Regional scale hydrology: II. Application of the VIC-2L model to the Weser River, Germany
نویسندگان
چکیده
This paper describes the application of a grid network version of the twolayer Variable Infiltration Capacity (VIC-2L) macroscale hydrological model. The VIC-2L model is implemented on a rotated grid, which is compatible with the weather forecast and climate model REMO (Regional Model), a joint project of the German Weather Service (DWD), GKSS Research Centre and the Max-PlanckInstitute for Meteorology, Hamburg. Observed surface meteorological data in the Weser River basin are used to force the model off-line on a daily time step. After a 22-month calibration period, simulated and measured streamflow data are compared for a 12-year period. The resulting predictions compare well with observations at daily, monthly and annual time scales. A sensitivity analysis is presented. Hydrologie à l'échelle régionale: II. Application du modèle VIC-2L sur la rivière Weser, Allemagne Résumé Cet article décrit l'application du schéma de surface VIC-2L (Variable Infiltration Capacity). Le schéma de surface VIC-2L est implémenté sur un domaine compatible avec le modèle météorologique de prévision et de climat REMO (REgional MOdel), un projet commun du Service Météorologique Allemand (DWD), du centre de recherche GKSS, et de l'Institut Max-Planck pour la météorologie à Hamburg. Les paramètres météorologiques de surface observés sur le bassin versant de la Weser sont utilisés pour forcer le modèle au pas de temps journalier. Après une période de calibration de 22 mois, les débits simulés et observés sont comparés sur une période de 12 ans. Les résultats des simulations se comparent bien avec les observations aux échelles journalière, mensuelle, et annuelle. Une analyse de sensibilité a été faite.

Development of a coupled soil erosion and large‐scale hydrology modeling system
[1] Soil erosion models are usually limited in their application to the field scale; however, the management of land resources requires information at the regional scale. Large‐scale physically based land surface schemes (LSS) provide estimates of regional scale hydrologic processes that contribute to erosion. If scaling issues are adequately addressed, coupling an LSS to a physically based ero...
متن کاملEegional scale hydrology: I. Formulation of the VIC-2L model coupled to a routing model
A grid network version of the two-layer Variable Infiltration Capacity (VIC-2L) macroscale hydrological model is described. The VIC-2L model is a hydrologically-based SVAT (Soil Vegetation Atmospheric Transfer) scheme designed to represent the land surface in numerical weather prediction and climate models. It is coupled to a linear routing scheme which is optimized with measured precipitation ...
متن کاملRiver water quality modelling for river basin and water resources management with a focus on the Saale River, Germany
This thesis focuses on computer modelling issues such as i) uncertainty, including uncertainty in parameters, data input and model structure, ii) model complexity and how it affects uncertainty, iii) scale, as it pertains to scaling calibrated and validated models up or down to different spatial and temporal resolutions, and iv) transferability of a model to a site of the same scale. The discus...
متن کاملModeling methane emissions from the Alaskan Yukon River basin, 1986–2005, by coupling a large-scale hydrological model and a process-based methane model
[1] Much progress has been made in methane modeling for the Arctic. However, there is still large uncertainty in emissions estimates due to the spatial variability in water table depth resulting from complex topographic gradients, and due to variations in methane production and oxidation due to complex freezing and thawing processes. Here we extended an extant methane emission module within a b...
متن کاملA Land-Surface Hydrology Parameterization With Subgrid Variability for General Circulation Models
Most of the existing generation of general circulation models (GCMs) use so-called bucket algorithms to represent land-surface hydrology. Biosphere-atmosphere models that include the transfer of energy, mass, and momentum between the atmosphere and the land surface are a recent alternative to this highly simplified representation of the land surface in GCMs. These models require estimation of a...
