thanks for sharing my comments. An...Dear Riccardo,<br /><br />thanks for sharing my comments. Anyhow, I would like to draw your attention to this very recent paper published (yesterday) on JoH:<br />Cornelissen, T., Diekkrüger, B. Bogena, H.R. (2014). Significance of scale and lower boundary condition in the 3D simulation of hydrological processes and soil moisture variability in a forested headwater catchment, Journal of Hydrology, in press, doi: 10.1016/j.jhydrol.2014.01.060. <br />http://dx.doi.org/10.1016/j.jhydrol.2014.01.060.<br /><br />The manuscript describes a very interesting effort to model discharge and soil moisture through a physically based spatially distributed hydrogeological model (HGS) in a very well instrumented small catchment (Wustebach, 0.27 km²) in western Germany. Specifically, the soil moisture dataset collected in the catchment is really impressive (900 sensors!!!).<br /><br />However.... the HGS model failed to simulate the spatial variability of soil moisture observations, or alternatively, the spatial variability of observed data is different from the modelled data (see Figures 6, 7, and 8 and the Kappa value in section 4.3).<br /><br />My question is: why is the model wrong in reproducing soil moisture SPATIAL variability?<br />The authors underline that the model doesn't simulate the macropore flow (and the flow in the fractures) and this could be one reason.<br />Further reasons: 1) uncertainty in the measured data that increases their standard deviation (see Brocca et al., 2013, JoH), 2) wrong SPATIAL parameterization of the hydrological model (e.g. the soil layer thickness).<br />Other reasons???Anonymoushttps://www.blogger.com/profile/17485667273900708181noreply@blogger.comtag:blogger.com,1999:blog-6687556278632539882.post-59938714998656020062014-01-22T05:20:05.857+01:002014-01-22T05:20:05.857+01:00Thank you for posting this valuable short article....Thank you for posting this valuable short article.
