  • Patent number: 4288175
    Abstract: The downstream side of earthen dams is provided with relatively non-erodable reticulate reinforcement so that whenever the upstream water level has exceeded dam overtopping level, the reticulately reinforced dam will resist the forces of overtopping water flow and reduce the likelihood of dam breaching and consequent valley floods. Methods of internally reticulately reinforcing existant earthen dams with a plurality of transversely extending concrete check-walls and longitudinally extending embedded concrete spacer-walls are also disclosed.
