Hydrological and geomorphological significance of rock glaciers in the dry Andes, Chile (27°-33°S)
The latitudinal-altitudinal distribution of rock glaciers in the dry Chilean Andes between 27° and 33°S was analysed and their hydrological and geomorphological significance evaluated. Statistical estimation techniques were used based on digital

The article deals with the terms map use, thematic maps, cognitive theories and empiric studies. The student´s methodical knowledge of map use is decisive to communicate spatial information successfully within a school´s course of instruction. Some
The study was conducted at the Southern part of West Bank, near Hebron city, during 2005, 2006 and 2007. Five treatments were implemented; forests planted with P. halepensis (F), natural vegetation dominated by S. spinosum (W.S), natural vegetation
where S. spinosum was removed (W/o.S), cultivated land (C), and deforestation (Df). Three types of data were estimated in each plot: runoff after each rainfall event, sedimentation at the end of the rainy season, and chemical and physical soil properties
. The results indicate that forests and natural vegetation dominated by S. spinosum prevent or decrease the risk of runoff and soil erosion. In conclusion, the removal of S. spinosum and forest trees as a means to improve rangeland productivity increases runoff
