Title: Validation of statutory sampling sites using aerial surveillance : case study 4
Author: Environment Agency - National Centre for Environmental Data and Surveillance
Document Type: Monograph
Abstract:
This case study will assess the value of aerial surveillance in further delineating the position of sampling sites for statutory measurements. The use of aerial imagery to provide image animations for integration with numerical models will be assessed. Statutory sampling sites for the measurement of water quality arc at times in areas of high spatial and temporal variability. The sites investigated in this case study are within estuaries which are variable in space due to the interaction of riverine fresh water runoff and marine waters and in time due to the action of tides, in addition to seasonal and long term changes. Determination of the positions of sampling sites is to clearly defined criteria. An assessment of the variability around the sites will, however, determine how accurately spot sampling is monitoring water quality, and establish whether the criteria are being adhered to.
