The published studies about the water quality of Euphrates River in Iraq till now have been reviewed critically. The revision of the published researches depend upon several bases including the period of samples collection, the number of sampling stations, water samples collection method, the analytical techniques employed to measure and analyze the results. This critical study concluded that the need to follow a specific protocol in selection sampling sites, how the samples are collected, how samples are analyzed, and pay attention to quality assurance and quality control during sample collection, preservation and analytical procedures.
The research aims evaluates the water consumption and future demand by using the WEAP program. Five scenarios have been adopted, which is the reference scenario that showed the results of increase in water demand from (100) million cubic meters in 2015 to (397) MCM in 2035 with a water deficit in 2035 to (38) MCM. Modern irrigation methods reduce the water deficit from (38-2.9) MCM. While the use of underground water reduced the deficit from (38-26) MCM. As for the wastewater reuse scenario, the deficit decreased from (38-35) MCM. Reducing the per capita share did not reduce the water deficit.
In this study, the water evaluation and planning WEAP model was used to improve the Fallujah irrigation project with 63,000 hectares and an annual budget get 1,476 million m3/ yiod (2020-2021). The results showed the total Water used was 1,272 million m3/year and equaled 86% of Fallujah irrigation budget. The annual production was 524.4 million Kg/year for Fallujah irrigation, and total economic returns were 393.6 million $/year. The study outlined two scenarios for enhancing the irrigation system. The first scenario entailed implementing a sprinkler irrigation system for wheat and barley across all projects. This resulted in a production increase from 524.4 to 625.7 million kilograms per year and a corresponding rise in economic returns from 393.6 to 427.2 million annually. In the second scenario, a sprinkler system was adopted for wheat and barley and a trickle system for other crops. This approach led to production growth from 524.4 to 1164.9 million kilograms per year and a surge in economic returns from 393.6 to 559.4 million annually.
The development of cities in the infrastructure and urbanization and the increase in the population make people increase in the purchase of the private car, which in turn causes the congestion , pollution , accident and noise especially after 2003, as Iraq's import of cars increased to 5,800,000 cars distributed between the provinces, as 3Anbar province ranked ninth in the development number of cars with 174,000 cars according to the Central Bureau of Statistics of the Ministry of Planning. The university is the largest governmental institution that has the largest traffic volume of vehicles. We have three directions for entering the Anbar university they are east, middle and west directions. Total traffic volume from east, middle and west direction is 2165 vehicles which lead to traffic congestion in Ramadi city and Anbar university. The total traffic volume in private transportation in east, middle and west direction is 727,515 and 923 vehicles respectively. No of students in private transportation in east, middle and west direction is 4617, 3185 and3985 passengers respectively. As results of this research, there are three proposed parks one of them in the Sujaria at east direction, second park in Ramadi center at middle direction and third park in 5km area at west direction. In this paper, we make comparing between private and public transport in terms of fuel costs and time from the origin (the three proposed parks) to destination (Anbar University) assuming that private cars stopped in those three parks by using Park & Ride System and used buses with capacity of 40 passengers to transport students to the university. Depending on no. of passengers in private transportation from the three proposed parks to university we got the No. of buses from east park (Sujaria area), middle park (Ramadi center) and west park (7km area) to university which were 28, 20 and 25 bus respectively because each bus can transport four times.
minimizing the surface area of a reservoir during maximum evaporation losses period. A mathe-matical relationship linking the depth of water with the surface area of the reservoir has been formulated, and its integration can be used to estimate conservable water quantities. Reducing the water level in the reservoir to the minimum permissible level before the dry months has re-duced the evaporation losses by 65% and 51% for the two scenarios. These two scenarios have been conducted by assuming that the dry months start with the presence of the water level in the reservoir at a height of 14 and 12 m, respectively. On the other hand, evaporation losses during drought months have been decreased by 24%. By this technique, it can be possible to obtain wide areas suitable for agriculture, contributing to the economic and social development of the region. Also, Depth index(DI) suggested in this study and defined as the ratio of volume of the water in the reservoir to corresponding surface area, to compare the location of the best dam among the 13 proposed dams in Wadi Houran by reducing evaporation losses. The results of this index showed the best location was at DI=10.901 in DM 7, and the worst is at DI=2.425 in DM 8.
