Abstract

Introduction Iran is a dry country eith alittle precipitation, as that downfall average is under third of downfall average in world. Whiles Yazd province placed in dry and desert area and have 100 milimeter of precipitation in year. Yazd as one of industrial city in our country was confront el with upand coming prodedure of population and migration and this ascensional growth caused the requisition for water consumption increase. Requisition in creasing have been caused that the level of underground waters in mean have falled off equal of 16 meter in 30 years period. Thus, answering to onging requests and procurement of water required Yazd city led to the city for supplying needed water become connected to nonrenewable resources and out of penetration basin and for inhabitation of regional and national tension crisis in them selves re search program, responsibles set solutions for supplying needed water of city. Among of this programs can allude to water transfer from zayanderod fountainhead that started of 1369 year and exploitation program of that started in 1378. On this basis the aim of this study is valuation of Yazd city resistancs wise water resource bases on civil development models and determination of civil optimized population in 1395 year and on the basis of two swith from water's provision and consumption. methodology To this end, Urban development forms were examined by using library studies and then Sustainability models concerned with water and sewage network were identified and the status of water resources in Yazd province and Yazd_Ardakan plain as well as Yazd city were determined by using relevant documents and then quantitative analysis were conducted to calculate the optimal population of the city based on two options for production and consumption of water. The type and manner of this research is descriptive and analytic and under the care of targeting essence and aim s achievement tools we was used of combinational qualitative and quantitative analysis. In this direction with using of librarian researches, civil resistant form's was studied and in continuation, resistance models about to civil's sewage and water system be identified. Situation of province's water sesources, ardakan-Yazd plain and Yazd city was determined by relevant document and then by using of auantitative analysis, city optimal population based on water production and water consumption be counted. Results and discussion The present research, first of all, is devotes to the assessment of Sustainability of Yazd concerning water resources based on sustainable urban development models and then touches on the optimal population of Yazd according to the options for water supply in 2016 with regard to the water transferred from Zayande rood to Yazd and examines the second phase of water transfer as well as water transfer project from Persian Gulf based on goal setting which applied mixed research method. . in first step for determination of water deficit rete in the inhabitan population calculated difference of water need average from inhabitant population (44. 9 milion cubicmeter in year) of production capacitance that water deficit for inhibitant population is founded. In second step for determinatiosn of excess population water deficit rate in the in habitant population (30. 3 milion cubuc meter in year) calculated equivalent to 83 milion liter minated 357000 unit and optimum population in 1395 under the care to produced capacitance (with out numeration of transitional water from zayanderoon) calculated 218000 unit. More over determination of optimum population in 1395 year that altogether 44. 2 milion cubic meter produced. In sequler, for determination of excess population water defict from inhabitant population (0. 5 cubuc meter in year) That is calculated 1369000 liter a day and based on percpita formula excess population. 59000 unit is achieved and optimum population under the care of pro non de centralization for removing deficit of needed water bases on this case in addition of transitional water from duces capacitance in this case 525000 unit is calculated. Thus, even if exterior dependence to city permeation basin(zayanderood water ) we will meet to water deficit and population excess. Whiles transitional water from in long tern isn’ t reliable and is un like to resistant development principles. In the vent of population non decentralization, for removing deficit of needed water based on this case in addition of transitional water from zayanderood simultaneous. With second phase of transitional water project of behesht adad and also Persian guif with better sped is did. Foregoing ingredient gatherum besides embedment of Yazd in dry region caused than water provision and distribution of this city install in critical and friable conditions. thus for managing and planning of water resources may emphasize that addition population achieved is minimum population rate and should decentralize from Yazd city that actually isn’ t possible. Conclusion The results are demonstrated that Yazd – ardekan plain has just 2 percent of underground water resources. While 82. 58 percent of pronince civil population are inhabited in Yazd city and 80 percent of needed water is provided of surface resources that is appuratant to transitional. Water from zayanderod, this water resources in distance of 330 kilometer of Yazd city is located thus bsed on resistant civil models from hall ana viliams, Yazd isn’ t yesistant wise to civil water resources. Bases on disrelation to out of permeation basin, subsistence possibility isn’ t existed and even with dependence to out of permeating basing (transitional water from zayanderod ) has 59000 unit excess population. In this model for being confine of permeation basin request management and sewerage resumption, Emphasize to using of resources with subtraction of external dependence pattern. Evidently population decentralize as better policy along side promotion of people culture at using of water, deducation of consumption percapita, managing pf water system, deducation, of casualties, progressive incease of water rate price and deducation of domesticated consumption and more basic that percipotating drinkable water from consumption water can be effectual step in improvement of water resources situation.
