Stabilization of ravines: Case study of Sabarmati river, Gujarat State, India

The ravines along the bank of Sabarmati river have been undergoing gradual erosion thus posing threat to the adjacent structures. The primary aim of this paper is to present a suitable cost-effective solution for stabilization of these ravines. Gabion gravity walls being flexible in nature have been provided at certain locations which required immediate attention. The construction of these walls has been monitored and it is explained here in detail. It was realized that gabion gravity walls are flexible and eco-friendly solution, however they workout to be still uneconomical. Reinforced soil walls with gabions as facia and gabion mesh as reinforcement have been studied to be flexible, eco-friendly and cost-effective solution. A comparative study of the cost of both types of structures has been performed and reinforced soil walls with gabions as facia and gabion mesh as reinforcement has been suggested to be provided along the remaining stretch of ravines.
