A Model for the Relationship between the Hydraulic Conductivity and Primary Sedimentary Structures of Till
Hydraulic Conductivity Primary Sedimentary Structures Structures of Till
2009/10/27
An investigation has been made of the relationships between saturated hydraulic
conductivity, porosity and micro-structure of undisturbed lodgement till
samples. 35 measurements with a constant head...
A Test of Snowmelt-Runoff Model for a Major River Basin in Western Himalayas
Snowmelt-Runoff Model Major River Basin Western Himalayas
2009/10/27
In the Snowmelt-Runoff Model (SRM), the estimate of discharge volume is
based on temperature condition in the form of degree days which are used to
melt the snowpack in the area of the basin covered...
A Net Radiation Model for Calculating Daily Snowmelt in Open Environments
Net Radiation Model Daily Snowmelt Open Environments
2009/10/26
Climatological data from three stations in western Canada are used to develop
a model for estimating daily net radiation from station latitude, station altitude
and cloud cover. Expressions describi...
Sulphur and Oxygen Isotopes Behaviour in Sulphates of Atmospheric Ground water System Observations and Model
Sulphur Oxygen Isotopes Behaviour Atmospheric Ground water System
2009/10/26
Comparison of sulphate concentrations in groundwaters and atmospheric precipitation
suggests that about 30 % of groundwater sulphate may be of atmospheric
origin. Another source of sulphate ion is t...
Development of a Process Oriented Calibration Scheme for the HBV Hydrological Model
Process Oriented Calibration Scheme HBV Hydrological Model
2009/10/26
A process oriented calibration scheme (POC), developed for the HBV hydrological
model is presented. Twelve parameters were calibrated in two steps.
Firstly, initial parameter estimates were made fro...
The rapid flow model (equivalent to the distributed delayed Muskingum model)
is an attractive linear flood routing model meeting the conflicting demands
of physical significance and simplicity. Afte...
Worldwide Testing of the Snowmelt Runoff Model with Applications for Predicting the Effects of Climate Change
Worldwide Testing Snowmelt Runoff Model Effects of Climate Change
2009/10/26
The Snowmelt-Runoff Model (SRM), a simple degree-day model, has been
applied to over 50 basins in 15 countries around the world. Where results have
been reported, the average R' has been 0.84 and th...
A Theoretical Model of Thermal Bar Movement in a Circular Lake
Theoretical Model Thermal Bar Movement Circular Lake
2009/10/26
The present paper concentrates on the movement of the spring thermal bar
with time, and a simple theoretical model is derived for the case of an axisymmetric
circular lake. The lake is considered to...
Kinematic Model of River Ice Motion During Dynamic Breakup
Kinematic Model River Ice Motion Dynamic Breakup
2009/10/26
We begin a study of the dynamics of ice motion during river breakup by
formulating a kinematic model. Ice continuity equations are applied to relate
the speeds of a breaking front, a convergence fro...
The CREAMS model, a management model for predicting field-scale runoff
and erosion, has been modified and adapted for Finnish conditions: The most
important changes are the implementation of a new s...
Application of the ETH Snow Model to Three Basins of Different Character in Central Europe
ETH Snow Model Three Basins Central Europe
2009/10/26
The performance of a version of the HBV-ETH model is evaluated, taking into
account various aspect classes in each elevation belt in three different types of
catchments: an alpine basin, and two bas...
An Operational Forecasting Snowmelt Model with Objective Calibration
Operational Forecasting Snowmelt Model Objective Calibration
2009/10/26
After a review of existing operational models for daily snowmelt forecasting,
an operational oriented one has been developed in order to provide a simple
tool for one-to-three-day ahead flow managem...
A numerical hydrological model has been developed for a 450 km2 Danish
catchment using comprehensive field data. The model integrates a simple
evapotranspiration model, a lumped flow model for a phr...

Comparative Model Estimates Interception Loss Coniferous Forest Stand
2009/10/23
Measurements of throughfall in a coniferous forest stand were analyzed and
compared with model estimates of interception loss using three different types
of models: thc Nordic HBV model, the AMOR mo...
A Simple Monthly Runoff Model for Snow Dominated Catchments in Western Himalayas
Monthly Runoff Model Snow Dominated Catchments Western Himalayas
2009/10/23
The rivers originating from middle and greater Himalayas have a significant part
of their catchments under permanent snow cover and glaciers. Modeling runoff
becomes difficult with almost no data fr...
