DIG Update 9 Oct 2024

Hi All,

               In my last mail I mentioned Andrew Morsley, a hydrologist working for the River Thame Conservation Trust (RTCT). He is known to a number of you because he stopped off and spoke with a number of residents in the Warrendene area on the day of the flooding there (23rd September).

RTCT is engaged to work on Natural Flood management in connection with the flooding experienced in the upper reaches of the Hughenden Stream. His client ultimately is Bucks Council.

Sarah Mustapha and I met with Andrew and Chels Hotham (Andrew’s colleague and engagement officer) last week. This was essentially for us to provide an introduction to the DIG and for us to inform them as much as possible about our experience with all aspects of flooding (sewage, stream, groundwater, surface water) affecting our area. He wanted to understand our knowledge of risk points, experience with dealing with the Council and so on.

After the meeting we did a brief walk round the lower part of the Valley – the area most affected by sewage flooding in recent years. Then we moved on to the Warrendene area which Andrew has already visited, and we picked up David Anderson for a drive up towards Hampden Crossroads. David is a long-term Hughenden resident, with excellent knowledge of the surrounding countryside and was flooded recently (in addition to several times in the past).

A significant part of Andrew’s role is to liaise with local farmers to understand flow mechanisms, come up with options for flood retention measures. Andrew will then be modelling the impact of proposed measures and when justified and agreed to by landowners, ultimately build water retention measures on the farms.  So one of the first things we did was to call at Upper Warren Farm and spoke with Sally and Simon Lloyd. This provided Andrew with significant pointers on field and farm ownerships in the area. From there we went further up Hampden Road with Andrew noting risks/opportunities along the way.

We stopped at East Lane further up. This is a steep little used lane to the left; it is primarily from the steeply sloping field on the corner that Dave had experienced a number of times large amounts of runoff from the clay capped fields down onto the road, which would then run right down into Warrendene. We finished our tour with a stop at the Hampden Arms, where Andrew was able to pick up contact information for the Hampden Estate as well as more local knowledge on our issues.

Andrew will be engaged with this work in the coming weeks, which will involve liaising with Farms on flood management measures. The ultimate aim above Hughenden Valley will be to deal & reduce water sweeping down into our village through a variety of actions including:

  • Creation of water runoff channels
  • Swales
  • Pools
  • Ditches 

In the shorter term, it is hoped that the Council can be persuaded to implement immediate changes to the Warrendene area to reduce the flooding. These could include:

  • Alterations to the Warrendene ditch
  • Creation of pooling area
  • Addition of extra resources to divert surface water from road into ditch
  • Provision of assistance to householders to prevent flood water entering properties from road
