A Study Of Ground-Water Quality In A Priority Agricultural And Livestock Watershed, Cass County, Michigan, Matthew Alan Stuk

Masters Theses

A study of ground-water contamination in a shallow, sandy, glacial drift aquifer was performed in a watershed dominated by swine feedlots and crop fields in Cass County, Michigan. Monitoring wells were installed and sampled to study the flow pattern, chemistry, and contamination of ground water.

Results of chemical analyses show contamination from fertilizers and other soil-applied chemicals as well as the infiltration of breakdown products from pig waste. Shallow wells in impacted areas show potassium and nitrate from the breakdown of fertilizers, calcium from field application of lime, and additional nitrate from pig waste. Elevated calcium, potassium, and nitrate concentrations …

Hydrogeologic Characterization Of A Multi-Aquifer System At Station 11 In Kalamazoo, Michigan, Linda G. Jones

Masters Theses

The purpose of this study was to determine the hydraulic connection between the upper and lower confined glacial drift aquifers. The results of this study are based primarily upon the geologic profiles, a comparison of the head differences within each aquifer, potentiometric surfaces and different lag times for precipitation to reach each aquifer.

Results of the aquifer test showed that the upper confining layer pinches out in the western part of the well field. This area also provided significant recharge to the well field during the aquifer test. Data collected during the aquifer test and the increases in water levels …

Investigation Of Hydrometeorological Relationships, Pasu Glacier Basin, Northern Pakistan, Bob Boyce

Theses and Dissertations (Comprehensive)

Records of air temperature, global radiation and discharge from the Pasu Glacier basin in the Upper Indus River Basin have been examined with a view to developing a modest understanding of the simple physically based processes in action within this globally extreme mountainous region. Some glaciological data are also reported but in a preliminary manner. Relationships between air temperature characteristics, global radiation and discharge were investigated using correlation techniques. Daily average air temperatures recorded at the highest meteorological station, Parundas (4200m), provide the strongest degree of association with discharge. The data shows that this highly glacierised Karakoram basin exhibits similar …

River Channel Stability And The Implications For Fish Habitat, John T. Beebe

Theses and Dissertations (Comprehensive)

The purpose of this project was to investigate various aspects of river channel stability as they relate to fish habitat. Two headwater creeks of the Credit River system, Black and Silver Creeks, and their confluent stream, the West Credit River in Southern Ontario were used in the study. Thirty-five cross-sections were established and revisited during four flow regimes, summer base flow, fall secondary peak flow, spring melt-high flow and post-spring high flow. Measurements of width, depth and temperature were taken at these times. Water samples were taken for determination of suspended sediment concentration. Channel stability was investigated in relation to …

Hydrologic Investigations Of Meltwaters Draining Gornergletscher And Findelengletscher, Switzerland Using Hydrochemistry And Isotopic Analyses, Robert A. Metcalfe

Theses and Dissertations (Comprehensive)

The purpose of this thesis is to investigate the hydrological dynamics of Gornerglestcher and Findelengletscher, Switzerland by performing hydrochemical analyses on the bulk runoff exiting the portal of these two alpine glaciers. The hydrochemical analyses utilized electrical conductivity, as a surrogate for total dissolved solids, to determine the flow of routing of the bulk runoff (englacial or subglacial as defined by Collins, 1979b) and 8^18O to determine the contributions of pre-event and event water to bulk runoff during precipitation events. The pre-event water was defined as a combination of snow meltwater, ice meltwater and groundwater as these flow components could …

The Role Of The Vadose Zone In The Generation Of Runoff From A Headwater Basin In The Canadian Shield, Robert Alex Maclean

Theses and Dissertations (Comprehensive)

Hydrological processes occurring within the vadose zone, especially in heterogeneous soils and tills typical of the Canadian shield, are not well understood. This research investigates the importance of the vadose zone in a small headwater basin (Harp 4-21) in the Canadian shield with respect to the generation of stream runoff quantity and quality during episodic rainfall and snowmelt events. The study focused specifically on: firstly the effect of variable antecedent moisture conditions on water-table and stream response, secondly, the significance of the stored vadose water in water extracted from a rising water-table, and thirdly the significance of preferential flowpathways in …
