Flooding accounts for the most costly and frequent natural disaster in North America. In the last decade, flood risks have increased with climate change, threatening the safety and property of citizens across the country. NSD assists public agencies with protecting their communities from emergency flood events through restorative flood protection design and analysis. We begin with assessment of root causes, and progress through geomorphic assessment, hydraulic/hydrologic and sediment transport analysis. We then document the problem to inform the public and develop design methods that protect human infrastructure and restore the river ecosystem. The results are self-sustaining with long-term benefits of lower costs and streamlined regulatory approvals.
