Hydromorphology

Work or the lifting of fill materials, generally intended to ensure the continuity of level for a structure.

Plain formed by the deposition of sediments from upstream erosion.

Study of the shape of rivers.

Branch of Hydraulics which mainly deals with the free surface flow of water in natural or artificial streams (e.g. canals). River hydraulics is necessary for the design, development and construction of hydraulic structures, such as dikes, sills and weirs.

Deposit of fine sediments made of rock particles and silt or clay. Siltation is a form of sedimentation with mud. Streams carry a few million cubic meters of sediment each year. Their deposit causes the silting of these rivers, canals, and bodies of water. This quite natural phenomenon is accentuated by a flat topography, low flows, erosion processes, as well as industrial and urban discharges.

Temporary or definitive man-made change in the layout of a watercourse by totally or partially diverting the water flow.

A type of river mouth characterised by heavy siltation at an elevation very close to that of the water surface and forming a natural marshy plain.

Action to remove soil or rubble to level or lower the soil.

A cutoff that occurs when two knees of the same meander meet. The cutoff then causes the abandonment of the meander to form a new channel.
