Abstract
Grain-size variation of sediments in different environments of the coastal zone between Wadi Al-Fagh and Wadi Al-Qunfidah, eastern Red Sea were studied. The sediments distribution reflects short-lived flood flow patterns in the wadis. The remarkable changes in the texture characteristics of sediments of the northern wadis are considered to be due to the rainfall increase to the south. The terrigenous sediments from the wadis are mixed with locally produced carbonate in varying proportions in the beach and littoral zones. Such mixing and subsequent reworking by the nearshore processes result in the observed variation in texture.
