World Water Day Citizen scientists valuable information intermittent rivers
2019/11/22
On World Water Day and throughout the year, citizen scientists are providing valuable data on intermittently dry rivers in the Southwest United States.Trained citizen scientists are mapping three such...
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....
Hydrology of Rivers of the Cryolithic Zone in the U.S.S.R.
Hydrology of Rivers Cryolithic Zone U.S.S.R.
2009/10/26
The investigations provided the possibility to obtain a considerably better
knowledge of the water balance of river basins and the water exchange between
rivers and aquifers. The hydrological role o...
Animal Communities in Icelandic Rivers in Relation to Catchment Characteristics and Water Chemistry
Animal Communities Icelandic Rivers Catchment Characteristics Water Chemistry
2009/10/23
Catchment areas of Icelandic rivers are mostly barren or with little vegetation
cover in the highlands, but with heathland and mire vegetation in the lowlands.
Chemical composition and nutrient avai...
Life in Glacial and Alpine Rivers in Central Iceland in Relation to Physical and Chemical Parameters
Alpine Rivers Central Iceland Physical and Chemical Parameters
2009/10/23
The characteristics of stream and river ecosystems in arctic and alpine areas are
determined mainly by the relative contribution of glacial meltwater, snowmelt,
rainfall and groundwater. Each source...
