Improving Hydrological Models of The Netherlands Using ALOS PALSAR
conference paper
In this paper the improvement of the hydrological model metaSWAP of The Netherlands, with respect to soil moisture, is studied using remote sensing data. Therefore we investigate the value of ALOS PALSAR data of 2007 in combination with the method of Dubois et al. [1] for measuring volumetric moisture content. Study area is the eastern part of the water board Hoogheemraadschap De Stichtse Rijnlanden, southeast of the city of Utrecht in The Netherlands. Comparing the results of Dubois’ empirical model with the metaSWAP calculations resulted in a Root Mean Square Error (RMSE) of 12 % (24 March 2007) and 17 % (9 May 2007). In both cases ALOS PALSAR underestimates metaSWAP. The second RMSE is higher than the first due to rainfall during acquisition.
