CLIMATIC CONTROLLED FLUVIAL TERRACES AND HUMAN USAGE OF THE TERRACES


Climate and tectonism are most important control mechanisms which monitor forming fluvial terraces. The influence of the climatic changes on the fluvial systems causes different terraces in terms of sedimantological and morphological structures. This difference reveals the importance of fluvial architecture for the paleo-environment analysis. However the information of he interaction between climate and fluvial system is not clean everytime. For instance, it is one of the most important questions that the terrace sedimantation that formed in a climatic cycle (sequential warm and cold periods) can be formed by the tectonic accumulation-erosion processes or by the different factors like as the lateral migration of the rivers. Besides the other discussing topics which reverse the simplex for the interaction of climate-river systems are below. a. Is there any characteristic sedimantary structure in the terrace sections? Can be determined accurately the forming mechanism of every sedimantary layers. b. What are the relative ages of the sedimantary layers and their erosive phases which formed in a fluvial incision-accumulation cycle? Which processes and phases are consistent? c. Which scenarios can analysed the preservation of the terraces sequences which related to the climatic cycle? d. How the finding about human usage of fluvial areas can obtain, and which information can be derived from these findings? This article aims to search the answers for these questions.
