| Review: |
These are papers from the Symposium held in Brazil in April 2005. Groundwater indicators are based on monitoring and assessment programmes. Indicators may be used to monitor the state of a groundwater system, both jn terms of quality and quantity. The symposium aimed to aid the exchange of ideas about groundwater indicators engaged in river basin studies. The papers are divided into five groups: Indicators, indices and classification of sustainability; Modelling to understand sustainability; Sustainability and hydrological conditions; Sustainability and agriculture; and The influence of water quality and contamination on sustainability. |
