A river delta is a low-lying plain or landform that occurs at the mouth of a river near where it flows into an ocean or another larger body of water. Deltas' greatest importance to human activities, fish and wildlife lay in their characteristic highly fertile soil and dense, diverse vegeta...

Delta, low-lying plain that is composed of stream-borne sediments deposited by a river at its mouth. A brief treatment of deltas follows. For full treatment, see river: Deltas. One of the first texts to describe deltas was History, written during the 5th
Sediment balance at river mouths—a physical basis of delta dynamics—is considered. The specific features of relationships between sediment balance components at a mouth of a river are established for a stable, rising, or dropping sea level. The development of the delta of the Chilia branch at...
The Luanhe River Delta is a delta plain built ' up by the action of rivers and sea waves together.Owing to the migrations of the distributary region sincethe Holocene Period five secondary delta depositional masses were formed during the Early Holocene, the Middle Holocene, the early historical...
of the topography, a model has to in- clude the essential processes responsible for the changes of the land- scape. In Geology the formation of river deltas and braided river streams has been studied since a long time describing the schematic processes for the formation of deltaic dis...
Swamp, type of wetland ecosystem characterized by mineral soils with poor drainage and by plant life dominated by trees. The latter characteristic distinguishes a swamp from a marsh. Swamps are found throughout the world and are often in low areas associ
Braided river delta that braided river systems prograde into an inland lake is very abundant in the Lower Jurassic Sangonghe Formation in the Yining Basin,Xinjiang. Their characters are distinct and significantly different from the other types of deltas. The braided river deltas are deposited by ...
Meanwhile, the high concentration of CO2 in the atmosphere during the Middle and Later Pinghu periods caused a sharp increase of erosion. Enormous sediments provided by the source areas were transported into the Xihu Depression, which accelerated the progradation of braided river delta into the sea...
