Practice areas

Three integrated service lines with a strong technical core.

Onyx Moorland combines technical engineering, environmental due diligence, and software-enabled decision intelligence for infrastructure, environmental, financial, and institutional clients.

01 / Morpho-hydrodynamic modeling

Hydraulic, hydrologic, and sediment systems analysis

Technical support for flow, flood, scour, channel response, and infrastructure performance under planning and design scenarios.

  • Open-channel hydraulics and flow analysis.
  • Sediment transport, morphodynamic analysis, and quasi-unsteady workflows.
  • Coastal and riverine flood-risk modeling for infrastructure decisions.
  • Bridge, levee, channel stability, and scour evaluation.
02 / Environmental due diligence

Phase I and Phase II review support

Environmental screening, records review, site assessment planning, and risk framing for transactions, lending, and compliance-sensitive projects.

  • Initial Site Assessment and Phase I support.
  • Preliminary Site Assessment and Phase II planning.
  • Hazardous materials and environmental records review.
  • Permitting and regulatory context evaluation.
03 / QuantisNexis development

Decision intelligence, dashboards, and analytics

Applied software and analytical frameworks that extend engineering insight into governance, climate intelligence, and organizational resilience.

  • Quantis Index scoring and benchmarking logic.
  • Risk, resilience, and governance dashboards.
  • Climate and infrastructure intelligence modules.
  • Client-facing analytics and reporting prototypes.
Technical capabilities

Focused engineering support for complex water and environmental systems.

The firm emphasizes technically defensible, transparent, and practical engineering solutions appropriate for planning-level studies, regulatory support, and engineering decision-making.

H&H modeling

Flow, floodplain, conveyance, drainage, and infrastructure evaluation for riverine and engineered systems.

Sediment and morphodynamics

Assessment of erosion, deposition, sediment mobility, and long-term channel response.

Scour analysis

General scour, local scour, pier scour, abutment scour, and levee or channel protection review.

FEMA and USACE studies

Support for levee certification, authorized channel capacity review, and planning-level technical documentation.

GIS and engineering data

Spatial analysis, records interpretation, technical screening, and geospatial context for engineering decisions.

Environmental permitting

CEQA/NEPA-aware technical review, compliance framing, and study coordination support.

Recent support focus

Sediment transport and scour evaluations for levee certification and authorized channel capacity studies.

Recent support efforts focus on sediment transport, scour evaluation, hydraulic capacity, and infrastructure resilience studies for agencies, consultants, and multidisciplinary project teams.

  • Long-term sediment transport simulation methodologies using HEC-RAS.
  • Sedi-graph development for quasi-unsteady simulations and scenario testing.
  • Sensitivity analysis frameworks for uncertainty in gradation and transport assumptions.
  • Integrated hydraulic, sediment mobility, and scour assessment for resilient infrastructure planning.
