Identification of support vector machines for runoff modelling
Identification support vector machines runoff modelling
2009/12/4
This paper describes an exploration in using SVM (Support Vector Machine) models, which were initially developed in the Machine Learning community, in flood forecasting, with the focus on the identifi...
Analysis of the Rainfall-Runoff Transformation Process
Analysis Rainfall-Runoff Transformation Process
2009/10/28
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...

Investigation Influence of Rainfall Movement Runoff Hydrograph Real Catchments
2009/10/28
Work presented here consists of two parts: the first part, presented before as a
separate paper (Niemczynowicz 1984b), described studies performed on conceptual
catchment, the secoGd part presented ...

Investigation Influence of Rainfall Movement Runoff Hydrograph Conceptual Catchment
2009/10/28
Work reported here consists of two parts: the first part describes studies
performed on a conceptual catchment, the second part, presented as a separate
paper, describes studies on real catchments i...
Analysis of Non-Linear Rainfall-Runoff Process
Analysis Non-Linear Rainfall-Runoff Process
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...
Effects of Spatially-Distributed Rainfall on Runoff for a Conceptual Catchment
Spatially-Distributed Rainfall Runoff Conceptual Catchment
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
Preliminary Considerations Runoff Modelling 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...

Large Scale Basins Negligible Slopes Generation of Runoff
2009/10/23
In the first of this two-paper series, the main mechanisms for generation of
runoff from rainfall in large basins with small to negligible slopes are analyzed
using available data from the Rio Negro...

Sub-Debris Thawing Ablation and Runoff Djankuat Glacier
2009/10/22
Superficial moraines grew in size during the entire 32-year-long period of direct
monitoring of water and ice balance of the Djankuat Glacier in the Caucasus.
The total area of debris cover on the g...
EFFECTS OF RAINFALL VARIABILITY ON SPATIAL ACCUMULATION OF PEAK RUNOFF AND EXCESS RUNOFF DEPTH: LITTLE WASHITA RIVER BASIN, OKLAHOMA, USA
surface runoff components runoff depth peak flow
2009/10/19
This paper demonstrates the spatial variability of surface runoff components, accumulated peak flow (Q a ) and excess runoff depth (R a ), in response to varying distribution of precipitation on a bas...
