Incorporating Wetland Delineation and Impacts in Watershed-Scale Hydrologic Modeling

In semi-distributed hydrologic models, it is difficult to account for the impacts of wetlands on processes, as they are based lumped, subbasin-scale wetland concepts. It a challenge incorporate influences individual small into watershed-scale models by using lumped parameterization. The objective this study was improve modeling taking real features during To achieve objective, joint framework proposed couple surface delineation algorithm with model and then applied Upper Turtle River watershed in North Dakota, USA. identified topographic properties wetlands, which were further utilized A nonlinear area–storage relationship determined used estimation wetland-related parameters. results demonstrated that new approach effectively avoided misestimating parameters accounting characteristics (e.g., storage, ponding area, contributing area) their influences, provided improved processes such wetland-dominated watershed.
