Abstract
Quantitative information on the state of a coastal system is of vital importance for decision making in the field of Coastal Zone Mangement (CZM). In this paper we demonstrate the utility of video monitoring for CZM at spatiotemporal scales of meters to kilometers and months to years in the context of the Dutch CZM policy of 'dynamic preservation of the coastline'. In order to take maximum advantage of the high spatial and temporal resolution of video-derived data we slightly modify the Coastal State Indicator (CSI) presently in use. This is allowed since the new CSI still serves the overlying strategic and operational objectives. It is shown that the 'intertidal' momentary coastline position (MICL) provides information that is comparable to the currently used momentary coastline position (MCL). Owing to the large spatial and temporal resolution of the video-derived data, error hands for the predicted MICL position are reduced by about 30 % and chances for missing erosion hotspots are virtually zero. In addition, this approach offers the possibility to develop a more advanced benchmarking procedure in which the future MICL position is defined in terms of probability.
