Watershed Assessment of River Stability and Sediment Supply (WARSSS) 2nd Edition

684 pages, 380+ Figures, Worksheets, Flowcharts, & Tables

Second Edition includes updated illustrations, worksheets that correspond to the River Stability Field Guide, and an expanded monitoring chapter


  • Implements a three-phase assessment to quickly identify processes and land uses responsible for erosion, channel instability, and disproportionate sediment supply
  • Provides a cumulative watershed impact analysis to prioritize mitigation
  • Developed in partnership with the USEPA for national application for impaired rivers available at
  • Includes a case study of the Wolf Creek Watershed
  • Includes CD-ROMs of all worksheets and a 45-day free trial of RIVERMorph
  • Presents validation and monitoring methods to improve prediction models and to better understand river processes and response
  • Assesses reach condition for river restoration planning and design purposes

Techniques and Procedures Include:

  • Channel Stability Rating Procedure
  • BANCS Model to predict total annual streambank erosion
  • Road Impact Index to predict delivered annual source sediment
  • FLOWSED model to predict total annual sediment yield
  • POWERSED model to predict sediment transport capacity
  • Sediment competence procedure
  • Overall sediment supply ratings related to specific sources, processes, and locations



Stream restoration software with virtually every design function you need built into a single program.

RIVERMorph significantly reduces the time required to assess, analyze, and design streams by putting the tools you need right at your fingertips.

RIVERMorph includes the procedures developed and taught by Dave Rosgen and Wildland Hydrology.

Tools are provided for stream classification, survey data plotting, discharge gage analyses, hydraulic evaluation, Pfankuch channel stability analysis, streambank erosion prediction, regional curves, competence evaluation, river stability assessment, and the FLOWSED/POWERSED models to assess sediment transport capacity.
