基于MIKE FLOOD耦合模型的刚果(布)某工业厂区排水能力评估

Assessment of Drainage Capacity for an Industrial Plant Area in Congo (Brazzaville) Based on the MIKE FLOOD Coupled Model

摘要: 为有效应对非洲中西部刚果(布)沿海地区新建厂区的暴雨洪涝灾害，本文基于MIKE FLOOD平台，将MIKE11和MIKE21模型耦合，构建了厂区内涝模型。选取新建的某工业厂区进行模拟，结果表明遭遇10年和20年一遇暴雨下的地面积水深度主要集中在0.07~0.18 m，水深在空间分布上大体呈一致状态，积水时间主要集中在5.95~6.0 h，对应风险等级为轻微和低风险。该研究成果可为厂区排水设施规模、防涝措施等提供技术参考，一定程度减少受灾损失。

Abstract: To mitigate storm-induced flood risks in the newly constructed industrial zone along the coastal area of Congo (Brazzaville) in Central-West Africa, an integrated urban inundation model was established using the MIKE FLOOD platform, which dynamically couples the 1D hydrodynamic MIKE11 and 2D overland flow MIKE21 models. Simulations focused on a representative industrial plant within the zone, which revealed that under 10- and 20-year return period storm events, surface ponding depths ranged from 0.07 to 0.18 m, with spatially homogeneous distribution patterns. Inundation durations were confined to 5.95~6.0 hours, corresponding to slight-to-low risk classifications. These findings offer actionable insights for optimizing drainage infrastructure design and implementing targeted flood resilience strategies, demonstrating practical potential to minimize flood-related economic disruptions in similar tropical coastal industrial developments.
