Now and in the future, many countries expect to face inadequate water resources to fulfil their recent environmental, industrial, domestic and agricultural water needs. The world population is expected to grow about 30% at the year 2025, getting 8 billion persons. The living standards are also anticipated to increase as a result of improving urbanization, communications and globalization. So, competition on water among the domestic, industrial, agricultural and other users will rise in unprecedented levels.The researcher studied feasibility study and records that were generated during the life of the Hilla – Kifl irrigation project so as to get some perception into the planning and implementation processes. The researcher made field visits concentrating on direct observation of unending and completed project activities. During the field visits, group discussions and interviews with project staff, farmers and resident engineer were held.The objective of this research is to define the extent to which the feasibility study aims and objectives of Hilla – Kifl irrigation project were met. It was also significant to find best lessons and practices learned so as to improve the design, planning and implementation of future irrigation projects.
Housing represents a major world wide problem, especially for developing countries. It is essential to construct suitable housing units that are appropriate for the continuing population increase. Many countries have applied construction (policies) that depended on the available material and human resources. These schemes aim at producing the greatest number of dwelling units that are suitable for the people who do not own units. The aim of this research is the scope of low cost dwelling units in general, and through the reduction of roofing cost. The objective of the research, Economical feasibility study for production precast units (ferro cement units) for roofs of low cost dwelling and compare the cost of the proposed system With other conventional roofing systems: roofing by (jack arching) and reinforced concrete. Fifteen units of Ferrocement with square shape and three different dimensions were cast and tested for load test, tensile strength, compressive strength and bending. The optimized dimensions were (750*750*20)mm and the capacity ranges from (13 to 17.7)KNM2.The cost of (1m2 ) of these units was (38292.4)I.DM2 while the cost of (1m2 ) reinforced concrete (58534.94(I.D and (51062.7) I.DM2 for (jack arching)
