-D, 2-D, CFD and Physical Hydraulic Modeling
S2o uses several different modeling techniques to ensure the accuracy of the project from design through construction. In addition to new projects, S2O’s models have been used to evaluate designs created by competing firms and have been credited with saving clients hundreds of thousands of dollars in required fixes and changes. These techniques include:
- Computer Modeling: S2O performs 1-D, 2-D and 3-D computational fluid dynamics models.
These models include floodplain models, HEC-RAS models, pump and intake models, and fish passage and whitewater models. We also utilize these models to preform detailed analysis, of the stresses in a whitewater channel.
- Floodplain Modeling: S2o provides floodplain modeling for use with the Federal Emergency Management Agency’s (FEMA) National Flood Insurance Program (NFIP). We plan and coordinate topographic and bathymetric surveys, create Digital Terrain Models (DTM), develop 1D hydraulic models using HEC-RAS software, assess proposed impacts to the effective floodplain and floodway, and create tabular and graphical figures and floodplain delineations for compliance with applicable Federal regulations. We are also experienced with ArcGIS and HECGeoRAS and capable of producing flood maps compatible with FEMA’s Flood Map Modernization Program.
- Physical Modeling: S2O provides in-house physical modelling services, including bypass channels, river models, Olympic and recreational channels, and feature-specific whitewater models. S2O’s scale models have been used to accurately predict flows and have been cited by the International Canoe Federation as “the first models I’ve seen that accurately predict what the final product will become.”
- Construction Modeling: S2O designs its channels in three dimensions using AutoCad Civil 3D.
S2O’s use of this software has been cited as “innovative” by a leading Civil3D authority. The adaptation of this software to whitewater channel design allows S2O to benefit from the accuracy of 3-dimensional design.
