An integral method for assessing the impact of dredging on the ecological state of river water resources

Abstract

The study is aimed at solving the urgent problem of the impact of dredging operations carried out in river channels on the hydroecological state of river sections as the most important water resource. Many different factors arising from man-made interventions radically change the hydrology and hydroecology of rift areas. Taking into account all kinds of changes during the design phase leads to both the creation of sustainable tracks and the minimum impact on the environment. The aim of the study is to develop an integral quantitative method for assessing dredging and channeling works on the hydroecological state of river sections. The proposed method is based on the formalization of influencing factors and an algorithm for their quantitative assessment. It has a number of properties that distinguish it from the calculations previously used for hydroecological assessment, describing the interaction of the channel, flow and technogenic systems, in particular, the ability to obtain integral quantitative data. The classification of factors is proposed: by the degree of the direction of impact, the size of the area of influence, by the time duration. The possibility of using this method to create artificial neural networks for the design of dredging is shown. The possibility of functioning of an artificial neural network of the perceptron type, consisting of several layers of neurons, has been demonstrated.
