the problems of land degradation and soil loss are among the major problems of watersheds in iran. for erosion andsediment estimation one can use statistical and empirical methods. for doing this, land unit map and the map of effectivefactors should be prepared. for erosion and sediment estimation one can use statistical and empirical methods. however,these empirical methods are usually time co...

Background & Aims of the Study: Water resources are useful or potentially useful. Uses of water are included agricultural, industrial, household, recreational and environmental activities. The majority of human uses require fresh water. Rivers are parts of this fresh water that play a very important role in the water cycle, acting as drainage channels for surface water. Hence, ...

or as the ends of a boiv are drawn together." They have a legend that it visits the country every thirty years. The epidemic arrived in Bhamo in June last, having travelled up the Irrawaddy Yalley starting in Rangoon in May and visiting Mandalay during the early part of June. It is interesting to note this following of the important trade route. It is not unlikely that the epidemic originated f...

Age and growth of Mesopotamian barb, Capoeta damascina, were studied in the Zayandehrud River, in central Iran, from March 2007 to April 2008. Among the 689 specimens studied, age groups in males ranged from 1+ to 9+ and that in females ranged from 1+ to 10+. The sex ratio (1M:1.6F) was not significantly different from 1:1 ratio. Maximum fork length and weight was 39 cm and 1,115 g for males an...

Precise knowledge of crop water consumption is essential to better manage agricultural use, particularly in regions where most countries struggle with increasing and food insecurity. Approaches such as cloud computing remote sensing (RS) have facilitated access, process, visualization big geospatial data map monitor requirements. To find the reliable Vegetation Index (VI)-based evapotranspirati...
