K. L. Von Damm, James L. Bischoff, Robert J. Rosenbauer
1991, American Journal of Science (291) 977-1007
Experimental investigations confirm an increase of quartz solubility in sea-water relative to distilled water. Combination of the experimental data with published data, most of which related to distilled water, permitted construction of a database for calculating an equation that fits all the data. Application of the equation indicates a shallower...
Assessing the direct effects of streamflow on recreation: a literature review
Thomas C. Brown, Jonathan G. Taylor, Bo Shelby
1991, Journal of the American Water Resources Association (27) 979-989
A variety of methods have been used to learn about the relation between streamflow and recreation quality. Regardless of method, nearly all studies found a similar nonlinear relation of recreation to flow, with quality increasing with flow to a point, and then decreasing for further increases in flow. Points of...
