Probabilistic Dam Erosion Risk Evaluation

TRRP Training: 2022 Program

presented by: GSI Environmetal Inc.

Texas Risk Reduction Program regulations (TRRP; 30 TAC 350) establish consistent risk-based protocols for assessment and response to soil, groundwater, or surface water impacts associated with environmental releases of regulated wastes or substances.

Presented by GSI Environmental Inc., this popular and informative training series is a must for professionals who need a working understanding of TRRP and those needing to stay up-to-date with the latest TCEQ TRRP guidance and policies.

TRRP Training Course (2 Days): Provides an overview of the TRRP framework and step-by-step training on property assessment and response action procedures established under the TRRP rule

Attendees will become acquainted with rules, key guidance and policies covering affected property assessments, protective concentration levels, and response actions. The course material presents strategies for efficient project management in compliance with TRRP and explains the various report forms adopted by TCEQ.

Abstract

Download Paper

Several existing dams worldwide have experienced rock foundation and downstream scouring/erosion caused by the large hydraulic power of impinging water jet resulting from overtopping during extreme floods. Hydrologic and geologic systems are dynamic and heterogeneous, but our knowledge of the parameters of these systems is often limited. This paper discusses the various uncertainties associated with dam erodibility analysis and utilizes a probabilistic approach to address the uncertainty issues. It particularly focuses on high concrete dams with unrecognized adverse rock conditions. Terrestial LiDAR and three-dimensional photogrammetry can be used to obtain high-resolution data for developing statistical rock joint parameters needed in analysis. The stability/erodibility of the rock foundation was evaluated based on Annandale’s Erodibility Index method and Bolleart’s Comprehensive Scour Model. Uncertainty of the Annandale’s erosion criteria is addressed in the analysis. Dam erosion hazard curves can be developed considering the recurrence characteristics of extreme hydrologic events.
