The proposed research will test the following hypotheses and conclusions from previous work: (1) the wetted perimeter of the Bighorn River continues to remain relatively stable since dam emplacement, as found in a previous study; (2) geomorphic diversity within the channel is likely stable since the previous study and any recent erosion within the channel does not fall outside of historic fluctuations (3) physical excavation is required to reconnect many endangered and disconnected side channels along the Bighorn River, as model predictions indicate that the side channels will not be reconnected with high flows alone; (4) once restored, high flow releases can help prevent aggradation at side channel entrances.
