The dependence of estuarine turbidity on tidal intrusion length, tidal range and residence time
R.J. Uncles, J.A. Stephens, R. E. Smith
2002, Continental Shelf Research (22) 1835-1856
It is shown that there is a marked tendency for long, strongly tidal estuaries to have greater suspended particulate matter (SPM) concentrations within their high-turbidity regions than shorter estuaries with comparable tidal ranges at their mouths, or weakly tidal estuaries. Using consistently derived data from 44 estuaries in Europe and...
