Economic Valuation of River Systems

Edited by Fred J. Hitzhusen

The book applies benefit–cost analysis and a wide array of non-market and distribution economic valuation methods in ecologic context to determine the pay-off and distribution impacts of various infrastructure and water quality improvements to eight river systems in the Great Lakes region of the US. The generally positive results have important implications for public policy and future research.

Chapter 10: An Economic Analysis of Lower Great Miami River Segment Improvements

Radha Ayalasomayajula, P. Wilner Jeanty and Fred J. Hitzhusen


Radha Ayalasomayajula, P. Wilner Jeanty, and Fred J. Hitzhusen INTRODUCTION The Great Miami River Watershed is located in the southwest region of Ohio. The Great Miami River is 155 miles in length, and its watershed includes all or part of 15 counties with the headwaters in Hardin and Auglaize counties and the mouth in the Ohio River in Hamilton County. Interstates 70 and 75, two of the nation’s longest Interstate highway systems, intersect just north of Dayton. Dayton, with a population of 190 000, is the largest city within the watershed. Other major cities within the watershed exceeding 50 000 populations include Springfield, Hamilton, and Middletown. There are 2360 miles of rivers and streams in the Great Miami River Watershed. Water quality in and recreational access to the watershed’s rivers and streams have been concerns over the last 20 years. Evaluation of fish and macroinvertebrate community performance in streams and rivers draining the Great and Little Miami River Basins indicates that most streams meet basic aquatic-life-use criteria set by the Ohio Environmental Protection Agency (EPA) for warm water habitat. According to the Ohio EPA, the Lower Great Miami and Whitewater River Watershed is impaired primarily by nutrient enrichment and habitat alterations. Over 80 percent of the river miles are impaired by nutrient enrichment and 40 percent by other habitat alterations. Such severe river and stream impairments commonly result from human development, inadequate agricultural practices and land use changes in the surrounding area. Gravel mining is included in this category,...
