In the Drylands of Northern China, such as the Loess Plateau region, a buffer zone of planted forests—a “Green Great Wall”—has been created in the last five decades. These government programs have often generated unintended environmental consequences, and have failed to achieve the desired benefits. Planted forests withhold erosion, dust storms and silting of streams but may reduce stream flow ...

In the current study, the applicability of the Annandale method was verified based on the results of silting and sediment distribution measurements carried out in eight small reservoirs, with a capacity that does not exceed 5 million m3. It was found that the application of this method is possible only in the case of small reservoirs, in which the sediment load is deposited in the near-dam zone...

We study higher cluster tilting objects in generalized higher cluster categories arising from dg algebras of higher Calabi-Yau dimension. Taking advantage of silting mutations of Aihara-Iyama, we obtain a class of m-cluster tilting objects in generalized m-cluster categories. For generalized m-cluster categories arising from strongly (m + 2)-Calabi-Yau dg algebras, by using truncations of minim...

River basins are key components of water supply grids. River basin operators must handle a complex set of objectives including runoff storage, flood control, supply for consumptive use, hydroelectric power generation, silting management, and maintenance of river basin ecology. At present, operators rely on a combination of simulation and optimization tools to help them make operational decision...

In this paper, we study two-term tilting complexes for preprojective algebras of non-Dynkin type. We show that there exist two families complexes, which are respectively parameterized by the elements corresponding Coxeter group. Moreover, provide complete classification in case affine type showing any silting complex belongs one them. For purpose, also discuss Krull–Schmidt property homotopy ca...

Forecasting and preventing silting of hydraulic structures, irrigation canals, reservoirs, as well improving methods for maintaining their throughput, is particularly important. In this regard, special attention paid to research work aimed at calculation methods, taking into account the variability channel factors in design construction structures planned construction. This article analyzes inf...
