Improving Woody Biomass Estimation Efficiency Using Double Sampling, David L. Parrott, John M. Lhotka, Songlin Fei, B. Scott Shouse May 2012

Improving Woody Biomass Estimation Efficiency Using Double Sampling, David L. Parrott, John M. Lhotka, Songlin Fei, B. Scott Shouse

Forestry and Natural Resources Faculty Publications

Although double sampling has been shown to be an effective method to estimate timber volume in forest inventories, only a limited body of research has tested the effectiveness of double sampling on forest biomass estimation. From forest biomass inventories collected over 9,683 ha using systematic point sampling, we examined how a double sampling scheme would have affected precision and efficiency in these biomass inventories. Our results indicated that double sample methods would have yielded biomass estimations with similar precision as systematic point sampling when the small sample was ≥ 20% of the large sample. When the small to large sample …


Development And Deployment Of A Bioreactor For The Removal Of Sulfate And Manganese From Circumneutral Coal Mine Drainage, C. B. Mastin, J. D. Edwards, Christopher D. Barton, Anastasios D. Karathanasis, Carmen T. Agouridis, Richard C. Warner Jan 2012

Surface mining, in the form of contour mining and mountain-top removal, is a common means for retrieving coal in the Appalachian Coal Belt region of Kentucky. Overburden or excess spoil generated by these two methods is placed in valley fills. Traditionally Constructed fills have been shown to adversely impact headwater ecosystems via stream burial and through alterations to the hydrology, sediment supply, water quality and biological composition of downstream reaches. Mine drainages emanating from the toe of valley fills often contain elevated levels of total dissolved solids and heavy metals. Drainage chemistry from Guy Cove, a valley fill located in …


Model Ordinance For Development On Karst In Kentucky: Guidance For Construction On Karst Terrain And The Reduction Of Property Damage And Threat To Human Health Resulting From Karst Geologic Hazard, James C. Currens Jan 2012

Model Ordinance For Development On Karst In Kentucky: Guidance For Construction On Karst Terrain And The Reduction Of Property Damage And Threat To Human Health Resulting From Karst Geologic Hazard, James C. Currens

Information Circular--KGS

I have dealt with hundreds of incidents of karst-related geohazards; some have caused major damage to buildings and infrastructure. Although cases are largely limited to the ground surface being made unusable, a significant number of structures are damaged by karst flooding or cover collapse each year, which is devastating to families who have lost their homes. Most of these events should never have happened, because the karst hazard could have been avoided by selecting a better building site or designing the building to withstand the damage from the hazard. Furthermore, most of the planning authorities I have had experience with …


Characteristics Of Kentucky Agricultural Operations Participating In Nrcs Conservation Programs, Carmen T. Agouridis Jan 2012

Characteristics Of Kentucky Agricultural Operations Participating In Nrcs Conservation Programs, Carmen T. Agouridis

MPA/MPP/MPFM Capstone Projects

The Natural Resource Conservation Service (NRCS) designs and promotes a wide variety of conservation practices and programs that enhance the environment by reducing soil erosion, improving water quality, and enhancing and creating wildlife habitat. The impact of these practices and programs is largely dependent on the voluntary participation of landowners. Thus, central to the success of the NRCS conservation programs is an understanding of the characteristics of landowners and operations participating in these programs.

Using operator and operation characteristics from the 1997, 2002, and 2007 Censuses of Agriculture and controlling for county fixed effects, this study 1) identifies significant characteristics …

Water Quality Trading Markets For The Kentucky River Basin: A Point Source Profile, Ronald Childress Jr. Jan 2012

Water Quality Trading Markets For The Kentucky River Basin: A Point Source Profile, Ronald Childress Jr.

Theses and Dissertations--Agricultural Economics

This study assessed the feasibility and suitability of a Water Quality Trading (WQT) program within the Kentucky River Basin (KRB). The study’s focal point was based on five success factors of a WQT program: environmental suitability, geospatial orientation, participant availability, regulatory incentive, and economic incentive. The study utilized these five success factors, geographical characteristics, and Discharge Monitoring Reports (DMR) to assess the feasibility of a WQT program.

The assessment divided the KRB into five eight digit Hydrologic Unit Codes (HUC), North, Middle, and South Fork, Middle Basin, and Lower Basin, to determine regional impacts caused by the nutrient PSs. Individual …
