Our Services

Our extensive experience includes:

  • Hydrologic and hydraulic studies
  • Coastal modeling
  • Sediment transport modeling
  • Thermal discharge studies
  • Mixing zone studies
  • Stormwater management
  • Hydrogeology
  • Fate and transport modeling

We specialize in numerical modeling of surface water and groundwater. Our work has been a part of flood studies, environmental impact assessments, NPDES permitting, TMDL studies, mixing zone requests, 316a demonstrations and variances, joint permit applications, state-level permitting, environmental remediation, and testimony.

Our programming expertise helps to set us apart from other professionals in our field. We are fluent in Python, Matlab, VBA, Javascript, and HTML. We differentiate ourselves by combining our modeling and technical expertise with our ability to efficiently access data and our skill at automating and performing state-of-the-art work. The more difficult the challenge, the more useful we are.
