Sand Extraction: 1. Introduction
Sand mining has led to deepening and widening of the Lake Poyang channel, the largest freshwater lake in China and a biodiversity reserve of exceptional importance, and to an increase in water discharge into the Yangtze River. This may have influenced the lowering of the lake’s water levels, which reached a historically low level in 2008.

Riverbed armoring and sediment exchange process in a sand–gravel bed
Upstream damming greatly altered the flow and sediment regime entering downstream reaches in the Middle Yangtze River, and the bed material in a sand–gravel bed reach coarsened continuously, which had a significant influence on the sediment transport and bed evolution. In order to study the riverbed armoring, the sediment exchange process (SEP) among bed material, bed load and suspended load
