One of the main problems in operation hydrosystems for various purposes is silting up reservoir. Silting a reservoir leads to decrease useful capacity. And, course, hydrosystem's facility will not be able fully perform its functions. This issue particularly relevant territories located arid zone with transboundary rivers, whose water resources are used industries different types consumption (fi...

Silting in river is a dynamic process, so it needs to regular desilting. At present, underwater siltation monitoring still its early days and based on experience. This paper puts forward the criterion of discrimination, which flood discharge section decreased by 20%. It used method steady uniform flow open rectangular trapezoidal channel for calculation. The results show that reference values d...

A gentle algebra gives rise to a dissection of an oriented marked surface with boundary into polygons and the bounded derived category has geometric interpretation in terms this surface. In paper we study silting theory its underlying particular, show how mutation corresponds changing graded arcs that some cases results octahedral axioms flipping diagonals quadrilateral as work Dyckerhoff Kapra...

The silting process of urban reservoirs has been occurring in many regions across the world. However, identifying main sources sediment and controlling are still unsolved problems regions, mainly developing countries such as Brazil. In this study, we identify which land use most influences siltation reservoirs, how different tributary streams contribute to two located Campo Grande, Midwestern T...

Silting and Calabi–Yau reductions are important processes in representation theory to construct new triangulated categories from given ones, which similar Verdier quotient. In this paper, first we introduce a reduction process of category, is analogous the silting (Calabi–Yau) reduction. For category T $\mathcal {T}$ with pre-simple-minded collection (pre-SMC) R {R}$ , U {U}$ such that SMCs bij...
