Soil-landscape relationships at the lower reaches of a watershed at Bear Creek near Oak Ridge, Tennessee
This study examines the effects of slope and geomorphic processes, human impacts, and particular characteristics of soils and saprolite that may effect drainage and water movement in the wetlands and adjacent landscapes in a watershed at Bear Creek

The objective of this paper is to investigate whether the systematic variations of bedload grain-size distributions observed in OakCreek can serve as the basis for calculations of transport rates of different size fractions. The approach will rely
of cosmogenic radionuclide surface exposure ages, uranium series and soil-development formation times. The AA. also determine incision rates of 2 tributaries to the Colorado River : OakCreek and Bridge Creek.
Erosion rates over millennial and decadal timescales at Caspar Creek and Redwood Creek, Northern California Coast Ranges
Detailed measurements of sediment fluxes in the Northern California Coast ranges at Caspar Creek and Redwood Creek have provided estimates of physical erosion rates since 1963 and 1971, respectively. They used cosmogenic Be 10 to measure millennial
-scale denudation rates averaged over 1400-8700 years at 6 catchments in Caspar Creek and 4 catchments in Redwood Creek. These measurements suggest that denudation rates at Caspar Creek are slower than rock uplift rates, implying that Caspar Creek
The AA. use dendrochronology to identify establishment dates for stems of major riparian tree species in the Sespe Creek watershed, in order to examine their relationship to regional flooding and fire history. The 11 study sites were burned by major
development are highlighted : 1) alder, cottonwood and oak soon after the 1932 Matilija Fire; 2) minimal stem establishment between the 1940s and mid-1960s, and 3) continued, although irregular, recruitment of alder and cottonwood since the late 1960s
the transport capacity formulations developed for steady flows (OakCreek, Oregon State, USA) can be applied even under unsteady flows such as flash floods. Complementing the time scale analysis, a series of computational exercises using a coupled shallow water
Creek morphology in the Sceldtpolders near Zelzate
Several creeks with different morphological and landscape characteristics occur in the Sceldtpolders area near the polderlimit between Zelzate and Aardenburg. In this paper diverse fossil creektypes, creeksediments and creekpatterns are discussed
. An orthogonal creek pattern can be reconstructed by detailed geomorphological mapping. The relation is examined between this exceptional creekpattern and the underlying fossil parcelpattern.
Late Quaternary alluvial history of Nowlands Creek, Hunter Valley, NSW
The purpose of this paper is to unravel the alluvial history of Nowlands Creek at the archaeological sites. In particular, the river terraces and their stratigraphy, soils and chronology will be evaluated to separate Pleistocene from Holocene

Glaciotectonism and landsliding in Little Sandhill Creek, Alberta
This paper deals with a landslide on the north side of Little Sandhill Creek (Dinosaur Provincial Park). The slide was studied intensively because it contained several large stratigraphic exposures which provided clear indications of the effects

The establishment and degeneration of a temporary creek system in response to managed coastal realignment : The Wash, UK
This paper examines the growth and decay of an ephemeral creek system produced in response to a managed realignment at Freiston Shore, The Wash. In addition, the natural and anthropogenically enhanced developments of the creek system are compared.
A rock glacier/debris-covered glacier system at Galena Creek, Absaroka Mountains, Wyoming
At Galena Creek, the ice/debris system has alternated between rock glacier and debris-covered glacier modes due to changes in the size of the accumulation area. These results have important implications for paleoclimatic studies of the ice
Waterhole form and process in the anastomosing channel system of Cooper Creek, Australia
One of the most distinctive features of Cooper Creek's anastomosing channel system is the preponderance of waterholes, enlarged segments of channel ranging in length from 100 m to over 20 km. They play a significant hydrological and geomorphological
role in the Cooper Creek anastomosing system. They provide long-term water storage in an arid environment, and their fixed position helps to maintain the stability of the multi-channel pattern.
The Sisters Creek Formation: Pleistocene sediments representing a nonglacial interval in southwestern British Columbia at about 18 ka

Historical channel-bed elevation change as a result of multiple disturbances, Soldier Creek, Kansas
This paper presents the results of a U.S. Geological Survey study to determine and explain the spatial and temporal dimensions of channel change along Soldier Creek, a stream affected by multiple disturbances in northeast Kansas. In this study
, channel-bed elevation was used as the primary indicator variable to determine the location, type, magnitude, timing, duration, trend, and rate of change throughout the Soldier Creek system.
