The Illinois Center for Transportation at the University of Illinois has released a report that outlines the activities of the Erosion and Sediment Control Research and Training Center, which provides training and research for stormwater management practices, erosion prevention, and sediment control.

The Washington State Department of Transportation has released a report that provides a reference for geotechnical engineers and hydrogeologists on designing horizontal drainage systems to improve slope stability.

The Louisiana Transportation Research Center has released a report that evaluates the applicability of the Federal Highway Administration’s Hydraulic Engineering Circular documents method to Louisiana bridges situated on cohesive soils as a way to develop a design method for scour depth and scour rate prediction.

The New Zealand Transport Agency has released a report that presents an assessment of the New Zealand pre-tensioned concrete bridge stock and identifies bridges at risk of pre-tensioned reinforcement corrosion.

The Louisiana Transportation Research Center has released a report that discusses transport and treatability of particles and phosphorus in urban rainfall-runoff, the influence of hydrology on rainfall-runoff metal element speciation, and the toxicity of particulates in rainfall-runoff.

The Maryland Department of Transportation has released a report that develops preliminary specifications for high-quality pervious concrete suitable for use in Maryland State Highway Administration projects.

The Maryland State Highway Administration has released a report that evaluates the suitability of recycled concrete aggregate from road projects as bottom conditioning material for on-bottom oyster aquaculture in the Chesapeake Bay.

TRB’s Transportation Research Record: Journal of the Transportation Research Board, No. 2309 consists of 20 papers that examine weathered steel beam guardrails; longitudinal barriers struck by large trucks; continuous speed profile models for two-lane rural roads; integrating context-sensitive solutions into design–build programs; characterization of stormwater runoff; comparison of crash test ...

TRB’s National Cooperative Highway Research Program (NCHRP) Report 734: Hydraulic Loss Coefficients for Culverts explores culvert designs that maintain natural velocities and minimize turbulence to allow migratory species to pass through the culvert barrel. The report describes the refinement of existing hydraulic relationships and the development of new ones for analysis and design of culverts...

The U.K.’s Transport Research Laboratory has released a report that investigates technologies suitable for continuous monitoring of non-pressurized tubular structures, with a focus on surface water highway drainage systems. The report is available online without a fee after logging into the website.
