Özet (Çeviri)
Changing environmental conditions and increasing urbanisation present new challenges to urban drainage systems that require new solutions and implementations. Such changes along with increasing public awareness about environmental issues paved the way for more sustainable solutions for urban drainage. In the last decades, concept of sustainable urban drainage has been adapted to the requirements of various different environments. A number of different solutions such as infiltration trenches, swales and permeable surfaces were presented over the years. As part of sustainable urban drainage systems, permeable pavement systems play a crucial role in urban drainage. Adaptability, stormwater retention and pollution control capabilities of permeable pavement systems make them a strong replacement option for impervious surfaces in urban environments. However studies and experiences have shown that performance issues do hinder the capabilities of some applications. Clogging of system mainly caused by particle accumulation has shown to be the primary challenge that permeable pavement systems face. Such is that some applications with expected effective life of 20 to 30 years were performing with rates less than adequate after 5 years of use due to clogging. Much is yet to be uncovered about the hydrological processes of permeable pavements. Clogging mechanics, how it occurs and factors that influence it are among topics that require more research. This study attempts to uncover more about clogging mechanics and suggest optional designs that would increase the effective life of permeable pavement systems. Using previous studies and data obtained by other researchers, a representative environment was created in this study. Different variables in play were analysed using hydrological models and formulas. Results obtained were used to provide detailed analysis and interpretations regarding hydrological processes. Findings of these tests include the role of urban sediment characteristics present in urban stormwater and performance comparisons of suggested design modifications. As a result, this study has revealed the significance of size and mass of pollutants on infiltration rate. To counter clogging, modified paver block designs were introduced. Both advantages and disadvantages of modified designs were presented, and to conclude, recommendations for further studies were presented.
