Abstract

Nowadays,- geomorphologic studies constitute the principle and foundations of studies of natural resources. In this study, our attempt was made to recognize, segregate and reveal the units and main geomorphologic phenomena of the southern Chahar-Mahal Va Bakhtiari. Such units includes: 1. MOUNTAINS, 2. Hills and high grounds (stoney hills and high grounds and alluvial hills and high grounds) 3. Alluvial PLAINS MOUNTAINS of the studied area, high with rather sharp precipice peaks, very steep slopes and narrow and mainly V-shaped valleys. Main factors involved in EROSION of uneven nesses of this unit climate (type of precipitalations, intensity of rainfalls and temperature range), topography, type of formation and surface run off were studied. In this unit, all types of physical, chemical and biological EROSIONs are discernable and LANDSLIp, debris and LANDSLIde are part of the mass movements on the mountain slopes of this region. Bakhtiyari conglomerate formations, sand stones and marns of fars group have formed stoney hill knolls of the studied region. in this unit peaks of hillknolls are round and circular and pnltile of the slopes are mostly convexed. Also effects of physical destruction and chemical decomposition are clearly evident in this unit. Alluvial hill knolls in clay and marn formations are seen in the north west of the region. Water EROSION in different ways has played a significant role in modification of the uneven nesses of this region. CREEP, solifluxion, LANDSLIde and narrow creeks are amongst the phenomena exiting in this region. Alluvial Slope PLAINS present in the under studied region include Alloni and Jamal PLAINS. The Alloni is amongst the PLAINS rised as a result of pressure suhsidences at the foot of Dena FAULT. The most interesting phenomenon found in Jamal plain is God-Jamal which, infect, is a small closed basin with its topographic slope towards the center from which the surface waters do not got out. The central plain in the under studied region is located in an alluvial strata formed from the sedimentary deposits of the two rivers of Khanmirza from the north east and Chelehkhaneh from the southeast. In this plain rill, and sheet EROSION the surface and thalluses on steep slopes are clearly seen. Main morphologic forms in this region include riverine deposits, alluvial terraces, lake deposits, sources and alluvial fans studies in this research.
