Automatic landforms classification in River Tepalcatepec basin (México) using a digital elevation model

Abstract

The main objective of this paper is a detailed analysis of the physical environment of the Tepalcatepec River basin (through the states of Jalisco and Michoacan, Mexico). The total surface of the basin includes approximately 17.000 Km2. We have used an classification system modified from Dikau et al (1991). The results obtained let us to divide the basin of the Tepalcatepec River in five classes of main geoforms. Each class has been divided in several subclasses, so that 17 land units have been distinguished. The results show that the used method allows to identify accurately the existing land forms, and with much greater detail, an elevated number of subclasses.
