Introduction

Flooding has always been a problem in times past caused by different reasons and has always occurred over a long period of human history. Different types of flood can be caused by coastal flooding – storms, high tides, sea-level rise, and insufficient protection; river/fluvial floods – snowmelt or high precipitation in catchment areas which tends to lead to flash floods or riverine floods; pluvial floods – this is caused by extreme rainfall and failing drainage systems or compound floods from cyclonic monsoon which then enhances intensive rainstorms and surges together; or rapid snowmelt (Kundzewicz, 1999).

Flood risk has always posed a significant threat to communities, ecosystems, and economies, especially in the context of climate change. The United Kingdom (UK) and the European Commission (EC) have now implemented policies and legislation to address these concerns. This analysis critically evaluates the potential effectiveness of UK and EC policies in mitigating flood risk and adapting to climate change, taking into account the interests and concerns of various stakeholders.

Causes of Flooding

There are different causes of flooding that need tackling, these types of flooding include;

  1. River Flooding: This happens when the watercourse cannot cope with the runoff it from the land surrounding it. An example can be when there is heavy rainfall on an already waterlogged catchment.
  2. Sewer Flooding: This happens mostly when the sewers are blocked with debris and there is no proper flow or when there is an overflow of runoff due to heavy rainfall. Rivers can also be polluted by the sewer overflow.
  3. Coastal Flooding: This is when there is a combination of both high tides and stormy conditions. A tidal surge will occur when there is a low atmospheric pressure which then coincides with a high tide. This then goes on to cause serious flooding.
  4. Surface Water Flooding: This occurs when the runoff overwhelms the drainage capacity and cannot handle the pressure due to the heavy rainfall.
  5. Ground Water Flooding: This happens when the groundwater surpasses its level and then overflows back onto the surface land. This is mostly caused by aquifers, which means when the soil is underlain by permeable rocks.

 

United Kingdom (UK) and European Commission (EC) Policies on Flood Risk: A Comparative Analysis

UK Legislation and Policies:

The UK has a comprehensive framework for managing flood risk, including the Flood and Water Management Act 2010 and the National Flood and Coastal Erosion Risk Management Strategy for England. These policies emphasize a holistic approach, incorporating sustainable urban planning, community engagement, and investment in infrastructure. The establishment of the Environment Agency and regional Flood and Coastal Committees illustrates the commitment to a coordinated response.

The UK legislation and Policies have been very effective so far as they have devised two main approaches to tackle the flooding in the UK, however, they also have a disadvantage to it. These two main approaches are;

  1. Integrated Approach:
    • Strength: The UK’s integrated approach, addressing both mitigation and adaptation, is a positive step. It acknowledges the interconnectedness of land use planning, infrastructure development, and climate resilience.
    • Weakness: Implementation gaps persist due to challenges in coordination between different agencies and levels of government, leading to fragmented efforts.
  2. Community Engagement:
    • Strength: Involving communities in flood risk management enhances local resilience and fosters a sense of ownership. Community Flood Resilience Groups exemplify a bottom-up approach.
    • Weakness: Socioeconomic disparities may hinder community engagement in vulnerable areas, requiring tailored strategies to address diverse needs.
