Bihar floods despite rainfall deficit. Erratic weather, upstream flows, Ganga backwater cause it. Embankments fail, worsening issues by confining rivers and causing siltation. Comprehensive strategy needed, including revising embankments, restoring drainage/floodplains, better land-use, early warnings. Enhanced inter-state/international water management coordination needed. Renegotiating Ganga Treaty, addressing Bihar’s silt concerns with updated data/climate projections, needed for effective mitigation.
