Fast Model Calibration with InfoSWMM Calibrator
InfoSWMM Calibrator enables you to calibrate very large and complex urban rainfall-runoff models automatically and rapidly, leading to better analysis and design. It integrates and exchanges data with existing network models and GISs.
It considers any combination of flow, depth, and/or velocity measurements. It quickly adjusts user-selected model parameters to best reflect what is actually occurring in the system. Five distinct groups of urban drainage network parameters, and any combination, can be automatically determined. These are:
- Subcatchment groups such as subcatchment runoff parameters and groundwater parameters including area, width, percent imperviousness, slope, Manning's N for pervious and impervious subareas, depression storage for pervious and impervious subareas, Colorado Urban Hydrograph Procedure parameters such as length, centroid distance, CIA fraction, RPA fraction, lag time for Natural Resources Conservation Service's dimensionless and triangular unit hydrograph method, groundwater flow coefficient, surface water flow coefficient, groundwater flow exponent, surface water flow exponent, surface-groundwater interaction coefficient).
- Soil groups (i.e., infiltration parameters) including Horton's Infiltration parameters such as maximum infiltration rate, minimum infiltration rate, decay rate, drying time, maximum volume; Green-Ampt parameters such as suction, conductivity, initial deficit and Curve Number parameters such as curve number, conductivity, and drying time.
- Aquifer group including porosity, wilting point, field capacity, conductivity, conductivity slope, tension slope, upper evaporation fraction, lower evaporation depth, bottom elevation, water table elevation, and unsaturated zone moisture.
- RDII group (i.e. RDII unit hydrograph parameters) including R, T, and K for short-term, medium-term, and long-term responses.
- Conduit group which includes the Manning's roughness coefficient.
The parameters are not allowed to exceed the maximum or be less than their minimum physically-meaningful limits.
InfoSWMM Calibrator offers a range of goodness-of-fit evaluation criteria.
You can see the results as tables, graphs, correlation plots and statistical summaries.
To use InfoSWMM Calibrator, you need InfoSWMM.
InfoSWMM DWF Allocator (Dry Weather Flow)
InfoSWMM DWF Allocator enables stormwater and wastewater engineers to simplify and automate the process of generating and allocating sanitary loadings for existing system conditions and for various planning horizons.
It computes and assigns wastewater loads generated by your various customer categories (such as land use and population characteristics, sanitary service areas, and ownership parcel data), considering existing system conditions, future developments and various planning horizons - an indispensable aid in staging capital improvement programs.
It fully supports ArcGIS Definition Queries, so that master planners and model builders can use any subset of GIS data. Working with huge data sets as part of your model build process is no longer an issue. This is especially important in regards to use of the DWF (Dry Weather Flow) Load Allocator.
In a typical large system, there can be hundreds of thousands of meter records, or, when water meter records are not available for a sewer system, Equivalent Residential Units (ERUs) to identify DWF Sewer loads. Allocating loads for these huge numbers of meters or ERUs can be extremely time consuming. With DWF Allocator, you can use a simple Definition Query to identify only meters that meet your needs, such as:
- Commercial, residential, industrial, and others
- Ones that match a geographical areas such as each pressure zone, City A out of a County's worth of meter data, or other geographical data
You’ll save hours to weeks of manipulation time for your model background data.
To use InfoSWMM DWF Allocator, you need InfoSWMM.
Determining wastewater contributions and the spatial distribution of these flows throughout the network model is a key element of sewer collection system modeling. Models are loaded with existing and future flows (existing and future developments), depending on the type of analysis to be performed. All collection features, sewer trunks and available storage within the system are supporting elements that provide flow routing of these system loads. The variation of load during the course of a day must also be accounted for during a kinematic or dynamic wave analysis.
Temporal characteristics, typically represented by their respective diurnal variations (hydrographs), are also required. Generally, the sewer loading factors are first estimated for all loading categories. The temporal effects of sewage flows are then adjusted based on individual sewer production categories. A spatial intersection then geographically allocates these generated flows to the appropriate sewer manholes, thereby defining system loading. Finally a load factor calculator then modifies the load factors to match a known treatment plant inflow, completing the allocation process.
