Research Brief: Prioritizing Resilient Retrofits
(2018-02)2017 was one of the most devastating U.S. hurricane seasons ever recorded. State Departments of Public Safety across the country list tens of thousands of destroyed homes and hundreds of thousands more damaged. Although ... -
Research Brief: Quantifying the impact of pavement reflectivity on radiative forcing and building energy demand in neighborhoods
(2017-03-13)Albedo is the measure of the fraction of solar energy reflected by the Earth’s surface. High-albedo surfaces, which are lighter in color, absorb less sunlight energy and reflect more shortwave radiation. The change in ... -
Research Brief: Simulating the Formation of ASR Gels
(2019-04)Alkali-silica-reaction (ASR) is a significant cause of premature concrete deterioration. Although it has received much research attention, an essential question still remains—how does a soft gel, as is formed by this ... -
Research Brief: The Influence of Incorporating Uncertainties and Treatment Path Dependence in Performance-based Planning Analyses
(2018-11)According to the American Society of Civil Engineers (ASCE) 2017 Infrastructure Report Card, the backlog for repair of existing highways across the U.S. totals approximately $420 million. With funding at all-time lows, it ... -
Research Brief: The Role of Pavements in Meeting GHG Reduction Targets
(2019-08)To meet the targets for reducing greenhouse gas (GHG) emissions set by cities and states, several solutions have been proposed including renewable energy production, subsidies for electric vehicles, and carbon taxes. ... -
Research Brief: Validation of Molecular Dynamics-Based Structural Damage
(2019-03)Windstorms currently generate $28 billion in average annual damage and this figure is projected to potentially rise to $38 billion by 2075. Traditional engineering approaches that analyze the resilience of structures fail ... -
RFID: An Incomplete Saga
(2000)Basic introduction to automatic identification and enterprise resource planning software (SAP). -
Risk in the Global Supply Chain
(2006)Carbon footprints are not on the priority list of risk analysts in operations management for at least half or more of global businesses. What are the other risks in the global supply chain? -
Salinity Effects on Velocity Distributions in an Idealized Estuary
(Cambridge, Mass. : Dept. of Civil Engineering, Massachusetts Institute of Technology, 1962-01)An experimental and analytical investigation of the two-dimensional (i.e. longitudinal and vertical) convective-diffusion processes in an idealized laboratory estuary. The estuary is idealized to obtain steady-state salinity ... -
A Scientific Investigation into Concrete Pavement Durability
(MIT Concrete Sustainability Hub, Oregon State University, University of New Brunswick, 2021-01)Although concrete pavements offer many long-term performance benefits, there are still instances where premature degradation of pavements leads to unexpected and costly repairs. In addition to being a burden to transportation ... -
A Second-order Budyko-type Parameterization of Landsurface Hydrology
(Cambridge, Mass. : Ralph M. Parsons Laboratory, Hydrology and Water Resource Systems, Massachusetts Institute of Technology, Dept. of Civil Engineering, 1982-06)This work develops a simple, second-order parameterization of the water fluxes at a landsurface for use as the appropriate boundary condition in general circulation models of the global atmosphere. The derived parameterization ... -
Secondary Motion and Turbulence in Circular Couette Flow
(Cambridge, Mass. : Hydrodynamics Laboratory, Dept. of Civil Engineering, Massachusetts Institute of Technology, 1966-07)The flow in an annular space between two separately rotating cylinders of finite length is investigated. It is found that when the outer cylinder rotates faster than, and in the same direction as, the inner cylinder, the ... -
Sediment Transport in the Coastal Environment
(Cambridge, Mass. : Ralph M. Parsons Laboratory for Water Resources and Hydrodynamics, Dept. of Civil Engineering, Massachusetts Institute of Technology, 1976-01)The subject of sediment transport in the coastal zone is investigated and the answers to some of the basic questions of sediment transport in unsteady, oscillatory flow are presented. By adopting Jonsson's (1966) results ... -

Simulation of Observed Topography Using a Physically-based Basin Evolution Model
(Cambridge, Mass. : Ralph M. Parsons Laboratory, Hydrology and Water Resources, Dept. of Civil Engineering, School of Engineering, Massachusetts Institute of Technology, 1994-10)This work presents a model for basin evolution and a procedure for estimating the parameters of this model to reproduce a given topography. The model is calibrated based on three measures: the slope-area relationship, the ... -
Simulation of Random Fields with the Turning Bands Method
(Cambridge, Mass. : Ralph M. Parsons Laboratory Hydrology and Water Resources Systems, Dept. of Civil Engineering, Massachusetts Institute of Technology, 1981-07)This report presents and extends the Turning Bands Method (TBM) for the synthetic simulation of random fields. Originally introduced by G. Matheron (1973) of the Ecole des Mines de Paris, the TBM can be applied to stationary ... -
Simulation of the Continuous Snowmelt Process
(Cambridge Ralph M. Parsons Laboratory for Water Resources and Hydrodynamics, Massachusetts Institute of Technology, 1972-01)The efficient design of many water management projects requires the ability to predict the time distribution of runoff from a melting snowfield. A continuous model of the snow accumation and melting processes is presented ... -
