Title: Low flow augmentation study : River Nar : Phase 1. Stage 1 : draft planning report
Author: National Rivers Authority Anglian Region
Document Type: Monograph
Abstract:
Mott MacDonald has been appointed by the National Rivers Authority (Anglian Region) to undertake a study of the Rivers Nar and Wensum. Both river catchments are located in north Norfolk. The rivers are fed by groundwater from the Chalk aquifer and are important sources of abstraction for public water supplies. The catchments are also attractive natural habitats with considerable recreational value. River flow augmentation from groundwater may therefore be necessary to maintain both water supplies and river levels. The objectives of the study are twofold: a short term (Phase 1) assessment of available hydrological and hydrogeological data, leading to augmentation well site selection, engineering design and implementation to meet augmentation requirements in the event of continuation of a drought through the summer of 1990; groundwater/surface water interlinked catchment modelling to determine suitable long term augmentation requirements (Phase 2). Environmental assessment forms an important part of the study in considering the impact of augmentation schemes on habitats, particularly woodland and wetland.
