Oak Regeneration following Three Cutting Treatments on Mountain Slopes in Northern Alabama’
Early regeneration success of upland oaks (Quercus spp. L.) was compared for three regeneration cutting treatments in the Sandstone Mountain Region of northern Alabama. Two 4-acre replications each of block dearcutting. strip cutting, and deferment cutting were established on north-facing slopes. The three harvesting treatments were applied in midsummer. Regeneration subplots were reinventoried...
متن کاملTesting the daily PRISM air temperature model on semiarid mountain slopes
Studies in mountainous terrain related to ecology and hydrology often use interpolated climate products because of a lack of local observations. One data set frequently used to develop plot-to-watershed-scale climatologies is PRISM (Parameter-elevation Regression on Independent Slopes Model) temperature. Benefits of this approach include geographically weighted station observations and topograp...
متن کاملClimate and topography control the size and flux of sediment produced on steep mountain slopes.
Weathering on mountain slopes converts rock to sediment that erodes into channels and thus provides streams with tools for incision into bedrock. Both the size and flux of sediment from slopes can influence channel incision, making sediment production and erosion central to the interplay of climate and tectonics in landscape evolution. Although erosion rates are commonly measured using cosmogen...
متن کاملComparative Analysis on Soil Basic Properties Between Southern and Northern Slopes in Funiu Mountain, China
The spatial variation of soil physical and chemical properties in Funiu Mountain was studied to provide references for identifying soil spatial variation mechanism in bordering land of China warm temperate zone and northern subtropical region. Using vertical gradient sampling and traditional statistics method, the soil samples at the altitude from 1640 m to 1870 m were collected to compare phys...
متن کاملAntidunes on steep slopes
16 When increasing the rates of subcritical flow on gentle slopes, the bed successively produces 17 ripples, dunes and flat beds. Antidunes (defined here as all bed undulations for which the 18 surface gravity waves are in phase with the bed profile) appear only in high flow rates and 19 may be found in some extreme natural flow events. Inversely, on steep slopes flume 20 experiment (S≥1% appro...
