location of most of the temporal water pools in the Aeolian sands of the Doñana
protected area (Gómez-Rodríguez et al. 2011). Gómez-Rodríguez et al. (2008) used
this detailed cartography to produce an enhanced predictive model for the breeding
habitats of the different amphibian species of Doñana. The decrease of the hydroperiod in the recent decades has been also evidenced in the Doñana water bodies
(Bustamante et al. 2016) and was shown to be one of the most relevant causes of the
decline in amphibian reproduction (Gómez-Rodríguez et al. 2010).
The multispectral information provided by the Landsat satellite images is systematically used to map water turbidity in both the Doñana marshes (Bustamante
et al. 2009b) and the Guadalquivir estuary (Díaz-Delgado et al. 2010). The analysis
of the turbidity time series has helped to quantify the spatiotemporal variability and
reconstruct the turbidity regime by differentiating extreme turbid events from longterm turbid trends (Díaz-Delgado et al. 2015). Periodic flooding masks and turbidity
maps from the landscape scale monitoring are accessible online through OGC Web
Map Services at http://venus.ebd.csic.es/imgs/ (Fig. 2).
Monitoring of Geophysical Processes
Geophysical processes are usually quite conspicuous in remote sensing images. In
the case of Doñana, the dynamics of the large sand-dune system and of the shoreline
are being reconstructed and periodically mapped by applying a very simple procedure based on image segmentation (Berberoglu and Akin 2009; Pardo-Pascual et al.
