Spatial sensitivity analysis of snow cover data in a distributed rainfall-runoff model

Abstract: Abstract. As the availability of spatially distributed data sets for distributed rainfall-runoff modelling is strongly increasing, more attention should be paid to the influence of the quality of the data on the calibration. While a lot of progress has been made on using distributed data in simulations of hydrological models, sensitivity of spatial data with respect to model results is not well understood. In this paper we develop a spatial sensitivity analysis method for spatial input data (snow cover fractio… Show more

“…This made the combined approach simple and robust when used with appropriate multiple metrics. It should be noted that LHS-OAT has been validated in different study areas [5,19]. Although the parameter interactions are not evaluated explicitly, the identified parameters seem to be the most important and relevant parameters for calibration.…”

“…The basic idea behind any sensitivity analysis (SA) method is to relate the response of the model output to variations in the parameter values [4]. The SA methods can, therefore, enhance our control on spatiotemporal model behavior [5]. There are local (LSA) and global sensitivity analysis (GSA) methods that evaluate distinct and joint effects between different model parameters, respectively [6][7][8].…”

“…This paper utilizes monthly patterns of AET first to understand and organize ET related model spatial parameterisations then to pursue a calibration. This is from the fact that adding only temporal aspect of the spatial observations to the objective function is not sufficient for achieving significant 20 (Berezowski et al, 2015). In the context of spatial model calibration, the sensitivity analysis should not only identify the parameters that affect the water balance and hydrograph dynamics but also the parameters that shape the spatial patterns of the simulated states and fluxes.…”

“…Prior to model calibration, sensitivity analysis is usually conducted to attribute response of the model outputs to the changes in model parameters (Shin et al, 2013), which can enhance our understanding of both temporal and spatial model behaviour (Berezowski et al, 2015). In the context of spatial model calibration, the sensitivity analysis should not only identify the parameters that affect the water balance and hydrograph dynamics but also the parameters that shape the spatial patterns of the simulated states and fluxes.…”
