Nutrient Transport And Storage In A Karst Spring-Reservoir System During Baseflow, Missouri Ozarks, Heather A. Moule
Nutrient Transport And Storage In A Karst Spring-Reservoir System During Baseflow, Missouri Ozarks, Heather A. Moule
MSU Graduate Theses
Urban and agricultural land uses are important sources of nitrogen and phosphorus which, if in excess, can cause eutrophication in lakes and rivers. There have been few studies of nutrient transport and storage in karst spring and reservoir connected stream systems draining the Missouri Ozarks. This study aims to link the baseflow nutrient contributions of Sanders Spring to downstream reservoir outflow and the Headwaters South Dry Sac River Watershed in Springfield, Missouri. Water samples were collected seasonally and analyzed for total nitrogen (TN), total phosphorus (TP), and several other water quality parameters. Discharge was also monitored to calculate water and …
Nutrient Concentrations At Baseflow Conditions In The Upper White River Basin, Southwest Missouri And Northwest Arkansas, Gopala G. Borchelt
Nutrient Concentrations At Baseflow Conditions In The Upper White River Basin, Southwest Missouri And Northwest Arkansas, Gopala G. Borchelt
MSU Graduate Theses
The Upper White River Basin (UWRB) is becoming increasingly vulnerable to water quality degradation from urban/population growth and increased agricultural production. This study examines the relationships among nutrient levels, water chemistry and watershed characteristics of 19 watersheds in the UWRB. Water samples were collected during baseflow conditions each month for one year at USGS continuous-flow gage stations. Watershed characteristics evaluated were land use, geology, drainage area, flow discharge, and wastewater treatment plant discharge (WTP). Measured chemical water quality indicators include total nitrogen (TN), total phosphorus (TP), specific conductivity, turbidity, pH and dissolved oxygen. Rapidly expanding urban areas are associated with …
Nutrient Loads In An Urban Ozark Watershed: Jordan, Fassnight And Upper Wilson's Creeks, Springfield, Missouri, Ronald B. Miller
Nutrient Loads In An Urban Ozark Watershed: Jordan, Fassnight And Upper Wilson's Creeks, Springfield, Missouri, Ronald B. Miller
MSU Graduate Theses
The study watershed includes Jordan Creek, the primary stream draining the central downtown area of Springfield, Missouri, and also Fassnight and upper Wilson Creeks. Ten sample sites were established within the watershed and water samples and were collected during baseflow and storm runoff events between August 1, 2004 and July 31, 2005. Samples were tested for total nitrogen (TN), total phosphorus (TP) and selected heavy metals (zinc, arsenic, lead, copper and cadmium) and the parameters pH, specific conductance, turbidity, temperature and dissolved oxygen. Rating curves were used to correlate discharge and water quality variables. Separate rating curves were developed for …
