The dynamics of travertine dams
We present a simple, abstract model for travertine dam formation. The simulation uses a depth-averaged hydrodynamic code, coupled with an empirical precipitation model where surface-normal growth rate is proportional to local flow rate. The dynamics of the resulting formation, coarsening and migration (progradation) of crests is demonstrated and compared with field observations. The local self-...
متن کاملManaging the environmental impact of dams
In its final report, published in November 2000, the World Commission on Dams concluded that the benefits derived from large dams have made a significant contribution to human development. However, in many cases the environmental and social costs have been unnecessary and, by present standards, unacceptable. Often negative impacts arise as a consequence of lack of foresight and because dams are...
متن کاملRevisiting the homogenization of dammed rivers in the southeastern US
For some time, ecologists have attempted to make generalizations concerning how disturbances influence natural ecosystems, especially river systems. The existing literature suggests that dams homogenize the hydrologic variability of rivers. However, this might insinuate that dams affect river systems similarly despite a large gradient in natural hydrologic character. In order to evaluate patter...
متن کاملCorrection: Survival of Migrating Salmon Smolts in Large Rivers With and Without Dams
(2008) Fish invasions in the world's river systems: When natural processes are blurred by human activities. PLoS Biol 6(2): e28. The content of the published Dataset S1 was incorrect, due to a procedural error when the file was created. A corrected version of this file is now available. The figures and analysis presented elsewhere in the research article are not affected, as these were created ...
