cattle E. coli,GPS collars off-stream water best management practice
2013/9/9
Excessive levels of fecal bacteria are the leading cause of water quality impairment in Texas, and livestock with direct access to water bodies are potentially a significant source of these bacteria. ...
Simulation of land use–soil interactive effects on water and sediment yields at watershed scale
BMPs Brushcontrol Sediment Soil SWAT Watershed Water supply
2013/7/25
Influences of vegetation management on soil erosion have been extensively studied. However, interactive effects between land use and soil arepoorlydocumented in literature. Giventhe importance o...
Effects of Aquatic Vegetation on Fish Assemblages in a Freshwater River of Taihu Lake Basin, East China
Macrophyte Fish Assemblages Emerged Plant Floating-Leaved Plant pH Transparency
2013/3/18
Distribution characteristics of fish assemblages and environmental variation in emerged plant, floating-leaved plant and blank habitats were studied. Emergent plant habitat supported the greatest fish...
Relative Depth Effects on Corrugated Culvert Roughness
Culverts Fish Passage Low Flows Roughness Manning’s Equation
2013/3/19
Fish passage is important to the overall health of an ecosystem. Therefore, it is important to be able to accurately predict flow conditions within a stream crossing for high and low flow periods. Thi...

Derivation of climate elasticity of runoff to assess the effects of climate change on annual runoff
climate runoff to assess annual runoff
2013/7/25
Climate elasticity of runoff is an important indicator for evaluating the effects ofclimate change on runoff. Consequently, this paper proposes an analytical derivation ofclimate elasticity. Based on ...
Pool Effects on Longitudinal Dispersion in Streams and Rivers
Pool Effects Solute Transport Longitudinal Dispersion Transient Storage Open Channel
2013/3/21
Surface storage (pools, pockets, and stagnant areas caused by woody debris, bars etc) is very important to solute transport in streams as it attenuates the peak of a spill but releases the solute back...
