Hydropower: The Importance of Engineering Geological Investigation

Engineering geological investigations play a vital role in the planning and design of hydroelectric projects, as they provide crucial information about the geological structure and properties of the terrain that the project will be built on. This information is essential for determining the techno-economic feasibility of a proposed project and ensuring that it meets current safety standards.

The mainstay of geological investigations for hydroelectric projects is subsurface exploration, which includes geophysical investigation, diamond core drilling, and exploratory drifts. These methods allow engineers to gather information about the lithology, stratigraphy, and geological structure of the area, as well as the geomechanical properties of the ground and the presence of any extraordinary phenomena that may affect the stability and safety of the proposed structure.The scope of the geological investigation is determined by the stage of the project, with preliminary and reconnaissance investigations conducted in the first phase and subsequent phases focusing on increasing the detailing and accuracy of the information gathered. Site-specific geological mapping is also carried out through extensive surface traverses of the project area and the use of aerial photographs and satellite imagery to cover inaccessible areas. The information gathered from engineering geological investigations is used to design and construct hydroelectric projects in a safe and cost-effective manner. It allows engineers to identify potential hazards and design mitigation measures to ensure the stability and safety of the structure. It also helps in identifying the most suitable location for the project and in the design of the dam and powerhouse, as well as the alignment of tunnels and bridges.

In conclusion, engineering geological investigations are an essential part of the planning and design of hydroelectric projects. They provide crucial information about the geological properties of the terrain and help to ensure the safety and cost-effectiveness of the proposed structure. Without proper geological investigations, hydroelectric projects may be built on unstable terrain, putting the structure and the surrounding communities at risk.

Chungthang Hydro-Dam Breach: Lessons for Nepal's Big Hydropower Ambitions

Chungthang Hydro-Dam Breach: Lessons for Nepal's Big Hydropower Ambitions Introduction: A catastrophic glacial lake outburst triggered flash floods in North Sikkim's Mangan district on October 4, 2023, leading to the breach of Sikkim's Chungthang dam, the largest hydropower project in the state. This incident has sent shockwaves through the region, emphasizing the need for Nepal to carefully assess the risks associated with large hydropower dam projects. To make informed decisions, Nepal must draw lessons from past dam failures and natural disasters, understanding the implications of such events on a national scale. The Chungthang Hydro-Dam Disaster: The Chungthang dam, a vital component of the 1200 MW Teesta Stage III Hydro Electric Project, is a symbol of power generation in the region. However, the recent breach underscores the potential consequences of dam failures. As flash floods wreaked havoc in Chungthang and Mangan districts, damaging infrastructure and lea
