Runoff Pattern and Peak Flows from Moving Block Rains Based on a Linear Time-Area Curve
Runoff Pattern Peak Flows Moving Block Rains Linear Time-Area Curve
2009/10/28
One of the most outstanding problems within urban drainage is to give a
statistically correct description of the runoff effect from areal and temporal
distributed rain storms. Due to the large numbe...
All scientific work performed so far to find the causality of the acidification of
many Norwegian open waters, have - considerably - increased our knowledge
about precipitation and soil water chemis...
Integrated Modelling of Runoff,Alkalinity,and pH on a Daily Basis
Integrated Modelling Runoff Alkalinity Daily Basis
2009/10/27
Based on the experience from runoff and groundwater recharge simulation a
model system has been developed for terrestrial, hydrochemical, and hydrological
simulations. The system emphasizes the role...
On Fitting Gamma Distrubution to Synthetic Runoff Hydrographs
Fitting Gamma Distrubution Synthetic Runoff Hydrographs
2009/10/27
Twelve methods of fitting the two-parameter gamma distribution to unit hydrographs
are evaluated using experimental data. Five of them are the methods of
moments (MOM), cumulants (MOC), maximum like...
Snowmelt Runoff Models for Operational Forecasts
Snowmelt Runoff Models Operational Forecasts
2009/10/27
Remote sensing is changing the approach in snowmelt runoff modelling. Instead
of a simulated snow cover, the areal extent of the real snow cover can be
periodically evaluated. Adaptation of depletio...
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...
This paper discusses results from a field study in a small East-Norwegian catchment.
The main object of the study was to separate the different runoff processes
in a small catchment. Direct measurem...
Simulation of Surface Runoff and Pipe Discharge from an Agricultural Soil in Nothern Sweden
Surface Runoff Pipe Discharge Agricultural Soil Nothern Sweden
2009/10/27
In order to test the ability of a physically based water and heat model to predict
surface runoff and pipe discharge, adaptations were made to an agricultural
field in the north of Sweden. A five-ye...
While snowmelt and rain-on-snow events have received considerable attention
in rural watersheds they have been largely ignored in urban hydrology, despite
the fact that they may result in severe flo...
Estimation of Catchment Rainfall Uncertainty and its Influence on Runoff Prediction
Catchment Rainfall Uncertainty Influence Runoff Prediction
2009/10/27
Interpolation of spatially varying point precipitation depths introduces uncertainties
in the estimated mean areal precipitation (MAP). This paper describes
a geostatistical approach - the Kriging m...
Progress in Developing an Operational Snowmelt-Runoff Forecast Model with Remote Sensing Input
Progress Operational Snowmelt-Runoff Forecast Model Remote Sensing Input
2009/10/27
In order to apply the snowmelt-runoff model (SRM) or any snowmelt model
operationally, a logical progression is required from utilization in the pure
simulation mode when all data are known to the p...
Application of Satellite Data to Monitoring Snow Cover and Runoff in Greenland
Satellite Data Snow Cover Runoff Greenland
2009/10/27
Based on NOAA-AVHRR satellite data and runoff records from one of the
major drainage basins in Western Greenland methods for monitoring snow
cover, snowpack water equivalent and runoff have been ela...
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...
Isotope studies in Swedish till basins indicate that stream stormflow is normally
dominated by pre-event water. The rapid response of the groundwater outflow
to infiltration may be explained by a la...
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...
