The deep water deposition means the deposition in the area where the water depth is larger than 30 meters, in which the major sediments are coarse sand and gravel. This kind of deposition is the relic deposition formed by the Pleistocene alluvial-lacustine deposition reworked under modern channel currents actions, and ususally the Holocene acummulation lack in the deep waters. The transitional zone deposition is the deposition between the low tidal level line and the 30 meters isobath, where the sediment types is changeable and the grain sizes are gradually coarsening from the low tidal line to the deep water area. This kind of deposition is developed by the deep water eroded sediments sorting under the transitional zone current action. The different types distributed along the isobath. The tidal flat deposition is the fine sediment deposition on the tidal flat which is flo sedimentation of the silty clay under the tidal flat dynamic action and ususally developed fluid mud on the lower tidal flat. The channel mouth deposition is the deposition in the channel mouth area. According to the sediment types, it includes sand deposition where there are coarse sediments supply and silt deposition where there are only fine sediments surpport.

峡道深水区沉积是指水深大于30米的峡道底部沉积，它以粗颗粒砂砾石沉积为特色，是现代峡道水动力对第四纪海退时发育的冲洪积和坡积物进行改造形成的蚀余沉积，全新世沉积地层往往缺失；峡道过渡带沉积是指水深介于低潮位线至30米水深线之间发育的峡道边坡沉积，该带沉积以沉积物类型多样为特色，自低潮位线至30米水深线，沉积物粒级逐渐变粗，由粉砂质粘土逐渐递变为中粗砂，是峡道深水区沉积物经多次分选沉积而发育的，基本平行于等深线分布的条带状沉积，在岸坡较陡岸段，过渡带下部可发育重力沉积；峡道潮滩沉积是指在低潮线与海岸线之间发育的细颗粒沉积，它是粘性细颗粒泥沙在潮滩动力作用下，发生动水絮凝沉积而形成的粉砂质粘土沉积，在低潮滩可发育浮泥；峡道口门区沉积则是在峡道汇入大海或海湾时，在峡道出口水流影响所及范围的沉积，根据峡道口门区供给泥沙的特性，峡道口门区沉积有粉砂质淤泥沉积和砂质沉积两种类型。

The strong sandstorm was caused by squall line activity of eastern Hexi Corridor in Apr. to Jun. that was cold front, majority is in May, four times strong sandstorm is accompanied by the squall line in seven times. It was explained that the squall line was suggested easily when the strong cold front moved east to Hexi Corridor where special canyon tube terrain was in, the strong sandstorm which was created by squall line activity have very strong paroxysm that often created serious disaster.

河西走廊东部的飑线活动造成的强沙尘暴出现在4~6月，均为冷锋型，其中5月居多，出现的7次强沙尘暴中有4次伴有飑线，说明5月份强冷锋东移经河西走廊特殊峡管地形时易诱发飑线，飑线活动造成的强沙尘暴爆发性强，往往造成严重灾情。
