Development and implementation of environmental protocols in river maintenance in Ireland

Abstract

Scientific studies (1990-2000) on the impacts of channel maintenance on the river corridor biota and habitat of Irish arterially drained channels identified strategies that would reduce adverse impact or provide benefit. A 10-point training programme was developed from these strategies and was rolled out to all Office of Public Work (OPW) field staff, engaged in channel maintenance, during 2003. Follow-up site visits indicated a strong degree of implementation in respect of particular actions. It was also apparent that there was a low level of uptake of value-added options, particularly those where strong liaison with fisheries was feasible. It was evident that some of the 'enhanced maintenance' diggings in the cross-section would enhance hydromorphology elements in the channel, consistent with Water Framework Directive requirements. All 10 elements are now being pursued in a new 5-year programme (2008-2012). © 2010 The Authors. Water and Environment Journal © 2010 CIWEM.
