چکیده انگلیسی
Landforms can be described and quantified into simple relief elements by parametrization of digital elevation model (DEM). In this research, we investigate the use of morphometric parameters and a new classification scheme to characterize selected elemental forms associated with landforms. We apply and test this methodology on a geomorphologically diverse region located in Central Mexico. These simple elements are known as morphometric classes and include ridge, plane, channel, pit, peak, and pass. These classes correspond to real entities and are of practical significance. The morphometric classes were grouped according to their areal parameters (ridge, plane, and channel) and pointed parameters (pit, peak, and pass), which can be used to form the basis of a system of characterization and classification of landforms. Landform elements display statistically significant compositional differences with respect to their proportions of morphometric classes. This, in turn, can be plotted onto a diagram of characterization and classification known as a double ternary diagram (DTD), which comprises both areal and pointed parameters and any combination thereof. The DTD is useful for studying geomorphological processes wherein areal and point values and properties have expressions which are topographically quantifiable.
