The travel time for suspended load is controlled by the flow velocity and the distance to the basin outlet. Flow velocities do not change much downstream in a typical river system (Leopold, 1953) and typically range from 0.1 to several m/s. Hence, suspended load should be able to travel at least 10 to 100 km per day and the travel time for suspended sediment to traverse even the longest rivers in the world should be less than a season. Although some of the suspended load will be deposited in floodplains, the component of the suspended load that does not get sequestered in terrestrial depositional environments is delivered almost as fast as the water that it flows in. Bedload travels much more slowly. In mountain drainage basins, the velocity of individual bedload clasts is on the... [Pg.181]

Arid soils that lack diagnostic subsurface horizons are generally classified as Entisols, which fall into the azonal concept of Sibirtsev. These include many of the younger soils on floodplains, dunes, and erosional surfaces. In Soil Taxonomy, floodplain soils are mainly classified as... [Pg.43]

The Sava river basin is of great significance because of its outstanding biological and landscape diversity. It hosts a large complex of alluvial wetlands and large lowland forest complexes. The Sava is a unique example of a river where some of the floodplains are still intact, supporting both flood alleviation and biodiversity. [Pg.390]

Climate change will impact on water quality and quantity and hydromorphology and may thus remobilise historic pollutants from river bottom sediments and/or floodplain soils. However, the extent of this impact is still largely unclear and there is also a lack of feasible measures to mitigate the (potential) impacts. [Pg.419]

The western portion of the Thomson project area is classified as desert, with rainfall <250 mm/yr. The eastern portion is classified as grassland, with rainfall 250-500 mm/yr (Caritat Lech 2007). Summers are hot and dry, winters cool. Highly variable rainfall results in ephemeral streams, particularly in the west, and many of the creeks and rivers flow only during flood events, which can be significant events. The low-gradient, sinuous and anastomosing streams, creeks and rivers broaden to include flood plains often several kilometres wide. It is during these events that fine silts and clays from the upstream catchment are deposited on the floodplains. [Pg.233]

Catchment outlet sediments (similar to floodplain sediments in most cases) are sampled at two depths (0-10 cm below the surface as well as a 10 cm interval at a depth of between around 60 and 90 cm). [Pg.394]
