It is often required to evaluate the performance of a storm sewer system using multiple design storm events. Instead of running the same XPSWMM models using different single design storms…
NOAA Atlas 14 provides the latest official U.S. precipitation frequency (PF) estimates for selected durations and frequencies. For its introduction and basic application including point precipitation depth and temporal distribution,…
XPSWMM can load an image raster file as background to facilitate the drainage network creation. The image file needs to have a world file associated with so that XPSWMM is…
To perform 2D modeling using XPSWMM, a surface dtm file (*.xptin) needs to be generate first in XPSWMM. Another option to create a 2D surface is Reference a Grid File…
A big size raster file usually can be compressed to reduce its size. A lot of QGIS raster tools/commands have a built-in option to select a method to compress a…
In HEC-RAS 2D modeling, manning's n values (Roughness Coefficient) for 2D flow area are normally associated with land cover types and used to account for energy friction losses of overland…
