Effect of land use-based surface roughness on hydrologic model output
land use-based surface roughness hydrologic model coefficient Manning
2015/8/14
The Manning’s roughness coefficient (n) is commonly used to represent surface roughness in lumped and distributed hydrologic models. Model parameter sensitivity studies identify runoff response to be ...
Verification and application of a mathematical model for the assessment of the effect of guiding walls on the hydraulic efficiency of chlorination tanks
mathematical model assessment guiding walls hydraulic efficiency chlorination tanks
2009/12/4
A mathematical model is applied to the tank of Kipseli in Athens, Greece, which is used for storage, balancing and emergency chlorination. A Flow-Through Curve (FTC) experiment is performed for the in...
Effect of Local Bottom Slope and Roughness Coefficient Variations in Overland Flows
Local Bottom Slope Roughness Coefficient Variations Overland Flows
2009/10/28
The investigation analyses the effects of local bottom slope and roughness
coefficient variations in overland flow over a plane by using the kinematic
wave theory. Results are compared with the usua...
On the Physico-Chemical Basis for the Capillary Barrier Effect
Physico-Chemical Basis Capillary Barrier Effect
2009/10/27
The capillary barrier concept, using fine and coarse soil layers to reduce water
infiltration into piles of hazardous wastes, is investigated theoretically. A detailed
account of the hydrological an...
The Effect of Heterogeneity on Large Scale Solute Transport in the Unsaturated Zone
Effect of Heterogeneity Large Scale Solute Transport Unsaturated Zone
2009/10/27
The effect of natural heterogeneity on large scale solute transport in the unsaturated
zone is investigated using stochastic methods. Several of the physical
parameters that control flow and solute ...
Simulation of Soil Frost Depth and Effect on Runoff
Simulation Soil Frost Depth Effect on Runoff
2009/10/27
A physically based soil frost depth model usable with air temperature data and
precipitation data, is presented. Snow depth is calculated from precipitation
data using a physical snow cover model. T...
Assessing the Effect of Longitudinal Density Gradient on Estuarine Hydrodynamics
Longitudinal Density Gradient Estuarine Hydrodynamics
2009/10/27
If the im$act of longitudinal density gradient on the hydrodynamics of estuaries
is negligible, then in water quality simulations, the hydrodynamics can be
decoupled from the mass transport which wo...
MODELING THE EFFECT OF SOIL, VEGETATION TYPE AND DENSITY ON SOIL MOISTURE AND SURFACE ENERGY FLUX
Soil moisture SURFACE ENERGY FLUX atmospheric dynamics
2009/10/12
Soil moisture plays a crucial role in hydrological modeling and land-atmosphere energy balance by controlling the amount of evaporation and thermal heat exchange between the land surface and overlying...
The effect of surrounding topography on the thermal water circulation in moraine-dammed glacial lakes：Imja and Tsho Rolpa Lakes in the Himalayas
Himalayan glacial lake wind system screening effect barrier effect airflow simulation
2009/7/14
The observations in the pre-monsoon seasons of 1996 and 1997 indicated that two moraine-dammed glacial lakes, Tsho Rolpa and Imja, in the Nepal Himalayas have the different thermal structure in spite ...
