Abstract

Urban flooding has become a critical challenge in Nigerian cities, driven by inadequate drainage infrastructure, rapid urbanization, and weak institutional frameworks. This study assessed drainage infrastructure and its role in urban flood mitigation in Damaturu, Yobe State. The objectives were to evaluate the condition and capacity of existing drainage systems, examine the effects of human activities and institutional practices on their effectiveness, and propose sustainable strategies for reducing flood risks. A mixed-methods approach was employed, involving household surveys of 200 respondents, key informant interviews, direct field observations, and GIS mapping. Descriptive and thematic analyses were applied. Findings revealed that 60% of respondents rated drainage systems as poor, while 45% of channels were observed to be physically blocked. Indiscriminate waste disposal (68%) and encroachment on drainage paths (42%) emerged as major human-induced challenges. Institutional weaknesses, including inadequate funding (75%) and poor enforcement of regulations, further limited drainage effectiveness. Flooding impacts included property damage (65%), loss of income (58%), and health risks such as malaria and cholera (72%). The study concludes that drainage inadequacy, human behavior, and weak governance are central to Damaturu’s flood vulnerability. It recommends upgrading drainage infrastructure, adopting Sustainable Urban Drainage Systems (SUDS), and improving waste management and policy enforcement.
