Running head: Sap flow in riparian trees Transpiration of cottonwood/willow forest estimated from sap flux

The porous media model for the hydraulic system of a conifer tree : linking sap flux data to 1 transpiration rate

1 Linking sap flow in tree boles to plant transpiration continues to be a fundamental and 2 practical research problem in physiological ecology and forest hydrology. Many models have 3 been proposed to describe water movement within trees with varying degrees of success. The 4 prevailing resistance-capacitance (RC) circuit models have the advantage of being easy to 5 implement. However, RC mode...

Many models have been proposed to describe water movement within trees with varying degrees of success.

Sap flow estimates of stand transpiration at two slope positions in a Japanese cedar forest watershed.

We determined the amount of information needed to estimate watershed-scale transpiration in a Japanese cedar (Cryptomeria japonica D. Don) forest from sap flow measurements of individual trees. Measurements of tree biometrics (diameter at breast height (DBH) and tree sapwood area (AS_tree)), and tree-to-tree and radial variations in xylem sap flux density (Fd) were made in two stand plots, an u...
