Instead of being modeled in 1D HEC-RAS by storage area and inline structure, reservoir and dam can also be modeled in 2D HEC-RAS by storage area + SA/2D connection +…

In HEC-RAS 2D Rain-on-Grid (ROG) modeling, three layers are needed to model the infiltration loss and the procedures to create the three layers have been discussed before. Land Cover Layer…
XPSWMM is a popular 1D and 2D hydrologic and hydraulic modeling tool developed by Innovyze. Though originally XPSWMM was designed primarily to model storm sewer network system, it has gained…
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…
For unsteady state 1D and 2D HEC-RAS models, initial conditions must be set up appropriately to not make the model crash or become unstable at the beginning of the modeling.…
To model infiltration loss within 2D domain for a Rain-on-Grid (RoG) HEC-RAS model, a land cover layer and a soils layer needs to be generated first and then an infiltration…
A bridge can be modeled in 2D domains using a geometry editor similar to 1D bridge geometry editor since HEC-RAS 6.0. HEC-RAS manual defines this method as Simplified 1D/2D Bridge…
