Water Balance. Sediment Yield.
The action of water on slopes in dry lands can escort to sediment transport processes such as wet erosion, overland flow transport, riling, gullying and mass movement particularly debris flows…
usual concepts employed to study landscape morphology do not essentially hold for dry land environments, where extreme proceedings are responsible for most erosion and sediment transport.
The finest descriptions are from areas of vertical soils in the waterway Country of inland Australia, where they arise widely. They have also been explained on 'tabra' soils in the Sudan. What these areas have in common is the establishment of the soil outside into hummocky landscape. In the Australian examples this is due to gilgai, in the Sudanese example to differential compaction of the soil on climate 0 channel links can be developed per square kilometre.
The hummocky surface makes flow to focus close by in lower areas where its greater depth causes it to be faster and livelier. This deliberation of flow causes waterways to form linking the depressions. Other features contributing to conduits formation are that slumps are more often covered than mounds, and as a consequence the floodplain there is often more cracked and eroded.
It would seem as purely phenomena for land area or at least similar channels haven't yet been explained from other surroundings. Amongst other things, a lack of foliage seems essential to enable over bank flow to cut conduits where it wouldn't otherwise have enough energy.
What is their protection possibility They have not been depicted in the rock record. ...
