Our services

Modeling, forecasting, evidence.

We do the science, answer the question, and build the systems that keep answering it.

01Flood risk modelingHow deep, how often, and how sure.
01

Flood risk modeling

  • Coastal surge and wave modeling
  • Riverine, pluvial and compound events
  • Return-period surfaces and depth rasters
  • Model archive: mesh, forcing, control files

ADCIRC · SWAN · HEC-RAS · SFINCS · Delft3D

Where it stopsA 100-year surface is a statistical statement, not a promise.

02Forecast and early warningRuns on a schedule, without anyone watching.
02

Forecast and early warning

  • Deployed chains with scheduling and monitoring
  • Threshold catalogue and escalation logic
  • Runbook covering every known failure mode
  • Back-test: skill, hits, false alarms, lead time

GFS · ECMWF · ERA5 · Parametric TC · HPC / cloud

Where it stopsEvery threshold trades false alarms against missed events. Nothing avoids both.

03Machine learning and visionTrained against physics, scored against ground truth.
03

Machine learning and vision

  • Flood extent from Sentinel-1 SAR
  • Surrogate models for rapid screening
  • Structure inventories from imagery
  • Accuracy assessment against withheld data

PyTorch · Sentinel-1 SAR · Sentinel-2 · Segmentation

Where it stopsImagery gives extent, not depth. Depth still comes from physics.

Discuss
04Validation and reviewA second opinion, and the numbers behind it.
04

Validation and review

  • Station-by-station skill assessment
  • Independent review of an existing study
  • Reproduction package: scripts, forcing, configuration
  • A clear position on fitness for purpose

Python · Fortran · OceanMesh2D · NOAA CO-OPS · NDBC · USGS

Where it stopsSkill against gauges says nothing where there are none, which is usually where the exposure is.

05Aquaculture sitingTurning idle land into working ponds, on paper first.
05

Aquaculture siting

  • Scoping unused land for fish and shrimp ponds
  • Water supply, drainage and salinity at the site
  • Flood and storm exposure of ponds and pens
  • Intake, outfall and water exchange layout

HEC-RAS · SFINCS · ADCIRC · SWAN

Where it stopsWater and layout are what we settle here. Soil, permits and market access decide as much, and sit outside this scope.

Discuss
06Project impact on farmsWhat a new project will change at the farms around it.
06

Project impact on farms

  • Water conditions at farms, before and after
  • Salinity and temperature change at intakes
  • Changes to flooding and drainage around ponds
  • The water chapter of an EIS or EA

Delft3D · ADCIRC · SWAN · HEC-RAS

Where it stopsA before-and-after answer is only as good as its baseline. Where nothing was measured before the project, that is the honest limit of it.

Where we work

Regions, and the physics behind each one.

Areas of active work and interest — not a claim that a system is running in each.

Global coastal water level reanalysis

A physics-based reanalysis of coastal water levels worldwide, built by simulating more than 350 historical events — supplying the coastal boundary for a compound flood risk framework.
