Todd Creek Sewershed: Data Analysis
A hydraulic model was prepared of 10-inch and greater diameter sanitary sewer lines in the Todd Creek Sewershed. Key elements:
- Development of Subcatchment Shapefiles. This included identifying manhole loading points for sanitary flow modeling.
- Model Basis. An InfoWorks Transportable Database was imported into InfoNet as the basis for the model.
- Supplemental Data. Additional data were obtained from an OCP GIS database, City Sewer Records, bid documents for the Second Creek Interim Pump Station and a TIN surface model. Missing data were inferred using InfoNet Inference Tools, and engineering judgment to resolve data inconsistencies.
