11th May 2006. BGS and University of Brighton field meeting in the Patcham catchment.

Inspecting exposed Chalk above the A27. The chalk seen here is around the boundary between the 'White Bed' and the Plenus Marls.

View to the north-east, across the Patcham valley towards the village of Pyecombe.

View west towards Devils Dyke. Devils Dyke is believed to have been formed by spring sapping/erosion. There is no longer a spring present in the valley and this thus illustrates that different hydrogeological conditions have existed in the past.

Inspecting a dew pond developed on Clay-with-flints at the crest of the South Downs.

The Flood1 recharge monitoring site. Visible are two rain gauges and the tops of profile probes for measuring water pressure distribution in unsaturated chalk.

The UK section of the FLOOD1 team.

The FLOOD1 team spent a day walking the length of the Patcham valley. The aim of the fieldtrip was to gain a better understanding of the FLOOD1 study area. Examples of lithological, geomorphological and hydrogeological variation within the valley were illustrated by the University of Brighton team and discussed by the group. The day finished with a visit to the FLOOD1 research site.
