                         dealing with the effects of many natural phenomena. In particular, 
                         floods can turn into dangerous events. This paper introduces an 
                         algorithm to detect and estimate the water level of an urban 
                         stream. Using cameras and well defined image processing 
                         techniques, we analyze several images of a real stream, aiming at 
                         finding the water depth, with encouraging results. Our approach 
                         differs from more traditional measurement methods, where 
                         specialized equipment are considered, which must be directly 
                         inserted on the measurement spot. Through a validation using real 
                         images, we demonstrate that our method is a viable alternative to 
                         estimate the water level, using cheaper and generic hardware.",
