Parameter regionalization
WebThe similarity-based hydrological regionalization approach is used in this study to transfer model parameters from gauged to ungauged catchments. Thus, the uncertainties surrounding the regionalization procedure should be evaluated by applying a cross-validation procedure to assess the regionalization skill ( Wang et al., 2024 ). WebHydrological similarity-based parameter regionalization is the dominant method used for runoff prediction in ungauged basin. However, the application of this approach depends on assessing … Expand. 4. PDF. Save. Alert.

WebThe Multiscale Parameter Regionalization Technique mHM requires at most 28 parameters (depending of the configuration) per cell to account for the spatial variability of the dominant hydrological processes at a mesoscale river basin. These effective parameters have to be estimated through calibration. WebAug 30, 2024 · 1.1 Regionalization of Hydrological Model Parameter Values Continuous daily streamflow information is crucial for many practical purposes related to assessing and managing water resources or water-related hazards. However, many catchments of interest are poorly gauged or ungauged and lack the required hydrological information.
WebJun 23, 2024 · Commonly used parameter regionalization methods can be categorized as follows: (1) the parametric transplantation method, where a reference area that is spatially near or has similar climate characteristics to the target area is first selected, and then the parameters of the reference area are extended to the target area (Cheng et al., 2016); … WebDec 20, 2024 · These parameter maps are used as input for the distributed hydrological model to produce predictions (e.g., discharge and evapotranspiration). These predictions are then compared against observations using a loss function. Within this study, a mean loss is calculated over all observation gauges.
