Determining peak flows for ungaged areas is difficult and involves high uncertainty. Advanced computer capabilities provided by geographical information systems and hydrologic modeling software are used for detailed determination of the parameters involved, both for simple methods as the rational...

Improving the treatment efficiency of a primary wastewater treatment plant(WWTP),in Alexandria, Egypt,was studied.In order to improve the treatment efficiency of the plant, different improving scenarios were proposed and evaluated. The improvement scenarios are: scenario 1,use of engineered wetland...

Analysis and simulation of the behaviour of gas turbines for power generation using different nonconventional fuels obtained from different renewable sources are presented. Three biomass-tobiofuel processes are considered: anaerobic digestion of biomass (biogas), biomass gasification (synthesis gas)...
