Parameter estimation of urban drainage models
Urbanisation is one of the key factors that contributes to urban flooding, which has caused major destruction to the environment and the human race. In particular, the increase in population and building density influence the change in hydrological characteristics in urban areas. Conversion of …

The effect of rainstorm movement on urban drainage network runoff hydrographs
… and storm sizes. The configuration of the drainage network is simulated with Gibbs’ model. The peak response is investigated with different rainstorm conditions and network configurations. The results show that the effect of the direction and speed of the rainstorm movement significantly …

Behaviour and effectiveness of in-ground sustainable urban drainage systems in Scotland
… drains are the most common types o f sustainable urban drainage systems (SUDS) in Scotland. Despite their extensive use there has been only limited examination of their performance, with the general expectation that failure through lack of maintenance and poor detailing design would necessitate …

Urban drainage modeling and evolutionary multiobjective optimization for combined sewer overflows prediction and control
As urbanization rapidly expands and climate change appears to contribute to more extreme rainfall events, the stress on urban wastewater systems increases. In particular, urban flooding and river water quality degradation due to combined sewer over flows (CSOs) are prevailing problems in urban …

The social dimension of stormwater management practices including sustainable urban drainage systems and river management options
… research programme was relevant to urban planning and in particular to the design of stormwater management schemes that are more environmentally and socially acceptable. It examined social and perception issues relating to stormwater management techniques within residential areas, …

The effectiveness of certain sustainable urban drainage systems in controlling flooding and pollution from urban runoff
… thesis addressed the performance of Sustainable Urban Drainage Systems (SUDS) at three sites in Scotland - a porous paved car park and two swales. It is the first research to provide results for such systems in the UK and also the first direct comparison between SUDS and traditional systems in …

The critical success factors for landscape management of operations on sustainable urban drainage system (SuDS) projects
Population explosion and urbanization are the most significant reasons for increasing pressure on the earth's natural resources, particularly water. Historically, water services have been supplied and discharged through a network of piped infrastructure and hardened surfaces with the main …

How spatial planning can enable pathways to the implementation of sustainable urban drainage systems in the city bowl, Cape Town
… trend of population growth has led to a rapid urbanisation, resulting in unprecedented land cover change. The incarnation of accompanying developed has typified impermeable surfaces. These surfaces have disconnected the stormwater component of the natural hydrological cycle, disregarding it as …

The role of knowledge and institutional challenges to the adoption of sustainable urban drainage in Saudi Arabia: implications for sustainable environmental development
Urban drainage in Saudi Arabia is an increasingly challenging issue due to factors such as climate change and rapid urban expansion. The existing infrastructure, based on traditional drainage systems, is not always able to cope with the increased precipitation, sometimes leading to rainwater runoff …

Sustainable urban drainage and IoT monitoring for urban flood mitigation in a changing climate [Sistemi di drenaggio urbano sostenibile e IoT per la mitigazione delle inondazioni urbane in un contesto di cambiamento climatico]
L'urbanizzazione, insieme al riscaldamento globale e alla pianificazione urbana inadeguata, sta alterando il ciclo idrologico, intensificando i rischi naturali e, in particolare, le inondazioni in ambito urbano. Una gestione efficace del rischio di inondazione richiede sia misure di mitigazione …

Analysing peak flow attenuation in an urban wetland
Worldwide urbanization and climate change are influential in changing precipitation patterns and hydrological flow resulting in event driven urban flooding. The approach to flood protection has recently shifted from engineered and technical solutions to more sustainable and integrated solutions, by …

Development of the simple economic model (SEM) for stormwater management
Sustainable urban Drainage Systems (SuDS) are increasingly being implemented around the world. A common barrier to the wider use of SuDS in South Africa is the uncertainty regarding their total cost. The need for reasonable predictions of life cycle cost is vital, both in terms of ensuring the …

The effects of upstream Natural Flood Management on urban surface drainage performance
… also mitigate surface flood risk in downstream urban areas. By moderating water levels in receiving watercourses, upstream NFM could promote free discharge from urban drainage outfalls and thereby improve local surface drainage performance. A novel modelling methodology has been developed to …

Effect of urban street pattern on drainage.
… storm occurrence, most cities use streets as the drainage route even though their primary function is for the movement of traffic. As a result, the shape of a runoff hydrograph at the outlet of an urban watershed will vary with the pattern of street arrangement within the watershed. The objective …

Modelling of urban stormwater drainage systems using ILSAX
… last few decades, the world has witnessed rapid urbanisation. One of the many complex problems resulting from increased urbanisation is related to management of stormwater from developed areas. If stormwater is not managed properly, it may lead to flooding of urban areas, and deterioration of …
