2. 1. Soil Salinity and Crop Yield at El-Salam Canal Area, Egypt

   Author : Yasser Hamed Abd El Mageed; Avdelningen för Teknisk vattenresurslära; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; El-Salam Canal; Egypt; Salinity; Crop yield; Arid;

   Abstract : Soil salinity and solute movements through the soil are considered the most important challenge facing agriculture in Arid and Semiarid regions (e.g., Egypt). READ MORE

4. 2. Floodwater harvesting for artificial recharge of groundwater - estimation and prediction for arid Iran

   Author : Hossein Hashemi; Avdelningen för Teknisk vattenresurslära; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Artificial recharge; Groundwater modeling; Climate change; Spate irrigation; Arid area; FWS; GBP;

   Abstract : Groundwater depletion in arid and semiarid areas is of increasing concern. Increasing water demand due to increasing population and climate change impacts have intensified the water shortage problems and put further stress especially on groundwater. READ MORE

5. 3. Solid Waste Landfills in an Arid Environment : Site Selection and Design

   Author : Ali Chabuk; Jan Laue; Nadhir Al-Ansari; Sven Knutsson; Hussain M. Hussain; Roland Pusch; Rafid Alkhaddar; Luleå tekniska universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Landfill; Arid Environment; Site selection; Design; Babylon; Iraq; Soil Mechanics; Geoteknik;

   Abstract : Selecting landfill sites is considered a complicated task because its whole process is based upon several factors and restrictions. This study shows the present status of solid waste management, sources, collection personnel, machinery and equipment that are involved in the waste collection process, financing and financial management for the major cities of the Babylon Governorate in Iraq (Al-Hillah, Al-Qasim, Al-Mahawil, Al-Hashimiyah and Al-Musayiab).

6. 4. Potential Use of Aquifer Thermal Energy Storage System in Arid Regions

   Author : Qais Al-Madhlom; Jan Laue; Nadhir Al-Ansari; Sabbar Abdullah Saleh; Luleå tekniska universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Aquifer thermal energy storage system; ATES; site selection; seepage velocity; aquifer vulnerability; DRASTIC; arid regions; ArcMap GIS; Soil Mechanics; Geoteknik;

   Abstract : After the Oil Crises in 1973, which meant higher energy costs, the world started to look for other sources of energy. This led to the development of renewable energy techniques. Because of the intermittent nature of renewable energy, storage systems were also developed. READ MORE

7. 5. Morphometric and Landscape Feature Analysis with Artificial Neural Networks and SRTM data : Applications in Humid and Arid Environments

   Author : Amir Houshang Ehsani; Friedrich Quiel; Wolfgang Wagner; KTH; []
   Keywords : Self Organizing Map; Neural Network; Morphometric Feature; Landscape; Yardang; Lut Desert; Potential natural vegetation; geoecosystem; Landform; Landsat ETM ; Morphometric Parameters; SRTM; Resolution; Curvatures; DEM.; TECHNOLOGY; TEKNIKVETENSKAP;

   Abstract : This thesis presents a semi-automatic method to analyze morphometric features and landscape elements based on Self Organizing Map (SOM) as an unsupervised Artificial Neural Network algorithm in two completely different environments: 1) the Man and Biosphere Reserve “Eastern Carpathians” (Central Europe) as a complex mountainous humid area and 2) Lut Desert, Iran, a hyper arid region characterized by repetition of wind-eroded features. In 2003, the National Aeronautics and Space Administration (NASA) released the SRTM/ SIR-C band data with 3 arc seconds (approx. READ MORE
