| With its state-of-the-art extension,
Subcatchment Manager, InfoSWMM equips wastewater
utilities with extended power and flexibility in
leveraging their mapping and GIS data to support
the modeling of runoff quantity and quality from
subcatchments allowing them to automatically build
accurate, representative models of their sewer systems
with unsurpassed speed and accuracy. Because it
simplifies and streamlines the review, creation,
validation, cleaning, editing and management of
spatial information, the suite enables InfoSWMM
users to make the most of their data and develop
accurate and reliable dynamic sewer models faster
than ever before.
The Subcatchment Manager focuses on minimizing
the tedious tasks associated with sewer network
model construction and data checking. Among its
compelling features, it automatically:
- Converts contours or survey points into Digital
Elevation Models (DEM)
- Identifies and fills sinks in a DEM
- Generates flow direction and flow accumulation
grids to visually identify overland flow paths
- Defines stream vectors and overland flow paths
from flow accumulation grids
- Delineates watersheds utilizing a DEM and threshold value or man-made collection points
- Snaps collection points to flow path within a specified tolerance, greatly increasing the accuracy of delineation
- Smart delineation ignores unreasonably small subcatchments on ridges
- Assigns rain gauges to subcatchments based
on location
- Conducts advanced polygon processing for soils,
land use, and pervious/impervious percentage
layers to globally populate infiltration, pollutant,
and pervious/impervious attributes
- Calculates subcatchment area, width, overland
flow length, and slope
- Generates subcatchments from existing raster
data
- Cuts rasters quickly with any user-defined
polygon
- Easily merges subcatchments using graphical selection
And many more …
