Special Issue Information

Dear Colleagues,

The majority of the world’s populations currently live in urban areas, and existing or new urban centers will continue to grow in size and economic importance. In particular, urban water infrastructures (e.g., drainage and water supply systems) have been constructed at a large scale in cities all over the world. These infrastructures have reduced the vulnerability of these cities in general but at the same time could make them more vulnerable to the increasing climate variability and extremes, partly due to the lack of consideration as to what might occur when the design criteria or the current operation and management strategies are no longer suitable in the context of a changing climate. Consequently, design professionals and urban water managers need to start accounting for these effects in the design, planning, and management of urban infrastructures in order to minimize the risks of failures of these systems and to increase the resilience of the urban environment. Research on the development of suitable approaches to limiting climate change and adapting to its impacts on urban infrastructures, especially urban water utilities, is therefore highly critical.

The key challenge would be to predict accurately the impacts of climate change on urban hydrologic processes (such as temperature, rainfall, and runoff) at the scale of the urban watershed in order to develop suitable design procedures and appropriate strategies for operation of urban water systems taking into account the legacy of existing networks and their maintenance. Another key issue is: how do we assess adaptation measures and identify the one that could best be used to develop a robust and sustainable method for the management of these systems in consideration of the future variability of urban hydrologic processes as well as the changing social and economic constraints?

The main purpose of this Special Issue is to present a collection of original research papers and review articles on the state of the art, recent advances, and emerging challenges in the design, planning, and management of urban water infrastructures in the context of climate variability and climate change. We particularly solicit papers that provide a description of the evolution of perspectives linked to new theoretical developments, advanced mathematical methods for the modeling of urban hydrologic processes over a wide range of spatial and temporal scales, advanced real-time operation and control of urban water systems, and smart water measurement and monitoring networks. In addition, we welcome papers focused on novel concepts and innovative approaches and tools.

The annual average rainfall in Busan area is increasing, causing frequent flooding of Busan’s Suyeong and Oncheon rivers. Due to the increase in urbanized areas and climate change, it is difficult to reduce flood damage. Therefore, new methods are needed to reduce urban inundation. This study models the effects of three flood reduction methods involving Oncheon River, Suyeong River, and the Hoedong Dam, which is situated on the Suyeong. Using EPA-SWMM, a virtual model of the dam and the rivers was created, then modified with changes to the dam’s height, the installation of a floodgate on the dam, and the creation of an underground waterway to carry excess flow from the Oncheon to the Hoedong Dam. The results of this study show that increasing the height of the dam by 3 m, 4 m, or 6 m led to a 27%, 37%, and 48% reduction in flooding, respectively, on the Suyeong River. It was also found that installing a floodgate of 10 × 4 m, 15 × 4 m, or 20 × 4 min the dam would result in a flood reduction of 2.7% and 2.9%, respectively. Furthermore, the construction of the underground waterway could lead to an expected 25% flood reduction in the Oncheon River. Measures such as these offer the potential to protect the lives and property of citizens in densely populated urban areas and develop sustainable cities and communities. Therefore, the modifications to the dam and the underground waterway proposed in this study are considered to be useful. Full article
