Última Water percolation estimated with time domain reflectometry (TDR) in drainage lysimeters Rev. Bras. Ciênc. Solo Silva,Alisson Jadavi Pereira da; Coelho,Eugênio Ferreira. Due to the difficulty of estimating water percolation in unsaturated soils, the purpose of this study was to estimate water percolation based on time-domain reflectometry (TDR). In two drainage lysimeters with different soil textures TDR probes were installed, forming a water monitoring system consisting of different numbers of probes. The soils were saturated and covered with plastic to prevent evaporation. Tests of internal drainage were carried out using a TDR 100 unit with constant dielectric readings (every 15 min). To test the consistency of TDR-estimated percolation levels in comparison with the observed leachate levels in the drainage lysimeters, the combined null hypothesis was tested at 5 % probability. A higher number of probes in the water... Tipo: Info:eu-repo/semantics/article Palavras-chave: Drainage; Water flow in the soil; Soil moisture.
