Guidelines for Design and Construction of River Training and Control Works for Road Bridges (Second Revision) 2019 الطبعة
IRC 89:2019 delivers detailed recommendations for designing and constructing river training and control structures aimed at safeguarding road bridges. It focuses on hydraulic and structural factors to maintain the stability and protection of bridge approaches against river currents, erosion, and scour. This code is vital for engineers involved in creating river training features like guide bunds, spurs, and aprons to counteract hydraulic impacts on bridges.
