Sap flow measurement methods for determining transpiration of forest trees and its importance for watershed management

Abstract

One of the primary goal of the watershed management is to maximize water yield with maximum quality in the fresh water producing. In order to fulfill this objective, some watershed management practices have been conducted. Amount of water consumption by trees and its precisely determination is important in terms of water balance equation in the watersheds. Measurement of tree transpiration by sap flow method has not been carried out so far in Turkey. Therefore, objectives of this study are to provide detailed information about measurement of transpiration by sap flow method, explain its superiorities compared to other methods and discuss its importance in watershed management concept.
