Research ArticleOpen accessPhrase in the titleDetermining Potential Sites for Runoff Water Harvesting using Remote Sensing and Geographic Information Systems-Based Modeling in SinaiHossam H. Elewa, Atef A. Qaddah, Ayman A. El-FeelProblem statement: Sinai is increasingly suffering from an overwhelming water crisis. Runoff Water Harvesting (RWH) could be a solution for this problem. The determined promising drainage basins for RWH could be used by the decision makers to propose appropriate controlling systems to overcome the problem of water scarcity and for implementing runoff farming and rain-fed agriculture. Approach: Remote sensing, geographic … …American Journal of Environmental Sciences, Vol. 8, Issue 1 · 15 Feb 2012 · 8,483 accessesView PDFCite
Research ArticleOpen accessPhrase in the titleIntegrating Gene Expression Programming and Geographic Information Systems for Solving a Multi Site Land Use Allocation ProblemKhalid A. EldrandalyProblem statement: Land use planning may be defined as the process of allocating different activities or uses to specific units of area within a region. Multi sites Land Use Allocation Problems (MLUA) refer to the problem of allocating more than one land use type in an area. MLUA problem is one of the truly NP Complete (combinatorial optimization) problems. Approach: … …American Journal of Applied Sciences, Vol. 6, Issue 5 · 31 May 2009 · 7,849 accessesView PDFCite
Research ArticleOpen accessIn the keywordsAssessing the Environmental Impacts of Urban Growth Using Land Use/Land Cover, Water Quality and Health Indicators: A Case Study of Arequipa, PeruOswaldo Villena Carpio, Brian D. FathProblem statement: This research assesses the direct effects of urban expansion on land cover/use, river flow, water quality and the indirect effects of these variables in the rate of gastrointestinal disease in people in Arequipa, Peru through the combined use of satellite remote sensing and geographic information systems. Approach: It also uses information about demographic changes, hydrologic data and land … …American Journal of Environmental Sciences, Vol. 7, Issue 2 · 26 May 2011 · 8,741 accessesView PDFCite
Research ArticleOpen accessIn the keywordsEvaluating the Implementation and Effectiveness of GIS-Based Application in Secondary School Geography LessonsAli DemirciThe purpose of the study was to investigate the barriers preventing the use of Geographic Information Systems (GIS) in secondary school geography lessons and to determine its effectiveness on students’ success. A workshop focusing on ways to implement GIS-based application in the classroom for 14 teachers from nine high schools was conducted in 2006. The teachers were given GIS software, … …American Journal of Applied Sciences, Vol. 5, Issue 3 · 31 Mar 2008 · 8,110 accessesView PDFCite
Research ArticleOpen accessIn the keywordsThe Effects of the Degree of Soil Salinity and the Bio preparation on Productivity of Maize in the Shaulder Irrigated MassifMaksat Nurbaiuly Poshanov, Shakhislam Uzakbaevich Laiskhanov, Zhassulan Maratovich Smanov et al.During the study on the Shaulder irrigated massif, the soil salinity maps with different degrees of salinity were compiled at the large-scale 1:10000 in the GIS environment. It was found that the area of saline soils increases with depth. In the upper 0-20 cm layer, 29% is salted and in the 50-100 cm layer, up to 44% is salted. The … …OnLine Journal of Biological Sciences, Vol. 22, Issue 1 · 11 Feb 2022 · 6,737 accessesView PDFCite
Research ArticleOpen accessIn the abstractRandom Forest and Extreme Gradient Boosting with Bayesian Hyperparameter Optimization for Landslide Susceptibility Mapping in Penang Island, MalaysiaDorothy Anak Martin Atok, Soo See Chai, Kok Luong Goh et al.Landslide susceptibility models often face challenges of overfitting and overestimation. This research focuses on improving the predictive capabilities of the Extreme Gradient Boosting (XGBoost) and Random Forest (RF) algorithms by applying Bayesian Hyperparameter Optimization (BayesOpt). Penang Island, a region in Malaysia prone to frequent landslides, was chosen as the study area. Ten Landslide Conditioning Factors (LCFs), including elevation, slope angle, … …Journal of Computer Science, Vol. 21, Issue 10 · 16 Dec 2025 · 3,103 accessesView PDFCite
