Saint Petersburg Flood Protection Dam as Tool to Solve the Environmental Tasks

Abstract

The paper grounds the necessity to conduct the large-scale field experiment on manoeuvring with the floodgates of Saint Petersburg Flood Protection Complex (FPC). The paper presents the results of I-stage experiment and the program of II-stage experiment. The aim of the experiment is the verification of the possibility to manage the hydrological, sanitary and ecological state of the Neva Bay and the eastern part of the Gulf of Finland of the Baltic sea by means of manoeuvring with Flood Protection Complex floodgates. In order to develop the program of field experiment implementation it was necessary to assess the sanitary and ecological state of water ecosystem under present conditions. The assessment was based on monitoring data concerning the certain priority parameters obtained from the selected representative measuring points. On the basis of the analysis of water quality and the state of the Neva Bay and the eastern part of the Gulf of Finland the scheme for manoeuvring with floodgates of the FPC together with the sequence of order of their opening and closing was developed. Recommendations regarding the conditions and terms of conducting the experiment were developed.

Mathematical Modeling of the Test Process of Construction Materials

“…Mathematical-statistical processing of test results in applied and technical sciences and researches is an objective reality in modern research activities and aims to more accurately identify the patterns of the studied processes, phenomena and objects and on this basis to develop mathematical models in the form of regression links [4,5]. The most common is the least squares method (LSM), which allows to get ) ,..., , ; (…”
