What we do

Services built around modelling, monitoring and risk action.

From basin-wide IoT networks to building-level damage prediction, we turn live environmental data into decisions that protect people, infrastructure and capital.

Real-time environmental monitoring dashboard

Flood Early Warning Systems

Design and deliver integrated FEWS with observation networks, rainfall forecasts, hydrologic modelling and alert workflows — operationalised with three-tier triggers for civil agencies.

  • Bias-corrected rainfall forecasts
  • Coupled HEC-HMS / hydrodynamic models
  • Operator dashboards & SMS dispatch
IoT rain gauges and water level stations

Hydrological Monitoring & modelling

Basin-wide IoT networks of rain gauges, water-level stations, weather stations and soil moisture sensors — cloud-streamed for real-time and historical use.

  • Solar-powered field sensors
  • Cellular & satellite backhaul
  • Open APIs and operator portals
Urban flood risk mapping

Risk-Based Flood Management

Translate model output into risk scores, evacuation guidance, exposure analysis and mitigation scenarios — including building-level damage prediction.

  • Inundation depth × damage curves
  • 10 building types calibrated
  • Scenario & mitigation planning
Risk-based flood assessment mapping

Parametric Insurance Advisory

Validated triggers, underwriting data and event verification — closing the gap between underwritten risk and localized flood reality.

  • Localized triggers, sub-km resolution
  • Backtested against 2017 Colombo flood
  • Pilot support for Japanese insurers
Green stormwater infrastructure

Urban Stormwater & Green Infrastructure

Evaluate and optimise urban drainage, retention and green infrastructure for climate-adapted cities — grounded in hydraulic modelling and local rainfall regimes.

  • SWMM-based drainage analysis
  • Bioswales, trenches, retention
  • Climate-adjusted design storms
Real-time control system

Real-Time Control & Decision Support

Operations dashboards, automated thresholds and decision-support workflows — connecting forecasts to action across agencies, utilities and communities.

  • Threshold-driven alerts
  • Role-based operator views
  • Audit-grade event logs
Capabilities

Three-layer data fusion built for tropical flood regimes.

We fuse satellite, numerical weather model and ground IoT data — then bias-correct against decades of observed records — to deliver forecasts that hold up where coarse global products miss the event entirely.

  • JAXA GSMaP satellite precipitation
  • Numerical weather model ensembles
  • Ground IoT rain & water-level sensors
  • 22+ years of basin calibration
  • Sub-kilometre downscaling for urban risk
  • Damage functions for Sri Lanka, Thailand, Vietnam
22 + basins

Sri Lankan basins in active pipeline under the FAO Batticaloa programme.

Approach

From research-based modelling to operational flood resilience.

We combine decades of hydrologic expertise, environmental research partnerships and practical system engineering to support governments, insurers and communities in Sri Lanka and beyond.

  • Catchment hydrology, rainfall-runoff and floodplain hydraulics
  • Impact-based forecasting integrated with local operations
  • Bias correction, calibration and validation against observed data
  • Tailored capacity development for agencies and decision makers
Urban stormwater management infrastructure
Sub-km urban inundation modelling and green-infrastructure evaluation, calibrated to local rainfall regimes.
Leadership

Four decades of hydrology, in service of South Asian resilience.
