The New England Water Science Center collects data and does interpretive studies on hydrology, hydraulics, and water quality in cooperation with the Federal Highway Administration and State Departments of Transportation (DOTs) in New England and other states.
Hydrologic studies include efforts to measure and analyze streamflows to provide flood-flow estimates that are available in the on-line StreamStats applications. Hydraulic studies include efforts to quantify bridge scour, stream-channel geometry, and runoff timing variables. Water-quality studies include efforts to measure, analyze, and model the concentrations, flows, and loads of stormflows. Water-quality studies also include efforts to measure and analyze changes in groundwater quality associated with the construction and operation of the transportation infrastructure. The results of these efforts are designed to provide tools, techniques, and information that can be used by decisionmakers to meet the DOTs missions to provide a transportation infrastructure that is safe, reliable, robust, and resilient while minimizing adverse effects on the environment.

Knowledge of the magnitude and frequency of floods is needed for the effective and safe design of bridges, culverts, and other structures. This information is also important for flood-plain planning and management. Periodic examination of flood-frequency characteristics is essential to ensure the best estimates of flood magnitudes for a given annual exceedance probabilities (AEP).SELDM: Stochastic Empirical Loading and Dilution Model - Project page

Comparison of SELDM simulated total-phosphorus concentrations with ecological impervious-area criteria
Ecological studies indicate that impervious cover (IC) greater than approximately 5%–20% may have adverse effects on receiving-stream ecology. It is difficult to separate the effects of runoff quality from other effects of urbanization on receiving streams. This study presents the results of a numerical experiment to assess the effects of increasing IC on water quality using the Stochastic EmpiricCharacterization of stormwater runoff from bridge decks in eastern Massachusetts, 2014–16
The quality of stormwater runoff from bridge decks (hereafter referred to as “bridge-deck runoff”) was characterized in a field study from August 2014 through August 2016 in which concentrations of suspended sediment (SS) and total nutrients were monitored. These new data were collected to supplement existing highway-runoff data collected in Massachusetts which were deficient in bridge-deck runoffSimulating runoff quality with the highway-runoff database and the Stochastic Empirical Loading and Dilution Model
Stormwater practitioners need quantitative information about the quality and volume of highway runoff to assess and mitigate potential adverse effects of runoff on the Nation’s receiving waters. The U.S. Geological Survey developed the Highway Runoff Database (HRDB) in cooperation with the FHWA to provide practice-ready information to meet these information needs on the local or national scale.

Streamflow statistics are needed by decision makers for many planning, management, and design activities.
