Baseline Limnology And Nutrient Study Of Basin Head Lagoon, Prince Edward Island, With Management Implications, Karen Connolly
Baseline Limnology And Nutrient Study Of Basin Head Lagoon, Prince Edward Island, With Management Implications, Karen Connolly
Theses and Dissertations (Comprehensive)
Knowledge of physical and chemical process ongoing within an environment is an important step towards proper environmental management. Basin Head, Prince Edward Island is in the process of becoming a Marine Protected Area (MPA) and therefore a comprehensive management plan will need to be completed. The area contains a unique strain of Irish Moss (Chrondrus crispus Stackhouse) that is an important marine plant used in various industries. A study was conducted during the summer of 2000 to assess the basic physical and chemical conditions within the Basin Head Lagoon and surrounding stream inputs. The purpose of the study was to …
Dune Morphology Response To Water Level Change, Pinery Provincial Park, Ontario, Canada, Michael C.A. Bitton
Dune Morphology Response To Water Level Change, Pinery Provincial Park, Ontario, Canada, Michael C.A. Bitton
Theses and Dissertations (Comprehensive)
This thesis describes the geomorphological changes to a trough blowout in Pinery Provincial Park's sand dunes. The Park is located on Lake Huron’s southeastern shore where, due to rapid changes in Lake Huron water levels, a study could be completed examining the changes to blowout morphology based on the change in beach sediment supply. The study took place during relative low Lake Huron levels (1999-2000) and was compared to data collected during a period of relative high Lake Huron levels (1994-1995). Field research included erosion pin measurement to monitor and verify morphological change through the throat of the blowout, aeolian …
River Basin Ecosystem Restoration: A Comparison Of Conservation Authority Efforts (Ontario), Wilfred Gregory Tschirhart
River Basin Ecosystem Restoration: A Comparison Of Conservation Authority Efforts (Ontario), Wilfred Gregory Tschirhart
Theses and Dissertations (Comprehensive)
This thesis reviews a series of river basin ecosystem restoration/enhancement projects carried out under the direction of three individual southern Ontario conservation authorities in their respective river basins. The three authorities are the Grand River Conservation Authority, the Maitland Valley Conservation Authority, and the Upper Thames River Conservation Authority. A review from the published literature dealing with river basins, ecosystems, and environmental management supports the analysis of restoration projects. The criterion by which the literature articles were selected was that they have relevance to the type of environmental issues that are common to the river basins in the study areas. …
Structural And Sedimentary Characteristics Of The Tsergo Ri Rockslide Breccia, Langtang, Nepal, Himalaya, Mark B. Carpenter
Structural And Sedimentary Characteristics Of The Tsergo Ri Rockslide Breccia, Langtang, Nepal, Himalaya, Mark B. Carpenter
Theses and Dissertations (Comprehensive)
The high magnitude Tsergo Ri landslide (c. 100ka), Langtang Himal, with a volume in excess of 15km^3 and a vertical displacement of more than 1500m remains the largest crystalline rockslide in Nepal Himalaya. The Quaternary landslide affected rocks in gneissic fancies of the High Himalayan Crystalline Sequence adjacent to the Tibetan Sedimentary Series. Depositional characteristics from exhumed transport slope sites were analysed at both the macroscopic and the microscopic scale to investigate (i) localised fracture in terms of orientation and density, and (ii) petrography of slide induced host rock deformation. Fracture orientation analysis indicate the spatial orientation of preexisting discontinuities …
Ecosystem Health And Sustainable Livelihoods: Exploring The Prospects In Community-Based Resource Management In The East Mamprusi District, Ghana, Wuni P. Dasori
Theses and Dissertations (Comprehensive)
Institutional processes, social and economic trends play a role in defining the outcomes of people’s interaction with and use of their ecosystems. The resource use decisions of households influence the livelihood and health dimensions of ecological change. This thesis identifies community assets and activities, and examines how they both affect human and ecological health, productivity and community sustainability. It studies the relationship between changing biophysical conditions and community well-being in terms of health and livelihood by examining how agro-ecosystem based resource use systems influence community environmental change and vulnerability to health and livelihood problems inherent in their ecosystem. Three communities …
Seiche Events At The Slave River Delta And Great Slave Lake, Northwest Territories: An Assessment Of Process And Impact, James Tobias Gardner
Seiche Events At The Slave River Delta And Great Slave Lake, Northwest Territories: An Assessment Of Process And Impact, James Tobias Gardner
Theses and Dissertations (Comprehensive)
Seiche events are important hydrodynamic processes that impact the Slave River Delta, during the late summer and autumn. Given the scarcity of previous research on seiche events at river deltas and the physical dimensions and orientation of the Slave River Delta, this location at the southern shore of Great Slave Lake is ideal to study the occurrence and impacts of seiche events at a river delta. Seasonal changes to long-term water level trends and water level variability on Great Slave Lake, correspond to changes to the Slave River flow potentially associated with the impacts of regulation of the Peace River. …
Investigating Spatio-Temporal Variability Of Hydrological Components In The Canadian Rockies (Alberta), Christopher Dennis Hopkinson
Investigating Spatio-Temporal Variability Of Hydrological Components In The Canadian Rockies (Alberta), Christopher Dennis Hopkinson
Theses and Dissertations (Comprehensive)
This thesis addresses two questions related to the broad topic of mountain hydrology: 1) How do interannual hydrological balancee and pathway components vary in complex temperate high mountain environments at various spatio-temporal scales? 2) a) Is it possible, using dedicated hydrological models, for significant errors in simulated runoff components despite good hydrograph recreations (i.e. right results for wrong reasons)? b) If so, what kinds of errors are encountered? The first question was addressed by undertaking a hydrological tracer and hydrometric study at three basin scales (Banff —2200 km2, Lake Louise —400 km2 and the headwaters —30 km2) within the Bow …
