Calculation of its dynamically stable cross-section in the steady motion of the channel flow

The paper presents the results of the field and numerical studies of the bank destruction in the middle section of the Amudarya River. The article presents the main factors of destruction of the banks during floods and low water flow. In addition, recommendations for protecting the coast from erosion are also developed. As a result of research into the process of intensive local reshaping of an easily eroded channel, hydraulic schemes have been developed for the occurrence of local bank erosion both in steady and unsteady motion in an open stream. The recommendations are based on some patterns of interaction between the river channel and the flow during the period of low water and high-water flow. The external manifestation of this interaction is the coastal deformations, leading to the planned displacement of the channel.

“…This phenomenon was called deigish, which in translation into English means "bad water". Later, this term was extended to all cases of coastal erosion [4][5][6][7].…”

Technology for the production of disubstituted pyrroles

2023

In this work, we studied the catalytic synthesis of pyrrole and their derivatives from ketoximes and acetylene in the liquid phase under normal conditions in the presence of homogeneous catalysts. Mathematical modeling of the experiment was carried out using the Box-Wilson method and the optimal conditions for the synthesis of a number of pyrroles were found. The catalytic synthesis of pyrrole under vapor phase conditions in the presence of heterogeneous catalysts has been studied. Low-temperature polyfunctional catalysts have been developed that provide the highest yield of pyrroles.
