Understanding the causes and impact of flooding

Impact and causes of flood

Flood response

Flooding has always been a source of concern for local authorities and residents alike. It is set to occur after a heavy rainfall and when natural watercourses seem not to have the capacity to carry excess water.  It is also argued that flooding is not always caused by heavy rainfall.  On the other hand, it is believed that the quicker the rainwater gets to a river channel, the higher the possibility of a flood occurrence.

Causes of Flooding

Flooding is caused by an array of factors which could be grouped into these three broad categories: Weather events, poor maintenance and developmental/planning issues.

Weather Events: This is one of the most known causes of flooding. These climatic events come mostly in the form of rainfall, comprising of sustained or extensive rainfall and thunderstorm, over a brief period of time. The other weather related cause of flooding is a heavy flow or high tide mixed with stormy conditions.  Most environmental analysts and enthusiasts are convinced that climate change is also set to increase the risk of flooding in the UK and around the globe.

Poor Maintenance:  Aside rainfall, poor maintenance is also a big cause of flooding. It does comprise of factors like: poor maintenance of watercourses, inadequate drainage networks and broken sewer systems.

Development and Planning Issues:  When appropriate planning and development issues are not taken into consideration, there is a higher risk of flooding. These elements comprise of a poorly designed or flawed flood defence schemes, unsuitable development in flood plains and putting up buildings on land, which hinders rainfall from draining away easily. These building or structures could be in the form of roads and car parks, which are impenetrable to water, hence increasing the danger of flooding from rainwater overflow.

 

Impact of flooding

From late December 2013 to January 2014, the UK experienced one of the wettest periods. There were about 183.8 mm of rain, understood to be about 151% higher than average. The south-east and central southern axis of England, during the months of December 2013 and January 2014, witnessed about a 372.2mm of rain, tagged as the wettest two-month period since 1910.

During this two-month period, it is estimated that about 1135 homes were flooded. This was mitigated or controlled due to the flood protection of about 181, 000 homes. Accountancy firm PWC, believe that the clear-up cost for the above flood incident could go north of a £1bn.  Overall, it is believed that the management of flood risk cost the UK government about £2.2bn annually. It is also important to note that about 5.2m properties in England are at risk of flooding from rivers (or seas) and about 1 million are vulnerable to surface-water flooding.

The efforts to manage and provide quick response during flooding is massive. We understand that our homes are embodiment of rich family memories passed from generations and business premises (or shops) are source of livelihood.

We also understand how emotionally important these homes, business premises and public infrastructures are. That’s why at Hydro cleansing, we charge our flood-response division to provide flood response services like removal/disposal of flood water, 24/7 flood defences and professional flood clean-up. We are available 24/7 and have our team readily available to heed your emergency flood related calls. Please use our emergency number: 0208 689 3339.
