This study was conducted to determine if the Agricultural Policy/Environmental Extender (APEX) model could reasonably replicate the effects of silvicultural practices on streamflow and loading of sediments and nutrients. APEX was modified to enhance factors associated with forestry conditions such as rainfall interception by canopy, litter, subsurface flow, nutrient movement, and routing enrich...

13 Abstract— The dynamic ecosystem model LPJ-GUESS includes 14 explicit representation of vegetation dynamics as well as soil 15 biogeochemistry, and has been widely and successfully 16 implemented in predicting vegetation biomass and carbon cycling 17 at different scales. However, the water cycling for each grid cell in 18 the model is only considering the movement between atmosphere, 19 veget...

Estimation of runoff volume and sediment load is a problem that directly affects the performance of dams due to the reduction in the storage capacity of their reservoirs and their effect on dam efficiency and operation schedule. The simulation models can be considered for evaluation of sediment potential if the continuous field measurements are not available. Soil and Water Assessment Tool (SWA...

The northwest Greenland Ice Sheet (NW GrIS) is rapidly losing mass, and its ablation zone has expanded over the past two decades. Numerous supraglacial streams flowing directly NW GrIS surface drain a large lobe of grounded ice at Inglefield Land, into proglacial Minturn River Nares Strait. Owing to absence moulins crevasses, this continuous supraglacial-proglacial drainage system regulates eva...

Abstract Supraglacial lakes and rivers dominate the storage transport of meltwater on southwest Greenland Ice Sheet (GrIS) surface. Despite functioning as interconnected hydrologic networks, supraglacial are commonly studied independent features, resulting in an incomplete understanding their collective impact routing. We use Landsat 8 satellite imagery to assess seasonal evolution GrIS during ...
