Working at the interface between soil and water, we are frequently involved with the development of bioengineering solutions and bank stabilization design. Our geomorphologists and engineers were primary authors of the U.S. Bureau of Reclamation’s National Manual, “Large Wood Design Guidelines.” We are known for setting industry standards for design of engineered logjams that support road embankments in dynamic river systems and are currently serving the Federal Highways Administration, WSDOT and other public agencies in this capacity. NSD’s solutions to bank instabilities combine analysis of natural stream processes, with the application of state of the art materials and tried and true civil engineering techniques.
