Storm Damage - Sr-57 June 2008, Dale Sedler, Mark Bailey Mar 2016

Storm Damage - Sr-57 June 2008, Dale Sedler, Mark Bailey

Purdue Road School

A review of the impact of the White River leaving its watershed and destroying a box culvert under SR-57 in Greene County, IN. Includes discussion about impact of illegal levee, and photos and discussion on contraction scour.


Gis Tools For Hydrology And Hydraulics, David D. Finley Mar 2015

Gis Tools For Hydrology And Hydraulics, David D. Finley

Purdue Road School

GIS information sources used by the Office of Hydraulics to improve the accuracy and efficiency hydrologic computations will be presented. A variety of information sources will be discussed with an emphasis on DEM data obtained from Indiana's recent state-wide mapping initiative. Sources and limitations of the data will be discussed, and techniques for utilizing this data will be introduced.


A Wind-Derived Upwelling Index For Lake Michigan, Stephen B. Davis, Rebecca Essig, Cary Troy Aug 2014

A Wind-Derived Upwelling Index For Lake Michigan, Stephen B. Davis, Rebecca Essig, Cary Troy

The Summer Undergraduate Research Fellowship (SURF) Symposium

Coastal upwelling is a phenomenon that occurs along coastlines throughout the world, and has been shown to be strongly correlated with large fish populations in these areas. Coastal upwelling occurs when strong coastal winds drive water transport away from the coast, causing colder, often nutrient-rich water to upwell in its place. While coastal upwellings can be detected with satellite imagery or in situ temperature measurements, these datasets are neither continuous nor long-term. A wind-derived upwelling index was created for Lake Michigan to continuously quantify upwellings over multiple decades, and to allow for further understanding of the impact of upwelling in …


Modeling Target Disinfection By-Product Dynamics In Indoor Swimming Pools, Barnard S. Mondal, Cary Troy, Mehrnaz Afifi, Shih-Chi Weng, Ernest R. Blatchley Iii Oct 2013

Modeling Target Disinfection By-Product Dynamics In Indoor Swimming Pools, Barnard S. Mondal, Cary Troy, Mehrnaz Afifi, Shih-Chi Weng, Ernest R. Blatchley Iii

The Summer Undergraduate Research Fellowship (SURF) Symposium

Chlorination is the primary disinfection method for swimming pools in the United States; however, chlorine also reacts with pollutants (e.g., sweat, urine and anthropogenic compounds) to form disinfection by-products (DBPs). Some DBPs are asthma causing (e.g. nitrogen-trichloride) and even carcinogens (e.g., trihalomethanes and nitrosamines). Consequently, exposure to DBPs poses health risks to patrons and staff in pool environments. Furthermore, volatilization of DBPs is enhanced by bather activity, but the relationship between activity and volatilization has yet been quantified such that the dynamic behavior of DBPs can be predicted. Therefore, the objective of this research is to …


Deep-Water Near-Bottom Turbulence In Lake Michigan: An Underwater Investigation, David J. Cannon, Cary Troy Oct 2013

Deep-Water Near-Bottom Turbulence In Lake Michigan: An Underwater Investigation, David J. Cannon, Cary Troy

The Summer Undergraduate Research Fellowship (SURF) Symposium

Motivated by a need to characterize near-bottom deep-water turbulence for an understanding of the filtration capabilities of invasive quagga mussels, an instrument tripod was deployed in Lake Michigan for six months in 60m of water to measure current velocities, with specific interest being paid to near-bottom (0.10 to 0.95 meters above bottom) velocities during the deployment. The deployment period (September 2012-April 2013) was characterized by very little stratification and a median temperature of about throughout the water column. A mean horizontal velocity of 3.6 cm/s with a standard deviation of 2 cm/s was also measured at 1 meter above the …
