Urbanization of a Watershed and Historical Changes in a Stream Fish Assemblage (1990) data to evaluate the hypothesis that long-term, low-intensity urbanization affects a warmwater stream fish assemblage in ways usually attributed to ...

At lower baseflow conditions, several net neutral or gaining reaches also showed a 5-15% tracer mass loss, indicating that gross gain and loss operate concurrently in these reaches. We use these water balance fluxes to indicate one scale of stream - ground water exchange, and we compare ...
Streambeds are critical hydrological interfaces: their physical properties regulate the rate, timing, and location of fluxes between aquifers and streams. Streambed vertical hydraulic conductivity () is a key parameter in watershed models, so understanding its spatial variability and uncertainty is ...
s waters from ocean to atmosphere to land and back to ocean. The cycle can be thought of as a huge water pump that is powered by solar radiation (energy from the sun) and by gravity. The hydrologic cycle is a global system, and every molecule of water on Earth is a part of the ...
The percentage of added SO4 leached to the stream increased to approximately 65% by the end of 1995. Thus, soils along base-flow paths adsorbed about 35% of the added SO4 in 1995. 3. Aluminum concentrations in WB have increased from a pre-manipulation maximum of 10 µmole/L at high...
Urea in the waters of Lake Kinneret (Sea of Galilee) Urea concentrations measured in the pelagic waters of Lake Kinneret over a 12-month period varied from undetectable to maximum values of 80 and 150 渭 g N liter-1, with a seasonal pattern of fluctuation. Although urea is not a major ...
p xml:lang="en"&Lake-stream networks dominate much of northern Canada. This study explores the hydrological characteristics of an outlet stream from a headwater lake in the Northwest Territories of Canada. Flow hydrographs indicated that stream flow was maximal in most of the cross sections during...
Stream ecosystemsBenthic invertebratesFunctional feeding groupsA study was undertaken to define the benthic populations, the environmental‐ecological variability and trophic aspects according to the functional feeding groups in the upper reaches of the Nera River, a tributary of the Tiber, in central ...
