Tiivistelmä
The main goal of this study was to show the usefulness of the gabion retaining structure known as gabion mattress for the protection of a riverbank. Gabion mattress has been widely used in the protection of river banks from soil erosion and scour, and keep the slope stable to maintain channel stability and alignment.
This study aimed to highlight the different types of river bank protection methods, Gabion Mattress as one of them. An overview of some qualities of the gabion mattress was presented in this study, as well as several factors that need to be considered while designing and implementing gabion structures. In addition, this study described the construction and installing techniques of gabion mattress by using a hand-made weaving system.
For achieving the aim, the study was supported by the project work (case study) on the river ‘Kayar khola’ located in Chitwan, Nepal. From the field investigation, it was concluded that the protection work should be applied and different purposed activities were made. After the approval from DDC, the implementation of gabion mattresses along with launching aprons with different dimensions were carried out in the river bank. As a result, local people get benefits to upgrade their farming condition.
The thesis can be used as basic information about the protective measure for the bank of a river using gabion boxes or mattresses. Furthermore, the design presented can be used as a general guideline, but not as a strict code of practice.
