Abstract

This numeric data package provides data sets, and accompanying documentation, on site characterization, system performance, weather, species composition, and growth for the Throughfall Displacement Experiment, which was established in the Walker Branch Watershed of East Tennessee to provide data on the responses of forests to altered precipitation regimes. The specific data sets include soil water content and potential, coarse fraction of the soil profile, litter layer temperature, soil temperature, monthly weather, daily weather, hourly weather, species composition of trees and saplings, mature tree and sapling annual growth, and relative leaf area index. Fortran and SAS(TM) access codes are provided to read the ASCII data files.For access to the data files, click this link to the CDIAC data transition website: http://cdiac.ess-dive.lbl.gov/epubs/ndp/ndp078a/ndp078a.html

The Walker Branch throughfall displacement experiment: An overview, field performance data, and initial growth responses

Journal Article Hanson, P J ; Todd, D E ; Harter, K M - Bulletin of the Ecological Society of America

At Walker Branch Watershed a group of interdisciplinary scientists are conducting the Throughfall Displacement Experiment, a stand-level manipulation experiment that provides the appropriate environment for mechanistic studies of ecosystem and plant-level responses to changing precipitation inputs to an upland oak forest. Soil water is being manipulated by a gravity-driven transfer of one third of the throughfall precipitation from a {open_quotes}dry{close_quotes} to a {open_quotes}wet{close_quotes} treatment area. The experimental system is able to produce statistically significant differences in soil water content in years having both extremely dry and extremely wet conditions. Comparisons of pre- and post-installation soil temperature measurements have documented themore »« less
Field performance of the Walker Branch throughfall displacement experiment

Technical Report Hanson, P J ; Todd, D E ; Edwards, N T ; ...

The authors are conducting a large-scale manipulative field experiments in an upland oak forest on the Walker Branch Watershed in eastern Tennessee USA to identify important ecosystem responses that might result from future precipitation changes. The manipulation of soil moisture is being implemented by a gravity-driven transfer of throughfall precipitation from one treatment plot to another. Throughfall is intercepted in {approx} 2,000 subcanopy troughs (0.3 x 5 m) suspended above the forest floor of the dry plots ({approx} 33% of the ground area is covered) and transferred by gravity flow across an ambient plot for subsequent distribution onto the wetmore »« less
Description and field performance of the Walker Branch throughfall displacement experiment: 1993--1996

Technical Report Hanson, P J ; Todd, D E ; Huston, M A ; ...

The authors are conducting a large-scale manipulative field experiment in an upland oak forest on the Walker Branch Watershed in eastern Tennessee to identify important ecosystem responses that might result from future precipitation changes. The manipulation of soil water content is being implemented by a gravity-driven transfer of throughfall from one 6400-m{sup 2} treatment plot to another. Throughfall is intercepted in {approx}1850 subcanopy troughs suspended above the forest floor of the dry plot and transferred by gravity flow across an ambient plot for subsequent distribution onto the wet treatment plot. Soil water content is being monitored at two depths withmore »« less
Throughfall Displacement Experiment (TDE) Ecosystem Model Intercomparison Project Data Archive

Dataset Hanson, P. J.

This archive provides and documents data from a project whose purpose is to compare the output of various ecosystem models when they are run with the data from the Throughfall Displacement Experiment (TDE) at Walker Branch Watershed, Oak Ridge, Tennessee. The project is not designed to determine which models are "best" for diagnosis (i.e., explaining the current functioning of the system) or prognosis (i.e., predicting the response of the system to future conditions), but, rather, to clarify similarities and differences among the models and their components, so that all models can be improved.
