The Critical Role of Aging Dam Infrastructure: Risks, Challenges, and Modern Monitoring Solutions Dams are pivotal in irrigation, flood control, hydroelectric power, and urban water supply. However, many dams across the globe are aging, leading to heightened risks of structural failure. With over 10,000 large dams estimated to be over 50 years old, the aging infrastructure presents serious safety concerns for humans and ecosystems. Climate change, poor maintenance, and inadequate monitoring further exacerbate these risks. Structural Integrity Issues in Aging Dams Aging dams face various structural issues due to material degradation over time. Key challenges include: 1. Concrete Fatigue and Deterioration: Over time, concrete used in dams suffers from cracking, spalling, and expansive cracking due to chemical reactions like alkali-silica reaction (ASR). Stress from decades of water pressure, thermal expansion, and contraction worsens this degradation. 2. Steel Corrosion: Concrete reinforcement steel corrodes when exposed to moisture and chemicals, leading to cracking, loss of structural integrity, and potential failures. 3. Seepage and Internal Erosion: Uncontrolled seepage through dams can lead to internal erosion or "piping," destabilizing the dam structure. Case Study: Oroville Dam Crisis (2017) The Oroville Dam incident highlighted the risks associated with aging dam infrastructure. Poor maintenance led to severe erosion in the emergency spillway, prompting the evacuation of over 180,000 people downstream. This event underscored the need for regular monitoring and maintenance of dam systems.

In extreme cases, sediment buildup can block spillways, increasing flood risks.
● Water Quality and Ecosystem Impact: Sediment-rich water affects downstream water quality, disrupting aquatic habitats and leading to fish deaths. Poorly maintained dams can alter river flows, negatively impacting ecosystems reliant on seasonal flooding. Safety Risks: Flooding and Catastrophic Failures Aging dams are vulnerable to catastrophic failures, particularly during extreme weather events exacerbated by climate change. Increased rainfall and flooding place stress on spillways and can lead to overtopping and dam failure. Additionally, internal erosion caused by seepage (piping) is a significant failure risk in older structures. Case Study: Edenville and Sanford Dam Failures (2020) The failures of the Edenville and Sanford dams in Michigan, caused by heavy rainfall and poor maintenance, resulted in widespread flooding and property destruction. This case highlights the urgent need for enhanced monitoring of aging dams. Modern Technologies for Monitoring and Rehabilitating Aging Dams To mitigate these risks, modern monitoring solutions are being implemented: 1. Geotechnical Monitoring Instruments: Piezometers and inclinometers monitor dam stability by tracking pore water pressure and structural deformation. 2. Remote Sensing Technologies: InSAR and LiDAR technologies enable engineers to detect subtle shifts in dam structures, providing early warnings of potential failures. Case Study: InSAR Monitoring in Italy InSAR technology has been successfully used to monitor dam deformation in Italy's seismic regions. It provides millimeter-scale movement detection, offering early signs of instability. 3. Automated Data Loggers and Early Warning Systems: Continuous data collection from automated loggers triggers early warnings when critical thresholds are reached, alerting dam operators to potential risks. Encardio Rite’s Role in Dam Safety Encardio Rite’s Infinitus system integrates various monitoring technologies, offering real-time data on dam performance. Through Proqio, a unified platform for data acquisition and risk assessment, dam operators can continuously monitor parameters like seepage, pressure, and deformation. The platform uses advanced predictive algorithms to detect anomalies and trigger automated early warnings, ensuring timely interventions.
