Water Level & Hydrology
Locate gauges, center the PTZ camera and recognize graduations and the waterline to record level changes. Surface velocity can be added where conditions permit.
INTEGRATED WATER MONITORING
One monitoring section
Water level, quality and site conditions
Integrate gauge recognition, spectral bloom detection, black-odorous water assessment and section monitoring on a shared timeline of spectral results, video events and hydrological changes.
01 / INTEGRATED SENSING
Hydrology × Spectroscopy × AI Vision
Blooms & Section Water Quality
Acquire water spectra and use models to assess chlorophyll-a, turbidity, suspended solids and bloom risk while tracking changes at the section.
Black-Odorous Water & Site Anomalies
Combine water-condition models with detection of unusual discharge, debris, oil and foam; use video and sampling for verification.
Bloom and black-odorous water detection provides assessment indicators to be reviewed with site conditions, spectral models, reference testing and manual checks.
02 / ONE SECTION, ONE TIMELINE
A Coordinated Monitoring Workflow
STEP 01
Water Level + Spectra + Video
Acquire corresponding spectra, images or sensor signals at the site and record acquisition conditions.
STEP 02
Time & Location Alignment
Align information by time, location and device identifier for cross-source comparison.
STEP 03
Alerts & Verification
Use trends and event rules to flag changes and link original data for review.
STEP 04
Follow-up Records & Retesting
Combine sampling, reference tests and repeat field measurements; record findings and follow-up actions.
Algal Bloom Monitoring
Fixed cameras and spectral equipment provide continuous observation, with drones or unmanned vessels extending coverage and supporting sampling of suspected bloom areas.
Black-Odorous Water Inspection
Combine water color, spectral models, unusual discharge and field records to identify trends and support outfall and pipe-network investigations.
Continuous Section Monitoring
Fixed stations or buoys sample periodically while water-level observations help explain relationships between spectral changes and hydrological conditions.
Alerts & Evidence Retention
Retain timestamps, water levels, model outputs, images, video clips and verification findings as traceable event records.
