Urban geology database for the Omaha area:
Mass wasting and accelerated erosion sites.
Description of project:
This is a undergraduate research project completed by Kirk Heim and Matt Jacobs under the advisement of Harmon Maher, at the Dept. of Geography and Geology, University of Nebraska at Omaha. Partial funding was provided to Kirk and Matt by the University Committee on Research. The project documents sites of mass wasting and accelerated erosion in the Omaha area. Field work concentrated on construction sites, drainage networks, steep slopes, retaining walls and road cuts and other sites of potential slope failure and erosion. A standardized data sheet was filled out, a digitial image taken of the feature, and the location noted on a U.S.G.S. topo map, and recorded with a hand-held GPS unit.
This web site is a pilot project exploring the possibility of establishing a larger, multi-layered urban geology data-base for the Omaha area. Examples of other layers of information to be generated in the future include geologic maps and depth to ground water.

Appropriate use of this database:
This site has the potential for being used for both educational and technical purposes. In the education venue, it can be used as a virtual field trip to the environmental geology of the Omaha area. On the technical side it has the potential to be used by geologists, engineers, city planners and others to obtain information on the geology of a specific site or area. However, given that this project involves undergraduate work, and is in on a shoestring budget, the user of this database is responsible and liable for the appropriate use of any of this data. You must corroborate the information yourself. We make no assurrances as to the accuracy of this data.
How to use database:
Below is an index to the various components of the database. The data is arranged by U.S.G.S. 7.5 minute topographic quads that cover the area, as depicted in the figure below. The Loveland and Omaha North quads have been completed as of 9/97. The links for the quads below will send you to an index map of the quad with numbered sites. Sites with summary information are listed below and are linked to individual data sheets and images of the mass wasting or accelerated erosion feature. Some additional components of the data base are included below.
