Topography may mitigate drought effects on vegetation along a hillslope gradient
Ecohydrology 2017;e1825. https://doi.org/10.1002/eco.1825 Abstract Topography may mitigate drought effects on vegetation along a hillslope gradient through redistribution of soil moisture. We examined the interaction of topography, climate, soil moisture, and transpiration in a low‐elevation, mixed‐hardwood forest in the southern Appalachian Mountains. The effects of meteorological variation (w...
متن کاملTundra Fire and Vegetation Change along a Hillslope on the Seward Peninsula, Alaska, U.S.A
A 1977 tundra fire burned a hillslope where prefire soils and vegetation ranged from poorly drained moist tussock-shrub tundra on the lower slopes to well-drained dwarf shrub tundra on the back slope and very poorly drained wet sedge meadow on the flat crest. We sampled the vegetation on this slope before the fire and at 8 sites following the fire at irregular intervals from 1 yr to 25 yr. Duri...
متن کاملComment on “ Hillslope Topography From Unconstrained Photographs
A paper recently published in Mathematical Geology raises some concerns, which need to be expressed. The paper is entitled “Hillslope topography from unconstrained photographs” by Heimsath and Farid (2002) and presents a “simple methodology to extract the high resolution 3-dimensional topographic surface from photographs taken with a hand-held camera with no constraints imposed on the camera po...

متن کاملHillslope Topography From Unconstrained Photographs1
Quantifications of Earth surface topography are essential for modeling the connections between physical and chemical processes of erosion and the shape of the landscape. Enormous investments are made in developing and testing process-based landscape evolution models. These models may never be applied to real topography because of the difficulties in obtaining high-resolution (1–2 m) topographic...
