DAM. WATER. GROUND. PERFORMANCE.
Dams & Hydropower Monitoring Intelligence
RAUZ connects deformation, pore-pressure, seepage, survey, environmental and InSAR evidence to support engineer-reviewed dam and hydropower monitoring across operating assets, rehabilitation works and new projects.
Dams & Hydropower
Dam monitoring should explain performance, not just collect readings.
Dams and hydropower assets combine water load, ground and foundation behaviour, structural response, seepage, drainage, slopes, mechanical systems and long operating lives. RAUZ adds an independent monitoring-intelligence layer above existing instruments and field teams so that these evidence streams can be checked, compared and interpreted together.
It is the disciplined use of deformation, pore-pressure, seepage, water-level, survey, structural, environmental and operational evidence to understand whether a dam, reservoir, foundation, slope or water-conveyance asset is behaving as expected—and to identify what should be checked next when it is not.
Connect measurements to expected behaviour.
Reservoir level, uplift or pore pressure, seepage, displacement, temperature, joint movement, settlement and slope response become more useful when reviewed against loading, season, operations and design intent.
Monitor the mechanisms that matter.
FERC’s dam-safety framework links performance monitoring to potential failure modes so surveillance and instrumentation are focused on conditions that could affect safety.
Separate signal, uncertainty and action.
RAUZ structures the review so an owner or engineer can see what the evidence shows, what remains uncertain, whether independent datasets agree and which follow-up question deserves priority.
Above measurement. Before decision.
Dam Safety Questions
The useful starting point is a failure mechanism or performance question.
A monitoring programme becomes stronger when every instrument and inspection route can be linked to a question about dam, foundation, abutment, reservoir slope, spillway, powerhouse or water-conveyance behaviour.
Is seepage behaviour changing?
Review flow, reservoir level, drainage response and pore pressure to test whether the seepage pattern remains consistent with expected performance.
Are uplift or pore pressures responding as expected?
Pressure trends should be read together with reservoir level, drainage condition, foundation or embankment zones, seasonal variation and previous operating ranges.
Is movement stable, cyclic or progressive?
Compare crest, gallery, abutment, slope or structural movement by magnitude, direction, rate, temperature, reservoir cycle and independent survey evidence.
Is the foundation or abutment response changing?
Settlement, uplift, shear movement, drainage, piezometric behaviour and surface movement may need to be reviewed as one system rather than as separate charts.
Are water-conveyance assets performing normally?
FERC treats penstocks, power canals, flumes and tunnels as specific hydropower safety assets because failures can occur away from the main dam and may require rapid detection and response.
What changed during a flood, earthquake or unusual operation?
Event-based review should compare the before-and-after condition, instrument response, visual observations, water levels and any changes in operating or inspection status.
Monitoring principle: FERC’s Dam Safety Performance Monitoring Program explicitly connects instrumentation and surveillance with site-specific potential failure modes. That same logic is useful internationally even where a different regulatory framework applies.
Asset Map
A hydropower project is more than the dam body.
Monitoring scope can extend from the impoundment and foundation to spillways, abutments, galleries, slopes, tunnels, canals, penstocks, powerhouse structures and downstream interfaces. The project-specific scope depends on design, failure modes, operations and regulatory responsibilities.
Concrete or embankment structure
Displacement, settlement, joint or crack movement, pore pressure, uplift, internal temperature, seepage and drainage can contribute to performance assessment.
Foundation & abutments
Rock or soil foundation response, uplift, seepage paths, drainage, settlement, shear movement and abutment deformation can be central to dam safety questions.
Reservoir & adjacent slopes
Water level, rainfall, slope movement, groundwater, shoreline instability and wider-area ground motion may need to be reviewed together.
Spillways & outlets
Structural movement, gate or mechanical condition, discharge events, erosion-related observations and post-event inspections may form part of the wider evidence set.
Tunnels, canals & penstocks
Long water-conveyance systems can require distributed inspection and monitoring because a local failure may occur far from the dam or powerhouse.
Powerhouse & appurtenant structures
Settlement, vibration, structural movement, groundwater and interfaces with underground or surface works can be reviewed where they affect the monitoring objective.
Hydrometeorology & catchment conditions
Rainfall, snowmelt, inflow, reservoir level, downstream conditions and extreme hydrometeorological events may be material to performance interpretation.
Cascade & multi-dam systems
A common data model can help compare performance, anomalies and reporting across several assets while preserving asset-specific criteria.
South Caucasus & Georgia Context
Mountain hydropower needs the dam, catchment and surrounding ground to be read together.
RAUZ is based in Tbilisi, so Georgia is a natural first regional context for this industry page. The National Environmental Agency describes Georgia as having difficult terrain plus geological and climatic conditions associated with recurring landslides, mudflows, rockfalls, floods, avalanches and other natural hazards. Those conditions do not define any individual hydropower site, but they show why site-specific geology, hydrology, slope behaviour and climate records matter.
Do not assign a ground model from a country label.
Georgia’s National Environmental Agency maintains geological maps, hazard zoning, landslide and debris-flow monitoring, groundwater monitoring and engineering-geological assessments. A real dam review should use the official project investigation and site records.
Flood, snowmelt and rainfall context can matter.
Georgia’s official multi-hazard work includes floods, mudflows, avalanches, landslides, droughts, hail and strong winds across river basins. The relevant subset should be linked to the project catchment and operating question.
Remote sensing can extend the field of view.
The National Environmental Agency reported in 2026 that it is processing satellite imagery with InSAR to strengthen geological-hazard monitoring. For dams and reservoir slopes, InSAR can complement—not replace—ground instrumentation where technically suitable.
Enguri & Vardnili rehabilitation
The European Investment Bank describes rehabilitation of the Enguri and Vardnili hydropower cascade to restore generation capacity and safe operating conditions, including rehabilitation of the Vardnili I dam and spillways and provision of safety equipment.
European Investment Bank project page ↗Enguri HPP rehabilitation
Engurhesi’s official site documents continuing rehabilitation activities, including drainage-system works intended to improve safe operation and reduce filtration through the structure.
Engurhesi official update ↗Boundary condition: this page does not claim the geology, foundation condition, seepage mechanism, hazard level or monitoring requirement of Enguri, Vardnili or any other named project. Those conclusions require controlled project records and responsible project engineers.
Instrumentation Discussion
Choose instruments by the behaviour that must be detected.
The U.S. Bureau of Reclamation’s Instrumentation Group supports dam monitoring across water pressure, earth and total pressure, load, deformation, temperature and seepage, and links instrument type, number, location and reading frequency to the monitoring objective. The table below is an early-stage discussion framework—not a project specification.
| Performance question | Possible evidence | Typical asset area | Interpretation issue |
|---|---|---|---|
| How are pore pressure or uplift conditions changing? | Piezometers, observation wells, project-specific pressure measurements | Embankment, foundation, abutment, drainage zones | Sensor elevation, drainage condition, reservoir level, hydraulic connection, baseline and drift. |
| Is seepage quantity or character changing? | Weirs, flumes, seepage collection points, drainage flows, water-quality observations where specified | Gallery, toe drains, foundation drains, abutments | Reservoir loading, rainfall, blockage, maintenance and spatial consistency. |
| Is the dam or foundation deforming? | Survey monuments, total station, GNSS, pendulum/plumb systems, settlement devices, extensometers | Crest, galleries, abutments, foundation, powerhouse | Reference stability, reservoir cycle, temperature, long-term trend and differential movement. |
| Is lateral movement developing with depth? | Inclinometers or in-place deformation systems where suitable | Embankments, abutments, reservoir slopes, foundations | Stable reference zone, casing behaviour, depth correlation and baseline. |
| Are joints, cracks or interfaces changing? | Joint meters, crackmeters, displacement transducers, extensometers | Concrete blocks, galleries, structures, rock interfaces | Direction, temperature, mounting stability and relation to global deformation. |
| Is wider-area ground motion present? | InSAR-derived displacement, GNSS, survey and surface observations | Reservoir rim, abutments, slopes, access corridors | Line-of-sight geometry, coherence, reference frame, temporal sampling and ground verification. |
| How is the reservoir or catchment loading the system? | Reservoir level, rainfall, snowmelt/inflow where available, downstream levels and operating records | Reservoir, spillway, catchment, downstream channel | Time alignment, event duration, seasonal pattern and unusual loading. |
Selection rule: more instruments do not automatically make a safer monitoring programme. The system should be sufficient to test the relevant performance questions and failure modes, with credible baselines, justified redundancy, maintainability and a defined response route.
RAUZ Review Workflow
Move from instrument data to a performance argument that can be reviewed.
RAUZ can work with existing owner, consultant and instrumentation systems. The objective is to make the evidence trail clearer without making hardware replacement a condition of the engagement.
Identify the asset, monitoring objective, potential failure mode, operating condition and decision boundary.
Register instruments, locations, elevations, baselines, units, timestamps, calibration and maintenance records.
Screen gaps, jumps, flat-lines, resets, duplicates, range issues and reference changes.
Compare pressure, seepage, deformation, reservoir level, weather, survey, InSAR and operating events where relevant.
Assess whether behaviour is expected, unusual, progressive, spatially coherent or unresolved.
State supported findings, uncertainty, priority checks and the next inspection, verification or engineering question.
QA/QC first: USBR’s instrumentation service explicitly includes checking data validity, troubleshooting questionable data and reviewing performance anomalies before deeper dam-safety analysis.
Environmental & Climate Context
The dam and its environment are one interacting system.
Hydropower performance can be influenced by water level, rainfall, snowmelt, floods, temperature, slopes, groundwater and long-term climate conditions. These records should be used where they help test a defined physical mechanism or operating question.
Reservoir level, inflow & flood loading
FERC’s hydropower guidance treats flood evaluation, inflow design floods and dam performance monitoring as connected parts of safety evaluation.
Rainfall, snowmelt & seasonal change
Extreme precipitation or snowmelt can change reservoir loading, groundwater, slope conditions and access. The relevant meteorological record should be selected for the actual catchment.
Reservoir slopes & surrounding ground
Landslides, debris flow, rockfall, erosion or other ground hazards may affect reservoir margins, access, appurtenant works or downstream infrastructure.
Earthquake response
FERC maintains dedicated guidance on earthquake ground motions. Post-event review can compare instrumentation, inspection findings and changes from pre-event baselines.
Reservoir sediment & hydraulic condition
ICOLD maintains a dedicated technical committee on reservoir sedimentation. Where sediment affects intake, storage, hydraulic structures or inspections, it belongs in the operating context.
Environmental observations where required
Water quality, downstream conditions or other environmental parameters may be relevant to licence, impact-assessment or operating requirements and can be incorporated when defined.

Potential Collaboration Routes
RAUZ can sit above existing field delivery instead of competing with it.
A dam owner may already have an instrumentation contractor, survey team, designer, independent reviewer, SCADA system, IoT platform or InSAR provider. RAUZ can be used as a separate evidence-integration and interpretation layer where appointment and responsibility boundaries are clear.
Portfolio monitoring intelligence
Standardise QA/QC, exception review, trend commentary, traceability and recurring reporting across several dams without replacing asset-specific criteria.
Independent data review support
Prepare cross-instrument evidence, investigate anomalies and organise trend history so the appointed authority can focus on the safety conclusion and required action.
Monitoring & interpretation support
Support plan review, instrument rationale, baseline logic, diagnostics, reporting workflows and evidence preparation around defined questions.
Keep field delivery local.
Local specialists can continue installation, maintenance and readings while RAUZ provides remote QA/QC and engineering interpretation.
Add interpretation above acquisition.
A connectivity or dashboard provider can remain the acquisition layer while RAUZ handles diagnostic and engineering review tasks.
Connect satellite motion with field evidence.
RAUZ can compare spatial displacement patterns with survey, GNSS, reservoir, groundwater and local instrumentation where remote sensing is suitable.
Why RAUZ
A vendor-neutral intelligence layer for long-life water infrastructure.
RAUZ is the Environmental & Engineering Monitoring Intelligence Platform of Rauz Caucasus LLC in Tbilisi. For dams and hydropower, the value is not a proprietary instrument stack; it is the ability to work across existing evidence and make the reasoning easier to audit.

- Geotechnical, structural, survey, environmental and InSAR evidence can be reviewed together.
- Data QA/QC is separated from engineering interpretation.
- Failure modes can be linked to monitoring questions and evidence streams.
- Long-term trends can be compared with reservoir, climate and operating cycles.
- Independent review can be added without becoming the local installation contractor.
- AI-assisted screening can support—not replace—professional judgement.
- Automated reporting can reduce repetitive preparation while preserving traceability.
- Remote-first technical review can work with local dam, survey and instrumentation teams.
- Observation, interpretation, limitation and responsibility remain separated.
