Abstract

The traditional researches on evolution of tidal creek have been limited for the reason that precise measured data be required. On the other hand, the Remote Sensing Axis Line method (RSAL) can monitor the evolution of the tidal creek accuratly and promptly. This paper extracted the Axis lines of Xiaomiaohong creek based on one MSS image and six TM images in the period of 1979, 1987, 1989, 1993, 1995, 2003 and 2009 with RSAL and took a further analysis. The results showed that: On the basis of overlaying generated axis line and DEM (digital elevation model) data both acquired in 2003, axis line can be the substitution of the thalweg line because of similar trend and minor deviation of above two kinds of lines, which is revealed that RSAL was serviceable and effective to understand dynamic evolution of tidal creeks quickly and accurately. The upper section of Xiaomiaohong creek was depositing and growing all the time and subordinate braches were gradually disappeared, the south side of middle section possessed relatively stronger hydrodynamic force and much more subordinate branches were developing. DOI : http://dx.doi.org/10.11591/telkomnika.v12i5.4929
