Abstract / Summary:

The material in this report is a contribution to one of the core research projects in the Cooperative Research Centre for Catchment Hydrology (CRCCH), entitled "Development and evaluation of predictive tools for water production in natural, disturbed and managed forests".

The project aims to synthesise our knowledge of forest water balance, to generate key experimental information on the factors that determine how water, soils, trees and landscapes interact. An important facet of this work is to study water movement in the forest soils; this requires that we use soil moisture measurement equipment.

The study described in this report was carried out by Dr Sam Dasberg of the Institute of Soils and Water in Israel while he was a visiting scientist at the Canberra laboratory CSIRO Division of Water Resources. Dr Dasberg's visit was funded jointly by CSIRO and the CRCCH.

This report summarises results of a calibration and testing program for the commercially-available "Moisture Point" Time Domain Reflectrometry system. It has been an important part of the CRCCH's experimental program as the device will be relied upon to yield estimates of soil moisture status across a range of different soil environments.
