Title: Environment Agency Available Resource Methodology Assessments in Catchment Abstraction Management Strategy Trial Areas Second Draft Report
Author: National Groundwater and Contaminated Land Centre
Document Type: Monograph
This report describes the trialling and development of the Available Resource Methodology (ARM) as a Framework to guide the Environment Agency's assessment of water resources and abstraction sustainability. The Framework starts from a description of the conceptual understanding of the area in question. It then focuses on the estimation and plotting of natural river or groundwater outflows, the artificial impacts which abstractions or discharges have on these, and on comparison with target flows established according to in-river or other environmental or down river needs. Monthly flow comparisons are made in order to represent the seasonal variation in resource availability and abstraction impacts. Wherever possible resources are defined by the natural river flow with an integrated consideration of both surface water and groundwater abstraction impacts on this resource. The ARM trials reported were carried out in parallel with other approaches used by Agency Regional teams to assess resource sustainability as part of a national trial of the Catchment Abstraction Management Strategy (CAMS) process. These Regional approaches are also described and compared with each other and with the ARM which appeared to perform well as a Framework.
