Cities have suffered from long-time waterlogging problems. A review of English and Chinese literature on “urban waterlogging” can help analyze the research progress and further explore methods and approaches to alleviate such problems in Chinese cities. By examining the literature from the Web of Science Core Collection database and CNKI database with CiteSpace, a Mapping Knowledge Domains tool, this paper aims to scientifically review the disciplinary structure, major research interests, and research hotspots of the issues of urban waterlogging. Through data analyses, it concludes that: 1) urban waterlogging is a hot topic that has been studied in a great number of subjects, with interdisciplinary studies and a continuous growth in Urban and Rural Planning, Geography, Landscape Architecture, etc. in recent years; 2) the research on waterlogging in representative subjects varies; 3) English and Chinese literature explores stormwater management and control measures from the perspectives of planning concepts, infrastructure, drainage systems, spatial regulation, management methods, and micromeasures; 4) research hotspots cover the concepts and measures of waterlogging control, hydrological processes and patterns, causes of waterlogging, and risk assessment and management; 5) the existing research mainly focuses on micro scales, and there is an absence of studies on ideal spatial patterns and planning approaches at macro and medium scales, or on the correlation between urban hydrological processes and waterlogging formation mechanisms with spatial deployment of stormwater regulation approaches. Finally, according to existing research limitations, the paper proposes that: 1) future theoretical studies should explore the backgrounds, objectives, and application scenarios of various waterlogging control approaches; 2) studies are expected to explore spatial patterns and planning approaches at macro and medium scales; and 3) scholars should expand the territory of research by integrating with Hydrology.
