Scour in Cohesive Soils/Ex-Situ Scour Testing Device

DESCRIPTION: The study addresses the incipient erosion of cohesive soils. Scour on cohesive soils is a very complex phenomenon that is not completely understood. A special erosion apparatus (ex situ scour testing device) was developed to apply hydraulic loading on cohesive soil samples.

Influence of Large Scale Turbulence Structures on Scour in Cohesive Soils

DESCRIPTION:The study will address the influence of large-scale turbulence on the erosion process of soils. Large-scale turbulence structures play an important role in the bridge pier scour process. To simulate the turbulent hydraulic loading, a dual-drive wave making tube will be constructed, where soil samples will be exposed to oscillating hydraulic loads.

Improved Hydraulic Safety of Covered Bridges

DESCRIPTION: This research will assess the hydrodynamic vulnerability of covered wooden bridges, taking into account covered bridge designs and framing, and assess the hydrodynamic loading for partially and fully submerged flow conditions. Physical and Computational Fluid Dynamic (CFD) modeling will be used to study the hydrodynamic vulnerability.

Smart Scour Countermeasures

DESCRIPTION: The objective of this study is to investigate new concepts to monitor the performance of bridge scour countermeasures. The scour countermeasure monitoring is needed for increasing confidence in field installations. Various forms of armoring countermeasures will have embedded active/passive sensors, which will be used for monitoring the countermeasures' position.

Wave/Tsunami Wave Bridge Deck Response Forces

DESCRIPTION:This study will determine hydrodynamic wave/tsunami wave drag, wave/tsunami lift forces, and wave/tsunami wave moments from bridge deck response for partially and entirely submerged bridge decks. The bridge decks will be mounted on a 2-degree-of-freedom bridge deck response system consisting of guide system allowing a free horizontal and vertical response of bridge deck models.

Computational Fluid Dynamics (CFD) Modeling and Computational Multi-Physics Modeling (CMM) to Analyze Hydraulic Hazards

DESCRIPTION: Develop or further develop CFD and CMM analysis procedures that include analysis of flood and wave forces on bridges; scour around bridge foundation structures, individually and in combination; scour countermeasures; bridge designs that minimize vulnerability to scour; culvert analysis, including flow losses in different culvert barrel geometries and surfaces; ease of fish passage; effects of bed material on scour, including cohesive sediment and sediment of varied size; effects of debris on scour; live bed scour; and other processes that may impact the safety of the transportation system or minimize adverse affects of the transportation system on the environment.

Hydraulic Performance of Shallow Foundations for Support of Bridge Abutments

DESCRIPTION: With this research study, the Federal Highway Administration (FHWA) will revisit and attempt to clarify conflicting guidance. The Turner-Fairbank Highway Research Center (TFHRC) J. Sterling Jones Hydraulics Research Laboratory will test the hydraulics performance of typical shallow foundation abutment structures with vertical walls (e.g. Geosynthetic Reinforced Soil abutments) and sloping spill through abutments. The hydraulics performance tests of the abutment structures will include scour, scour protection, and hydrodynamic loads.

In Situ (Field) Scour Potential Testing Device TPF-5(210)

DESCRIPTION:This study will research the feasibility of using a scour testing field device (in situ scour device) to determine the erodibility of soils around bridge foundations. An effective in situ scour testing device could provide assistance on a project-by-project basis. Such a field device could more accurately define the scour potential for a given set of hydraulic design conditions.

Bridge Pier Scour Research TPF-5(211)

DESCRIPTION: The scope of work consists of researching identified bridge pier scour issues to predict scour and to improve scour prediction equations. The research will be based on a combination of data obtained from the historical scour research literature, laboratory experiments, field testing, data collection, and data evaluation. The TFHRC J. Sterling Jones Hydraulics Research Laboratory will collaborate on this proposed research and will provide laboratory capabilities and technical assistance.

Updating U.S. Precipitation Frequency Estimates for the Northeastern Region TPF-5(249)

DESCRIPTION: The purpose of this study is to update the rainfall maps for MA, ME, NH, NY, RI, and VT, and to determine annual exceedance probabilities (AEP) and average recurrence intervals (ARI) for durations ranging from 5 minutes to 60 days and for ARIs from 1 to 1,000 years. The updates will be published as subsequent volumes of the Department of Commerce's (DOC's) National Oceanic and Atmospheric Administration (NOAA) Atlas 14.
