Thirty Years of Terrain Evaluation for Route Corridor Engineering

This chapter on terrain evaluation for route corridor engineering is from the proceedings of an international conference on the terrain and geohazard challenges facing onshore oil and gas pipelines (June 2004, London, United Kingdom). The author stresses that the process of locating and designing linear engineering structures, such as pipelines and roads, through unstable mountain terrain requires great attention to the details of physiography, ground conditions, and geohazards. The author describes the 30 years of using geomorphological mapping in some of the most unstable terrain of the Himalayas for the purpose of route location and design for a mountain road, the Dharan-Dhankuta Road in east Nepal. The author concludes that an assessment of the road, thirty years after its construction, supports the success of both the design and the geomorphological surveys that contributed to it. Of course, there have been some unpredicted changes over those three decades, including significant changes in the geomorphology of the area due to rainstorms, floods, and an earthquake. The author concludes that the geomorphological mapping surveys reviewed in this chapter remain a model for route corridor selection and design, when combined with modern structural geological and engineering geological assessments.
