DESIGN AND CONSTRUCTION OF CAUSEWAYS AND LOW LEVEL SUBMERSIBLE BRIDGES ON RURAL ROADS AND ORDINARY DISTRICT ROADS

This paper discusses various aspects of the design and construction of causeways and low level submersible bridges on Indian rural roads. These causeways are often used to provide river crossings to link villages with neighbouring towns, but are often easily damaged because inadequate resources have been allocated to their construction. The main types of causeway are: (1) non-vented causeways; (2) vented causeways; (3) high level causeways and low level submersible bridges. The topics considered are: (1) common modes of failure of causeways, especially in very wet weather; (2) previous guidelines for causeway design; (3) terminology used in the paper; (4) types of causeway; (5) characteristics of causeways constructed in the past; (6) discharge calculations; (7) protection works; (8) scour depth calculations; (9) relative merits of high level causeways and low level submersible bridges; (10) ideal sites for causeway construction; (11) general features of well-designed causeways; (12) special features of well-designed causeways. An appendix presents a nomographic procedure for approximate calculation of the length of flanks to be protected when the vents of a causeway are obstructed.
