Assessing the Impacts of Closing the River Gulf Grain Company on Local Producers of Corn and Soybeans

Hotelling’s classic model of spatial competition is used to estimate the impacts on price of the closure of one of three grain buyers on the Mississippi River in the vicinity of Scott County, Iowa. The customers of the buyer who is closing (River Gulf Grain Company) in Davenport, Iowa, are assumed to deliver their grain to a buyer in either Buffalo, Iowa, to the south or to a buyer in Clinton, ...

Evaluating Red Light Running Programs in Iowa

As communities across the United States attempt to address red light running (RLR), a number of them have implemented RLR camera-enforcement programs. Since 2004, three Iowa communities—Davenport, Council Bluffs, and Clive—have implemented RLR camera-enforcement programs. The objective of this research was to evaluate the effectiveness of RLR cameras in these three Iowa communities. A reduction...

Quaternary Geology of the Detroit, Michigan Quadrangle and Surrounding Areas

A preliminary 1:24,000 scale surficial geologic map of the Detroit 7.5 minute topographic quadrangle, and surrounding areas, was produced to serve as a framework for future urban site assessment. The results show that the map area is a relict late Pleistocene glacial landscape on which is superimposed a Holocene system of streams, lakes and wetlands, and an Anthropocene landscape of manufacture...
