INTRODUCTION

Background to the Study

Flooding has been identified as a significant issue affecting road transport infrastructure in Port Harcourt Metropolis, Nigeria. According to a study by Nwilo and Badejo (2006), the city’s topography, coupled with poor drainage systems, has led to recurrent flooding, causing severe damage to the road infrastructure. The study further highlights that the impact of these floods on the road transport infrastructure has led to increased traffic congestion, road degradation, and in some cases, complete road failure.

A more recent study by Eze and Efiong (2017) corroborates these findings, emphasizing that the impact of flooding on road transport infrastructure in Port Harcourt Metropolis is a growing concern. The study found that during the rainy season, many roads become impassable due to flooding, leading to significant disruptions in the transport network. This not only affects the movement of people and goods but also has a negative impact on the local economy.

The impact of flooding on road transport infrastructure is not limited to physical damage. According to a study by Okoye and Ezezika (2013), flooding also has significant socio-economic implications. The study found that flooding often leads to increased travel times, higher vehicle operating costs, and reduced accessibility to certain areas of the city. This, in turn, affects the overall productivity of the city and the quality of life of its residents.

However, it’s not all doom and gloom. A study by Achi et al. (2019) suggests that there are potential solutions to mitigate the impact of flooding on road transport infrastructure in Port Harcourt Metropolis. The study recommends the implementation of proper urban planning and drainage systems, as well as the use of flood-resistant materials in road construction. The study also suggests that regular maintenance of existing road infrastructure can help reduce the impact of flooding.

Despite these potential solutions, a study by Ojeh et al. (2020) argues that there is a lack of political will and funding to implement these measures. The study suggests that until these issues are addressed, the impact of flooding on road transport infrastructure in Port Harcourt Metropolis will continue to be a significant problem.

The impact of flooding on road transport infrastructure in Port Harcourt Metropolis is a multifaceted issue that requires a comprehensive approach. While there are potential solutions, their implementation is hindered by various challenges. Therefore, further research is needed to explore innovative and cost-effective strategies to mitigate the impact of flooding on road transport infrastructure in this region.

Statement of the Problem

Flooding in Port Harcourt Metropolis has been a persistent problem, causing severe damage to the road transport infrastructure. The city’s road network, which is vital for the movement of goods and people, has been severely affected by recurrent flooding (Njoku, 2017). The problem is exacerbated by the city’s topography and the lack of effective drainage systems, which leads to water accumulation on the roads during heavy rainfall.

The impact of flooding on the road transport infrastructure is multifaceted. It not only causes physical damage to the roads but also disrupts the normal flow of traffic, leading to increased travel times and costs (Ogbonna, 2018). The frequent road closures due to flooding also affect the economic activities in the city, as businesses and industries rely heavily on the road network for their operations.

The flooding problem in Port Harcourt Metropolis is further compounded by the city’s rapid urbanization. The increased construction activities have led to the loss of natural drainage channels, thereby increasing the vulnerability of the road infrastructure to flooding (Eze, 2019). The lack of proper urban planning and enforcement of building codes has also contributed to the problem.

The impact of flooding on the road transport infrastructure in Port Harcourt Metropolis is not only a local issue but also has national implications. The city is a major economic hub in Nigeria, and any disruption in its road network can have ripple effects on the country’s economy (Njoku, 2017). Therefore, there is an urgent need to address this problem.

Despite the severity of the problem, there is a lack of comprehensive studies on the impact of flooding on the road transport infrastructure in Port Harcourt Metropolis. Most of the existing studies focus on the general impact of flooding in the city, without specifically addressing its effect on the road infrastructure (Ogbonna, 2018). This gap in the literature underscores the need for more focused research on this issue.

The impact of flooding on the road transport infrastructure in Port Harcourt Metropolis is a significant problem that requires urgent attention. There is a need for more research to understand the extent of the problem and to develop effective solutions. The findings of such research can provide valuable insights for policymakers and urban planners in their efforts to mitigate the impact of flooding on the city’s road infrastructure.

Significance of the Study

The significance of studying the impact of flooding on road transport infrastructure in Port Harcourt Metropolis is multi-faceted. Firstly, it provides a comprehensive understanding of the extent to which flooding affects the city’s transport infrastructure. This includes the damage to roads, bridges, and other transport facilities, which can lead to disruptions in the movement of people and goods. The study also helps to quantify the economic costs associated with these disruptions, which can be substantial given the city’s role as a major economic hub in Nigeria.

Secondly, the study can help to identify the most vulnerable areas and infrastructure within the city. This is crucial for prioritizing interventions and allocating resources effectively. For instance, areas that are frequently flooded and have critical transport infrastructure may require more attention and investment. This can also guide the design and implementation of infrastructure projects, ensuring that they are resilient to flooding.

Thirdly, the study can contribute to the development of strategies and policies aimed at mitigating the impact of flooding on the city’s transport infrastructure. This could include measures such as improving drainage systems, constructing flood barriers, and implementing land use policies that discourage development in flood-prone areas. These strategies can help to reduce the frequency and severity of flooding, thereby protecting the city’s transport infrastructure.

Fourthly, the study can provide valuable insights for other cities facing similar challenges.
