Sediment formation and quantitative distribution of its components along the shores of large reservoirs
Conclusions 1. All fractions resulting from erosion of the lake shore formations participate in creation of the offshore deposits. 2. In order to express the extent of sediment accumulation, masses (weight units), but not volumes, are to be used. 3. With gently sloping banks, the regularity of mass distribution of a fraction in a cross section is characterized by Pearson's curve, type I. Mass distribution of deposits and change of their granular composition in each interval of depth or distance is expressed by the sum of products of the mass and the probability value of each fraction (P1·p+P2·p+...Pn·p). The thickness and the length of the sediment train, the width of the accumulative part of the bar, and the slopes of its outer edge depend on the nature of changes in these sums. With steep bank this distribution process becomes complicated because of displacement under the natural slope conditions of that portion of sediment mass which deposits upon the reaches of a steep slope.
