Deltares USA Inc.

Deltares USA Inc., a Silver Spring, Maryland–based tax-exempt non-profit research institute, delivers hydrodynamic and coastal modeling software, training, and water-resource infrastructure support services to federal agencies primarily as a prime contractor (86% of recent awards), competing full-and-open with no set-aside designation.

The organization specializes in numerical modeling for water availability prediction, coastal morphodynamics, and flood-risk assessment. Deltares USA operates Delft3D, a specialized hydrodynamic and sediment-transport modeling suite licensed to federal agencies, and provides technical support, software architecture, and research services around groundwater and surface-water modeling platforms (MODFLOW-6, Delft3D, XBeach). Representative prime contract work includes a $6.63 million time-and-materials definitive contract from the National Oceanic and Atmospheric Administration (NOAA) for Community Hydrologic Prediction System infrastructure and support services running through November 2032, a $49.3 thousand sole-source purchase order from the Army Corps of Engineers for a Delft3D Stand Alone License and support services, and a $30 thousand purchase order from the Corps for a five-day Delft3D training course in Jacksonville, Florida. As a subcontractor, Deltares USA delivers coastal modeling support to Raytheon Company (on a NextGen Water Prediction Capability sub task) and to the University of Delaware (providing BEWARE runup prediction model setup and PhD student supervision under an Environmental Security Technology Certification Program project).

Customer concentration is high and skewed toward civil-works and water-science agencies. NOAA accounts for 9 awards carrying $10 million in combined potential value — substantially higher than the remaining customer base. The U.S. Geological Survey, the Office of Naval Research, and the Army Corps of Engineers follow in award count. NOAA's dominance reflects Deltares USA's established position in coastal storm modeling and hydrodynamic infrastructure; DHS Science and Technology Directorate's single award carries $1.9 million in potential value, but NOAA's portfolio remains the strategic anchor.

Federal grant work is substantial and recurring. Deltares USA holds cooperative agreements as prime recipient under the USGS Research and Data Collection program (CFDA 15.808), the USGS non-competitive assistance program (Sacramento Acquisition Branch), the Army Corps of Engineers Basic, Applied, and Advanced Research in Science and Engineering program (CFDA 12.630), NOAA's research programs, and the Office of Naval Research. Recent grant work includes a $125.8 thousand cooperative agreement from the Army Corps of Engineers to develop nature-based solutions for water resource management through hydrodynamic and morphodynamic modeling (performance at Silver Spring), a multi-year USGS cooperative agreement on advancing modeling capacity for the water enterprise centered on MODFLOW-6 software architecture and parallel computing enhancement, and a USGS collaborative agreement (spanning 2024–2029) supporting operational modeling of coastal storm systems in California and estuaries including the Columbia River and San Francisco Bay. Deltares USA also holds sub-award positions on University of Alaska Fairbanks–led grants (Alaska Coastal Cooperative for Co-producing Transformative Ideas and Opportunities in the North, AC3TION) beginning in FY2024.

Service Contract Inventory records show modest federal services footprint: SCI-reported invoicing of $2.9 million across FY2022–FY2025, with government-paid median hourly rates around $229.89/hr and senior labor pricing through $243.51/hr. Across SCI-reportable prime contracts, subcontractors performed roughly 56% of total contractor hours, with nine named subs reported. The FTE trajectory in SCI shows roughly 0.5 to 0.8 FTEs delivered annually to the federal government in the services contracts above the $150,000 reporting threshold; this figure excludes the larger NOAA and USGS cooperative agreements, which carry time-and-materials or cooperative-agreement pricing structures outside the traditional labor-hour SCI reporting model.

Award activity averaged less than one per year over the past five years (2022: 1; 2023: 5; 2024: 5; 2025: 3; 2026: 2 to date), with recompete exposure modest: two awards with ultimate completion dates in the next twenty-four months carry combined potential value of $49 thousand. The organization's competitive footprint remains concentrated in the water-resource and coastal-resilience domain; no parent GWACs or large vehicle seats appear in the portfolio beyond a single Multiple Award Schedule task order. Deltares USA's positioning is anchored to specialized hydrodynamic modeling capability and to established research partnerships with USGS and NOAA stretching back over a decade.
