Distribution and supply mechanisms of high uranium concentration in the rivers of Okinawa Island, Japan
uranium river Okinawa Island guideline value supply mechanism
2017/4/10
Uranium concentrations in the rivers of Okinawa Island, Japan were determined in this study. Most rivers in the
southwestern area of the island showed high U concentrations, the highest of which was ...
Towards a publicly available, map-based regional software tool to estimate unregulated daily streamflow at ungauged rivers
publicly available map-based regional software tool estimate unregulated daily streamflow ungauged rivers
2014/12/17
Streamflow information is critical for addressing any number of hydrologic problems. Often, streamflow information is needed at locations that are ungauged and, therefore, have no observations on whic...
Process dynamics and controls in two partially-confined rivers of upper Brahmaputra plain
River dynamics erosion-deposition Brahmaputra plain Anthropogenic influence Gai and Simen river
2014/11/12
This work quantifies channel processes in two partially-confined rivers of Upper Brahmaputra plain, namely, Gai and Simen and explores their controls. To achieve the objectives this study utilises RS-...
Dissolved Organic Matter-Complexed Iron in Two Rivers with Different Types of Soils in Watershed Area
Dissolved Organic Matter (DOM) Dissolved Humic Substances (DHS)
2013/3/11
Concentrations of dissolved organic matter (DOM), dissolved humic substances (DHS), and DOM-complexed Fe (DOM-Fe) in Yamakuni and Oita Rivers, Japan, of which headstream is near in location, flow pass...
A physical model for seismic noise generation from sediment transport in rivers
physical model seismic noise generation sediment transport in rivers
2014/4/8
Measuring sediment flux in rivers remains a significant problem in studies of landscape evolution. Recent studies suggest that observations of seismic noise near rivers can help provide such measureme...
Phytoplankton growth in three rivers: The role of meroplankton and the benthic retention hypothesis
Phytoplankton growth three rivers The role of meroplankton the benthic retention hypothesis
2014/4/8
We analyzed long-term (5–8 yr) hourly time series of chlorophyll (Chl) converted from fluorescence measurements in relation to discharge and light in three medium- to large-size rivers, where plankton...
Dynamic identifiability analysis of the transient storage model for solute transport in rivers
Dynamic identifiability analysis transient storage model solute transport
2009/12/4
The use of dynamic mathematical models to simulate the behaviour of environmental systems is common practice. However, the output of these models remains uncertain, despite their widespread use and lo...
To explain the formation of meanders, the author has synthesized relevant
knowledge and utilized basic physical principles of flowing turbulent
water and its interaction with the river bed.
Startin...
The Influence of Man's Activities in Rivers on Sediment Transport
Influence Man's Activities Sediment Transport
2009/10/29
An attempt to use old semicompiled data on turbidity, transport and deposition
of suspended material is carried out. The influence of different activities is
illustrated. The change of water chemist...
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...
Concentration data for the elements arsenic, cadmium, cobalt, molybdenum,
zinc, and uranium in eleven Norwegian rivers, determined by neutron activation
analysis, are presented. The mean values of t...
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...
Instrumental neutron activation analysis has been applied for the determination
of up to 40 elements in waters from eleven Norwegian rivers. In order to
represent the composition of an average river...
The Application of Radioactive Tracers for Determination of Bed-Load Transport in Alluvial Rivers
Radioactive Tracers Bed-Load Transport Alluvial Rivers
2009/10/28
Radioactive isotopes have been applied for determining the transport rate of
bed load in an alluvial river on the basis of: centroid velocity of the tracer
particles, size and material-transporting ...
Simulation of the Impact of Combined Sewer Overflow on Rivers
Simulation Impact Combined Sewer Overflow
2009/10/28
Combined sewer overflows can in some cases cause critical oxygen concentrations
in small rivers. The traditional design criteria for the overflow structures
is not specificly related to this effect....
