LTPBR V2 Design Protocol

Overview

The LTPBR V2 Design Protocol is used to develop conceptual restoration plans. It helps users visualize:

  • Proposed restoration structures and their spatial & temporal distribution.
  • Anticipated gemorphic & hydraulic changes to the riverscape.
  • Complex objectives for multiple structures.

Essentially, the protocol allows restoration designs to convey the location, orientation, type, and expected hydrogeomorphic response of proposed structures. Users can create multiple designs to represent different phases of a project or to show various potential outcomes. Finally, the protocol allows users to digitize important riverscape features that might affect project logistics or influence the design itself.

Layers & Metrics

The protocol uses seven layers to organize different aspects of a restoration design planning. These layers represent riverscape observations, structure locations, complex extents, and Zones of Influence (ZOI).

  • Structure locations can be digitized as either points or lines, depending on user preference or knowing specific details like exact geometry or structure length.
  • Observations are digitized as points, lines, or polygons to highlight different feature’s location, orientation, spatial distribution, or key attributes.
  • Complex extents and ZOIs are digitized as polygons to illustrate the area influenced by a single structure or group of structures.

Design-Example Example of LTPBR V2 Design protocol in practice at Bailey Flat. Digitized layer extents and symbology are stored in the QRiS geopackage and can be displayed in any QGIS (.qgz) project.

Layer Attributes

Description: highlight key valley bottom features and other important critical considerations that influence the restoration design

AttributeDescription
Building MaterialsIdeal areas for harvesting materials to be used in structure construction.
CautionAny feature that deserves caution, especially for the safety of construction or monitoring crews.
Design ConsiderationsA feature or observation that should be considered in an LTPBR design, best clarified by including notes about how the featured might be incorporated into an LTPBR design.
LogisticsUsed to provide project annotations such as material staging locations, parking areas, camping, etc….
Photo ObservationPhoto observations made in the field.
OtherOther features that may be relevant to LTPBR planning, design, or implementation.
Riverscape FeatureAny riverscape feature that might be important to make note of in a design that might provide opportunities or risks. It is especially important to mark those that were observed in the field but hard to detect using aerial imagery.
