تعد المصادر المائية و حجم توافر المياه المورد المؤسس لفهم محدودية مورد العمران؛ و إن أي اختلال في خصائص الموارد المائية يعكس أزمة عند توسع المدن و نمو سكانها و تنوع فعالياتها، غالباً ما يلجأ المخطط إلى إطلاق بعض التوصيات العامة عن استخدام المياه و اقتراح استراتيجيات بسيطة لمعالجة الخلل دون إعطاء الموقف الأهمية اللازمة. مما استرعى البحث دراسة مستقبل مياه مدينة دمشق ذات النظرة المقلقة، من خلال استعراض الدراسات العمرانية السابقة، و الاطلاع على دراسات الموازنات المائية المتعلقة بها، و سيناريوهات الزيادات السكانية المستقبلية الموضوعة، و انعكاسها على مناطق التوسع؛ بهدف اقتراح نظام لتخطيط، الموارد المائية المحدودة و تقييمها و تخصيصها، بين الاستخدامات الزراعية، و الحضرية و البيئية؛ بحيث تحقق التكامل التام بين العرض و الطلب و نوعية المياه، من خلال مؤشرات مدمجة، تمكن من وضع نموذج (موديل) يكون أداة للتخطيط المتكامل للموارد المائية؛ يمكن اعتماده في دراسة الاحتياجات المستقبلية من المياه في الأمد القريب و المتوسط و البعيد.
The water resources and water availability is main source for understanding the threshold of Urbanism resources limitation; and any imbalance in water resources specifications reflexes a crises for cities expansion, population growth, and activities variety, mostly the planner depends on providing some general recommendations about water uses and suggesting simple strategies for correcting the deficiency without considering the needed consideration. That drew the research to study ers Damascus the water of in city water future which should be worried about, throughout a review on the former urban studies and look at the related balance water studies and the adopted future population increase scenarios, and its impacts on the expansion areas; in order to propose a system for planning, evaluating, and allocating the limited water resources, between the agricultural, urban, and environmental uses; whereas full integration between supply, demand, and water quality will be achieved , throughout compact indicators, manage building a model (Model) which will be a tool for integrated planning method of water resources; can be adopted to study the future needs of water in the short, medium and long terms.

The research problem is the lack of urban policies which use smart cities technologies in solving urban
problems, especially transportation problems, so the research aims to develop a strategy to solve
transportation problems in Damascus using smar
t cities applications.
It starts by defining smart cities and its dimensions, then shows its basic applications, especially smart
transportation, its components, application challenges, and its role in solving transportation problems,
then it introduce similar experiments for the application of smart transportation systems, then it
concludes to a set of recommendations which contribute to solve traffic problems in Damascus through
the application of intelligent transportation strategy.

This paper analyzes the position and role of the mosque as a factor in the formation,
transformation and development of Muslim–inhabited cities, from many neighborhoods to the
entire city, and shows proof linking mosque structure with the structure
of a city and of
neighborhoods, while having the moral and material dimensions. In this regard, considering a
comprehensive view of the mosques in the structure and design of cities and neighborhoods, is
not seen as a single element of architecture, but as the role of historical mosques and religious
beliefs and changes from a traditional society to a modern one. However, in the form of urban
solutions, it is the physical development of the neighborhood, because the mosque has always
been an integral part of Muslim–inhabited areas and more than its constituent elements in
bringing about change and urban development.
This research aims to shed a light on the distinctive economic characteristics of water
resources and to identify the reasons that led to increasing interest in studying these
resources and their economics.
depending on descriptive analytical meth
od through characterization of what is and
analyze it, The researcher is addressing the policies necessary to be followed for a
successful allocation of water balances within the time periods, and define whether the
water resources are to be considered as an economical good and whether they are subjected
to market mechanisms, i.e. demand and supply.
the research results pointed out to the fact that the water resource is a strategic vital
resource and an economic good has a special nature which make it not subject to market
mechanisms.
this study is providing a number of proposals that emphasize the need to focus on the
economics of water resources to attain the efficiency of resource exploitation, which, on
the one hand, leads to achieving sustainability of this valuable resource, and on the other
hand fulfill maintain the economic development.

Because rainfall in the coastal area is high and water projects are nearly missing, we think it is important to make use of available water resources. In order to predict future rainfalls and suggest proper management of resources, we created a mathe
matical model linking rainfall amounts between demand (population, agricultural and industrial) on water resources during the period (2000-2012). Results show the following:
1. Rainfalls decreased during the period ( 2002-2012) at an annual rate of (1.84%).
2. Demand on water resources increased during the period (2002-2012) at an annual rate of (3.41%) of the population demand, and (3.47 %) of the agricultural demand, and 6.25% for industrial demand.
3. There is a surplus of available water resources and the size of demand for them, with the surplus decreasing during the period (2002-2012) at an annual rate (2.97 %).
4. The estimation of the surplus between the amount of available water resources and the size of the demand for them will decrease in 2023 from what it was like in the year 2013 at an annual rate (-3.23%).
