Handbook of Source Yield Methodologies

ISBN: 1 84057 736 3
Published Date: 05/08/2014

Tha Handbook of Source Yield Methodologies provides practitioner-focussed and technically-oriented guidance on yield assessment methods for both surface water and groundwater sources. Aiming to support analyses required as part of Water Resource Management Plans, the handbook covers good practice methods currently used within the UK water industry, but also draws on international experience where appropriate.

The handbook discusses how and when different methods might best be applied and provides direction on data requirements and sources of uncertainty. Previous guidance that is still considered good practice is highlighted, however the handbook also documents innovative variations on established techniques that have helped water companies to improve robustness in estimated source yield and mitigate for common problems. Generic guidance is also provided on topics such as reporting of assessments and the need for clear documentation with assumptions stated. A number of worked examples are provided in order to help first time users gain practice in applying yield assessment methods.

Evaluation of New Methods for 2019 and Beyond

Published Date: 07/08/2012

The research project titled 'Water Resources Planning Tools 2012', with a primary focus on the Deployable Output (DO) and the Economics of Balancing Supply and Demand (EBSD) methods, has resulted in improvements to the existing water resources planning tools. These tools include methodologies, guidelines and modelling approaches associated with the production of water management plans.
The project developed risk-based DO and EBSD methods. These methods are scalable and allow planners to choose and use techniques of different levels of sophistication, proportional to individual needs, planning issues and available data sets. The improved methods incorporate levels of service to customers. This is highlighted through trade-off relationships between efficient EBSD programmes balanced with water system reliability.
The project also evaluated new methods to respond to specific longer term planning needs, such as the need for new forms of economic appraisal.
The Summary report has a series of five additional project outputs attached on CD-ROM.
