Special Issue Information

Dear Colleagues,

In recent years, climate change and urbanization have led to significant pluvial flood events in a range of countries worldwide. This has prompted the development and implementation of effective and innovative approaches for designing and managing urban stormwater systems. The gradual urbanization process is causing an increase in impervious surfaces, resulting in higher surface runoff and velocity. This, in turn, reduces concentration times of watersheds, leading to increased soil erosion and deteriorating water quality due to intensive contamination.

Low-impact development (LID) practices for controlling urban runoff can be considered an effective approach to addressing this concern. These practices aim to enhance urban resilience against flooding risks and ensure environmental interventions that address the changing climate and land use patterns. This Special Issue invites research contributions that present groundbreaking advancements in both experimental and modeling research on LIDs. We encourage the submission of articles on various LID-related topics, including decision support systems (DDS) for the optimal design of LIDs in urban sub catchments, case studies evaluating the effectiveness of low-impact development strategies, simulation of LID practices, and the calibration of parameters for modeling LID practices.

Low-Impact Developments (LIDs), like green roofs and bioretention cells, are vital for managing stormwater and reducing pollution. Amidst climate change, assessing both current and future LID systems is crucial. This study utilizes variably saturated flow modeling with the HYDRUS software (version 4.17) to analyze ten locations in Ontario, Canada, focusing on Toronto. Historical and projected climate data are used in flow modeling to assess long-term impacts. Future predicted storms, representing extreme precipitation events, derived from a regional climate model, were also used in the flow modeling. This enabled a comprehensive evaluation of LID performance under an evolving climate. A robust methodology is developed to analyze LID designs, exploring parameters like water inflow volumes, peak intensity, time delays, runoff dynamics, and ponding patterns. The findings indicate potential declines in LID performance attributed to rising water volumes, resulting in notable changes in infiltration for green roofs (100%) and bioretention facilities (50%) compared to historical conditions. Future climate predicted storms indicate reduced peak reductions and shorter time delays for green roofs, posing risks of flooding and erosion. Anticipated extreme precipitation is projected to increase ponding depths in bioretention facilities, resulting in untreated stormwater overflow and prolonged ponding times exceeding baseline conditions by up to 13 h at numerous Ontario locations.
