Lake Hemrin is located in the middle east of Iraq, about 50 km from the Iraqi-Iranian border. The lake is the main fish source and provides water for nearby farms. However, due to various socio-economic and environmental management issues, the Hemrin system is a difficult water resources challenge. Moreover, Lake Hemrin receives floodwaters annually over its storage capacity; therefore, there is a risk of flooding in the areas downstream of the lake. To this end, this research developed optimization solutions to design flood escape paths in the area using Analytic Hierarchy Process (AHP) and Genetic Algorithm (GA). Among three initial proposals, i.e., Adhaim River, Wadi Naft, and Salahdin, the developed models optimized each of the proposals and suggested that Wadi Naft would require only 3.88 km3 of cut and fill volume compared to Adhaim River of 34.33 km3. However, the latter would serve more people and agricultural lands. GA and AHP techniques to optimize flood escape paths have shown that these models can discover shorter pathways requiring less cut and fill costs while retaining other flood escape features. The proposed optimal flood escape path can substantially influence the construction of flood-prevention strategies in the area.

The religious endowments are one of the important sources, which acquire historical, cultural, and economic importance in all countries of the world. In particular, a religious endowment in Iraq includes several distributed real estates and lands that usually require efficient management systems. One of the most important factors affecting the management of real estates that belong to religious endowments is the rental amount of each real estate. In general, the estimation of the rental of real estates can support the future development of religious endowments. Governmental agencies are faced with some challenges in the management of religious endowments in terms of rental pricing due to numerous economic and geographic factors. The rapid development of artificial intelligence systems and Geomatic techniques can present a framework for rental amount estimation based on spatial and non-spatial factors. In this study, a machine learning algorithm (Support Vector Regression) will be combined with Geographic Information System (GIS) to predict and evaluate the rental amount of real estates that belong to a religious institution in Iraq (Shiite endowment in Hillah city). The final results indicated that the proposed method achieved an overall accuracy of 71%, a root mean square error of 0.2257 million Iraq, Dinar (IQD), and a correlation coefficient of 0.9272. This study can be used as an effective tool for the decision-makers to plan and manage the religious endowments in developing countries.

Engineering and Technology Journal, 2018, Volume 36, Issue 11A, Pages 1148-1157
DOI: 10.30684/etj.36.11A.3

In this paper, geomatics techniques were used to collect, build, and analyze a geo-database of the bus transport network. Spatial identification of bus routes and bus stops using GPS was performed using GIS to link and analyze the necessary metadata with the available spatial data. The criteria used to assess bus service coverage were as follows: the spatial coverage in terms of the walking distance to the transport service, the adequacy of the transport network length, and extent of supply availability of the bus transport system. The results revealed that the population “living in 47% of the city’s urban area” could arrive at a transport service within a period of less than 5 minutes (in other words, a walking distance of less than 400 m), which is the typical time to arrival. Furthermore, the study concluded that the current length of the transport network is sufficient to provide typical spatial coverage for the city's entire urban area if redistributed.

The Cadastral maps are very important since they have technical and materialist specification of the property borders. However, these maps despite their use as land registration in world in general but in Iraq; the old maps are unfit for use. Therefore, updating and digitizing the cadastral maps are very pivotal. In the present work, we have an old agricultural cadastral map since thirties as a hardcopy which was digitized then updated using control points and modern satellite image (QuickBird 2009) for the same area. In this research, we upgraded the methodology for updating of the agricultural cadastral maps of Iraq based on the use of Differential Global Position system (DGPS), Total Station, and Satellite Imagery, in addition to the cadastral editor extension in ArcGIS software to produce new agricultural maps. The tolerance of this approach was tested by root mean square errors in addition the parcel points were compared with land records and QuickBird image. The motivation of current work was due to there are no modern cadastral maps for the study area, which is located in province of Wassit South-East of Baghdad. The results can be used as a basis for the decision makers in addition; this methodology can be utilized to solve problems relating to land property in study area and can be extrapolated to other datasets.

One of the serious and growing potential problems in most large urban areas is the shortage of land for waste disposal. Although there are some efforts to reduce and recover the waste, disposal in landfills is still the most common method for solid wastes destination. Optimized siting decision reduces negative effects to residents living in its vicinity, thereby enhancing the overall sustainability associated with the life cycle of a landfill. In this study, candidate sites for an appropriate landfill area in Kerbala are determined by using the integration of Geographic Information Systems (GIS) and multi- criteria decision analysis (MCDA). Eight input digital map layers including urban centers, Hamlets, industrial areas, sub roads, wetlands, pipe line, soil characteristics, and surface water are produced using a geographical information system. Simple additive weighing method (SAW) within (MCDA) is used to analyze the prepared maps and produce final suitability map. According to the digital maps produced by this method, the analysis results in selection of one landfill site located in the north of Kerbala city. The area of landfill site selected is 6,800,000 m2 and, its volume is 20,400,000 m3.

This study was conducted to determine the land cover changes between year 1976
and year 2011 in Karbala Governorate by using an integrated approach of remote
sensing data and GIS applications for investigation of the spatial and temporal
changes. A part of Karbala Governorate, whose Area is 768 km2 was selected as study
Four cloud free Landsat MSS, TM, ETM+, and SPOT scenes covering the study
area were selected for analysis. Images were acquired in years 1976, 1990, 2001, and
2011 respectively. All images which mentioned above are rectified and registered in
Universal Transverse Mercator (UTM) projection zone 38 N and supervised image
classification system has been observed to classify the images in different land cover
categories. Six land cover classes have been identified and used to determine the
change in land cover in study area and these classes are: Agricultural land, Water
bodies, Urban Area, Sand dunes, Bare soil, and Waterlogged Area. According to the
results obtained from statistics of classification, it was observed that most changes
occurred in heterogeneous agricultural areas. It is thought that the main reasons of this
change are increasing population pressure, increasing sand dunes, appearance and
increasing waterlogged area and changing economic activities. Those reasons have
been led to the decrease of the agricultural areas in study area during period from year
2001 to 2011.

Prepare of Mapping the Distribution of Schools in Kut City Using Geographic Information System (GIS)

Engineering and Technology Journal, 2011, Volume 29, Issue 16, Pages 650-663

The increased rates of urbanization have resulted in doubling the number of schools in
in the city randomly, which resulted in building schools lacking the most appropriate
standards required like being fit with the convenient environmental and health conditions
or being away from natural and human dangers, because of the great abilities that the
geographic information systems gives which help in finding the most appropriate
solutions and making the best decisions, especially with regard to processing and analysis
of spatial information. Thus, the current research aims at using GIS in assessing the
current status of school sites in all stages of primary intermediate and high school,
according to a set of natural, human and social standards. As well as the employment of
GIS to document the locations of the current distribution of schools in the city to produce
digital maps of sites and the pattern of distribution of schools subject to update, then it
suggests amending some of the sites according to the degree of suitability criteria in
research. To achieve these aims, the research depends on the data available at the
directorate of education in wassit, in addition to the field survey to identify the location of
schools accurately using GPS and updating the data available. The research finds the
existence of concentration in the distribution of schools which is concentrated in some
regions, random in others or regular in others. In general, this distribution may not reflect
a situation similar to the distribution among all regions in the city.

Hussein H. Karim; Hussain Z. Ali; Ahmed H. Hamdullah

Engineering and Technology Journal, 2010, Volume 28, Issue 2, Pages 236-252

The conventional remotely-sensed satellite imagery is suited for regional
investigations in areas of good exposures which are reduced in southern Iraq due to
vegetation, water – covered areas and flat terrains. An imagery produced from
digitally processed geophysical data is an extremely powerful technique for
identification of geological features in such areas of extreme economic importance .
By utilizing an appropriate digital processing, the geophysical contour maps have
been converted to geophysical images. Images produced from digitally processed
geophysical data (gravity and aeromagnetic) have been analyzed by polynomial
filtering ( using several degrees ) allow major features to be delineated clearly. An
integrated image of gravity and aeromagnetic data sets has been produced using the
best of polynomial filtering ( 6th degree residuals ) . The interpretation of final output
images shows the association of negative gravity and magnetic residual anomalies
with some anticlinal structures , while positive residuals are associated with the
others. The positive residuals could be due to basement uplift , and the reversed
values could be due to deep- seated light core probably salt beds. Basrah depression
exhibits negative residuals.

Engineering and Technology Journal, 2009, Volume 27, Issue 10, Pages 1952-1965

Synergistic display of data recorded by different remote sensing has proved
extremely valuable for the extraction of geological features such as lineaments .
Accordingly , two satellite images were used for lineaments analyses which are
considered as indicators for rock fractures . Image resolution merge and
directional filtering methods were applied for lineaments extraction using GIS
techniques .Rose diagram and lineaments density analysis were used for the traced
lineaments . The output of these techniques are used to trace new lineaments as a
regional lineaments map . a synergistic display of these regional lineaments with
geophysical images allows the major lithological and structural boundaries to be
mapped . Evaluation of lineaments map and its rose diagram analyses shows that
the dominant lineament trend is mainly NW-SE and NE-SW. It is concluded that
these lineaments indicate the fault zones within the area. Besides, a considerable
conformity has been noticed between the location and dimension of such
lineaments with subsurface anomalies appeared in geophysical images

Adnan A. Alsamawi; Abdul Razzak T. Zboon; Aumar Alnakeeb

Engineering and Technology Journal, 2009, Volume 27, Issue 1, Pages 81-95

Generally In this paper, Baghdad Municipal Solid Waste (MSW) Generate for
five years period (from year 2006 to year 2010). This Period are estimated as a minimum
duration of landfill site operation time. Geographic Information System (GIS) technique
are used to prepare digital map of Baghdad city to determine all of Baghdad ten districts
areas and its geographic distribution. Population size forecasting are interpolated to find
urban population size of each district and its population density. Depending on economic
studies of population wealth variation of Gross Domestic Product (GDP) and the
adopted percentage of the chronically poor population in Baghdad which could
reach 40% in some districts, the individual waste generation rates of each districts
are assumed to ranged between 0.3 and 0.8 kg/capita/day. A value of 0.63
kg/capita/day is concluded for the year 2006 and increase it at a net rate (growth
rate less waste reduction rate) of the expected GDP increase of 4% per year to
reach 0.74 kg/capita/day in year 2010. Comparison between the obtained estimation
with other studies for other countries, puts Iraq in class of middle income countries.
