aggradation
alluviation

In 1938, the pier was last moved further north due to proceeding aggradation.

The method can also be extended to aggradation deposits of interglacial age.

The simple association of degradation and aggradation of beaches with wave type needs some modification.

It is the opposite of aggradation.

But by far the most refined technique for the interpretation of aggradation deposits is that of pollen analysis.

This had resulted in measured aggradation of the river bottom of as much as 5 metres.

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.

Some deltas are virtually continuations of the aggradation type of river floodplain (see Chapter 9).

The outstanding example of such aggradation in the British Isles is provided by the Fenland.

By such a refined technique as this it is possible to know what was happening in various aggradation deposits at various periods of Post-glacial history.

Aggradational environments are often undergoing slow subsidence which balances the increase in land surface elevation due to aggradation.

Settlement and its surroundings are located on the plain aggradation below sea level, as most of the Astrakhan Oblast.

As a result aggradation took place and the surfaces of such aggradations, now dissected by later erosion, may remain in the form of terraces.

Aggradation occurs in areas in which the supply of sediment is greater than the amount of material that the system is able to transport.

Aggradation can be caused by changes in climate, land use, and geologic activity, such as volcanic eruption, earthquakes, and faulting.

An outer zone or aggradation zone which extends beyond the pediment and is a zone of deposition.

Terraces along the river will record the cyclic changes, where glacial and interglacial time periods are associated with either incision or aggradation.

In addition, the regional environment will determine how change in sediment and precipitation will drive river incision and aggradation.

This aggradation of soil is the result of aeolian or fluvial sedimentation and/or peat formation.

Earlier in history this connection was used to ship goods into the small harbour, which still exists but has become less accessible due to city developments and aggradation.

The ages of incision and flooding (aggradation) can have different interpretations for each fluvial system, where each region may respond independently to external variation.

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.

After this there was a steady decline in irrigation due to "droughts, sedimentation, aggradation of the main channel, salinization, seepage and waterlogging".

The morphology of an alluvial river reach is controlled by a combination of sediment supply, substrate composition, discharge, vegetation, and bed aggradation.

Such detailed analyses of aggradation deposits as this are not possible by purely geomorphological methods, but require considerations of stratigraphy and especially of fossils.

It is a water-assisted transport in a basically vertical direction, as compared to alluviation, the horizontal running water transfer.

The burial of Sybaris about 2500 years ago more likely resulted from natural processes such as fluvial overbank alluviation.

The third largest lake in Hungary, Lake Velence is a steppe lake in an advanced stage of alluviation.

It also includes neighborhoods Lescaut and Alluviation, as well as towns of Velykaya Koreniha and Malaya Koreniha.

However, it appears that major alluviation and incision events could be ascribed to the factors associated with climatic processes such as strengthening or weakening of monsoonal precipitation and related fluvial discharge.

In most of the Great Basin region, Late Pleistocene and Holocene alluviation has effectively buried and sealed earlier Pleistocene sediments and possible evidence of pre-Clovis cultures.
