Three control profiles 3. Shoreward limit to estimate how much it should be dredge OBJETIVES OF THE AUTOMATIC TOOL: 1. To estimate when one of the profiles reaches the threshold south limit 2. How much sand has to be dredged SubTidal Profile InterTidal Profile FIX SLOPE AND SHAPE CAMERAS

Input Good Image? Save pixel line Build a real Profile of the day if end day Save Profile Show Profile Stack NO Time step Show Profile Evolution Algorithms to extract pixel line and estimate the shoreline position Initial date and final date (date_ini, date_fin) Gap of date (gap) Profile coordinates (x1,y1) (x2,y2) Number of points (n) 1. Finds the names and path of Argus images into DB based on the data in the struct "info“ 2. Gets time series of tidal levels from epochDate1 to epochDate2 with delta of "gap“ 3. Makes an XYZ with the points of the profile Pre-Processing Images at date_n SI Next Image U,V -> I (Intensity) Shoreline position (X,Y) Tide Level and date_n (X,Y,Z) Coordinates Date of the day 4. Gets the database information relevant to the image [geometry,station, site, ip, camera, gcps, usedGCPs] 5. Converts the XYZ coordinates to UV on the image 2.
