Recent Hypolimnetic Sediment in Lake Gjersjöen,a Eutrophicated Lake in SE Norway
Hypolimnetic Sediment Lake Gjersjö en Eutrophicated Lake SE Norway
2009/10/29
During the last decades Lake Gjersjaen has developed from an oligotrophic state
to a level of high eutrophy. The present state is characterized by an intense
primary production in the trophogenic zo...
A Sediment Transport Model for Straight Alluvial Channels
Sediment Transport Model Straight Alluvial Channels
2009/10/29
The paper presents a simple mathematical model for sediment transport in
straight alluvial channels. The model, which is based on physical ideas related to
those introduced by Bagnold (1954), was or...
In connection with the 50th anniversary of Aarhus University, 11 September,
1978, brigadier R.A. Bagnold, F.R.S., was conferred the honorary degree of
Doctor of Science. The present paper is the man...
A Modified Sediment Transport Model for Natural Streams
Modified Sediment Transport Model Natural Streams
2009/10/28
In an earlier investigation of the behaviour of tracer particles for determination
of bed load transport in an alluvial stream (Thomsen 1080), specific
records were taken of the particle velocities ...
River Flow with Excessive Suspended Sediment Load
River Flow Excessive Suspended Sediment Load
2009/10/27
River flows with high volume concentrations (20-50 %) of silty sediments generally
imply that the mixture has non-Newtonian properties. In this study, the
rheological behaviour of mixtures with soli...
Effect of Texture,Rainfall and Slope on Rainfall Interrill Sediment Transport
Texture Rainfall Slope Interrill Sediment Transport
2009/10/26
Experiments were conducted with rainfall intensities of 45.0 and 140.0 mmlhr
at slopes of 2, 9 and 20 per cent to separate the dominant effect of rainfall
intensity on sediment transport capacity. T...
Seasonal Variations in Suspended Sediment Yield in the Baltic Sea Drainage Basin
Seasonal Variations Suspended Sediment Yield Drainage Basin
2009/10/26
The aim of this article is to describe the seasonal fluctuations of suspended
sediment yield in the Baltic Sea drainage basin and to quantify the monthly
inflow of suspended sediment to the Baltic. ...
Suspended Sediment Yield in the Baltic Drainage Basin
Sediment Yield Baltic Drainage Basin
2009/10/26
The aim of this paper is to quantify the spatial distribution of suspended sediment
yield in the Baltic Sea drainage basin, and to quantify the suspended
sediment inflow to the Baltic. The sediment ...
The Effect of River-Ice Break-Up on Suspended Sediment and Select Trace-Element Fluxes
River-Ice Break-Up Suspended Sediment Trace-Element Fluxes
2009/10/26
Ice break-up on northern rivers presents a unique research challenge because of
its dynamic nature and complexity of physical, chemical and biological processes.
Rapidly moving ice, ice jamming, flo...
Sediment Fabric and Anisotropy of Hydraulic Conductivity in Sandy Till,Wisconsin, U.S.A.
Sediment Fabric Anisotropy of Hydraulic Conductivity
2009/10/23
The orientation of macroscopic and n~icroscopic particles in silty, sandy basal
till appears to have little effect on aquifer anisotropy. The orientation of 108
elongate pebble and cobble-sized part...
Comparison of Sediment Rating Curves Developed on Load and on Concentration
Sediment Rating Curves Load Concentration
2009/10/23
A sediment rating curve developed as a lincar regression on logged values
which is back-transformed must be corrected for the bias introduced by the log
transformation. This article shows that the v...
Sediment Bound Contaminants in a Remote Northern Delta
Sediment Bound Contaminants Remote Northern Delta
2009/10/23
Deltas of major rivers are among the most productive and environmentally sensitive
components of riverine systems in cold regions, and are of great hydrological
and ecological importance. Much of th...
Assessment of Variability in Fluvial Sediment Transfers in Kärkevagge (N-Sweden) during the last 50 Years
Assessment of Variability Fluvial Sediment Transfers Kä rkevagge
2009/10/23
The Kiirkevagge (Abisko area, Northern Sweden) represents a focus research
basin concerning geomorphic processes and sediment budgets for the last 50
years. Different geomorphic process studies prov...
Suspended Sediment Transport from the Dokriani Glacier in the Garhwal Himalayas
Suspended Sediment Transport Dokriani Glacier Garhwal Himalayas
2009/10/22
Estimation of sediment load from glacierized basins is very important for planning,
designing, installation and operation of hydro-power projects, including
management of reservoirs. In the present ...
Hydraulic Modelling of Suspended Sediment Deposition in an Inundated Floodplain of the Nemunas Delta
Hydraulic Modelling Suspended Sediment Deposition Nemunas Delta
2009/10/22
Floods of meadows in the delta of the river Nemunas contribute to the deposition
and retention of sediments and nutrient that would otherwise deposit in the
Curonian Lagoon. In grassland area of the...
