The aim of the study is to map urbanization growth using satellite imagery, Google imagery and GIS in Mafraq city/North Jordan. Landsat imageries of 1987, 2005 and Google Earth (GeoEye-1) imagery of 2010 were used in GIS environment to map the change in the urbanization at Mafraq city. Maximum likelihood algorithm of supervised classification was used to delineate two land use and land cover classes for the study area, namely: populated areas and non-populated areas from 1987 and 2005 imageries. On-Screen digitizing was adopted on Google Earth (GeoEye-1) imagery of 2010 to map the populated areas. The main change observed for the time period of 1987-2010 was that the urbanized areas have increased approximately by 7.14 km2 (approximately 23% of the study area). The population density within the study area has increased from approximately 965 inhabitants per sq.km in 1987 to 1808 inhabitants per sq·km in 2005 and reached 2146 inhabitants per sq·km in 2010. The increase in the populated area within Mafraq city has impacted the surface hydrology runoff which leads to diverting some Wadis to avoid passing through the city centre. Also, the increase in urbanization in Mafraq city has put more pressures on the waste water treatment plant and solid waste dumpsite that serve Mafraq city.展开更多

The total population ofJordanis 6,508,271.Jordanis rapidly facing a severe water supply crisis due to greater demands on a finite quantity of available water. If current trends continue, it has been estimated that the country will experience a chronic water shortage by 2020. Despite these shortages, water loss in the distribution network is relatively high where it reaches 46%. Mafraq Governorate has the maximum water loss. Continuous records and data for the period 1999-2004 for Mafraq water authority were investigated for the water supply and lose. Water losses were evaluated, and suggestions were given to minimize the loss.展开更多
