(v) Stabilisation of River Channel Weak river banks, which are likely to cave in or get eroded, need to be protected by training methods, such as stone pitching, lining, and so on. In some cases, the stability of the bed may also be endangered in some reaches due to increase in the bed shear on account of local flow conditions.
12.5. RIVER TRAINING METHODS The planning and design of river training structures is accomplished by using empirical methods and reliance has to be placed on the intuition and judgement of experienced engineers. Model investigations are also resorted to for finalising the plans and design of river training structures. Commonly used methods of river training have been briefly described in the following sections.
