Changes in streamflow and sediment discharge and the response to human activities in the middle reaches of the Yellow River
Changes in streamflow sediment discharge
2011/1/7
The changes in streamflow and sediment discharge in the middle reaches of the Yellow River are a focus. In this paper, based on the precipitation, streamflow and sediment discharge series data (1950–2...
The contribution of groundwater discharge to the overall water budget of two typical Boreal lakes in Alberta/Canada estimated from a radon mass balance
groundwater discharge overall water budget typical Boreal lakes radon mass balance
2010/2/1
Radon-222, a naturally-occurring radioisotope with a half-life of 3.8 days, was used to estimate groundwater discharge to small lakes in wetland-dominated basins in the vicinity of Fort McMurray, Cana...
Development of a discharge equation for side weirs using artificial neural networks
discharge equation side weirs artificial neural networks
2009/12/4
Flow over a side weir is one of the more complex flows to simulate in one-dimensional unsteady flow analysis. Various experiments have been applied, but no agreement is apparent in the literature abou...
AN IMPLEMENTATION OF STAGE-FALL-DISCHARGE RELATIONSHIP ON DIGITAL COMPUTERS
IMPLEMENTATION STAGE-FALL-DISCHARGE RELATIONSHIP DIGITAL COMPUTERS
2009/10/30
The stage-discharge relation is defined by the complex interaction of channel
characteristics, including area, shape, slope, and roughness of the cross-section.
The combination of these effects has ...

GROUND-WATER DISCHARGE BALTIC SEA METHODS FOR ESTIMATING IT
2009/10/29
The methods for quantitatively estimating ground-water discharge to the
Baltic Sea and the possibilities of applying these methods to investigations
of the role of ground water in the water and salt...
Groundwater Discharge through Springs with Well-Defined Outlets A Case Study from Jeløya–Moss,S. Norway
Groundwater Discharge Well-Defined Outlets Jelø ya–Moss
2009/10/28
From the area of JeLya - Moss, southern Norway, five springs draining
fissured-rock aquifers, and one artesian well draining confined water from a
sand and gravel aquifer were studied during the yea...
Discharge Measurements by a New-Formed Relative Salt-Dilution Method in Small Turbulent Streams
Discharge Measurements New-Formed Relative Salt-Dilution Method Turbulent Streams
2009/10/28
Water discharges in small turbulent streams are determined by injecting concentrated
salt solutions at constant feed-rate and measuring the dilution level
downstream by conductivity readings in situ...

Glacial-Hydrological Investigations Vernagtferner Glacier Discharge Model
2009/10/28
The report gives a review on the glacial-hydrological work carried out since
1974 in the project "Runoff within and from glaciers" of Sonderforschungsbereich
81 of the Technical University Munich wi...
Quantitative and Qualitative Characteristics of Urban Discharge to Small River Basins in the South West of Sweden
Qualitative Characteristics Urban Discharge Small River Basins
2009/10/28
The paper deals with the qualitative and quantitative characteristics of urban
discharge. Ratios for urban discharge and recipient flow during different time
intervals are presented and discussed. T...
Estimation of Combined Sewer Overflow Discharge From the City of Malmö
Estimation Combined Sewer Overflow Discharge City of Malmö
2009/10/28
The function of combined sewer overflows (CSO) from both a quantitative
and a qualitative point of view is often little known in the Nordic communities.
Since large pollution loads are discharged fr...

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...
