Analysis of coal combustion by-product disposal practices in an arid climate : leachate water quality
Coal combustion by-products (CCBs), produced from a large power plant in New Mexico, have been disposed of in a nearby coal mine since 1973. These CCBs consist of fly ash, bottom ash, and sludge from the flue gas desulfurization process and have elevated concentrations of hazardous constituents. …

Assessment of the effect of climate change in anticipated water resources availability in arid climate zones
Climate change impact and drought phenomena linked with anthropogenic pressure have become a growing concern for water resource managers and policy makers, particularly in arid and semi-arid regions. This research proposes generic methodologies to evaluate the prospective impact of such changes at …

Mixed Carbonate-Siliciclastic Sequence Development and Chemostratigraphy On a Distal Foreland During Miocene Glaciation, Eastern Saudi Arabia
… by lowered sea levels, and moderately humid to arid climate. Rising sea levels pushed the siliciclastics updip allowing mixed siliciclastics and carbonates to form downdip, under semi-arid climate and locally hypersaline conditions. Maximum transgression slightly predated the Middle Miocene …

Investigation of the impact of desalination on the salinity of the Persian Gulf
… sea located in a region of Southwest Asia with arid climate. Because of this aridity, evaporation from the Gulf is extremely high (1.84 meters per year) and far exceeds the sum of freshwater inflow to the Gulf, mainly from precipitation and some from river flow. A residual circulation exists …

Geomorphology and ecohydrology of water-limited ecosystems : a modeling approach
… topographic slopes as rainfall increases in dry climates. Moving along a climatic gradient to wetter climates leads to the point where the effect of vegetation is overwhelmed by increasing runoff, thus erosion efficiency increases and slopes decrease. This transition in vegetation controls …

An urban weather generator coupling a building simulation program with an urban canopy model
… intended to integrate building energy and urban climate studies for the first time. It is based on the premise that at the same time buildings are affected by their urban environment, the urban climate is affected by the energy performance of buildings. To predict this reciprocal interaction, the …
