Sumner Griggs Heidel 1956 <ul><li>Numerous investigations of suspended‐sediment discharge have shown that an increase in stream flow usually is accompanied by an increase in sediment concentration. The sediment‐concentration peak during a rise may precede, coincide with, or follow the water‐discharge peak. Observations on the Bighorn River in Wyoming and Montana show a progressive lag in peak concentration behind peak flow. The lag is most apparent when a single storm produces a flood wave that starts many miles upstream from the sampling sections.</li></ul> application/pdf 10.1029/TR037i001p00056 en American Geophysical Union The progressive lag of sediment concentration with flood waves article
