Skidding operations can cause considerable and wide spread soil disturbance. The objective of this study was to evaluate the effects of ground skidding operations on soil compaction, moisture content, and total porosity at different levels of slope and traffic frequency. Four levels of traffic intensity (3, 8, 13, and >13 passes of a Crawler Tractor Onezhets ? 110) and three levels of slope ( ...

Change detecting and timely updating of residential areas is widely recognized as one of the most challenging tasks for an operational GIS. High spatial resolution satellite data provide an efficient source of information. This paper describes a hierarchical object-oriented approach for extracting residential areas from IKONOS and SPOT5 images acquired in 2001 and 2004, respectively. Hierarchic...

The direction of development residential areas tends to be coastal which course will have impact on tsunami hazard. This study aims spatially model hazard and its exposure settlements City. research variables consisted land height, slope, distance from river, shoreline. uses overlay technique been assess...

Along various stretches of the Antarctic margins, dense Antarctic Bottom Water (AABW) escapes its formation sites and descends the continental slope. This export necessarily raises the isopycnals associated with lighter density classes over the continental slope, resulting in density surfaces that connect the near-freezing waters of the continental shelf to the much warmer CDW at mid-depth offs...
