Introduction [2] Sediment flux measurements from rivers are important for evaluating terrestrial organic and inorganic material export, landscape denudation, geomorphic change, habitat and water quality, and inputs to reservoir and coastal systems. Rates of sediment discharge are related to the sources, transport and storage of sediment within a watershed, which are in turn related to.

    With 36 years of experience in sediment data collection and sediment discharge computation,  Freeman Hydrologic Data Services  is able to compute records based on sediment samples and streamflow data, and use surrogate data if available. Hydrologic instrument and equipment evaluation. The records contain streamflow data, stage and contents data for lakes and reservoirs, and water-quality data for surface water. The following sections of the introductory text are presented to provide users with a more detailed explanation of how the hydrologic data in this report were collected, analyzed, computed, and arranged for presentation.

introduction. Collection, computation, and publication. The drawing of a temporal concentration curve fram individual values of concentration is the first ste,p in the computation of sediment discharge. It is not only useful to study the variations of concentration with time but to estimate concentration graphs for missing periods or for inadequately sam­ pIed periods.

For example, Section A of Book 3 (Applications of Hydraulics) pertains to surface water. The chapter, the unit of publication, is limited to a narrow field of subject matter. This format permits flexibility in revision and publication as the need arises.

For periods when no samples were collected, daily discharges of suspended sediment were estimated on the basis of water discharge, sediment concentrations measured immediately before and after the periods, and suspended-sediment loads for other periods of similar discharge.

Methods used in the computation of sediment records are described in the Techniques of Water-Resources Investigations (TWRI) Book. The annual discharges for the years 19 inclusive in table 3, column 2, can be used to define a frequency curve. The curve can be cumulated from the high end or from the low end, depending on whether the data are arrayed from the high end or from the low end.
