Abstract Introduction Successful restoration of terrestrial drylands depends on stable, fertile soils that retain water. These functions are provided by biological soil crusts (biocrust), suggesting their reestablishment is a critical step in dryland restoration.

Downcurrent variation in submarine channel‐fill architecture from the shelf to upper slope
ABSTRACT The transition between the shelf and the upper slope is often considered an area of sediment bypass, where steeper gradients increase flow velocities and maintain particles in suspension. In addition to transferring sediments into deeper basins, upper‐slope areas can also host channelised submarine deposits.

Towards an Assessment of the Ephemeral Gully Erosion Potential in Greece Using Google Earth
Gully erosion may cause considerable soil losses and produce large volumes of sediment. The aim of this study was to perform a preliminary assessment on the presence of ephemeral gullies in Greece by sampling representative cultivated fields in 100 sites

ABSTRACT Alpine, subalpine and montane peatlands provide important ecosystem services, including carbon storage, water regulation and habitat provision, and are threatened by a range of disturbance and degradation processes that impact these services.

Experimental Study on Influencing Factors of Ephemeral Gully Erosion on Losses Slope
Ephemeral gully erosion is an important erosion type in hilly area of Loess Plateau.The influence of rainfall intensity,area of upper catchment,gradient and tillage to ephemeral gully was studied preliminarily by simulating experiments.Main conclusions ...

Deriving Ephemeral Gullies from VHR Image in Loess Hilly Areas through Directional Edge Detection
Monitoring ephemeral gullies facilitates water planning and soil conservation. Artificial interpretation based on high spatial resolution images is the main method for monitoring ephemeral gullies in large areas; however, this method is time consuming ...

MONITORING AND ESTIMATION OF SOIL LOSSES FROM EPHEMERAL GULLY EROSION IN MEDITERRANEAN REGION USING LOW ALTITUDE UNMANNED AERIAL VEHICLES [PDF]
Calculation of gullies by remote sensing images obtained from satellite or aerial platforms is often not possible because gullies in agricultural fields, defined as the temporary gullies are filled in a very short time with tillage operations. Therefore,

Selected Physical and Geotechnical Properties of Loess in Wairarapa Valley, New Zealand
Loess up to 10 m thick covers marine terraces, old river aggradation terraces, and gentle hill country slopes in Wairarapa, New Zealand. In the drier eastern and southern parts of Wairarapa, the loess is subject to dry summer and autumn and wet winter and spring in most years.
