Abstract
The research area is located in north-western Poland. It is the city of Szczecin with a particular emphasis on the Międzyodrze islands. The area of the EcoGenerator Waste Disposal Plant is part of the research area. The analysis of the geological structure of the subsurface layer of Earth’s crust within Szczecin, was carried out with particular emphasis on the EcoGenerator Waste Disposal Plant. The analysis of height changes of the benchmarks, was based on archival materials measured in two campaigns. A detailed recognition of the geological structure in connection with the analysis of changes in the height of the benchmarks was important. This enabled stable benchmarks to be located in several areas of Szczecin. They formed the basis for reliable monitoring of surface deformations of organic and existing sediments within the EkoGenerator Plant. The application of an appropriate three segment control and measurement system. In the area around the EcoGenerator Plant, vertical movements of the area were observed using the InSAR Small Baseline Subset Method. An InSAR analysis is only used here for very broad identification of the moving area. The radar data came from Sentinel 1 A and 1 B satellites. A total of 129 images from 15.11.2014 to 28.07.2019 were used.The results of the analyses conducted, form the basis for discussion and act as a summary of the considerations in this paper.
Highlights
As a port city, Szczecin is an important communication centre
The analysis of the first and second class levelling lines enabled the selection of one more reference points for the first segment of the control and measurement system
This third geologically stable point in the area of Szczecin will form the basis for the studies of organic deposits surface deformation and engineering structures in 3D space using GNSS [4]
Summary
The economic structure of the city is diverse by port development. It has been shaped and is progressing towards maritime economy development. The main industries are shipyards, steelworks, paper mills, as well as seaports. Most of these are located in the vicinity of the Miedzyodrze islands. The influence of the industrial infrastructure has become apparent within the Odra islands [1]. Deformation measurements of many engineering facilities were not carried out. Reliable monitoring of the deformations of existing and planned engineering structures on the Oder islands in Szczecin justified the planned and implementation of an appropriate control
