Interest in arid ecosystems as a source of food supply for rapidly increasing population of the world, on the one hand, and the problems pertaining to the climatic characteristics, water shortages and soil sensitivity for the inhabitants in such areas, on the other have prompted efforts at both national and international levels to develop a better understanding of these problems as well as to f...

Estimating actual crop water requirement and irrigation schedule are essential for designing of the irrigation systems, storage construction and water conveyance structures. Many models have developed for estimating crop water requirement. Although most of these methods need different climatic parameters, providing and forecasting all of these parameters always are not available. Most of the ti...

Abstract Traditional Iranian architecture principles have deep roots in this region’s culture, thoughts, and climatic conditions. Privacy, as one of these principles, which has ever regulated all aspects life, been beautifully embodied the vernacular residential Iran. It proved to profound effects resulted a specific spatial organization house placement various functions, either private or semi...

a r t i c l e i n f o Groundwater is considered as the most important natural resources in arid and semi-arid regions. In this study, the application of random forest (RF) and maximum entropy (ME) models for groundwater potential mapping is investigated at Mehran Region, Iran. Although the RF and ME models have been applied widely to environmental and ecological modeling, their applicability to...

Estimating evapotranspiration (ET), the main water output flux within basins, is an important step in assessing hydrological changes and availability. However, direct measurements of ET are challenging, especially for large regions. Global products now provide gridded estimates at different temporal resolution, each with its own method estimating based on various data sources. This study invest...

Abstract Climate change is the most important challenge in achieving sustainable development. Semi-arid and arid areas (such as Iran) are particularly susceptible to effects of climate on water supply. In this research, effect upstream land use investigated Tajan, a river north Iran. The data regarding were produced via second-generation Canadian Earth System Model (CanESM2) adopted input SWAT ...
