We studied young riparian cottonwoods (Populus spp.) and associated woody plants along Soda Butte Creek and the Lamar River in northeastern Yellowstone National Park (YNP) to examine the potential influence of wolf/elk interactions upon plant growth. After a period of approximately 70 years without wolves in YNP, they were reintroduced in the winter of 1995–1996. When we compared woody plant he...

Abstract. Gully erosion can be a major disruptor to global fluvial sediment budgets. in the catchments of Great Barrier Reef is attributed ?40 % fine suspended pollution freshwater and marine ecosystems downstream. Mitigating this source will have lasting positive impact on water quality connected rivers receiving environment. Here we conduct preliminary evaluation ability intensive landscape-s...

Introduction: The discovery of gullies on Mars attracted significant attention because of the apparent role of liquid water in their formation and because of their very youthful nature [1,2]. They were initially interpreted to be the result of groundwater discharge [1-3], though further considerations regarding the current metastability of liquid water on the surface of Mars generated alternati...

The Covurlui Plateau, a subunit of the Moldavian Plateau located in eastern Romania, possesses high natural agricultural potential, significantly impacted by soil erosion, particularly gully erosion. only inventory that comprises approximately 9000 gullies extracted from topographical maps was conducted during 90s. Nowadays, with advent advanced techniques and geodata, such as GIS software, aer...

Gully erosion represents one of the most destructive geomorphological processes at a global level. Modern methods gully measurement are typically derived from earlier techniques that have since become outdated. The increasing capabilities technology had led to new ways quantifying soil (e.g. erosion) which must be used in assessment. A tool designed assess coastal – Digital Shoreline Analysis S...

Purpose: to determine patterns of formation hydrographic network elements depending on the melt-and rainwater runoff and soil losses. Materials methods. The studies were carried out in upper reaches Bolshoy Log gully system, which is a part land use experimental farm “Polevoy” Federal Rostov Agrarian Research Center, with an area 2070 hectares, more than 70 % arable land. Soils are ordinary che...

I present lunar landslides that bear a striking resemblance to some martian gullies, despite the lack of water on the Moon both today and in the past. This observation indicates that gully features can be formed via a dry landslide mechanism. Thus on Mars, morphology alone is insufficient to determine the mechanism of formation of these features. Introduction: In 2000, Malin and Edgett (1) repo...
