Development and metabolism of the city of Khartoum (Republic of Sudan): spatial designing of the coastal territory of the Blue and White Nile

Abstract

The given article reveals the development of the metabolism of the city of Khartoum, the problems of influence on the microclimate improvement elements built up coastal territory of the Blue and White Nile in Khartoum. The study shows the microclimate formation factors of Khartoum, gives an assessment of the modern state of the microclimate of the coastal zone and its changes. The article indicates that, depending on the nature of use and planning organization of coastal territories microclimatic influence of water areas can propagate over appreciable distances to the city or limitation depth in a narrow strip along the coast. In urban areas the air temperature is considerably higher and the humidity is lower than in the coastal area especially in summer, this is due to differences in physical properties of water and land. Water has a higher heat capacity, high reflectivity, the wind speed increases and increasing the humidity of air masses passing over it. Thus, in order to improve microclimatic and hygienic conditions of coastal territories in Khartoum there is the need to use the favorable impact of the Blue and White Nile.
