In 1972 Ackers and White (Refs 24 and 25) proposed a new sediment transport theory and tested the theory against f1ume data. This data consisted of about 1000 measurements with particle sizes in the range 0.04 < D(mm) < 5 and sediment specific gravities in the range 1.07 < s < 2.65. Subsequent phases in this investigation have included (i) the acquisition of about 270 field measurements of transport rates from the literature and (ii) the testing of all commonly used sediment transport theories against this extended range of data. These two phases are the subject of the present report. The report also includes a proposed modification to one of the existing stochastic theories which significantly improves its performance. Volume 1 describes the sediment transport theories and indicates in each case how the theories have been used in the present investigation. Where the theories include graphical solutions, analytical equiva1ents have been worked out to facilitate the use of a digital computer for the analysis. The limitations of the theories are indicated wherever the original authors have given specific recommendations. Volume 2 describes and classifies the data used for comparative purposes. It defines the criteria on which the comparison between observed and calculated transport rates are based and presents the results provided by the theories described in Volume 1. The problems of graded sediments are discussed and illustrated using gravel river data. A modification to the Bishop, Simons and Richardson theory is proposed together with suggestions for further refinements which could be introduced at a later date. The performance of the various theories is compared and recommendations are made regarding their usage.
