Satellite Potentials in Snowcover Monitoring and Runoff Prediction
Satellite Potentials Snowcover Monitoring Runoff Prediction
2009/10/29
Earth resources satellites have provided a means for the timely, efficient, and
accurate monitoring of watershed snowcovered area. Several techniques are
available for analysing the data ranging fro...
Estimation of Parameters of a Uniformly Nonlinear Surface Runoff Model
Estimation of Parameters Uniformly Nonlinear Surface Runoff Model
2009/10/29
The surface runoff model, based on the concept of uniform nonlinearity
(Dooge 1967), has three parameters. It is shown that these parameters can be
estimated from the informaion that can be easily o...
Management of Urban Runoff and Wastewater in the Oslofjord Area
Urban Runoff Wastewater Oslofjord Area
2009/10/29
To alleviate the pollution in the Oslofjord region it is planned to transport wastewater
to a central treatment plant by a 35 km tunnel system. The objective of the
study was to analyze the conseque...
The Physiographic Influence on Recession Runoff in Small Norwegian Rivers
Physiographic Influence Recession Runoff Small Norwegian Rivers
2009/10/29
This paper presents a statistical correlation procedure to predict a master
depletion curve by use of basin characteristics and the specific storage of
water available for runoff at a particular rec...
The Watershed Influence on Storm Runoff in Small Norwegian Rivers
Watershed Influence Storm Runoff Small Norwegian Rivers
2009/10/29
A procedure to isolate and investigate the watershed influence on storm
runoff is presented. It offers an opportunity to study also the change in
influence of particular watershed characteristics by...
Chemical Budgets and Chemical Quality of Snow and Runoff During Spring Snowmelt
Chemical Budgets Chemical Quality Spring Snowmelt
2009/10/28
In connection with water acidification and the subsequent disappearance of
fish populations and also massive fish kills during spring floods, particular
interest has been focused upon the fate and e...
Application of a Snowmelt-Runoff Model Using Landsat Data
Application Snowmelt-Runoff Model Landsat Data
2009/10/28
The snowmelt-runoff model developed by Martinec (1975) has been used to
simulate daily streamflow on the 228 km2 Dinwoody Creek basin in Wyoming,
U.S.A. using snowcover extent from Landsat and conve...
Five different rainfall - runoff models including three sophisticated conceptual
models (Sacramento, Stanford and Monash Models), a simple conceptual
model (Boughton Model) and a black-box or purely...
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...
Relationships between Precipitation Chemistry,Hydrology,and Runoff Acidity
Relationships Precipitation Chemistry Hydrology Runoff Acidity
2009/10/28
High precipitation amounts of strongly varying ionic composition make the
western parts of southern Norway well-suited for studies of certain relationships
between precipitation chemistry, hydrology...
Isotope Input into Runoff Systems from Melting Snow Covers
Isotope Input Runoff Systems Melting Snow Covers
2009/10/28
Stable environmental isotope techniques contribute to reasonable separations
of the direct runoff component in snowmelt hydrographs. For the separation
procedure, the actual isotope input from snow ...
Results of runoff simulations from various basins using a snowmelt runoff
model were analyzed in order to predict the accuracy of simulations in future
applications of the model. It was found that t...

2009/10/28
600 mm of artificial, "unpolluted" precipitation with a chemical composition
of assumed preindustrial quality ((HC] = 9 peql-I. ISO,] = 11 peql-') was
sprayed on a "mini-catchment" (98 m2) over a pe...
