The total amount of eroded material that passes a downstream point. Sediment yield can be expressed as a total mass of sediment moving past a certain point (Kg) or as a mass per unit area (Kg/m2, Kg/ha, etc.).
The amount of sediment removed from a watershed over a specified period of time and area, usually expressed as tons, acre-feet, or cubic yards of sediment per unit of drainage area per year.
The total sediment outflow from a watershed or a drainage area at a point of reference and in a specified time period. This outflow is equal to the sediment discharge from the drainage area.
The quantity of sediment, measured in dry weight or by volume, transported through a stream cross-section in a given time, e.g., tons/hour/acre. Sediment discharge consists of both suspended and bedload sediments (Schwartz et al. 1976, sediment discharge).
The sediment discharge from a unit of drainage area, generally expressed in tons per square mile of acre.
The quantity of sediment arriving at a specific location.
1. Total quantity of sediment moving out of a watershed in a given time interval, expressed in units of mass per unit time. 2. Total sediment discharge from a watershed relative to the watershed area, expressed in units of mass per unit time per unit area.
