Simulation of Discharge using Different Methods of Meteorological Data Distribution,Basin Discretization and Snow Modelling
Simulation of Discharge Meteorological Data Basin Discretization Snow Modelling
2009/10/26
This contribution investigates the performance of discharge modelling when
proceeding from rather simple methods of snowmelt modelling to more sophisticated,
distributed approaches. In all cases, th...
Long-Term Records of Snow Cover Water Equivalent in the Swiss Alps 2.Simulation
Long-Term Records Snow Cover Water Equivalent Swiss Alps Simulation
2009/10/26
The knowledge of the temporary snow-water equivalent storage term (SWE) is
an important prerequisite for the assessment of short- and long-term runoff
volumes and water quality aspects. Since SWE me...
Simulation of Snowmelt in a Subarctic Spruce Woodland:Scale Considerations
Simulation of Snowmelt Subarctic Spruce Woodland Scale Considerations
2009/10/23
Subarctic woodlands comprise stands of spruce trees with varying degrees of
openness, giving rise to large contrasts in melt rates within the forest. The spatial
variability of the changing snow dep...
Simulation of a Biogeochemical Model in Different Lakes
Simulation Biogeochemical Model Different Lakes
2009/10/22
Eutrophication, caused by nutrients leached from soil and emitted from point
sources, is a well-known problem in many Swedish lakes. There are several
countermeasures that can be used to reduce eutr...
NUMERICAL SIMULATION OF FLOW AND CONTAMINANT MIGRATION AT A MUNICIPAL LANDFILL
NUMERICAL SIMULATION MUNICIPAL LANDFILL FLOW AND CONTAMINANT MIGRATION
2009/10/13
The flow and transport characteristics of the Ano Liosia Landfill site in Athens, Greece, were simulated by numerical methods using groundwater flow and contaminant transport models. A methodology for...

2009/10/13
A soil water model of one dimensional flow, using the Runge-Kutta Gill algorithm, is described with the aim of forming a flexible general purpose simulation tool. The problem of 憇tiffness?appearing in...
EVALUATION OF THE HEC-1 MODEL FOR FLOOD FORECASTING AND SIMULATION IN THE HORMOZGAN PROVINCE, IRAN
Hormozgan province rainfall-runoff flood simulation
2009/10/13
Frequent flood occurrences in the Hormozgan province in the south of Iran cause immense damage to infrastructure, parts of cities and numerous villages, and also claim a number of lives. To study floo...
RAINFALL-RUNOFF SIMULATION IN AN EXPERIMENTAL BASIN USING GIS METHODS
rainfall-runoff travel time map steep watershed
2009/10/12
A GIS-based rainfall-runoff model was developed to simulate the runoff discharge at the outlet of a 15.18 km2 gauged steep watershed that is located at the prefecture of Attica, Greece. The model抯 cor...
LABORATORY SIMULATION OF A GEOMORPHOLOGICAL RUNOFF ROUTING MODEL USING LIQUID ANALOG CIRCUITS
Artificial Neural Network river management precipitation modeling
2009/10/12
The first step in a river management program is precipitation modeling over the watershed. Considering the high stochastic property of the process, many models are still being developed to define this...
Uncertainty in parameterisation and model structure affect simulation results in coupled ecohydrological models

2009/10/10
In this paper we develop and apply a conceptual ecohydrological model to investigate the effects of model structure and parameter uncertainty on the simulation of vegetation structure and hydrological...
Simulation and validation of concentrated subsurface lateral flow paths in an agricultural landscape
Simulation validation lateral flow paths agricultural landscape
2009/9/11
The importance of soil water flow paths to the transport of nutrients and contaminants has long been recognized. However, effective means of detecting concentrated subsurface flow paths in a large lan...

Aiming at developing real time water balance modelling for irrigation scheduling, this study assesses the accuracy of using the reference evapotranspiration (ETo) estimated from daily weather forecast...
Influence of thermodynamic soil and vegetation parameterizations on the simulation of soil temperature states and surface fluxes by the Noah LSM over a Tibetan plateau site
thermodynamic soil soil temperature states vegetation parameterizations
2009/7/22
In this paper, we investigate the ability of the Noah Land Surface Model (LSM) to simulate temperature states in the soil profile and surface fluxes measured during a 7-day dry period at a micrometeor...
Comparison between field measurements and numerical simulation of steady-state solute transport in a heterogeneous soil profile
