A Review of Sustainable Urban Drainage Systems Considering the Climate Change and Urbanization Impacts

Abstract

Climate change and urbanization are converging to challenge city drainage infrastructure due to their adverse impacts on precipitation extremes and the environment of urban areas. Sustainable drainage systems have gained growing public interest in recent years, as a result of its positive effects on water quality and quantity issues and additional recreational amenities perceived in the urban landscape. This paper reviews recent progress in sustainable drainage development based on literature across different disciplinary fields. After presenting the key elements and criteria of sustainable drainage design, various devices and examples of sustainable drainage systems are introduced. The state-of-the-art model approaches and decision-aid tools for assessing the sustainable alternatives are discussed and compared. The paper further explores some limitations and difficulties in the application of the innovative solutions and suggests an integrated and trans-disciplinary approach for sustainable drainage design.

A Hydrophysical Analysis of Urban Surface Runoff, Channel Characteristics, and the Incidence of Flood and Erosion Over the Calabar Drainage Area, Nigeria.

“…The negative sign in the coefficients indicates that flow in a lesser depth or higher ground will be less than on a steeper or lower ground. The reason as noted by Zhou (2014) is because the motion between successive water layers is accumulated upward from the bed and outward from the banks. The Chenzy equation confirms this when it states in words that "mean velocity varies directly as the square-root of the slope..."…”

Poluição difusa nas águas pluviais de uma bacia de drenagem urbana

“…Critérios de sustentabilidade da drenagem urbana englobam um novo paradigma, envolvendo várias áreas da engenharia e de ciên-cias urbanas a fim de se considerar a complexidade do meio urbano e suas interações e soluções (ZHOU, 2014).…”

Making the Case for Sustainable Urban Drainage Systems as a Nature-Based Solution to Urban Flooding

“…Instead of focusing on 'end-of-pipe' or 'at the point of the problem' solutions as is the case with many purely 'grey' infrastructure solutions, sustainable urban drainage systems aim to slow down and reduce the quantity of surface water runoff in an area in order to minimize downstream flood risk and reduce the risk of resultant diffuse pollution to urban water bodies (Rose and Lamond 2013;Woods Ballard et al 2015;Zhou 2014). As a nature-based solution, SUDS achieves these aims by utilizing a mix of natural processes 3 and green/grey components 4 to harvest, infiltrate, slow, store, convey and treat runoff onsite; examples include the following (from Woods ):…”

“…However, these drainage infrastructures often no longer have the capacity to keep pace with on-going urbanisation and the increasing rate of storm water due to climate change and soil sealing, and can lead to increased run-off and a higher risk of urban flooding (EEA 2012;PeralesMomparler et al 2016;Zhou 2014). Additional indirect consequences are an insufficient discharge of excess water to the regional water system, and an increase of pollutants in the water caused by run-off (e.g., oil, organic matter and toxic metals), leading to increases in algal blooms, harm to wildlife and reductions in amenity value (Sharma 2008).…”
