ABSTRACT Vehicular exhaust emissions are a dominant source of air pollution and contribute significantly to greenhouse gases and human health problems. An improved dispersion model designed to estimate pollutant concentrations near travel ways of urban streets was developed and its performance evaluated. The model has four inbuilt parameters namely; the aerodynamic coefficient, the wind speed offset, the effective release height and the street wind turbulence coefficient. The model was calibrated ...

ABSTRACT Wildland fire spread is one of the most challenging problems faced by reserved or unreserved vegetation in many developed and developing nations, because it can lead to serious environmental hazards in claiming lives, properties, animals and some other valuable treasures. This thesis establishes an approximate analytical solution that is capable of analysing fire spread in a real-time coupled atmospheric wildland fire, in determining the effect of temperature, oxygen concentration, ...
