Cell identification, verification, and classification using shape analysis techniques
(University of Missouri--Columbia, 2007)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] The use of object-oriented approaches in both the verification of meteorological variables (especially precipitation) and the short-term forecasting ...
Methods for high-resolution soil-landscape modeling in midwest upland landscapes
(University of Missouri--Columbia, 2008)
Traditional soil mapping concepts do not sufficiently address the spatial resolution of some soil management problems. Continuous models of soil profiles and landscapes are needed to move beyond the categorical paradigm ...
Analysis of twenty-five years of heavy rainfall events in the Texas Hill Country
(University of Missouri--Columbia, 2008)
Forecasting heavy rain events and the area of greatest threat has been a long standing challenge in operational meteorology. This is especially true in certain regions where the physical geography lends itself to the ...
The verification of weather forecasts compared to numerical model guidance, climatology, human forecasts and seasonal variations
(University of Missouri--Columbia, 2011)
The accuracy of weather forecasts has been a topic of discussion for many years, and a simple but useful method for showing forecast accuracy has been an issue for meteorologists over time. My study on the comparison of ...
Climatology of atmospheric blocking 1978-2008 : global and hemispheric breakdown, as well as impacts of temperature, and global climate cycles
(University of Missouri--Columbia, 2010)
An examination of atmospheric blocking from the years 1978-2008 was conducted to explore the impacts of temperature and climate cycles on blocking intensity, blocking duration, and total blocking events on an annual basis. ...
Enhanced rhizodegradation of munitions explosives and degradates by selected native grass species
(University of Missouri--Columbia, 2010)
TNT (2,4,6-trinitrotoluene) and RDX (hexahydro-1,3,5-trinitro-1,3,5-triazine) are the two most widespread explosives in the world. The manufacture, use and disposal of explosives can result in environmental contamination, ...
Effects of veterinary antibiotics on atrazine degradation in soil
(University of Missouri--Columbia, 2014)
The release of veterinary antibiotics (VAs) in the environment is concerning because VAs have been linked to the development of antimicrobial resistant bacteria and may influence nutrient cycling and agrochemical degradation. ...
An analysis of northern hemisphere block sizes compared to climatology and seasonal variations
(University of Missouri--Columbia, 2012)
The goal of the following research was to discover if any trends exist between the size of large-scale, mid-latitude anticyclonic events and seasonal characteristics. A 20-year analysis of North American blocking events ...
The use of dispersion modeling to determine the feasibility of vegetative environmental buffers (VEBS) at controlling odor dispersion
(University of Missouri--Columbia, 2012)
Vegetative environmental buffers (VEBs) have been suggested as a possible odor control technology. They have been found to impact odor plume dispersion and have shown the possibility of being an effective tool for odor ...
Soil surface-seal measurement using high-resolution x-ray computed tomography (HRCT)
(University of Missouri--Columbia, 2006)
Rainfall on bare soil breaks soil aggregates, detaching particles, plugging pores and decreasing porosity in the top few mm of soil. This reduces hydraulic conductivity and increases runoff through a process known as surface ...
Elemental concentration changes in soil and stockpiled tall fescue leaves after liming
(University of Missouri--Columbia, 2006)
Tall fescue (Festuca arundinacea Schreb.) is the dominant forage in Missouri and grows primarily on acidic soils that possess little plant available phosphorus (P). Little is known about the effects of lime on the elemental ...
Use of slow-release N fertilizer to control nitrogen losses due to spatial and climatic differences in soil moisture conditions and drainage in claypan soils
(University of Missouri--Columbia, 2006)
Agricultural soils are a major source of nitrous oxide (N₂O) which has a significant environmental impact on global warming and ozone depletion. However, there is little information on soil N₂O emissions under different ...
A study of lightning flashes attending periods of banded heavy snowfall
(University of Missouri--Columbia, 2007)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT AUTHOR'S REQUEST.] Lighting[sic] flashes associated with 24 banded thundersnow events were analyzed to document their polarity, signal strength, and multiplicity. Radar ...
Variability of soil hydraulic properties and estimation of plant-available water on claypan-soil landscapes
(University of Missouri--Columbia, 2007)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] Soil hydraulic properties and plant-available water (PAW) capacity are critical properties in evaluating land management and soil productivity. This ...
Adsorption of isoxaflutole degradates to hydrous aluminum and iron oxides
(University of Missouri--Columbia, 2009)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] Isoxaflutole (IXF) is a pre-emergence herbicide that is rapidly transformed to a more stable and soluble diketonitrile degradate (DKN) after field ...
Risk and stability of phosphate-immobilized lead in contaminated urban soil and mining sites in the Jasper County Superfund Site
(University of Missouri--Columbia, 2007)
In situ application of soluble phosphates and organic matter is considered to be a cost effective remediation technique for immobilizing lead (Pb) and other heavy metals and reducing health and ecological risks associated ...
Polyacrylamide amendment for erosion and runoff control on soils of differing characteristics
(University of Missouri--Columbia, 2009)
The use of anionic polyacrylamide (PAM) as a soil amendment is an emerging conservation practice. However, guidelines have not been developed with considerations of soil properties and topographic characteristics. The ...
Impacts of soil management practices on soil fertility in potato-based cropping systems in the Bolivian Andean highlands
(University of Missouri--Columbia, 2010)
Due to changes in climate and socioeconomic developments, current soil management practices in the Bolivian Andean Highlands may be increasing soil degradation thereby threatening food security. A study was established in ...
Forest harvest effects on soil chemical properties and nutrient concentrations in Ozark Highland soils
(University of Missouri--Columbia, 2010)
Mixed hardwood systems of the Missouri Ozark Forest Ecosystem Project are harvested using clearcutting (CC) and single-tree selection (STS) regeneration methods. This work indicates possible effects of regeneration method ...
Classification of air pollution regimes in the Missouri region
(University of Missouri--Columbia, 2009)
