BioScience, 1997 H umans have long been fascinated by the dynamism of free-flowing waters. Yet we have expended great effort to tame rivers for transportation, water supply, flood control, agriculture, and power generation. It is now recognized that harnessing of streams and rivers comes at great cost: Many rivers no longer support socially valued native species or ...

A discriminative method to flow regimes based on the flow resistance law
Shui kexue jinzhanUpper- and lower-flow regimes are formed under different conditions. To identify them is important for predicting mobile bed resistance. Based on the dimensionless resistance equation, a new discriminant function to flow regimes is deduced, which ...

Detection of changes in flow regime of rivers in Poland
Journal of Hydrology and Hydromechanics, 2018 The aim of this study is to detect changes in flow regime of rivers in Poland. On the basis of daily discharges recorded in 1951-2010 at 159 gauging stations located on 94 rivers regularities in the variability of the river flow characteristics in the ...
