Network Analysis Tool

  • Analyze network connectivity problems and displays the result in ArcMap

  • Visually displays exactly where the issue exists

  • Finds the connected components and shows how they are disconnected

  • Shows where the links and nodes are missing

  • Finds where the network is physically connected, but logically disconnected due to wrong data entry

  • Shows where the same location have multiple nodes or links

  • Finds out the nodes and links that have the same ids

  • Finds out the unused nodes

  • Find links and nodes with invalid geometry

Conduit Roughness

  • Assign conduit roughness values based on conduit material
  • Optionally assign roughness based on the combination of conduit cross section type and material
  • Use SWMM reference table or external data file to assign suitable roughness

Width calculation

  • Determines characteristic width of sub-watersheds for hydrologic analysis.

  • Allows users to adjust effective channel length and overland flow path length during calculation, thereby makes better approximation of system characteristics.

  • Allows users to quickly find the head-watersheds, and their longest flow path lengths from a DEM.

  • Special length adjustment provisions are kept for head-watersheds. Users can adjust the parameter in a table.

  • Use two most reliable width calculation methods to determine the width.

Slope Calculation

  • Find average surface slope of model sub-catchments using DEM dataset
  • Calculate slope as weighted average of the intersected raster cells

Land Use Property

  • Comprehensive options to reclassify a reference land cover data (e.g. the USGS NLCD 2011 land cover data) to the simplified land use types for SWMM
  • Assign suitable values for the Manning’s N and the depth of the maximum depression storage for each land use type from reference table
  • Load previous reclassification or save reclassification for later use
  • Calculate N- and D- values for sub-catchments as weighted average of intersected land cover

Watershed Delineation Tool

  • Delineates subwatershed boundaries for hydrologic analysis and simulation
  • Allows automatic adjustment of raw DEM data for smooth processing of subwatershed delineation

  • DEM raster clipping option to accurately specify the study area and accelerate delineation process

  • Advanced stream-burning option allows to account for existing channel layout during delineation process

  • Create and manage stream layer for the delineated subwatersheds

  • Specify and manage outlet locations at stream confluences, using existing layer or by manual digitization

Imperviousness

  • Find the area-weighted average surface imperviousness of subcatchments
  • Raster or polygon feature can use to find surface imperviousness

Model Creation From Existing GIS Data

  • Efficiently design a complete model
  • Drag-drop GIS Layer data into model
  • Extracts model information directly from the external GIS data source and assigns them perfectly to the model components.

Automatic calculation of geometrical properties of model elements

  • Populate sub-catchment area and conduit length automatically from gis.
  • Use user defined area or length for model adjustments.
  • Run the model using automatically calculated values or user defined values according to modeler’s preference.

Input File to Model And Export Model to .inp File

  • EPASWMM standard .inp file export
  • Build model from existing .inp file
  • Data validation with projection system checking during model creation

  • Build model from existing .inp file
  • Data validation with projection system checking during model creation

Tabular view of model data

  • View all the model elements of one category in table
  • Easily update model data using the tabular view
  • Both simple and composite data for each element can be updated from tabular view.

Control Rules Editor

  • Avoid error in defining control rules using self guided rule editor
  • Create control rules simply by clicking and entering some values in suitable fields

  • Validate control rules even before leaving the editor

View Profile Plot

  • View all available paths between a start node and end node.
  • Generate water surface elevation profiles along with the links for desired path.
  • Run simulation of the surface elevation based on predefined time length.
  • Simulation can be paused, forwarded and rewound.

View Time Series Comparison

  • Time Series Comparison illustrating the comparison between a pair of variables, e.g. flow rate in a pipe vs. water depth at a node with respect to time.
  • Fast and accurate system modeling, analysis and design for visual comparison of input time series and results.

View Output Result in Table Format

  • Enables to list and view time series output results of a single object in a table.
  • Table data exportable to .csv format
