Gully in arid climate.

In arid climates, where water is scarce, it is crucial to choose crops that can maximize their water-use efficiency. Choosing crops with high water-use efficiency is significant for water-wise farming in arid regions. These crops can produce more biomass or yield per unit of water consumed, ensuring optimal use of limited water resources. ...The resulting high-resolution images (pixel sizes > 10 cm) are employed for photogrammetric and GIS analysis in order to quantify gully development with linear, areal and volumetric measurements at various sites in semi-arid landscapes of Spain and Africa.Linear headcut retreat rates for 12 gullies were analysed in order to investigate their ...Oct 31, 2005 · At each gully head, one or several headcuts, 1.5 to 4.5 m high, are incised into the valley floor, exposing the alluvium sequence down to a coarse conglomerate or to the bedrock. The gully heads divide the valleys in the region into two main segments: (a) The upper valley upstream of the gully head up to the headwater of the drainage basin. In ... gully expansion and rehabilitation have been more extensively researched in the semi-arid region of Ethiopia, few studies have been conducted in the (sub) humid region. For that reason, we assessed the severity of gully erosion by measuring the expansion of 13 selected permanent gullies in the sub-humidAlong with the global climate change, gully erosion, flood and drought jointly restrict the sustainable development of arid rangeland in Central Asia.
