The surface mining of coal has accelerated in
northwest Colorado to the point where public pressure
plus impending state and federal regulations dictate the
need for comprehensive reclamation plans. A large coal
company operating in Moffat County has solicited recommendations
concerning soils, hydrogeology, geomorphology,
aesthetics, wildlife, vegetation, microclimatology, and
legal...
Based on a pilot study completed near Heceta
Beach, Oregon, guidelines have been proposed for
the development of Oregon coastal sand areas.
The guidelines, in the form of performance standards
are designed with respect to the variability of
coastal sand areas. Landscape units and vegetation
associations were grouped to reflect...
Lincoln City, Oregon is an area of active environmental
processes and increasing development. To reduce conflict, a larger
data base on environmental hazards was required. Previous studies
in the area, remote sensing techniques and. field research were used
to accomplish this end. Within Lincoln City, numerous environmental
hazards were identified...
In attempting to provide modern water and
sewerage services to the non-indigenous inhabitants of
Canadian Arctic communities, engineering modifications are
necessary owing to the presence of a continuous permafrost
zone and a severe climate. Modifications are constraints
on communities in that the costs of providing water and
sewerage services are...
Stream channel stability for two tributaries of Rock Creek in the
Oregon Coast Range is evaluated by application of a Stream Reach Inventory.
Stability nomographs are constructed for graphical analysis of
erosion potential. Results indicate that channel stability can be
classified. One stream is rated as 'Poor' in resistance to...
Sections of the landscape in north central Oregon are
dominated by numerous soil mounds surrounded by stone rings. Mounds
vary in size and shape depending on slope and mound density. Internal
soil mass is free of stones to the bedrock level and is covered
by successive layers of volcanic ash....
In order for proper land use planning
to occur in coastal Lincoln County, Oregon, coastal
erosion rates should be determined. This has been
accomplished by identifying the location of the
Lincoln County coast in 1939, 1959, and 1973 and
measuring the amount of change occurring between
the years. The area...
A study conducted along the Lincoln County, Oregon coast
delineated the exact location of 153 landslides. The landslides were
found through the interpretation of aerial photographs. Each landslide
was verified in the field and its class (ancient, historic, recent),
type (slump, debris slide or flow, planar slide), and status (stable,...
If wind power is to become a viable energy alternative, a rapid and reliable cost effective methodology must be established, whereby large areas can be surveyed for windy sites and those sites can be evaluated. Based primarily on locating wind deformed vegetation, this paper establishes the feasibility of using air...
The ocean wave conditions at the mouth of the Columbia River have
long proven a hazard to ship navigation. Over 62 major shipwrecks
have occurred at, or in the vicinity of the river entrance. The wave
pattern is extremely complex, varying seasonally with prevailing winds
and river discharge, as well...
