  • Spillways can divert sand from river to rebuild wetlands

    Sand deposits were worked into trains of dunes when flood water flowed into the Bonnet Carr Spillway in Lousiana. Once the flood subsided and the spillway was closed, the water drained and dried from the spillway, thereby exposing the dunes. Trees and shrubs near the top of the oblique aerial photograph provide scale.
