Description: Special Report
Abstract: This report describes the construction, operation and performance of large-scale (90-cm-inside diameter and 150-cm high) lysimeters. These lysimeters can continuously monitor soil moisture flow, soil temperature and redox potential with depth, and sample soil water and soil air with depth. The rate of soil water movement to the groundwater was continuously monitored by a rain gage and a recorder. To simulatate field conditions, an automatic spray system was developed; thissystem is also described in this report. The total cost of one lysimeter isapproximately $650 (1975 estimate).The lysimeters are being used to validate a biophysical-chemical model of wastewater renovation by application to land. Detailed blueprints of the lysimeters are kept at CRREL and are available on request.
