Background

The town of Hawick has a history of damaging floods from both the River Teviot (which runs through the length of the town) and the Slitrig Water (which enters the Teviot by the town centre). The following events are noted:

  • In October 2005 flooding of the River Teviot caused extensive inundation of the urban areas adjacent the River Teviot through the town. This was a 1 in 50 year flood event: it affected hundreds of properties and caused millions of pounds of damage.
  • Risk workshop held comprising members of the project team and other service departments within the council
  • In January 2005 a similar but less severe event occurred. This was an approximate 1 in 25 year flood event.
  • Continuous flow records for the River Teviot exist since January 1961 and confirm the town has also experienced flood events greater than 1 in 10 years in November 2009, October 2002, February 1997, and October 1977.
  • Major flood events on the Slitrig Water were recorded in 1767 and 1846, however there was limited flooding in 1997 amongst other events.

Flow Record extracted from the SEPA Gauging Station

There is an automatic flow gauging station located at the bottom of the town on the River Teviot by Haughhead. This has captured the flow in the river on a continual basis since 1961 and has allowed the Project Team to undertake an analysis of the number of times that the River Teviot has spilled over its banks during that time.

The Project Team designed and displayed an exhibition board on historical flooding at the Public Exhibition No. 1. (more details)

The Project Team will provide further detail of historical flooding to the town of Hawick during subsequent updates of this website.

The Flood Risk to Hawick

One of the first activities undertaken by the Project Team was to update the existing flood model of the River Teviot. The revised model is a sophisticated tool through which the team are able to understand the flood risk to Hawick and consider the implications of each potential flood protection option.

The model is an ISIS 1D /2D linked hydrodynamic model of the River Teviot and stretches from Langlands Bridge to Hornshole Bridge. This model has allowed the team to produce detailed flood maps for each key flood event and also to highlight the properties that are at flood risk.

The model has identified over 1,000 properties that at risk of flooding from the 1 in 200 plus climate change flood event. This is a major flood event and is larger that the event of October 2005. It is the Council’s objective to advance a Scheme that will significantly reduce the flood risk to these properties and thereby improve the quality of life for hundreds of Hawick’s residents, businesses and employees.
