This animation shows a side view of an area where a river flows into a lake. As flowing water enters the lake, its velocity decreases. The water's ability to carry sediments also decreases. Sediments carried by the stream are deposited where the slowing water can no longer move them. The largest sediments are deposited near the shore.

    The results of this study can be compared to the more common temperate area studies as an indication of the usability of recreation water quality criteria for a broader range of conditions. More t responses were obtained from beachgoers on nine beaches. Water samples were collected every two hours at the nine beaches under study.

Analytical Data of Stream-Sediment and Heavy-Mineral Author: J. Gray. stream-sediment analysis (river-sediment analysis; drainage-sediment survey) A technique used in geochemical exploration and analysis, in which semimobile and immobile elements are measured from river or stream sediments, although under some circumstances highly mobile elements, e.g.

molybdenum, may be used. Anomalies in sediments are not always. Whereas regional stream sediment samples comprise material taken from points over a stream stretch of - m, sampling of streams around mine sites will, for obvious reasons of scale, be more focused.

The aim will be to demonstrate the spatial extent of any stream sediment contamination around the mine site and, 1. Geochemistry of sediments in the US from the NURE-HSSR database.
