In this study, irrigation evaluation of different cultivars of Rapeseed and barley in 2017-2018 crop year was performed in Sharifabad farm of Qamroud section of Qom. The result led to optimization of cultivation and improved productivity water is in two products, Brassica napus and barley. The Groundwater EC of this farm is salty. Due to the salinity tolerance threshold of barley, barley was predicted without yield reduction. But in canola crop due to less tolerance to salinity, crop reduction was predicted. During one crop season, Brassica napus was cultivated in eleven cultivars by irrigation method, the planting date started from October 26 to October 17, In tape irrigation, it was irrigated between 10 and 13 times. The objectives of this study were a case comparison between different cultivars of Brassica napus, both foreign and domestic, resistance of cultivars to cold and water consumption and productivity and yield and most importantly a comparison between irrigation methods in terms of water consumption and water efficiency. Meanwhile, Hayola Shirazi cultivar had the highest yield among all cultivars in the type irrigation system with the lowest water consumption. The efficiency of this figure is about 0.77 kg/m3 was calculated in the type irrigation method with water efficiency of 0.66 kg/m3 compared to gravity irrigation (surface) which has a productivity of 0.20 kg/m3. In hydroflow irrigation, it performed better than the previous two methods, but consumed more water (about 34.2%) than type irrigation. Regarding barley, it was cultivated in three cultivars and two types of irrigation methods, Fajr 30 cultivar increases water productivity by 2.2 by irrigating the type.

In view of high population growth and water resources deficit in arid and semiarid area and groundwater resources shortage in mountainous area, there is an urgent need to identify the alternative sources of potable water. Fog is one of such sources of water. Although fog water yielding potential is largely ignored by water authorities, it was used extensively in ancient times and promoted the water productivity. The objective of this research is to review the fog collection in Yemen and South Africa. In El Tofo Mountain in Chagungo (Chile), 75 fog collectors were erected. According to the reports, production rates vary from zero on a clear day to maximum of 100000 liter per day. With this arrangement, each of the 330 villagers received about 33 liter of clean water per person per day. Geographical and climate characteristics, droplets distribution, and fog density need to be evaluated and are crucial factors for success of fog water harvesting project. Chemical and microbial studies of fog water harvesting show that the water quality is safe for human consumption. Thus, it can be considered as an alternative source of water in arid and semi-arid regions that dense fog could be available.

Nowadays water resources protection, by application of optimized, sustainable and economical approaches, for logical utilization of water has turned to one of the most vital and challenging issues worldwide. Additionally, water reuse, known as a strong factor in managing water crisis, is an appropriate alternative to handle this challenging crisis. This senior project discusses the design and construction of a solar water treatment system taking the advantage of ultraviolet (UV) radiation and a combination of natural processes. An UV wastewater treatment system is designed to demonstrate the wastewater treatment capability of the network. This system is specifically designed to eliminate bacterial contaminants and meet the needs of a community. Only sunlight is needed to power the treatment system. A solar panel collects energy from sunlight to be used for electrical consumptions such as pumping. Ultraviolet light disrupts bacteria and produces a source of drinking water. In fact, we try introducing an innovating idea of a decentralized solar wastewater treatment (DSWWT) machine, which is adaptable with environmental standards goals. In addition to being affordable and eco-friendly, it can be used in different kinds of communities (especially useful for remote communities).This machine will also be capable of being used in any residential, commercial or official building, which produces wastewater. Based on the assessments, manufacturing of this machine is easily reachable.
