salzmannii burned in 1998 to gain further understanding of the relative importance of different factors related to local topography (elevation, aspect, slope, curvature), pre-fire vegetation (land-use history, canopy cover) and fire behavior (burn severity, presence of unburned patches) as drivers of post-fire regeneration dynamics.
We describe and then model satellite-inferred severe (stand-replacing) fire occurrence relative to topography (elevation, aspect, slope, solar radiation, Heat Load Index, wetness and measures of topographic ruggedness) using data from 114 fires > 40 ha in area that occurred between 1984 and 2004 in the Gila Wilderness and surrounding Gila National Forest.
The main goal of this study was to examine the influence of topography (slope aspect, percent slope, and slope position as calculated from a landform index (LI)) and plot characteristics (tree height, age, and canopy cover) on the distribution of trees (diameter at breast height, dbh≥10 cm), saplings (dbh<10 cm), and CWD in a mixed-oak forest of unglaciated southern Ohio (USA).
One approach to meet multiple management objectives is to build on previous spatial delineations of forested landscapes generated for singular purposes, and create units harboring different stand structures and fuel loads driven by changes in topography and aspect.
As such, I related the occurrence data to a suite of environmental data including dimensions of climate (annual mean temperature, mean monthly maximum temperature, mean monthly minimum temperature, annual precipitation; from [ 32]) and topography (slope, aspect, compound topographic index; from [ 33]).
At very large spatial scales, the impacts of topography, elevation, and aspect on throughfall variability are apparent.
Finally, similarly to the concluding step of the grassland productivity evaluation, correction coefficients were applied to evaluate the effect of the topography (slope and aspect) on the productivity of cropland soils.
This example was selected to emphasize the importance placed on landform, topography, slope gradient, aspect, and slope position as key criteria for differentiating the lower level units in the system.
Further studies might be required to fully understand and clarify the influence of aspect, topography and vegetation types on soil properties for site-specific soil resource management practices in this mountainous area.
To help design wind turbines around numerous high-rise buildings with promising wind in Hong Kong, this paper presents an integrated method of both macro (weather data and domain topography) and micro aspect (Computational Fluid Dynamics, CFD) analysis.
