Short summary

The potential flooding impacts from Imja glacial lake in Nepal were studied using a two-dimensional debris-flow model to evaluate the effectiveness of proposed measures to reduce possible flooding impacts to downstream communities by lowering the lake level. The results indicate that only a minor benefits is achieved with modest (~3m) lowering and lowering of 20m almost eliminates all flood impact at Dingboche.
