| A two-dimensional hydraulic model (USGS, 2021) |
"One-dimensional models include mathematical simplifications related to the assumption that flood depth remains uniform over the entire cross section. This assumption is not accurate for wide and flat floodplain areas. Two-dimensional models use full dynamic or simplified forms of one- and two-dimensional shallow water equations to solve both one-dimensional channel flow and two-dimensional overland flow and are more appropriate for flat and wide floodplain areas”.
