The purpose of this study is to evaluate the relationship between urban infrastructure and flood disaster in Gombe metropolis, Nigeria. In this research work, the survey research design was used to obtain data from the field. Stratified sampling technique was adopted in determining the study sample which consisted of 250 households (i.e. 13% of the population, made up of 1,923 households). 250 questionnaires were administered on household heads in the study area; however, only 237 questionnaires were retrieved and used for analysis. Spearman’s rank correlation and multiple linear regression analysis were used to examine the relationships between the criterion variable (flood disaster) and the predictor variables (urban infrastructure). The study showed that inadequacy of appropriate urban infrastructure is the major factor responsible for flood disaster in Gombe metropolis [R = 0.792, P = 0.000<0.01(2-tailed)]. It was recommended among others, that there should be improvement on the maintenance of available drainage infrastructure in the metropolis and the integration of solid waste management to prevent over flowing of flood as a result of blockage of drains. Government and all other stakeholders should expedite the provision of appropriate urban infrastructure in the metropolis.
本研究的目的是评估城市基础设施与洪水灾害的关系，在贡贝大都市，尼日利亚。在本研究工作中，采用调查研究设计，从现场获取数据。在确定研究样本时采用分层抽样技术，该研究样本由250户(即13%的人口，由1,923户组成)组成。对研究地区的户主发放了250份问卷;然而，只有237份问卷被收回并用于分析。采用Spearman秩相关分析和多元线性回归分析检验了标准变量(洪涝灾害)与预测变量(城市基础设施)之间的关系。研究表明，适宜的城市基础设施不足是贡贝大都市洪涝灾害的主要原因[R = 0.792, P = 0.000<0.01(双尾)]。除其他外，还建议改善对大都市现有排水基础设施的维护，并将固体废物管理一体化，以防止由于排水沟堵塞而造成洪水泛滥。政府和所有其他利益相关者应加快在大都市提供适当的城市基础设施。
