DEM-based topographic characterization and quantification of surface depression storage are critical to hydrologic and environmental modeling. Mixed conclusions have been obtained from previous studies on the relationship between maximum depression storage (MDS) and DEM grid spacing, which is affected by different factors, such as topographic characteristics, surface delineation methods and DEM...

MassMov2D is a numerical model for simulating runout and deposition of landslide phenomena over a complex topography that is implemented in the free GIS PCRaster. This research aims at improving the mechanism of MassMov2D calibration and verifying its capability of representing complex landslides. In this paper the authors present the enhancement of the MassMov2D code due to the introduction of...

The vertical motion of the Earth’s surface is dominated by hydrologic cycle on a seasonal scale. Accurate land deformation measurements can provide constructive insight into regional geophysical process. Although Global Positioning System (GPS) delivers relatively accurate measurements, GPS networks are not uniformly distributed across globe, posing challenge to obtaining information in data-sp...

Accurate terrestrial water storage (TWS) estimation is important to evaluate the situation of the water resources over the Yangtze River Basin (YRB). This study exploits the TWS observation from the new temporal gravity field model, HUST-Grace2016 (Huazhong University of Science and Technology), which is developed by a new low-frequency noise processing strategy. A novel GRACE (Gravity Recovery...

Abstract. Global hydrological models have become a valuable tool for range of global impact studies related to water resources. However, glacier parameterization is often simplistic or non-existent in models. By contrast, do represent complex dynamics and evolution, as such, they hold the promise better resolving runoff estimates. In this study, we test hypothesis that coupling model with leads...

The KIDS model (Kielstau Discharge Simulation model) is a simple rainfall-runoff model developed originally for the Kielstau catchment. To extend its range of application we applied it to a completely different catchment, the XitaoXi catchment in China. Kielstau is a small (51 km2) lowland basin in Northern Germany, with large proportion of wetland area. And XitaoXi is a mesoscale (2271 km2) mo...
