Dams
Monitor dam deformation, settlement, and structural behavior with Osprey instrumentation to verify design assumptions and support safe operation.
Overview
Dam monitoring tracks deformation, settlement, and structural behavior of dam embankments, concrete sections, spillways, and appurtenant structures during construction, first filling, and long-term operation so you can verify design assumptions, detect developing issues early, and support safe operation.
Common monitoring goals
Dam projects typically focus on a small set of critical behaviors:
- Settlement and consolidation of embankment dams across the crest and downstream shoulder where staged construction and reservoir loading drive vertical movement.
- Deformation and rotation of concrete dam sections including monolith tilt, joint movement, and structural response to hydrostatic loading.
- Internal deformation and shear within embankments to identify developing slip surfaces or zones of distress.
- Spillway and appurtenant structure movement including settlement, tilt, and differential displacement relative to the main dam body.
- Correlation with reservoir level, seepage, rainfall, and temperature to understand how environmental and operational conditions influence dam behavior.
- Continuous data for alarm thresholds and compliance where regulatory requirements, trigger levels, or risk controls apply.
- Back-analysis and design refinement using measured performance to improve interpretation and future dam design decisions.
Relevant Osprey products
Use these Osprey systems to measure the most common dam behaviors.
OTS
OTS measures orientation and rotation along a line or curve to profile deformation and tilt of dam walls, concrete sections, and embankment slopes.
ASP
ASP measures distributed settlement along a nominally horizontal profile using the hydrostatic principle, useful for tracking settlement across dam crests and broad embankment surfaces.
IPX
IPX is a magnetic-field sensitive probe for automated monitoring of standard magnetic extensometer installations to measure vertical displacement at depth within embankment dams and foundation ground.
