Title

LANDSCAPE ANALYSIS AND DIGITAL TERRAIN MODELING USING WITH GEOMORPHIC SURFACES IN PORTION OF CENTRAL ZAGROSS MOUNTAINS

Pages

Abstract

 When allow for continuum in components of Landscape-Soil system, studies must be on basis of HIERARCHY SCALE. Data of Landscape-Soil system has straight relation with spatial information. For this reason, analysis of terrain properties has increasingly overlapped with Geographical Information System (GIS). A DIGITAL TERRAIN ANALYSIS (DTA) model derived from Digital Elevation Model (DEM). (DTA) model indexes are served to study of geomorphic surfaces and landforms in toposequence. Area of 278ha is studied in region of Ayej terrestrial dam, Jouneqan east, province of Chaharmahal and Bakhtiary in Iran. Some properties of geomorphic levels is measured by remote sensing and DIGITAL TERRAIN MODELING (DTM), such interpolation and slicing methods. Then digital terrestrial indexes, as STREAM POWER INDEX (SPI), SEDIMENT TRANSPORT INDEX (STI), and WETNESS INDEX (WI) obtained of (DEM) for six transects or sequences in study area. Every spatial situation that (SPI) to be increased, velocity and volume of flood-water were upward, as (STI) increased and (WI) reduced in its minimum. For all of sequences (STI) confirmed correlation with (SPI) closely, except 4 sequence. In sequence 4, (WI) harmonized with (STI) and traversed process of climb. Therefore sediment accumulation and water influence caused more development soils in sequence 4. In sequences 1, 2, 3, 3, 5, and 6 increased (SPI) and (STI) harmonious, reduced (WI), and caused less development soils. Percentage of slope, water influence and volume sediments are the most affected factors on configuration of landscape and landform in study area. Goal of this research was primary study landscape analysis by multiattribute and multiobjective methods, as soil survey realized for land suitability evaluation.
