Then, suggestions for improvement of groundwater quality in Syria are evaluated. Syria is located in a region where water scarcity is dominant. About 87% of all water in Syria is mainly used for irrigation, with almost 60% of this water taken from groundwater resources. The rest is used for domestic and industrial purposes, which account for 9% and 4%, respectively. Due to over-pumping and the increase in the number of unsustainable wells observed in recent decades, groundwater is quantitatively deteriorating. In general, sources of groundwater contamination fall into two main categories: natural and anthropogenic sources. Important sources of natural groundwater pollution include climate effects. About 43% of groundwater has a high concentration of SO4 and/or NaCl. This is specifically dominant in the eastern region of Syria due to the harsh environment where precipitation is relatively low, and evaporation is high. One of the major sources of anthropogenic groundwater contamination is civil war. Most of the damaged regions are located on permeable rocks, which increases the probability of groundwater contamination due to chemical weapons (CW) used. It is vital to manage and control groundwater resources well. With the increase in water contamination and with the absence of poor water management, access to drinking water will be more of a problem than it is now.Conference Object A Decision Support System for Assessment of Land-Use Changes, the Case of Izmir(LookUs Scientific, 2013) Yazdani, Hamidreza; Saygın, ÖmürLand-Use changes and their possible impacts over time as consequences of proposed urban developments are one of main concerns of planners in planning process. Understanding the impact of these changes on environment is a crucial issue in the planning approach aims to achieve the sustainable urban development. A Planning support system (PSS) is mainly based on collecting, monitoring, analysing data and evaluating the impacts of alternative planning scenarios using Geographical Information Systems (GIS) This paper offers an approach to evaluate the interoperability of a model based on the data sets to be explored. Considering the integration of satellite imagery, field survey and plans where adequate local data set is missing and modifying the model to evaluate best represented data increase reliability of a model. For this propose this study modifies "ESRI Smart Land-Use model (LUCIS)" for the data represented region meanwhile integrates the data sets for the most accurate representation This model based on best presented data provides crucial decision guidelines for decision makers in testing development scenarios. Different PSS's have different algorithms and underlying assumptions. Consequently Comparing results of several PSS (ie. CommunityViz, What-If) for the same purpose could be more reliable than testing a single model in a project Further research should be conducted via web-based monitoring system that would improve collaboration of different interest groups.
