This is illustrated by the case study of “Sharda River”. This transitional behavior of river Sharda (i.e. braided cum meandering) invites many bridges along with the major bridge. The iterative variability in flow patterns over decades invites relocation of same bridge or extraordinary lengthening of required bridge span. A proposal of guide bund in this case, has helped to avoid discrepancy in fixing span, flooding of other side of the bank and providing unaffected flow to avoid flooding at downstream of the river.
