A generic hydrological model for a green roof drainage layer.
A rainfall simulator of length 5 m and width 1 m was used to supply constant intensity and largely spatially uniform water inflow events to 100 different configurations of commercially available green roof drainage layer and protection mat. The runoff from each inflow event was collected and sampled at one-second intervals. Time-series runoff responses were subsequently produced for each of the...
متن کاملEffect of P-Reactive Drainage Aggregates on Green Roof Runoff Quality
The main hypothesis of the presented study is that the negative effect of phosphorus leaching from a green roof substrate can be reduced by including P-reactive material in a drainage layer. In this work, different aggregates (Pollytag, lightweight expanded clay aggregates, chalcedony, serpentynite and crushed autoclaved aerated concrete) to be used as the green roof drainage layer are describe...
متن کاملResearch Work on Torrential Rain and Typhoons
Heavy rains and typhoons cause major disasters, including great economic losses and casualties, in China. Therefore, it is very important to research these torrential rains and typhoons in order to improve forecasting accuracy to mitigate their consequences. The Center of Disaster Reduction of the Chinese Academy of Sciences has cooperated with the Department of Atmospheric and Oceanic Science ...
متن کاملDesign and Development of Low P-Emission Substrate for the Protection of Urban Water Bodies Collecting Green Roof Runoff
Urbanization leads to higher phosphorus (P) concentration in urban catchments. Among different stormwater retention measures, green roofs are the least efficient in phosphorus retention. Moreover, much research has shown that green roofs act as sources of phosphorus, and they can emit P in significant loads. In this study low P emission green roof substrate was developed based on the proposed s...
متن کاملPerformance evaluation of green roofs in urban runoff reduction
Urbanism directly affects the hydrological cycle. One of the ways to manage runoffs in urban areas that is considered nowadays is green roof creation. Green roof is mainly created in humid and semi-humid areas, and efficiency of green roofs in arid and semi-arid areas has attracted less attention. In the current study, to evaluate the effect of green roof in arid and semi-arid to reduce runoff,...
