this study aims to assess the effect of grazing intensity on vegetation structure, soil nutrient concentrations and soil physical properties. the study was carried out in steppe rangelands of saveh, markazi province, iran. four sites with four grazing intensities including very high, high, moderate and non-grazed with the same ecological conditions were selected. to study various vegetation and...

The northwest of China has a shortage water resources, and classic sewage treatment techniques have high cost produce waste nitrogen phosphorus. In order to achieve inexpensive discharge standards, an anaerobic biofilm coupled with ABR technology was adopted as for normal rural wastewater in the arid semi-arid vicinity Northwest investigate its operational impact on China’s domestic wastewater....

The problem of salinization/spreading saline soils is becoming more urgent in many regions the world, especially context climate change. monitoring salt-affected soils’ properties a necessary procedure land management and irrigation planning aimed to obtain high crop harvest reduce degradation processes. In this work, machine learning method was applied for modeling spatial distribution topsoil...

Over the past decade, adverse impacts of climate change and excessive urbanization have contributed to several unfamiliar costly floods in Gulf Cooperation Council (GCC), especially Qatar. With limited historical rainfall records unprecedented precipitation intensities impacting efficiency hydrological models, multi-criteria decision analysis (MCDA) presents a suitable alternative approach asse...
