* Indicates a historical model that is not readily available to the public. Most historical model were developed or supported by federal agencies.
We specialize in numerical modeling of surface water and groundwater.
HWR’s 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, R, 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.
