Analysing urban floods and combined sewer overflows in a changing climate
Climate change is expected to lead to an increased frequency and intensity of extreme precipitation events. For urban drainage, the primary adverse effects are more frequent and severe sewer overloading and flooding in urban areas, and higher discharges through combined sewer overflows (CSO). For assessing the possible effects of climate change, urban drainage models are run with ...

Impact of urban WWTP and CSO fluxes on river peak flow extremes under current and future climate conditions
The impact of urban water fluxes on the river system outflow of the Grote Nete catchment (Belgium) was studied. First the impact of the Waste Water Treatment Plant (WWTP) and the Combined Sewer Overflow (CSO) outflows on the river system for the current climatic conditions was determined by simulating the urban fluxes as point sources in a detailed, hydrodynamic river model. Comparison was made ...

Ecological design for climate mitigation in contemporary urban living
Evaporation is the most important hydrological function on Earth because it provides rain. As deforestation and urbanisation reduce plant cover and evapotranspiration, ever more short-wave solar radiation is converted to long-wave thermal emissions and sensible heat. Higher surface temperatures set up heat island effects, contributing to local, and ultimately, global climate change. Rainwater ...

Water security and sustainability in urban India
The rapid growth of population combined with rising levels of consumption and pollution has increased water insecurity in urban India. The depleting water sources on the one hand, higher financial and technological costs to refine and transport water from far off sources on the other, leave limited possibilities to augment the water supply in the near future. Climate change may further adversely ...
