Progradation of relatively steep delta front (1-10°) produces a type of bed geometry called a clino as long as mDelta front as long as esetsTopsetForesetToesetBottomsetProdelta (sub-wave base) generally resembles fine-grained offshore faciesSlumps may occur due to steeper prodelta slopes in addition to rapid sedimentation rateDelta front sediments occur as coarsening-upward succession over prodeltaMay have characteristics of wave or tide influenceProdeltaDelta FrontDelta FrontPDelta PlainTransgressive lag

By definition, fluvial influence is important in deltasWaves or tides can also rework delta plain depositsFundamental sedimentological unit of a delta is the distributary mouth bar, as long as med where sediment is rapidly deposited after rivers enters basinTraction deposition with significant contribution from suspension settlingClimbing ripplesHigh sedimentation rates during river flood events
