Stream Investigation & Design Workshop

Concepts and techniques for stabilizing streams that help you meet your project goals. Hosted by North Jersey Resource Conservation & Development.

Streams all around the state are in need of attention – threatening infrastructure and valuable property.  Action needs to be taken, and your team needs to come up with a plan.  Let Dave Derrick show you his techniques for reading a stream, analyzing the forces at work, and developing stream stabilization and restoration designs that stand the test of time!  Innovative, environmentally sensitive, and cost-effective approaches to restoration will be explained in detail. Comprehensive case studies will be presented.  Field trips will give participants the opportunity to observe how practices perform and to develop conceptual designs for future projects.  Workshop goals are to:

  • Develop a philosophy of bank & bed stabilization design by seeing the stream as a complex system that responds to both local and system-wide processes
  • Develop project goals & objectives to address everyone on your team
  • See innovative bank protection methods and learn how to apply these techniques to potential project sites
  • Learn how to analyze bed and bank erosion from an experienced practitioner and practice how to read a stream
  • Site visits on Day #2 and Day #3: Walnut Brook, Flemington (Hunterdon County); Lopatcong Creek, Phillipsburg (Warren County)
  • Apply concepts of the Channel Evolution Model (CEM) and Regime Theory to know when you need grade control
  • Understand the importance of project constructability, monitoring and maintenance
  • Apply concepts in the field incorporating project goals, analyzing flow regimes and erosional process; developing stabilization plans that will perform!
