“…These models, such as SLEUTH, require several inputs including Slope, Land Use/Cover, Excluded layers, Urban areas, Transportation and Hillshading, hence the name. Several reviews are available on the subject [19][20][21]. They show that the prevailing modeling techniques often include numerous biophysical, political and socioeconomic factors to capture the spatiotemporal complexity of urban growth.…”

Cities are poised to absorb additional people. Their sustainability, or ability to accommodate a population increase without depleting resources or compromising future growth, depends on whether they harness the efficiency gains from urban land management. Population is often projected as a bulk national number without details about spatial distribution. We use Landsat and population data in a methodology to project and map U.S. urbanization for the year 2020 and document its spatial pattern. This methodology is important to spatially disaggregate projected population and assist land managers to monitor land use, assess infrastructure and distribute resources. We found the U.S. west coast urban areas to have the fastest population growth with relatively small land consumption resulting in future decrease in per capita land use. Except for Miami (FL), most other U.S. large urban areas, especially in the Midwest, are growing spatially faster than their population and inadvertently consuming land needed for ecosystem services. In large cities, such as New York, Chicago, Houston and Miami, land development is expected more in suburban zones than urban cores. In contrast, in Los Angeles land development within the city core is greater than in its suburbs.

“…However in many urban areas, the recharge rate to groundwater is found to be higher than pre-urbanization rates (Lerner, 1990). High rates of recharge, combined with lower actual evapotranspiration, result in higher groundwater tables in many urban locations (Lerner, 1990;Foster et al, 1994;Greswell et al, 1994;Karnieli et al, 1984).…”

High perched water table conditions, typically at depths between one and 2.5 metres, have created problems, including the increased occurrence of slope failures along nearby coulees for the city and the University of Lethbridge maintenance engineers. The source of water leading to the development of water tables in this region was determined to be over-irrigation of urban turfgrass. Water table development in the Lethbridge region is related to high tudgrass infiltration rates and high volumes of water received in till of low hydraulic conductivity. A statistical relationship was observed between the logarithm of water percolating beyond the root zone and water table deoth. R6sum6Des conditions de nappe phr6atique suspendue d un niveau 6lev6, en g6n6ral a des profondeurs variant entre un et 2,5 mdtres, ont entrain6 des probldmes, entre autres un plus grand nombre de glissements de pentes le long de coul6es avoisinantes, pour les ingenieurs de l'entretien de la ville et de l'Universit6 de Lethbridge. On a d6termin6 que la source d'eau qui mdne a la formation de nappes phr6atiques dans la region vient de la surirrigation des pelouses en milieu urbain. La formation de nappes phr6atiques dans la 169ion de Lethbridge est liee aux taux d'infiltration 6lev6s des pelouses et aux volumes 6lev6s d'eau oui oenetrent les sols d faible conductivite hydraulique. Un lien statistique fut observe entre le logarithme de l'eau en percolation au-deld de la rhizosphdre et la profondeur de la nappe phr6atique.
