Project summary

Edit project overview to modify the project summary.


The bypassing of shingle beach material from the Church Norton spit onto Pagham Beach in West Sussex (Photo 1 and Map 1) was carried out in 2009 to quickly address the loss of beach sediment from parts of Pagham Beach onto frontages downdrift from which it could not be recycled. • Bypassing was seen as an 'adaptive management' intervention that accelerated the expected future natural sediment movement. • Implementation of bypassing was quicker and cheaper than for beach recharge.
