Silt Charge of Water in the River Sluch: Dynamics on Length and in Time
https://journals.bilpubgroup.com/index.php/hsme/article/view/4677
<p>Change silt charge of water in the rivers can negatively be reflected in throughput the rivers beds, stability of coast, change of river structures, dis appearance of boggy places, etc. In work questions of variability silt charge waters in the river Sluch in time and on length of the river are considered. It is revealed that in time average and maximal silt charge waters decrease. While on length of the river change silt charge waters is shown not precise ly, similar on some increase silt charge waters to a mouth of the river. The researches led by the factorial analysis and graphic-analytical method on the basis of long-term materials of measurement of charges of water have shown that, on a part of posts average depth of water in the river grows, and on others - cyclically changes with the general tendency to reduction. Aver age speed in them, accordingly, falls and grows. Stratification of interrela tions of a silt charge with other factors on years is observed. The reasons of reduction of a silt charge are: 1) agrarian and forest meliorative actions on a catchments of the river, hydraulic engineering construction; 2) grassy bed of the river; 3) change of a climate that promotes growth of temperature of a surface of soils and grassy bed of the river. In developed natural-climatic conditions expediently application on reservoirs of the antierosion organi zation of territory of the land tenure including agrarian- forests- meliorative actions that will allow to adjust outflow of a moisture from reservoirs to lower warming up of a surface of the soils, to provide against a high water protection and it will favorably be reflected in manufacture of agricultural production.</p>

Effect of Mutual Interference of Bridge Piers on Scouring in Meandering Channel
https://journals.bilpubgroup.com/index.php/hsme/article/view/4692
<p>Local scour is the reduction of original bed level around any hydraulic structure. Bridge failure due to scouring has made researchers study the cause of scouring and predict the scour depth and pattern around bridge piers and foundations. Several investigators have extensively studied local scour around isolated bridge pier, but modern designs of the bridges comprise of wide span and thus group of piers rather than a single pier. The flow and scour pattern around group of piers are different from the case of a single pier due to the interaction effect. The objective of present study is to investigate the effect of mutual interference of bridge piers on local scour experimentally around two piers in non-cohesive bed. Experiments were carried out on model bridge piers of circular cross section in a meandering channel. It was observed that when front and rear piers were placed at an angular displacement of θ = 40° and 80° respectively, maximum depth of scour is maximum. Here θ is the angle the line drawn at the inlet of bend to the line joining the centre of curvature and any point on the outer portion of the bend.</p>
