I recently came upon this short video animation about river management at the catchment scale. It is preferable that our water resource engineers attempt to mimic natural processes when attempting to manage the flow of water, but not only in times of excess, but also in times of drought. This video emphasizes flood mitigation, but the same strategies help during times of low flow. Increased groundwater, floodplain, and wetland connectivity provides a slow release of groundwater to streams and maintains stream flows throughout drought periods. Rivers need water, fish need water, people need water. Check out the video and let me know what you think.
