Theoretical basis and fundamental equations of a newly developed method of
estimation of suspended sediment transport rate is presented. The new theory is based on turbulence energy concept and in particular the idea that "suspended sediment concentration at any depth above the stream bed is proportional to the total turbulent energy production of the flow at the same level". The proposed equation is simple and suitable for engineering
application. It involves a small number of
easily measurable well-known hydraulic
. ¬
and sediment parameters. The new
formula has been tested against a wide range of hydraulic and sediment transport data from both natural channels and laboratory flumes. The test results have indicated that despite its simple structure the developed equation shows very satisfactory predictions. In comparison with the well established suspended load predictors the proposed equation appears to have better accuracy.
