Abstract. Water collection from undisturbed unsaturated soils to estimate in situ water and solute fluxes in the field is a challenge, in particular if soils are heterogeneous. Large sampling devices are required if preferential flow paths are present. We present a modular plate system that allows installation of large zero-tension lysimeter plates under undisturbed soils in the field. To investigate the influence of the lysimeter on the water flow field in the soil, a numerical 2-D simulation study was conducted for homogeneous soils with uni-and bimodal pore-size distributions and stochastic Miller-Miller heterogeneity. The collection efficiency was found to be highly dependent on the hydraulic functions, infiltration rate, and lysimeter size, and was furthermore affected by the degree of heterogeneity. In homogeneous soils with high saturated conductivities the devices perform poorly and even large lysimeters (width 250 cm) can be bypassed by the soil water. Heterogeneities of soil hydraulic properties result into a network of flow channels that enhance the sampling efficiency of the lysimeter plates. Solute breakthrough into zero-tension lysimeter occurs slightly retarded as compared to the free soil, but concentrations in the collected water are similar to the mean flux concentration in the undisturbed soil. To validate the results from the numerical study, a dual tracer study with seven lysimeters of 1.25×1.25 m area was conducted in the field. Three lysimeters were installed underneath a 1.2 m filling of contaminated silty sand, the others deeper in the undisturbed soil. The lysimeters directly underneath the filled soil material collected water with a colCorrespondence to: A. Peters (andre.peters@tu-berlin.de) lection efficiency of 45%. The deeper lysimeters did not collect any water. The arrival of the tracers showed that almost all collected water came from preferential flow paths.

“…This was due to the advantages of pan lysimeters compared to other methods, including the low complexity of design, reduced disturbance of the soil during installation, and simple and cheap operation (Zhu et al, 2002). The zero-tension lysimeter is a passive sampler in a pan shape, without large side walls, that freely collects the drained water, measuring drainage volume and solute leaching simultaneously below an undisturbed soil column (Weihermuller et al, 2007;Robison et al, 2004;Zhu et al, 2002). It minimizes the surrounding matric potential fluctuations and potential bypass flow resulting in the conservancy of natural and regular percolation patterns if sprinkler irrigation is uniformly applied in an area larger than the lysimeter area (Lehr et al, 2005).…”

“…A number of techniques and geometries of leachate collection devices have been tested and reviewed over recent decades (Hangen et al, 2005;MorenoJiménez et al, 2011;Parizek and Lane, 1970;Yoo, 2001;Weihermuller et al, 2007). The most common inexpensive approaches are soil coring, suction cup (Hagedorn et al, 1999), suction plate (Kosugi and Katsuyama, 2004), wick lysimeter (Jabro et al, 2008), and zero-tension plate lysimeter (Peters and Durner, 2009;Robison et al, 2004).…”

Abstract. Deep percolation enhancement from recycled wastewater irrigation may contribute to salt accumulation and water table elevation that can ultimately cause soil and ground water degradation. Variation of drainage rate and solute leaching were investigated in an urban park containing heterogeneous landscape plants that were irrigated with recycled wastewater. Field monitoring was undertaken at Veale Gardens in the Adelaide Parklands, Australia. Based on landscape variation in Veale Gardens, two landscape zones were defined: one being largely covered with turf grasses with few trees and shrubs (MG) with the second zone being mostly trees and shrubs with intermittent turf grasses (MT). Experiments were performed on two zero-tension lysimeters placed horizontally 100 cm below ground to monitor the variation of volume and quality indicators of drained water for four seasons. The outcomes showed a significant variation of drainage quantity and quality in the MT and MG zones. The low vegetation cover in the MG zone resulted in more drained water than in the high vegetation cover (MT zone). In both zones, more drainage water was collected in winter than in other seasons. This is in spite of the input water showing a maximum rate in summer. The seasonal salinities measured in the two lysimeters showed very similar trends with the lowest salinity rate in autumn with the levels increasing through winter and spring. Chemical analyses of leachate solute and salt loading indicated no impact from using recycled wastewater.

“…The design of a passive lysimeter or WFD determines the soil tension at which it can collect a water sample, which for practical purposes ranges between 3 and 10 kPa (Hutchinson and Bond 2001;Gee et al, 2002;Weihermüller et al, 2007;Stirzaker, 2008). Given the various definitions of field capacity, and the fact that it is highly dependent on soil type (Romano and Santini, 2002), reliable methods of predicting the drainage flux within the 0-10 kPa range of soil tensions would help to choose among various designs of wetting front detectors.…”

The design of passive lysimeters or wetting front detectors determines the tensions at which they collect a water sample from an unsaturated soil. When deployed in the field to help manage irrigation, it is necessary to know the minimum flux of water that can be sampled by a passive lysimeter and how this relates to the drainage flux at field capacity. This requires a good estimate of the unsaturated hydraulic conductivity characteristic, K(h), in the wet range (< 10 kPa). We compared various field, laboratory and theoretical approaches for obtaining the K(h) function and compared these to a reference K(h) function derived by applying inverse modelling approaches to field drainage experimental data. The Van Genuchten model and three of the pedotransfer models produced K(h) functions with a root mean square error of less than 5% compared to the reference, and appear to be simple methods of obtaining a reasonable estimate of unsaturated hydraulic conductivity. However, despite the goodness of fit, there can be a 10-fold difference in conductivity at a given tension < 10 kPa estimated from the different methods. Moreover, water content at field capacity depends entirely on whether field capacity is defined as time elapsed after saturation, a set tension or a minimum flux.
