RISStochastic Upscaling for Snow Accumulation and Melt Processes with PDF Approach
Publisher: American Society of Civil Engineers
Abstract: Although the importance of subgrid variability in the snow model has been recognized, only a few modeling studies on the parameterization of subgrid effects have been performed. This study proposes a new upscaling approach ...
Upscaling of Coupled Land Surface Process Modeling for Heterogeneous Landscapes: Stochastic Approach
Publisher: American Society of Civil Engineers
Abstract: Land surfaces are spatially inhomogeneous at the spatial scales of vegetation canopies to watersheds or even continents. The spatial heterogeneity strongly affects heat, momentum, and vapor exchange at the land surface. ...
Water Balance Study for the Tigris-Euphrates River Basin
Publisher: American Society of Civil Engineers
Abstract: Several case studies of the Tigris-Euphrates (TE) river basin were performed to investigate the effects of various water resource utilizations on dynamic water balances of the watershed. A daily dynamic water balance model ...
Physically Based Estimation of Maximum Precipitation over American River Watershed, California
Publisher: American Society of Civil Engineers
Abstract: A methodology for maximum precipitation (MP) estimation that uses a physically based numerical atmospheric model is proposed in this paper. As a case study, the model-based 72-h MP was estimated for the American River ...
Coupled Regional Hydroclimate Model and Its Application to the Tigris-Euphrates Basin
Publisher: American Society of Civil Engineers
Abstract: To establish a basinwide water management plan for the Tigris-Euphrates (TE) watershed, it is necessary to perform rigorous water balance studies of the whole watershed—at least for critical historical drought and flood ...
Reconstruction of Historical Atmospheric Data by a Hydroclimate Model for the Mekong River Basin
Publisher: American Society of Civil Engineers
Abstract: It is necessary to have historical atmospheric data at fine time and spatial grid resolutions as input to watershed-scale models of the Mekong River Basin to perform water balance studies over the basin. However, such ...
Impact of Water Resources Utilization on the Hydrology of Mesopotamian Marshlands
Publisher: American Society of Civil Engineers
Abstract: The Mesopotamian Marshlands used to be the largest wetland ecosystem in the Middle East and western Eurasia. These marshlands once covered more than 15,000–20,000 sq km with permanent lakes and marshes, seasonal marshes, ...
Regional Modeling of Climate Change Impact on Peninsular Malaysia Water Resources
Publisher: American Society of Civil Engineers
Abstract: The future projections of climate change by means of global climate models of the Earth provide fundamental coarse-grid-resolution hydroclimate data for studies of the effect of climate change on water resources. This paper ...
Role of Snow in Runoff Processes in a Subalpine Hillslope: Field Study in the Ward Creek Watershed, Lake Tahoe, California, during 2000 and 2001 Water Years
Publisher: American Society of Civil Engineers
Abstract: Field study is an essential component of hydrologic science because all hydrological studies must be conducted by such observation-based knowledge of real watersheds. Hillslope runoff processes have been intensively ...
WEHY-HCM for Modeling Interactive Atmospheric-Hydrologic Processes at Watershed Scale. II: Model Application to Ungauged and Sparsely Gauged Watersheds
Publisher: American Society of Civil Engineers
Abstract: The objective of this study is to evaluate the potential of the Watershed Environmental Hydrology Hydro-Climate Model (WEHY-HCM) for modeling runoff at ungauged or sparsely gauged watersheds. The WEHY-HCM employs an ...
