Role of water in urban planning and management

Abstract

Urbanization-the concentration of people in urban areas and the consequent expansion of these areas-is a characteristic of our time. It has brought with it a host of new or aggravated problems that often make new demands on our natural resources and our physical environment. Problems involving water as a vital resource and a powerful environmental agent are among the most critical. These problems include the maintenance of both the quantity and quality of our water supply for consumption, for recreation, and general welfare and the alleviation of hazards caused by floods, drainage, erosion. and sedimentation. A prerequisite to anticipating, recognizing, and coping intelligently with these problems is an adequate base of information. This series of reports is intended to show the relevance of water facts to water problems of urban areas and to examine the adequacy of the existing base of water information.

GIS-based analytical modeling on evaluating impacts of urbanization in Amman water resources, Jordan

“…(AE) = (p) • (0.457 • (T) mean + 8.128) (3) However, (p) value in the above equation is the actual daily daytime hours to annual mean daily daytime hours expresses as a percent (Schneider et al 1973).…”

“…For the runoff, we used a coe cient that changes by the land cover and landforms the main two factors that controls overland ow in our case study. Accordingly, we classi ed the studied area with different runoff coe cient as follows (Schneider et al 1973, Butler and Davies 2000):…”

“…Urban area expanding because of inhabitants increasing is a common process in the capital cities such as Amman (Schneider et al 1973, Butler 2000. However, previous studies show that urban expanding in Amman due to the population growth has increased the urbanized area from about 147 km 2 in the year 1987 to 237 km 2 in 2014 that means the urbanized area increased by almost 61% over the last three decades.…”

“…The rst and the second gulf war in the 1990's forced more refugee waves to migrate to Jordan in general and to Amman speci cally and the population becomes 851,000, and 1,017,000 inhabitants respectively. In 2014 the population of Amman become 1,698,000 after the migration of Syrians due to the civil war.Urban area expanding because of inhabitants increasing is a common process in the capital cities such as Amman (Schneider et al 1973, Butler 2000.

Water quality problems of urban areas

“…As Schneider et al (1973) have aptly noted, water is both an artery and a vein to urban life. As Schneider et al (1973) have aptly noted, water is both an artery and a vein to urban life.…”
