  • Automatic, semi-automatic and manual validation of urban drainage data

    Advances in sensor technology and the possibility of automated long distance data transmission have made continuous measurements the preferable way of monitoring urban drainage processes. Usually, the collected data have to be processed by an expert in order to detect and mark the wrong data, remove them and replace them with interpolated data. In general, the first step in detecting the wrong, ...

  • Urban drainage system planning and design – challenges with climate change and urbanization: a review

    Urban drainage systems are in general failing in their functions mainly due to non-stationary climate and rapid urbanization. As these systems are becoming less efficient, issues such as sewer overflows and increase in urban flooding leading to surge in pollutant loads to receiving water bodies are becoming pervasive rapidly. A comprehensive investigation is required to understand these factors ...

  • Urban-Water Harmony model to evaluate the urban water management

    Water resources in many urban areas are under enormous stress due to large-scale urban expansion and population explosion. The decision-makers are often faced with the dilemma of either maintaining high economic growth or protecting water resources and the environment. Simple criteria of water supply and drainage do not reflect the requirement of integrated urban water management. The ...

  • A review of the adaptation and mitigation of global climate change using sustainable drainage in cities

    Sustainable drainage (SUDS) is well known for its equal emphasis on water quality, water quantity, amenity and biodiversity. What is now beginning to be realised is that this approach can also help mitigate the impacts of global climate change (GCC) and provide assistance to city dwellers in adapting to the changes which have already occurred. By using case studies from around the world, this ...

  • Urban pluvial flooding in Jakarta: applying state-of-the-art technology in a data scarce environment

    Available data relating to major pluvial flooding events in Jakarta, Indonesia were used to investigate the suitability of two different levels of sophistication in urban modelling tools for modelling these events. InfoWorks CS v9.0 was employed to build 1D and 1D/2D models of a 541 ha area of inner city Ciliwung River catchment which has a history of being particularly badly affected by flooding ...

  • Integrating GIS and Hydraulic Modelling in Urban and Rural Applications

    Overview In the UK, numerical Hydraulic Modelling of the urban environment, water networks and rivers plays a vital role in providing the UK Water Industry with solutions for protecting the environment, meeting UK Government and European Regulations, meeting OPEX and CAPEX business targets, and improving the efficiency of Water Companies in managing their assets. Similarly, the UK water ...

  • Urban environment — SOER 2010 thematic assessment

    Urban areas and quality of life For the three-quarters of Europe’s population that lives in cities and towns, a good urban environment is a precondition for a good quality of life. It seems, in part, that over the last decade, attitudes to living in cities have been changing. People are no longer moving away from cities (or have returned to them), residential sprawl has slowed and, in a ...

  • Enlightenment from ancient Chinese urban and rural stormwater management practices

    Hundreds of years ago, the ancient Chinese implemented several outstanding projects to cope with the changing climate and violent floods. Some of these projects are still in use today. These projects evolved from the experience and knowledge accumulated through the long coexistence of people with nature. The concepts behind these ancient stormwater management practices, such as low-impact ...

  • Major urban water and wastewater systems in Minoan Crete, Greece

    During the Minoan era a number of remarkable developments occurred on the Greek island of Crete which have been widely recognized. However, one of the salient characteristics was the architectural and hydraulic function of its water supply, sewerage, and drainage systems in the Minoan palaces, cities, and other settlements. It might be inferred, therefore, that Minoan master craftsmen in Bronze ...

  • Protocols for Evaluating the Effects of Land-use Patterns and Runoff Management on Urban Streams

    ABSTRACTThe design of urban runoff management facilities generally includes peak shaving for flood control, and best management practices (BMPs) for removing pollutants from the runoff. A number of scientists have concluded that the combination of these two control practices, which were developed independently of one another, is not sufficient to protect aquatic ecosystems. But these conclusions ...

  • Impediments to the adoption of alternative sewerage in South African urban informal settlements

    In recent decades South Africa has witnessed a substantial growth in its urban population. This growth has been accompanied by the mushrooming of informal settlements (shantytowns) flanking more formal development. The lack of adequate urban drainage in many of these informal settlements has resulted in extremely polluted environments which add to the disease burden of the poor people who live ...

  • Using Permeable Eco-Paving to Achieve Improved Water Quality for Urban Pavements

    This paper describes the planning, design and construction of a permeable pavement as a practical demonstration of the benefits of eco-paving in Australian environmental management. The paper addresses the use of permeable pavements as part of a Water Sensitive Urban Design that allows infiltration of stormwater, reduction of pollutants and slow reticulation of the stormwater to an ecologically ...

  • Multi-objective optimisation of cost–benefit of urban flood management using a 1D2D coupled model

    This paper presents a multi-objective optimisation (MOO) tool for urban drainage management that is based on a 1D2D coupled model of SWMM5 (1D sub-surface flow model) and BreZo (2D surface flow model). This coupled model is linked with NSGA-II, which is an Evolutionary Algorithm-based optimiser. Previously the combination of a surface/sub-surface flow model and evolutionary optimisation has been ...

  • Innovative technologies for management of stormwater and combined sewer flows

    Stormwater flows have historically been considered as harmless. Studies have shown that these flows cannot be dismissed as easily. Chebbo (1992), Marsalek et al.,(1997) and others have shown that stormwater is a source of diffuse pollution with a high source of total suspended solids (TSS), adsorbed hydrocarbons (HC) and nutrient loads (N, P, etc..). All these factors influence the quality of the ...

  • Applying multi-criteria decision analysis to select WSUD and LID technologies

    Water Sensitive Urban Design (WSUD) and Low Impact Development (LID) principles were investigated in Dhaka's drainage network using ‘Regime in Balance’ strategy for Average Recurrence Interval (ARI), Y = 100 years. Three feasible alternatives, such as, leaky-well, soak-away and infiltration trench were identified and designed to improve Dhaka's present ...

  • A brief history of water supply and wastewater management in ancient Greece

    The evolution of urban water management in ancient Greece begins in Crete during the Middle Bronze and the beginning of the Late Bronze Ages (ca. 2000–1500 B.C.) when many remarkable developments occurred in several stages as Minoan civilization flourished on the island. One of its salient characteristics was the architectural and hydraulic function of its water supply and sewerage systems in the ...
