Special Issue Information
Dear Colleagues,
The conventional design of drainage systems has been developed focusing on the quick and efficient conveyance of water from where rainfall occurs, in order to mitigate flood risks. However, these approaches of drainage system design increase unexpected flood risks, especially in downstream areas. These efficient systems are also more sensitive to spatio-temporal rainfall variations, for producing more severe flow peaks. Pumping stations in urban areas often fail with exceeding the rainfall amount, and do not even meet their original design capacities. This century has been witnessed unprecedented hydrologic extremes, such as floods and droughts on every corner of the Earth. Urbanization is inevitable with the increasing population and with the increasing impervious cover. These changing environments raise us a new, but fundamental question of our sustainability, in even the near future. Will our infrastructures or our systems, which are focused mainly on efficiency, but that are becoming more and more vulnerable, remain functional and sustainable in the near future?
Engineers and policy makers are to seek alternative and sustainable solutions that are environmentally friendly, that are functional as conventional solutions, even under changing environments. The approach is often generally called the green infrastructure (GI), with many other expressions, such as lower impact development (LID), best management practice (BMPs), sustainable drainage (SuDs), and so forth. However, the quantitative evaluations of the GI are quite limited, because of difficulties in the validation and observation of flow quantities in urban environments.
This Special Issue aims to contribute to the quantitative evaluation of sustainable drainage systems, to implement them more strategically under a changing environment. The evaluation of a sustainable drainage system includes various aspects of the values in it, such as the engineering, economic, environmental, aesthetic, and social value that it creates.

Manuscript Submission Information
Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.
Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Sustainability is an international peer-reviewed open access semimonthly journal published by MDPI.
Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2400 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.
