Introduction to Low-Tech PBR of Riverscapes

Introduction

We first introduced low-tech process-based restoration (PBR) by defining it and talking about:

  • the primary impairment it addresses: structurally-starved riverscapes
  • the primary processes promoted with low-tech PBR: wood accumulation and beaver dam activity
  • the typical structures used to reverse structural starvation

For the workshops and WATS 5620 class, we have participants do two exercises:

Past Years' Resources

2020 Content

In Fall 2019 WATS 5340, we introduced the topic of low-tech PBR in the Principles topics. As such, we didn't cover it again in the Spring (WATS 5350), but we draw your attention to it here. We did not give an introduction to the different types of low-tech treatments, and we provide that lecture here:

Low-Tech Structures

2020 WATS5340 Week 7

Having previously covered principles, we work through the diversity of low-tech approaches and structure types in this lecture so you have a handle on what you're going to be using in your designs.

This talk is elaborated in Chapter 1 & Chapter 4 of the design manual.

Recorded Lecture

2019 Content

This introduction corresponds to the first two chapters from the Low-Tech PBR Design Manual.

Principles

We then transitioned into the bigger background problem and scope, and the core principles of low-tech PBR:
