Knowra Sediment budget Sediment budget A sediment budget accounts for sediment entering, leaving, and accumulating within a defined area over a specified period. It helps explain changes in sediment storage and landform shape.
Sediment source : A location or process that supplies sediment to a transport system. Sources provide the material counted as inputs to the budget.
Drainage basin : An area of land that drains water and sediment to a common outlet. A basin provides a natural boundary for tracking sediment inputs and exports.
Coastal sediment budget : An accounting of sediment inputs, transfers, storage, and losses along a coastal reach. Coastal applications track beach and shoreline change through exchanges among neighboring compartments.
Coastal erosion : The removal of sediment or rock from a shoreline by waves, currents, wind, or other processes. Persistent sediment deficits can contribute to retreating shorelines.
Sediment transport : The movement of sediment by water, wind, ice, gravity, or human activity. Transport moves sediment between budget compartments and across their boundaries.
Sediment flux : The amount of sediment crossing a unit boundary per unit time. Flux expresses sediment transfers across budget boundaries.
River sediment budget : An accounting of sediment entering, moving through, and leaving a river reach or catchment. River budgets connect hillslope erosion, channel storage, and downstream export.
River aggradation : The raising of a riverbed or floodplain through net sediment deposition. An excess of sediment supply over transport capacity can produce aggradation.
Sediment storage : Sediment temporarily retained in a landform, basin, channel, or other part of a transport system. Stored material changes the budget even when it has not left the study area.
Sediment concentration : The mass of suspended sediment per volume of water in a sample or flow. Concentration measurements help estimate sediment carried by flowing water.
