The so-called sponge city is a new era of urban stormwater management concept, refers to the can be like sponge, in adapting environmental changes and respond natural disasters brought about by rainwater has good elasticity, also called "water elastic city". international common term "low impact development system construction", which absorbs, stores, infiltrates purifies water when it rains, r...

Green roof systems could help reduce peak discharge and retain rainwater in urban areas. The objective of this study was to investigate the hydrological behavior a green system by using SEEP/W model. rainfall-runoff relationship within simulated results were compared with actual data from test bed for verify applicability SEEP/W. Then, verified model used simulate varying four factors (soil typ...

Green roofs are a sustainable solution to manage water runoff from rain events in urban areas. Modeling hydrological phenomenon of green is challenging because the difficulties characterize soil parameters, inducing uncertainties on these parameters. Soil parameter spread model and need be analysed better understand dynamics retention. For this purpose, retention capacity represented by Van Gen...

This paper presents an overview of observed distresses on low slope roofing systems collected for the Building Envelope Life Cycle Asset Management (BELCAM) project. The data include over 14,000 visible distresses from 600 roofs from seven different climatic regions across Canada. The distresses encountered for built up roofs, modified bituminous roofs and a limited number of single-ply roofing...
