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...

Abstracts for the symposium on the application of neural networks to the earth sciences
Donald A. Singer
2002, Open-File Report 2002-315
Artificial neural networks are a group of mathematical methods that attempt to mimic some of the processes in the human mind. Although the foundations for these ideas were laid as early as 1943 (McCulloch and Pitts, 1943), it wasn't until 1986 (Rumelhart and McClelland, 1986; Masters, 1995) that applications to...
