استخدمت طريقة دراستيك لتقييم الحساسية الكامنة للمياه الجوفية في حوض اللاذقية باستخدام ArcGIS 9.2 حيث تم تطوير نظام دراستيك المعدل بدمج استعمالات الأرض و تقسيماتها مع نموذج دراستيك العام, و بالمحصلة تم تنميط القيم النهائية لدراستيك في صفين اثنين (منخفض الحساسية و معتدل) و قد تبين أن إدخال المعايير البشرية قد زاد من الكمون بالنسبة للحساسية المعتدلة للمياه الجوفية. بالنتيجة النهائية فقد أظهر المضمون العام لخارطة الحساسية التي تم إنشاؤها لحوض اللاذقية, سيطرة صف الحساسية المنخفضة في المناطق الشمالية الغربية و الشمالية الشرقية التي تتمتع بأعماق توضع كبيرة للمياه الجوفية و ارتفاعات طبوغرافية عالية, بينما سيطر صف الحساسية المعتدلة في الأجزاء الجنوبية من منطقة الدراسة (المنطقة السهلية) التي تتميز بانتشار نشاطات بشرية متنوعة و بأعماق توضع لمنسوب المياه الجوفية قريبة من السطح.
The Drastic method has been used to assess the potential sensitivity of the Groundwater In Lattakia basin using Arc GIS 9.2 Where the modified Drastic system has been developed by combining the land uses and its divisions with general Drastic model .As a result, final values of Drastic have been modulated into two categories "low and moderate sensitivity" It has been found that the introduction of the human criteriahas increased the potentialof the moderate sensitivity of the Groundwater. As a final result, the general content of the sensitivity map which has been establishedfor Lattakia basin, showed, the domination of low sensitivity category in the north western and the north eastern areas which has big location depths of the Groundwater and high topographic altitudes.In contrast, the moderate sensitivity category dominated in the southern areas of the study region. The latter areas which are characterized by the existence of varied human activities havelocation ofGroundwater levels close to the surface.

The main goal of this study is to produce landslide sensitivity mapusing GIS at
Syrian Coast area.At the first stage of the study, 75% of the landslides locations (45
landslide locations) are used as training dataset and the rest was used as (15 la
ndslide
locations) the validation dataset. Fourteen input data layers were employed as landslide
conditioning factors in the landslide sensitivity mapping. These factors are slope degree,
aspect, altitude, plan curvature, profile curvature, tangential curvature, surface area ratio
(SAR), lithology, land use, distance from faults, distance from rivers, distance from roads,
topographic wetness index (TWI) and stream power index (SPI).
Using these conditioning factors, landslide sensitivity index was calculated.
Subsequently, the result was plotted in ArcGIS and landslide sensitivity map was obtained.
The produced sensitivity map is useful for general land-use planning.
The soil water erosion risk is one of the most important problems and
challenges facing the agricultural process in the Syrian coast today. The aim
of this study was to determine the spatial distribution of dangerous areas of
water erosion in the
basin of the Mrqyieh River using CORINE model. To
achieve this objective, the first phase of the study was to evaluate the soil
erosion viability based on soil characteristics (soil texture, soil depth and
percentage of stones); these properties were classified according to their
influence degree on soil erosion. The potential risk erosion map was based
on crossing all information obtained from soil erodibility, erosivity index
and the degree of slope at study area by using GIS technologies. The land
cover map of the study was produced and classified to two classes
depending on soil protection degree. Then, an actual risk map of soil erosion
was prepared after crossing land cover and potential risk erosion classes of
study sites. This study showed that 14.8% of the studied area facing high
risk of soil erosion, while the soil risk was moderate in 40.4% and low in
44.8% of the study area. The highly risked erosion area was located in the
center, northern and northwest parts of the study area. Moreover, the study
confirmed that the land cover is the most influential factor on soil water
erosion. The results showed that the Corine model for soil water erosion
mapping is a highly effective and cost-effective approach
This research highlights the vital role of Pavement Management Systems integrated with Geographic Information Systems in planning and managing road maintenance in Lattakia, and getting a flexible local system by following a new method in processing a
nd viewing information that supports maintenance decision.
This study included applying a pilot project for managing pavement maintenance over a group of roads following The General Establishment for Road Communications. Those roads were divided to links and segments then evaluated using the " Asphalt Institute Method ", which gave us a numeric pointer that led in turn to the type of maintenance needed for a particular pavement. In this research, we depended on the Geographic Information Systems to design and build a comprehensive database, that reflected the present condition of the studied roads, and enabled us to store, analyze and document pavement surface condition and link it to the digitized maps of the studied roads. This guaranteed easy and direct access to various kinds of data and solutions as every segment appeared in a different color reflecting its conditions according to the theme of the map. By doing so, we could support the process of taking right maintenance decisions.
With the increasing population, the rising standards of living, industrial progress and
rapid technological advancement, solid waste has varied and increased in amount as a
result of various human activities. Thus, waste disposal has become one of
the main
problems facing cities and human populations because of the dangers posed by this waste
to the environment and natural resources and health. Therefore, the development of an
integrated management system for solid waste has become one of the most important
elements of urban development strategies.
Traditional management of municipal solid waste disposal, which includes
collection, transfer and backfilling or burning operations, has evolved the concept of
disposal of solid waste during the previous decades and begun waste management
programs that focus on the use of computer programs such as geographic information
systems, which help environmental planning for cities, and selection of the most optimal
and economical solutions and.
This study includes the use of geographic information systems software technology
in the planning and selection of the optimal paths to collect and relay solid waste
containers in the city of Latakia. In fact, selecting these routes undergoes the equations of
length and time as to choose the shortest path, taking into account traffic regulations and
diesctions in the streets. As for time, it takes the shortest path in terms of speeds specified
for each road.
3D models of historical sites and monuments are very interesting in archaeology and digital tourism fields. These models help archeologists document historical sites and analyze the relationships between their components. Moreover, 3D models constitu
te an attractive factor that encourages visiting sites and presents virtual information about cultural heritage.
In this paper, we propose an approach that uses capabilities of CAD (Computer Aided Design) and GIS (Geographic Information System) systems to construct spatial and semantic database for historical sites and modeling them in 3D. Users of the mentioned database can use it to gather information about sites and to navigate across them via the animation capabilities in GIS.
The proposed ideas will be applied on the historical site of Ras-SHAMRA in Lattakia. Spatial data concerning the site will be acquired form a topographic plan designed in 2004. These data will then be processed and introduced into GIS environment. ArcGIS software will be used to achieve an Archeological Information System (AIS) for the site and to construct a 3D model of the site and the royal palace.
