Watershed analyses of nutrient removal in riparian buffers have been limited by the geographic methods used to map buffers and by the statistical models used to test and quantify buffer effects on stream nutrient levels. We combined geographic methods that account for buffer prevalence along flow paths connecting croplands to streams with improved statistical models to test for buffer effects o...

Streambed aggradation and degradation are ways in which a stream will respond to changes the incoming flow sediment loads. Several environmental societal problems attributed these channel bed adjustments. Prior studies have extensively used power discern dominant processes establish threshold limits required trigger modifications. However, were constrained by limited datasets scope of applicati...

Determining site quality is essential in order to develop sustainable forest management, allowing more appropriate silvicultural decisions be made. However, most studies carried out Spain have focused on a few species and at local scale, which makes it difficult apply the findings or conduct larger scales. The aim of this study obtain map national scale for main (Pinus sylvestris, Pinus uncinat...

The Cainozoic history of the Malanna area included faulting, deposition of sediments by streams or in lakes and swamps, two epochs of planation, and stream erosion. There is no physiographic, depositional or structural evidence for gladation in this area, the type area of Lewis's Malanna Phase of the Pleistocene glaciation. This phase must be considered invalid on the eviaence available in the ...

The spatial variabi]Lity and co-variability of two different types of remote sensing derivatives that portray vegetation and geomorphic patterns are analyzed in the context of estimating regional-scale CO 2 flux from land surfaces in the arctic tundra. For a study area encompassing the Kuparuk River watershed of the North Slope of Alaska, we compare satellite-derived maps of the normalized diff...
