Pre-harvest water quality of ephemeral streams in Missouri Ozark forests
(University of Missouri--Columbia, 2006)
The Missouri Department of Conservation (MDC) developed a best management practice that leaves a riparian buffer next to streams to reduce the possibility of water quality degradation. The purpose of this study is to ...
Volume change and swelling pressure of expansive clay in the crystalline swelling regime
(University of Missouri--Columbia, 2008)
A significant amount of research has been carried out to characterize expansive clay behavior from either microstructural or macrostructural perspectives; however, there exists a current gap in our knowledge about the basic ...
Point target interferometry as applied to the characterization of localized deformation features
(University of Missouri--Columbia, 2008)
Monitoring of ground deformation is a critical component of geotechnical engineering practice. This study investigated the application of synthetic aperture radar interferometry (InSAR), using point target analysis (IPTA) ...
Development of shear wave velocity profiles in the deep sediments of the Mississippi Embayment using surface wave and spectral ratio methods
(University of Missouri--Columbia, 2008)
The deep soils of the Mississippi Embayment in the central United States will have a significant influence on earthquake ground motions generated by the New Madrid Seismic Zone. The seismic properties of these soils, which ...
Processing of synthetic aperture radar data as applied to the characterization of localized deformation features
(University of Missouri--Columbia, 2009)
Satellite-based Interferometric Synthetic Aperture Radar (InSAR) has been used by the geoscience community for many years to obtain ground deformation measurements of large-scale spatial features. Researchers have also ...
Characterization of disinfection by-product precursors from Missouri streams
(University of Missouri--Columbia, 2007)
The NOM contained in drinking water sources reacts with Cl2 to generate THMs and HAAs. THMs and HAAs are regulated by EPA because they pose a health hazard. The nature of the DBP precursors is complex and not well understood. ...
Geotextile separators for dust suppression on gravel roads
(University of Missouri--Columbia, 2006)
Dust can be a health concern because of its potential to contain respirable particles. The US EPA and state environmental agencies developed and implemented a reporting system for the amount of particulate (PM10) derived ...
Arsenic rejection by membrane processes : model development and application
(University of Missouri--Columbia, 2007)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] This study investigated the rejection of arsenic by several nanofiltration and inorganic clay membranes. Laboratory-scale experiments were conducted ...
Methodology for quantifying wetland landscape parameters for highway right of way decisions utilizing GIS
(University of Missouri--Columbia, 2008)
Wetlands are a type of habitat which forms an interface between aquatic and terrestrial ecosystems. A growing problem in the state of Missouri and around the nation is the loss of the natural wetlands due to the expansion ...
Development of solution techniques and design guidelines for equestrian trails on public lands
(University of Missouri--Columbia, 2007)
Increasing equestrian use on recreational trails puts intense pressure on the environment. Horse traffic produces high stresses that can cause trail degradation such as erosion and muddiness. Much is known about causes of ...
Development and application of vegetative buffer width modeling using geographic information systems
(University of Missouri--Columbia, 2009)
It has been widely accepted that vegetative buffers are effective in removing nonpoint source pollutants. However, problems focusing on vegetated buffers studies remain, especially in technical aspects (i.e., how to design ...
An evaluation of pre- and post-timber harvest water quality in low-order streams in the Missouri Ozarks
(University of Missouri--Columbia, 2009)
Missouri Department of Conservation's (MDC) best management practices (BMPs) for Regenerative Oak Clear Cutting (ROCC) practice was evaluated on effectiveness to preserve downstream water quality. Fifteen sites, located ...
Field performance of instrumentation for monitoring effects of timber harvesting on water quality
(University of Missouri--Columbia, 2006)
Water samples from ephemeral streams and associated hillsides are being collected to quantitatively determine the impact of Regenerative Oak Clear Cutting (ROCC) on water quality and sediment and nutrient transport in ...
Arsenic adsorption onto iron-chitosan composite from drinking water
(University of Missouri--Columbia, 2006)
To develop an inexpensive adsorbent, suitable for arsenic removal from drinking water, iron-chitosan based sorbents were selected. Chitosan is a biopolymer derived from chitin, a polysaccharide and is available commercially ...
Function-based condition indexing for guyed communication towers
(University of Missouri--Columbia, 2005)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT AUTHOR'S REQUEST.] Construction of the Missouri Department of Transportation (MoDOT) two-way radio network was initiated in the 1950's and was motivated primarily by the ...
Use of fluorescence excitation emission matrix spectroscopy for water and wastewater characterization
(University of Missouri--Columbia, 2006)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT AUTHOR'S REQUEST.] The Excitation Emission Matrix Spectroscopy (EEMS) has the potential to be used for the real time monitoring of environmental effects on water and ...
Occurrence and modeling of THMS and HAA formation in drinking water
(University of Missouri--Columbia, 2007)
, the formation of THMs and HAAs in drinking water plants in Missouri was investigated to further understand their occurrence and predict their formation. Firstly, the occurrence of TTHM and HAA5 in Missouri public water supplies was investigated by analyzing...
