The interbasin water transfer project is an alternative to balance the nonuniform temporal and spatial distribution of water resources and water demands, especially in arid and semi arid regions. A water transfer project can be executed if it is environmentally and economically justified. In this study, the feasibility of two interbasin water transfer projects from Karoon River in the western p...

Understanding the constraints on light-use efficiency (LUE) induced by high evaporative water demand (vapour–pressure deficit; VPD) and soil stress (soil moisture content; SMC) is crucial for understanding simulating vegetation productivity, particularly in arid semi-arid regions. However, relative impacts of VPD SMC LUE are unclear, as we lack a mechanistic their interactions. In this study, q...

an agroecological zones (aez) map is an essential tool for agricultural planning. by integrating the key components of the agricultural environments, it offers a bird's-eye view of internal diversity, agricultural potential and constraints that decision-makers find easier to understand than a pile of single-theme maps. in this study, aez map of the karkheh river basin has been prepared usi...

Karkheh river is located in southwestern of Iran. Industrial and agricultural activities around the river contaminate it through its path. Water quality modeling from upstream of Shoosh city to downstream was simulated by QUAL2K model. In this study, we investigated how best to manage the quality of Karkheh river to be done. Nine parameters including BOD, COD, DO, PH, turbidity, nitrate, phosph...

optically stimulated luminescence (osl) is currently one of the most important dating methods. it dates the last exposure to sunlight. natural hazard evidences such as colluvial wedges, alluvial and fluvial sediments can be dated by osl. therefore, osl plays an important role in studies related to paleoseismology and tectonic activity, particularly in arid and semi- arid regions. the altai moun...

The Siberian elm (Ulmus pumila L.) is one of the most commonly found tree species in arid areas of northeast Asia. To understand the morphological and physiological characteristics of Siberian elms in arid regions, we analyzed leaves from seven study sites (five arid or semi-arid and two mesic) in China, Mongolia and the Republic of Korea, which covered a wide range of average annual precipitat...
