Download Environmental controls on geomorphic processes, Grizzly Creek, south-west Yukon Territory
Complicated by local spatial variability in forms, processes, and controls. However, due to thresholds, or to the presence of key environmental boundaries, distinct zones characterized by specific hydrological, ecological, and geomorphic characteristics can b e identified--though the boundaries between those zones may be gradual and indistinct.
Environmental controls on geomorphic processes, Grizzly Creek, South-West Yukon Territory / under the direction of P.G. Johnson. GB Y94 E58 Caribbean geography. (2) Examine longitudinal (downstream) changes in flow processes and energetics, channel and valley morphology, and patterns of recent geomorphic change.
(3) Classify the lower Sabine (based on items 1, 2) into geomorphic process zones. (4) Identify the primary controls—both contemporary and historic—of the geomorphic process zones. Some 20 electrical resistivity soundings were performed on rock glaciers in Grizzly Creek, south-west Yukon, to investigate the geometry of the permafrost and the amount of ice in the sediments.
Warming climate is causing substantial change in geomorphic process and OC ﬂuxes in high latitude rivers. We investigate geomorphic controls on ﬂoodplain soil OC concentrations in active-layer mineral sediment in the Yukon Flats, interior Alaska.
We characterize OC along the Yukon River and four tributaries in relation. Atlin Lake in northern British Columbia and southern Yukon Territory is the largest natural lake in the North American Cordillera ( km2).

The Environmental Systems concentration in Geography focuses on the processes that shape the physical features of the landscape. Climate, geology, and biology interact in complicated ways to result in the weather, landforms, and life that characterize any place.
In southern Arizona, a number of collaborations on environmental management and the promotion of ecosystem services, when taken together, can be treated as a polycentric system.
Alvarius In Cochise County, over 20 different groups and actors contribute to decision-making processes about pressing environmental challenges in the region. Data from table 1.

Given this geomorphic setting and the fact that virtually all the runoff is derived from high-elevation snowmelt, it is not surprising that such stream reaches.

On the Shelf. Environmental change in the Maritimes / edited by J.G. Ogden, M.J. Harvey. -- GB M2 E58 The relationship between settlement and the physical environment in part of the West Lake area of Manitoba from -- GB M3 C Observations indicate that over the past several decades, geomorphic processes in permafrost regions have been changing or intensifying (e.g., Rowland et al., ) indicating a system-wide response to changing climate (Hinzman et al., ).
The majority of geomorphic changes are related to permafrost warming, increased thickness of the active. The original Grizzly Creek diversion system consisted of a diversion structure approximately four miles above the confluence of Grizzly Creek and the Colorado River, about feet of inch diameter riveted steel pipe, and a 4½-foot diameter tunnel through solid rock to No Name Creek.

Historically, efforts to reduce flood damage in the Turkey Creek Basin focused on structural measures with minor consideration of environmental impacts from the proposed actions. While environmental impacts were to be minimized and offset, the primary objective was to reduce flood damage and associated economic losses.In Hawai‘i, between ~ and m are subalpine forests, woodlands, and shrublands.
