5.It often becomes necessary to relocate portions lf natural water courses to make way for a roadway or an airport.Often drainage structures,both large and small,can beeliminated by relocating reaches of existing streams to keep them on one side of the roadway rather than crossing back and forth.At many structure sites the field investigations indicate that channel relocations an improvements above andbelow the structuer may provide a better situation from the hydraulec standoint.A decrease in initial cost of the structure installation is possible;however,maintenance and possibe future cost should not be overlooked in considering the feasibility lf this choice.Also,considerable caution should be taken in dealing with the changing of natural water courses.Such an undertaking repuires thorough engineering analysis.
