The purpose of this study was an assessment of the impact of topography and its parameters on the accident rate of pipelines. Existing topography creates a spatial matrix for natural processes, which finds reflection in the
system-morphological approach by A. N. Lastochkin. We took advantage of the statistics of the US National Pipeline Mapping System (NPMS) and carried out the geomorphological analysis of various accident sites. We also used for this cartographic and morphometric methods of research. With the help of statistical analysis, we revealed the relationships between the values of the main geomorphological parameters and the accident rate of pipelines.
