In this paper, based on remote sensing image processing and SWMM simulation, we evaluate the effectiveness of a coupled LIDs system for the watershed scale. The main content and contributions include: 1) the extraction and classification of historical and recent LULC data (in 1979, 1989, 1999, 2009, 2017) of the study area and an analysis of the characteristics of the LULC change; 2) a watershed-based SWMM applied to the simulation of the runoff and an analysis of the runoff change characteristics; 3) the proposal and design of three coupled LIDs scenarios which treat runoff change as evaluation metric to systematically discuss the effectiveness of LIDs in the watershed. The results show that the combination structure and scale can significantly affect the coupled LIDs effectiveness. A system with multiple LIDs is more effective than one with only single LIDs. With the increase of spatial scale, the effectiveness of the coupled LIDs gradually weakens. Our research enriches the application scale of LIDs and SWMM, and can be beneficial to the construction of the "Sponge City", storm management and urban planning.

“…The input parameters of a DRAINS sub-catchment include: size, impervious (paved) area, supplementary paved area, pervious (grassed) area and travel time (or time of concentration) for runoff to concentrate at the catchment outlet [69]. The impervious area (road area and roof area), supplementary area (other paved, e.g., footpath and driveway) and pervious area of each sub-catchment were estimated from the Google map of Pipers Crest.…”

The contribution of this paper is a comparison of the installation cost of a conventional drainage system consisting of a network of pits and pipes, with that of a hybrid drainage system comprising a network of pits and pipes, supported by allotment scale infiltration measures in a modern greenfield residential development. The case study site is located in Pipers Crest, near Strathalbyn, South Australia. This as-built site consists of 56 allotments, 42 pits (hence 42 sub-catchments), one detention basin and over 1000 m of drainage pipes. In this study, conventional and hybrid (combination of conventional and Water Sensitive Urban Design, WSUD systems) drainage systems were designed to convey minor storm events of 10% annual exceedance probability (AEP), and checked for major storm events of 5% AEP, using the DRAINS model and/or source control principles. The installation costs of the conventional and hybrid drainage systems were estimated and compared based upon cost estimates derived from Australian literature. The results of the study indicate that satisfactory drainage was possible using the conventional or hybrid system when the two systems were designed to have outflow not exceeding the pre-developed flow. The hybrid drainage system requires smaller pipe sizes compared to the conventional system. Also, the size of the detention basin and maximum outflow rate of the hybrid system were smaller than those for the conventionally drained site. The installation cost of the hybrid drainage system was 18% less than that of the conventional drainage system when the objective was to accommodate 10% and 5% AEP storms.

“…SWMM requires detailed information characterizing urban catchments and the underlying storm water drainage infrastructure. The input to the models comprises of various physical and hydrological parameters representing urban catchment 25 . The surface runoff in a sub-catchment is routed fully to enter the junction and transported through the storm sewer conduits to the area outlet, so there is only pipeline runoff flow and no surface runoff routing is considered.…”

Managing storm water under climate uncertainty is a major concern in urban areas throughout the world. There were several floods events recorded in Chennai, a one of the major metropolitan coastal city in India. The flood incidences were repeatedly reported in recent decades. In this study, the existing state of storm water drains are evaluated under current and future climate scenarios in one of the most flood-prone areas of Chennai viz. Velachery zone. The mitigation measures are recommended to increase its resilience against floods. The Intergovernmental Panel on Climate Change (IPCC) CMIP5 models of Representative Concentration Pathways (RCP) 4.5 are used to develop possible future climate change scenarios of the city. The daily rainfall data for the period 1975–2015 obtained from India Meteorological Department are used to find the extremities and to generate Intensity-Duration-Frequency (IDF) curves. The IDF curves are generated for 2, 5, 10, 50, 100 year return period under current and future climate scenarios. The storm drainage network are delineated with Differential Geographic Positioning System (DGPS) survey. The integrated hydraulic and hydrological modelling is carried out to assess the flood carrying capacity of storm drainage under present and future climate scenarios. The vulnerable hotspots are identified and flood mitigation measures are suggested to reduce the flood risk at Velachery.
