TLDR
In this paper, the use of numerical methods for the design and analysis of hydraulic engineering structures requires an accurate determination of the model of subsoil structure and the phenomena occurring within it.Abstract:
The use of numerical methods for the design and analysis of hydraulic engineering structures requires an accurate determination of the model of subsoil structure. The article presents one of the geophysical methods – electrical resistivity tomography (ERT), which allows for precise, spatially instant recognition of the substrate and the phenomena occurring within it. The methodology, the applied algorithm for numerical calculation, and data processing procedure are discussed. This article also introduces a method of inversion which relies on finding the actual model and presents examples of its application.read more
