Our main goal is to assess the hydrodynamics of turbidity currents and mudflows and their ability to produce morphological features such as ripples, dunes, antidunes and gullies along their paths. Of particular interest is to elucidate the role played by turbidity currents on the inception of submarine channels and canyons. To this end, understanding the mechanics of sediment erosion, including...

background & aim: st john's wort (hypericum perforatum l.) contains hypericin and hyperforin as the main components of the extract that binds with gaba and sigma opioid receptors. this herb has many pharmacological effects, including analgesic, sedative, soothing, antispasmodic, anticonvulsant, anti-depressant, and anti-bacteria. in this study examined the effect of two concentrations of hy...

Although huge numbers of gullies have been widely formed and severely decreased the quality farmlands in mollisols, it is still unclear how microbial community distributes after natural vegetation restoration (NVR), which highly relates to ecological functions farmland. In this study, both their potential NVR were reviewed, together with environmental factors relating evolution detected two mol...

Geo-hydrological phenomena, including gullies, contribute significantly to soil erosion and land degradation. To address this, proper management of basins hillslopes should consider the mechanism, timing, location gully development how gullies interact with other hillslope processes. Yet, conventional modelling techniques for such processes are rare, frequently being limited applications only s...

Considering the linear erosion processes in river basins slopes it can be noticed that gully is most intensively changing relief, leading to complete soil cover destruction, and making land not suitable for agricultural use. The latest maps of gullies'development Russia were compiled more than 50 years ago seen as very outdated. Since time no comprehensive gullies network mapping has been carri...
