Literature on Low Water Stream Crossings (LWSC) is reviewed and analyzed to develop a set of design criteria for such structures. Case histories of existing structures are documented and an approach to decision criteria and economic analysis on which decisions can be made are included. Hydraulics of LWSC and the means of erosion protection are also
...
Commonly used Low Water Stream Crossings (LWSC) of different types are described and the characteristics of their efficient design are discussed. Selection factors for LWSCs are listed, along with a set of general and specific design considerations. A method, based on economic risk analysis, is recommended for the final selection and design of ford
