The Hjulström curve, named after Filip Hjulström (1902–1982), is a graph used by hydrologists and geologists to determine whether a river will erode, transport, or deposit sediment. It was originally published in his doctoral thesis "Studies of the morphological activity of rivers as illustrated by the river Fyris. [1]" in 1935. The graph ...
This six-fold category characterisation is used in the Shepard and Young comparison chart and the Powers chart but the Krumbein chart has nine categories. Rounding of sediment particles can indicate the distance and time involved [citation needed] in the transportation of the sediment from the source area to where it is deposited.
Coastal sediment transport takes place in near-shore environments due to the motions of waves and currents. At the mouths of rivers, coastal sediment and fluvial sediment transport processes mesh to create river deltas. Coastal sediment transport results in the formation of characteristic coastal landforms such as beaches, barrier islands, and ...
In geography and geology, fluvial sediment processes or fluvial sediment transport are associated with rivers and streams and the deposits and landforms created by sediments. It can result in the formation of ripples and dunes , in fractal -shaped patterns of erosion, in complex patterns of natural river systems, and in the development of ...
Longshore drift – Sediment moved by the longshore current Deposition (sediment) – Geological process in which sediments are added to a landform or landmass; Coastal sediment supply – Transport of sediment to the beach environment; Sand dune stabilization – Coastal management practice; Submersion – Aspect of coastal erosion
Indications of waterborne debris and sediment transport. Defined river or stream bed and banks. The catchment area exceeds .25 square miles (0.65 km 2). USGS regression on the VHD data layer-oriented [definition needed] application on the probability of intermittent flow. The existence of aquatic organisms that require uninterrupted circulation.
The terms river morphology and its synonym stream morphology are used to describe the shapes of river channels and how they change in shape and direction over time. The morphology of a river channel is a function of a number of processes and environmental conditions, including the composition and erodibility of the bed and banks (e.g., sand, clay, bedrock); erosion comes from the power and ...
