I am trying to model this as a proposed system that ties into an existing system at MH-3. I have set the outfall fixed elevation to 1' below the Rim of MH-3 to simulate a surcharged condition in the existing pipe. I am using hydrodynamic analysis and rational method. Is there a better way to "fix" the starting HGL?

In this Online Storm and Sanitary Analysis (SSA) training course, participants will learn and apply the tools offered by SSA, the Civil 3D companion software for stormwater management and design.

Autodesk Storm and Sanitary Analysis extension for Civil 3D 2011 was realeased in 2010. This extension is a comprehensive, dynamic hydrology and hydraulic analysis application for planning and designing of urban drainage systems, storm sewers including highway drainage systems, and sanitary sewers.

Autodesk Storm and Sanitary Analysis was known before as StormNET. The program is based on SWMM 5.0.022 and it is a dynamic rainfall-runoff-subsurface runoff simulation model used for single-event to long-term (continuous) simulation of the surface/subsurface hydrology quantity and quality from primarily urban/suburban areas. The hydrology component operates on a collection of subcatchment areas that receive precipitation and generate runoff and pollutant loads after simulation of evaporation and infiltration losses from the drainage basin. The hydraulics portion of SWMM is capable of model sanitary and storm water networks with closed pipes, open channels, storage/treatment devices, pumps, orifices, weirs and regulators. SWMM tracks the quantity and quality of the flow generated within each catchment area, and the flow rate, flow depth, and quality of water in each pipe and channel during a simulation period composed of multiple fixed or variable time steps. SWMM is one of the hydrology transport models which the EPA and other agencies have applied widely. There is no limit on the number of links in the network.

Autodesk Storm and Sanitary Analysis 2012 Extension is a comprehensive hydrology and hydraulic analysis application for planning and designing urban drainage systems, highway drainage systems, storm sewers, and sanitary sewers. Major technical capabilities and functionalities include:

Comprehensive input data and output analysis reports can be generated using the built-in report generator. The software allows full customization of input and output reporting. This gives you greater flexibility and functionality in developing specialized user-defined reports. These reports can be fully customized to help meet any combination of modeling criteria.

Autodesk Storm and Sanitary Analysis can share spatial data and visual representation of the stormwater and wastewater sewer network with most GIS spatial databases, allowing the software to be part of the stormwater and wastewater management and planning system. These capabilities can greatly assist the decision-making processes for network asset inventory, rehabilitation requirements, and financial planning. The software can intelligently import most any GIS database structure, using attribute mapping and geocoding. Also, the analysis solution results can be exported back to the GIS database, so locations of CSO and SSO spills, manhole overflows, pipe surcharging, and floodplain flooding can be more quickly identified.

Autodesk Storm and Sanitary Analysis includes a Rainfall Designer which, after you select any location within the U.S., will provide the design rainfall for the specified storm frequency. Alternatively, a user- defined rainfall can be specified. Then the appropriate storm distribution can be selected and the design storm is created. Multiple design storms can be created and analyzed.

Autodesk Storm and Sanitary Analysis contains a flexible set of hydraulic modeling capabilities used to help route runoff and external inflows through the drainage system network of pipes, channels, storage/treatment units, and diversion structures. The software can simultaneously simulate dual drainage networks (stormwater sewer network and city streets as separate but connected conveyance pathways) and inlet capacity. It can quickly determine the amount of stormwater flow that is intercepted by the stormwater network inlets and the amount of stormwater flow that bypasses and is then routed further downstream to other inlets. Hydraulic network modeling is performed by the Kinematic Wave or Hydrodynamic (in other words, Saint Venant equation) routing methods. The software can account for:

On-site, underground stormwater retention/detention can be incorporated into your network model.

Subsurface vaults or systems of large diameter interconnected storage pipes, arched pipes, or manufactured storage chambers can be modeled. The software includes standard storage chambers from leading manufacturers. Choose the storage chamber model from a selection list, define the quantity, backfill dimensions, stone void space, and the software will automatically compute the available storage capacity.

The software can model exfiltration (sometimes called infiltration) at storage nodes, accounting for both stormwater reduction and pollutant removal. Wet and dry retention ponds can be modeled.

The following exfiltration methods are provided:

Autodesk Storm and Sanitary Analysis helps simplify your highway drainage design work. The software can simulate dual drainage systems (stormwater sewer network and city streets as dual conveyance pathways) and inlet capacity. It can more quickly determine the amount of stormwater flow that is intercepted by the stormwater network inlets and the amount of stormwater flow that bypasses and is then routed further downstream to other inlets.

Highway drainage capabilities include:

The hydraulics of storm drain inlets is computed based on the procedures and equations defined in the FHWA Hydraulic Engineering Circular No. 22 (HEC-22), Urban Drainage Design Manual, Third Edition, 2009. The capacity of storm drain inlets on roadway sag is computed by both the weir and orifice equations (FHWA Report, Hydraulic Characteristics of Slotted Drain Inlets, 1980). Flow into the storm drain inlet initially operates as a weir having a crest length equal to the length of drain perimeter that the flow crosses. The storm drain inlet operates under weir conditions to a depth of about 4 inches (100 mm) and then begins to switch to orifice flow.

As part of the NPDES (National Pollutant Discharge Elimination System) permitting process, modeling of stormwater quality and quantity may be required. The software can model all aspects of stormwater quality and quantity, and can incorporate best management practices directly within the model.

The following processes can be modeled for any number of user-defined water quality constituents:

Water quality pollutant buildup accumulates within a land type by either a mass per unit of subbasin area or per unit of street curb length. The amount of buildup is a function of the number of preceding dry weather days (prior to the storm event) and can be computed using one of the following numerical functions.

Water quality pollutant washoff from a given land type occurs during wet weather periods (for example, during a storm event) and can be described in one of the following methods. Note that buildup is continuously depleted as washoff proceeds, and washoff ceases when there is no more pollutant buildup available.

Hydrological and hydraulic effects of urban development is one of the key issues of study for improved water management. The addition of impervious surfaces to once pervious land and re-routing open channels and flow paths can cause flooding or declining water levels within a watershed. Many studies of these issues have found that there can be multiple factors causing hydrological and hydraulic impacts, and it can be hard to analyze and develop effective solutions without appropriate drainage software packages. However, there are multiple software packages available for use, and determining the correct one to use for a specific challenge can often be a case by case decision. This study compares two drainage software packages: Autodesk Storm and Sanitary Analysis (SSA), and the Army Corps of Engineers Hydrologic Modeling System (HEC-HMS). Each of these software packages are used to create a model of the Andre Clark Bird Refuge in Santa Barbara, CA. The models analyze both current conditions and anticipated system response under the assumption that historical runoff from a previously re-routed creek and corresponding watershed are restored. Each model was used to determine the minimum cumulative rainfall that causes circulation of the water body, a maximum cumulative rainfall that causes flooding on site, and response under both routing scenarios to a 2-year frequency storm. Results from both models are compared for uniformity, and application of each model is reviewed for its efficacy as a design tool for this sort of hydrological and hydraulic analysis. e24fc04721
