Special Issue Information

Dear Colleagues,

Under the pressure of urbanization, the science of urban hydrology has advanced to improve urban water system management for developing/creating more livable cities, in which public safety and health, as well as the environment, are protected. The ultimate goal of urban water management is to mimic the hydrological cycle prior to urbanization. On top of urbanization, climate change, which has been demonstrated to alter the hydrological cycle in all respects, is further introducing challenges to managing urban water systems. To mitigate and adapt to urbanization under a changing climate, our further understanding of key hydrologic components should be expanded including climate change into consideration; thus, effective and efficient measures can be formulated. Furthermore, urban water management aims to improve system resiliency and sustainability given that the principle of stationarity may be invalid under urbanization and climate change. Therefore, this Special Issue will cover a wide range of topics from fundamental urban hydrology to measures for enhancing urban water management under urbanization and climate change. 

The specific topics include, but are not limited to:

  • Rainfall measurement, modeling, and forecasting at a finer resolution in both time and space for variability/change assessment and urban hydrological modeling;
  • Impacts of urbanization and climate change on hydrologic components including evapotranspiration, surface runoff and subsurface flow;
  • Impacts of urbanization and climate change on receiving water bodies with a focus on degradation in water quality (including conventional and emerging pollutants) and ecosystems;
  • Hydrological modeling and forecasting, particularly taking into account the impacts of both urbanization and climate change;
  • Approaches to managing urban stormwater using infiltration-based techniques (e.g., bioretention systems, permeable pavements, green roofs, etc.) and retention-based techniques (e.g., stormwater ponds, wetlands, etc.) and stormwater reuse;
  • Assessment of uncertainty from various sources in hydrological modeling/analysis, especially in a changing climate;
  • Urban water infrastructure design (e.g., stormwater drainage system) in a changing climate and/or urbanization;
  • Non-stationary hydrology.

The Low-Impact Development Demand Index: A New Approach to Identifying Locations for LID
Water 2019, 11(11), 2341; https://doi.org/10.3390/w11112341 - 08 Nov 2019
Abstract

The primary goal of low impact development (LID) is to capture urban stormwater runoff; however, multiple indirect benefits (environmental and socioeconomic benefits) also exist (e.g., improvements to human health and decreased air pollution). Identifying sites with the highest demand or need for LID ensures the maximization of all benefits. This is a spatial decision-making problem that has not been widely addressed in the literature and was the focus of this research. Previous research has focused on finding feasible sites for installing LID, whilst only considering insufficient criteria which represent the benefits of LID (either neglecting the hydrological and hydraulic benefits or indirect benefits). This research considered the hydrological and hydraulic, environmental, and socioeconomic benefits of LID to identify sites with the highest demand for LID. Specifically, a geospatial framework was proposed that uses publicly available data, hydrological-hydraulic principles, and a simple additive weighting (SAW) method within a hierarchical decision-making model. Three indices were developed to determine the LID demand: (1) hydrological-hydraulic index (HHI), (2) socioeconomic index (SEI), and (3) environmental index (ENI). The HHI was developed based on a heuristic model using hydrological-hydraulic principles and validated against the results of a physical model, the Hydrologic Engineering Center-Hydrologic Modeling System model (HEC-HMS). The other two indices were generated using the SAW hierarchical model and then incorporated into the HHI index to generate the LID demand index (LIDDI). The framework was applied to the City of Toronto, yielding results that are validated against historical flooding records. Full article

Metals Leaching in Permeable Asphalt Pavement with Municipal Solid Waste Ash Aggregate

The leaching behaviors of four heavy metals (Zn, Pb, Cu and Cr) from unbounded municipal solid waste incineration-bottom ash aggregate (MSWI-BAA) and permeable asphalt (PA) mixture containing MSWI-BAA were investigated in the laboratory. The horizontal vibration extraction procedure (HVEP) test and a simulated leaching experiment were conducted on MSWI-BAA with three particle sizes, but only the simulated leaching experiment was carried out on a type of PA specimen (PAC-13) with and without these MSWI-BAAs. Leaching data were analyzed to investigate the leaching characteristics, identify the factors affecting leaching and assess the impact on the surrounding environment. Results indicated that the leaching process was comprehensively influenced by contact time, leaching metal species and MSWI-BAA particle size, regardless of MSWI-BAA alone or used in PAC-13 mixture. The leaching concentrations of Cr, Zn and Pb from MSWI-BAA in HVEP testing was strongly related to MSWI-BAA particle size. The use of MSWI-BAA in PAC-13 mixture did not change the basic tendency of heavy metal leaching, but it led to an increase of Cr and Zn in leachate overall. The leachate from the MSWI-BAA and PAC-13 mixture with MSWI-BAA was shown to be safe for irrigation and would have very little negative impact on surrounding surface and underground water quality.
