The study examines Permeable Interlocking Concrete Pavers (PICP) systems in urban and suburban areas facing intensified stormwater challenges due to climate change and evolving land use patterns. It investigates various factors affecting PICP performance, including soil, topography, vegetation, and rainfall intensity, using advanced modeling techniques. The study’s methodology integrates Personal Computer Storm Water Management Model (PCSWMM) model and Python scripting, utilizing historical and projected data to guide resilient PICP designs. Climate projections from 2030 to 2080 show a significant increase in stormwater runoff due to urbanization, emphasizing flood risk concerns. The findings indicated a substantial 43 % increase in runoff for the City of Renton-Cedar watershed in Washington from 2030 to 2069. Without PICP implementation, a notable 20.3 % surge in total runoff volume is anticipated. This highlights the crucial role of PICP and sustainable urban planning in mitigating urbanization’s impact on hydrology. With PICP implementation, the results show that the total runoff may reduce to a range within 24 %–75 % for the three land use scenarios (15 %, 25 % and 35 %). The results also exhibited a significant (P < 0.05) and strong (R2 > 0.8) direct relationship between clogging and PICP systems. Overall, the research underscores PICP systems’ effectiveness in managing stormwater, emphasizing their importance in diverse urban settings, and advocating for green infrastructure adoption to enhance urban resilience amidst changing environmental dynamics.

评估透水互锁混凝土摊铺机 （PICP） 在气候变化和土地使用情景下管理雨水径流的有效性


该研究检查了城市和郊区的透水互锁混凝土摊铺机 （PICP） 系统，由于气候变化和不断变化的土地利用模式，雨水挑战加剧。它使用先进的建模技术研究了影响 PICP 性能的各种因素，包括土壤、地形、植被和降雨强度。该研究的方法集成了个人计算机雨水管理模型 （PCSWMM） 模型和 Python 脚本，利用历史和预测数据来指导弹性 PICP 设计。2030 年至 2080 年的气候预测显示，由于城市化，雨水径流显着增加，这凸显了洪水风险的担忧。研究结果表明，从 2030 年到 2069 年，华盛顿州伦顿-雪松市流域的径流大幅增加了 43%。如果不实施 PICP，预计总径流量将显着增加 20.3%。这凸显了 PICP 和可持续城市规划在减轻城市化对水文影响方面的关键作用。随着 PICP 的实施，结果表明，对于三种土地利用情景（15 %、25 % 和 35 %），总径流可能会减少到 24 %–75 % 之间的范围。结果还表明，堵塞与 PICP 系统之间存在显著 （P < 0.05） 和强 （R2 > 0.8） 的直接关系。总体而言，该研究强调了 PICP 系统在管理雨水方面的有效性，强调了它们在不同城市环境中的重要性，并倡导采用绿色基础设施，以增强城市在不断变化的环境动态中的韧性。
