Modelling ecological flow regime: an example from the Tennessee and Cumberland River basins
Predictive equations were developed for 19 ecologically relevant streamflow characteristics within five major groups of flow variables (magnitude, ratio, frequency, variability, and date) for use in the Tennessee and Cumberland River basins using stepbackward regression. Basin characteristics explain 50% or more of the variation for 12 of the 19...
Knight, Rodney R.; Gain, W. Scott; Wolfe, William J. Regression models of ecological streamflow characteristics in the Cumberland and Tennessee River Valleys
Predictive equations were developed using stepbackward regression for 19 ecologically relevant streamflow characteristics grouped in five major classes (magnitude, ratio, frequency, variability, and date) for use in the Tennessee and Cumberland River watersheds. Basin characteristics explain 50 percent or more of the variation for 10 of the 19...

Tree-regeneration and mortality patterns and hydrologic change in a forested karst wetland--Sinking Pond, Arnold Air Force Base, Tennessee
Multiple lines of evidence point to climate change as the driving factor suppressing tree regeneration since 1970 in Sinking Pond, a 35-hectare seasonally flooded karst depression located on Arnold Air Force Base near Manchester, Tennessee. Annual censuses of 162-193 seedling plots from 1997 through 2001 demonstrate that the critical stage for...

Time-of-travel of solutes in the Trinity River from Dallas to Trinidad, Texas, May and August 1987
The U.S. Geological Survey (USGS), in cooperation with the city of Dallas, conducted a study of the time of travel of solutes during moderate flow conditions in a reach of the Trinity River from the outfall of the Dallas Central Wastewater Treatment Plant (DCWTP) to the USGS streamflow-gaging station 08062700, Trinity River at Trinidad, in May and...

Physical and chemical water-quality data and nitrogen and phosphorus yields for 29 sites sampled in two synoptic surveys of streams within the Lewisville Lake watershed are presented in this report. The two synoptic surveys were conducted in March 1984 and March 1985, as a reconnaissance and assessment of water quality and nitrogen and phosphorus yields throughout the watershed. This work was cooperatively funded by the city of Dallas and the U.S. Geological Survey (USGS) as part of a hydrologic study to quantify nonpoint nutrient loads to Lewisville Lake.
