Estimating above and below ground vegetation biomass and carbon storage across an intra-urban land-use gradient in mid-Missouri
(University of Missouri--Columbia, 2015)*Urbanization includes a gradient of disturbance along which impacts on vegetative communities can widely vary. Urban forests play a vital role as carbon sinks for atmospheric carbon dioxide. In order to further understanding ... -
The horizontal redistribution of anomalous vertical heat fluxes at tropical latitudes /
(University of Missouri--Columbia, 2017)A study was conducted to improve quantitative understanding of how anomalous vertical heat fluxes associated with the El Nio-Southern Oscillation (ENSO) are transported poleward to maintain climate equilibrium. State-of-the-art ... -
An integrated modeling approach for estimating the potential hydrologic impacts of urbanization and climatic changes in Hinkson Creek watershed
(University of Missouri--Columbia, 2016)Land-use changes and climatic changes are two of the most significant phenomena impacting water regimes globally. Since ongoing land-use changes in the form urbanization and projected climate changes are expected to have ... -
Investigating soil carbon, nitrogen and respiration across an intra-urban gradient in mid-Missouri
(University of Missouri--Columbia, 2015)Carbon (C) storage by urban soils is an attractive option to reduce atmospheric CO2. However, C dynamics are complicated by the gradient of land use and vegetation assemblages associated with urban development. Soil total ... -
The Land Capability Potential Index: a decision support tool for the management of Missouri River floodplain habitat
(University of Missouri--Columbia, 2015)The Land Capability Potential Index (LCPI) is a hydrogeomorphic model of potential flow-return interval and soil drainage developed as a decision support tool for the restoration and management of floodplain habitat on the ... -
The long-term impacts of forest removal on floodplain subsurface hydrology
(University of Missouri--Columbia, 2015)A study was implemented in fall 2010, in the Hinkson Creek Watershed, Missouri, USA to improve quantitative understanding of the long-term impact of forest removal on floodplain hydrology. Automated volumetric water content ... -
Macroinvertebrate assemblage composition along a longitudinal multiple-land-use gradient in a midwestern stream
(University of Missouri--Columbia, 2012)Land use changes often alter hydrogeomorphology and hydrologic flow regimes, which can adversely impact stream aquatic biota. Hinkson Creek Watershed (HCW, 231km2) located in Boone County, central Missouri, is comprised ... -
Measuring and modeling stream and air temperature relationships in a multiland use watershed of the central United States
(University of Missouri--Columbia, 2014)A nested-scale experimental watershed study design approach was used in an urban watershed of the central U.S. to investigate stream water temperature (Tw) variability during water year's 2011, 2012, and 2013. Drought ... -
Measuring and modeling suspended sediment and nutrient yields in a mixed-land use watershed of the central United States
(University of Missouri--Columbia, 2016)Science-based information is needed to better understand mixed-land-use contributions of suspended sediment and nutrient loads to receiving water bodies. Water samples were analyzed for suspended sediments and nutrients ... -
Measuring and modeling water and nutrient flux between a mid-Missouri stream and forested riparian zone in the central U.S.
(University of Missouri--Columbia, 2012)To improve process based understanding of stream water-groundwater interactions, high-frequency water quantity data were collected from four stilling wells and two transects of piezometers (n = 6 each) during the 2011 water ... -
A multi-configuration evaluation of the soil and water assessment tool (SWAT) in a mixed land use watershed in the central U.S.A.
(University of Missouri--Columbia, 2011)Distributed watershed hydrologic/water quality (H/WQ) models are ubiquitous tools for watershed management. Despite advancements, there remain impediments for end-users. This study presents a practical framework for use ... -
Quantifying bottomland hardwood forest and agricultural grassland evapotranspiration in floodplain reaches of a mid Missouri stream
(University of Missouri--Columbia, 2013)Bottomland hardwood forests (BHF) play an important role in floodplain dynamics, particularly along urban streams where flood mitigation is critical to protecting human life and property. Enhanced evapotranspiration (ET) ... -
Quantifying microclimate heterogeneity within a contemporary plant growth facility
(University of Missouri--Columbia, 2013)Three separate contemporary climate controlled greenhouse rooms in the Sears Plant Growth Facility located at the University of Missouri, Columbia, MO, USA were selected for microclimate analysis. Temperature, relative ... -
Quantifying riparian canopy energy attenuation and stream temperature using an energy balance approach
(University of Missouri--Columbia, 2011)Forested riparian buffers play an important role in modulating stream water quality, including temperature. Few studies have quantified the relationship between stream temperature and canopy cover in the climatologically ... -
Quantifying stream bank erosion and deposition rates in a central U.S. urban watershed
(University of Missouri--Columbia, 2012)Stream bank stability is gaining increasing attention in part because stream bank erosion can contribute as much as 80% of suspended sediment to streams, particularly in urbanizing watersheds. Stream bank erosion study ... -
Quantifying suspended sediment loading in a mid-Missouri urban watershed using laser particle diffraction
(University of Missouri--Columbia, 2011)Midwestern streams and rivers of the United States are known for high suspended sediment concentrations (SSC), which is also one of the leading sources of water impairment. Unfortunately, there is a lack of understanding ... -
Quantifying urban stormwater suspended sediment particle size class distribution in the central U.S.
(University of Missouri--Columbia, 2013)Stormwater samples were analyzed from 17 urban monitoring sites (n=272) during spring 2011 to better understand urban land use suspended sediment contributions to receiving water bodies in central Missouri, USA. Samples ... -
A stream physical habitat assessment in an urbanizing watershed of the Central U.S.A.
(University of Missouri--Columbia, 2015)Longitudinal variations in aquatic biological habitat in a watershed (frequently associated with land-use in mixed-land-use watersheds) can be quantified by means of a physical habitat assessment (PHA). PHA indices include ...
