Leaf Optical And Indirect Lai Measurements In Wheat And Alfalfa At Maciv: Agmet Progress Report 89-4, E. A. Walter-Shea, B. L. Blad Jan 1989

Leaf Optical And Indirect Lai Measurements In Wheat And Alfalfa At Maciv: Agmet Progress Report 89-4, E. A. Walter-Shea, B. L. Blad

School of Natural Resources: Documents and Reviews

Interpretation of remotely sensed vegetative surfaces requires an understanding of the interaction of radiation with the various components of vegetation. Leaves are the most important component. Thus it is important to know the optical properties of individual leaves as well as the amount and distribution of leaves making up the vegetative cover. The objectives of our study were 1) to characterize the reflectance from and transmittance through adaxial and abaxial surfaces of individual wheat and alfalfa leaves and 2) to compare the traditional, time-consuming, destructive method of estimating LAI (direct method) to a relatively quick, indirect estimate of LAI in …

A Preliminary Study Of The Hydrogeology Of The Dakota Formation In Douglas, Sarpy And Washington Counties, Eastern Nebraska, Thomas Mark O'Connor Aug 1987

A Preliminary Study Of The Hydrogeology Of The Dakota Formation In Douglas, Sarpy And Washington Counties, Eastern Nebraska, Thomas Mark O'Connor

School of Natural Resources: Dissertations, Theses, and Student Research

This study provides preliminary information on the hydrogeology of the Dakota Formation within a 1,000 square-mile area in eastern Nebraska. Isopach maps of the Dakota Formation and individual sand and gravel beds were constructed using a computer contouring program. Hydraulic conductivity values for water-bearing sand beds in the Dakota were estimated using the equation for calculating the specific capacity of wells and results from a grain-size analysis. Concentrations of major dissolved species were determined for samples collected from twenty five wells. The Dakota Formation is characterized by an increase in thickkness and an increase in percentage of clay versus sand …

Development Of Oriented Lakes In The Eastern Rainbasin Region Of South Central Nebraska, James P. Krueger Jan 1986

Development Of Oriented Lakes In The Eastern Rainbasin Region Of South Central Nebraska, James P. Krueger

School of Natural Resources: Dissertations, Theses, and Student Research

The Eastern Rainbasin region is located on a relatively flat-lying, loess-covered plain. The gently sloping land surface is poorly drained and in places local drainage is toward basins which lack external drainage. In the spring, excell precipitation collects in these basins, forming small lakes and marshes. It is these ephemeral lakes that give the region its name.
