aggradationの例文

• Mainstream aggradation also formed numerous bars, further establishing braided morphology.
• Aggradation occurs when there is a supply of sediment and changes in water flow.
• In 1938, the pier was last moved further north due to proceeding aggradation.
• This had resulted in measured aggradation of the river bottom of as much as 5 metres.
• "' Aggradation "'in geology is the building up of sediment in unoccupied spaces.
• Aggradational environments are often undergoing slow subsidence which balances the increase in land surface elevation due to aggradation.
• In addition, the regional environment will determine how change in sediment and precipitation will drive river incision and aggradation.
• Aggradation at the mouth of the stream once partly dammed Buffalo Creek, resulting in as much as of fill.
• After the first stage of aggradation and sediment transport, the Kobuk began a new phase of erosion and landform development.
• Near the coast it occurs in brackish water and inland in fens and raised bogs or aggradation zones of standing waters.
• Widespread bed aggradation forced flow through floodplain channels, depositing additional sediment in the side channels of the Elwha river floodplain.
• Conifer resin has no aggradation character because it consists of derivatives of diterpenes ( resin part ) and monoterpenes ( part turpentine ).
• Terraces along the river will record the cyclic changes, where glacial and interglacial time periods are associated with either incision or aggradation.
• Aggradation can be caused by changes in climate, land use, and geologic activity, such as volcanic eruption, earthquakes, and faulting.
• The morphology of an alluvial river reach is controlled by a combination of sediment supply, substrate composition, discharge, vegetation, and bed aggradation.
• The rapid aggradation of sediments from the delta produced a steep delta slope, which may have resulted in occasional debris flows that formed the turbides.
• If aggradation continues to occur in the main channel, this will make levee overtopping more likely again, and the levees can continue to build up.
• Branney et al . suggest that the chemical changes are recording progressive aggradation at the base of the flow from an eruption whose composition changes with time.
• In times of drier climate, wind dominates and blows a lot of sediment into a weaker fluvial system, leading to aggradation and floodplain re-distribution.
• Depending on the nature of the river bed, strong movements of sediment could lead to ements to aggradation, thus covering the chain with gravel and stones.
