Considerable effort has been expended on the theoretical aspects of the applicability
of the unsteady flow equations to natural overland flow. The major
difficulty when these equations are used to s...
Development and Applications of a Runoff Model for Snowcovered and Glacierized Basins
Development Applications Runoff Model Glacierized Basins
<
2009/10/28
A conceptual model has been developed for the prediction of runoff on a
daily basis from snowcovered and glacierized basins. The basin is divided into
an icefree area and an icecovered area, which a...

2009/10/27
Rainfall runoff phenomena in small watersheds are favorably modelled using
the kinematic wave approach. The present investigation considers excess rainfall
as time dependent but ignores spatial effe...
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...

2009/10/26
A physically-based rainfall-runoff model is used to investigate effects of moving
storms on the runoff hydrograph of throughflow dominated idealised catchments.
Simulations are undertaken varying th...
Preliminary Considerations for Runoff Modelling in GCMS

2009/10/26
Modelling of runoff' in GCMs is a two-stage process: first, a residual water
amount resulting from precipitation, evapotranspiration, snowmelt, infiltration
and soil moisture movement at each time s...
