Owners of dams, spillways, and other appurtenant structures face multiple challenges in developing, implementing, and funding dam safety programs. Exacerbating these challenges is the evolving nature of risks and regulations and the need to incorporate specialized analysis methods and lessons learned from past events.

A robust, modern, risk-informed dam safety program is not merely maintenance-oriented and reactive but also predictive and proactive, requiring proper gathering and assessment of data. These data will be used in engineering assessments, which may indicate the need for operational or physical modifications to address dam safety concerns.

Geosyntec is highly experienced in the use of both standards-based deterministic evaluations and risk-based probabilistic evaluations of earthen dams, concrete dams, spillways, outlet works, and other ancillary structures using state-of-the-practice modeling and analytical methods. Geosyntec provides engineering design and design review of new structures and rehabilitation and enhancement of existing facilities. Geosyntec applies risk-informed approaches to estimate likelihood of failure and consequences in terms of life safety and economic losses.

Pioneers in using risk-informed decision making (RIDM), we help our clients through the process of evaluating the results of risk analyses and developing program-level or executive-level decisions based on those results. We help clients leverage RIDM to: assess the adequacy of in-place control measures; refine existing plans to avoid significant new investments; develop reasonable risk-reduction investments where needed; and prioritize action plans to achieve risk management and asset management objectives.
