This document reports the progress of the RIVERWATCH experiment from week 33 to week 41.

Progress has been achievedin most tasks. Some of the components have already arrived while others are still in the acquisition process because for instance of customs clearance. The water-land segmentation process that exploits a priori knowledge of the shoreline pose, extracted from overhead imagery was further developed and we are currently implementing a symmetry detection operator in order to exploit the mirroring effect observed in settled waters. Then, these cues will be fused for a robust extraction of the shoreline. regarding energy harvesting and management, we have specified the problem and we expect to have an instantiation of the model available for simulation during the next reporting period. During the period the USV vision based detector was further developed and the design of the UAV overhead image processing for terrain classification procee has been done and its implementation initiated. In this report we overview the overall idea with the expectation that details can be provided in the forthcoming report.
