A PRELIMINARY ANALYSIS OF SEDIMENTARY CHARACTERISTICS OF HANGZHOU BAY
杭州湾潮滩沉积特性初步分析

Hangzhou Bay is a typical strong tidal estuary sandbeach with an average grain size of 0.25mm, but coarser in the north and thinner in the south. The northern bank has retreated gradually and the southern one has widened through siltation for thousand years. So the northern bank is better fitted for developing waterway if breakwater is built, southern bank is more suitable for agriculture development if the soil condition is improved. This article describes the composition of sediment, the structural dynamics and distribution patterns, offering valuable reference for the better use of the bay.
