In increasingly expanding cities, roofs are still largely unused areas to counteract the negative impacts of urbanization on water balance and reduce flooding. To estimate effect green as a sustainable low impact development (LID) technique building scale, different approaches predict runoff carried out. hydrological modelling, representing vegetation feedback evapotranspiration (ET) is conside...

U radu su izrađeni modeli vodovodne i atmosferske kanalizacione mreže u naselju Sefkerin. Na osnovu potreba korisnika, hidrauličke analize formirana je vodovodna mreža. Proračun hidraulička analiza sprovedeni okviru programskog paketa EPANET. Kanalizaciona mreža trasirana zavisnosti od topografskih uslova, dok dimenzionisanje izvršeno na padavina dvogodišnjeg povratnog perioda. Hidraučilčki pro...

Water management in urban areas of developing countries is a major environmental challenge for the future. Within the framework of the IWA Cities of the Future Programme, current water and wastewater management systems are investigated in Kayseri, Turkey, with the purpose of bringing water into the center of city life by a reformed pilot project. In order to assess both the quantity and dynamic...

Permeable pavements are a green infrastructure stormwater management practice that can serve as functional component of the site design. However, previous field studies suggest high uncertainty in parameters used for performing hydrologic calculations permeable pavements. The Environmental Protection Agency (EPA) Storm Water Management Model (SWMM) within PCSWMM software package was to simulate...
