虽然沉积物输送被认为是在集水区的空间尺度和一年的时间尺度上估计沉积物储存量的实用工具，但除非概念合理，否则没有可靠的工具可以得出有用的结果。它应与较大和较小的时间和空间尺度上的观测相一致。有人认为，通过景观中的给定点的泥沙测量是通量的测量。景观中不同地点和不同时间的通量差异使人们能够确定导致沉积物时空来源和汇的过程。
Although sediment delivery was conceived as a practical tool for estimating sediment storage at the spatial scale of catchments and the temporal scale of a year, no reliable tool can give useful results unless it is conceptually sound. It should be compatible with observations at larger and smaller temporal and spatial scales. It is argued that the measurements of sediment passing given points in the landscape are measurement of flux. The differences in flux, both at different points and at different times in the landscape, enable the identification of processes leading to spatial and temporal sources and sinks of sediment.
