“…Many studies on infiltration have focused on the application of models for comparison or validation using data obtained through laboratory or field infiltrometry tests, including comparisons between different land uses (Mbagwu, 1995;Mishar et al, 2003;Shukla et al, 2003;Ghorbani Dashtaki et al, 2009;Haghighi et al, 2010;Duan et al, 2011;Robertson and Sharp, 2015). Despite the large number of studies on the effect of land use changes on infiltration rates (Malmer and Grip, 1990;Ghuman et al, 1991;Alegre and Cassel, 1996;Lal, 1996;Navar and Synnott, 2000;Martínez and Zinck, 2004;Ziegler et al, 2004;Zimmermann et al, 2006), additional information from studies comparing contrasting areas is still needed.…”

“…Considering the accuracy and error of the models, Horton's model was selected to simulate the FIR at each site. Although the f c of Horton's model is an empirical simulation value, it is close to a real FIR [44]. Similar to the variation trend of model parameters, the FIR at each site also showed a trend of slow increase with the increase of inner-ring diameter, and the increasing trend gradually slowed down ( Figure 5).…”

The double-ring infiltrometer is widely used to measure soil unsaturated hydraulic conductivity in the field. The scale effect of the inner and outer ring size (especially the inner one) affects the measurement results. In the semi-arid steppe, where water is scarce and transportation is inadequate, studying the scale effect caused by the inner-ring diameter of the infiltrometer can reduce the test consumption on the premise of ensuring the test accuracy. In this paper, a total of 190 double-ring infiltration tests with different inner-ring diameters (15,20,25,30, and 40 cm) and 0.33 times outer buffer index were carried out at 38 sites with five soil types in the Xilin river basin, China. Results showed that: (1) When comparing the simulated parameters of six infiltration models, parameters increased with the increase of the infiltrometer inner diameter, but the trend gradually slowed down, indicating that the increase of the infiltrometer inner diameter would weaken the influence of the infiltrometer scale effect. However, the infiltrometer with an inner diameter of 40 cm is not enough to completely overcome the scale effect. (2) Through principal component analysis, the infiltration process is mainly affected by the particle size and the initial moisture content. (3) The soil infiltration map based on infiltration tests was more practical than the soil type map, which can provide a theoretical basis for ecological and soil restoration in the future. species diversity does not reduce, but rather improves, the soil erosion resistance [13,14], and finally allows the whole ecosystem to achieve a positive cycle [15].To achieve the goal of obtaining the soil water retention characteristics of the study area, it is necessary to accurately evaluate this capacity, which can be estimated by the final infiltration rate (FIR) and infiltration time when the infiltration rate first reaches the final infiltration time (FIT). A slower infiltration rate indicates that the soil has better water retention [10]. The process of soil infiltration can be simulated in the laboratory using the ring-knife or a soil column [16,17]. However, such studies are influenced by disturbances of the original soil bulk density, porosity, and other soil physical properties. Instead, an infiltration test based on in situ undisturbed soil is capable of reflecting the original state of soil more effectively.Compared with a single-ring infiltrometer, a double-ring infiltrometer can be used to construct an infiltration buffer, which reduces the main external interference factors on the infiltration process of the inner ring [18]. Previous studies have shown that the average infiltration rate increases with the infiltrometer diameter [19,20]. Lai et al. [21] found through a large number of simulations that, compared with the outer buffering index (bi), the inner-ring diameter (di) plays a more important role in obtaining a relatively stable and representative measurement result. When the bi is equal or larger than 0.33, the buffer may meet the measureme...

“…To check the validity of each experiment and select the soil hydraulic parameters for the calibration process, Cronbach's alpha statistic ( α c ) was used (Ho, ):

α_{c} = \frac{R}{R - 1} ((), 1 - \frac{\sum_{i = 1}^{R} S_{i}^{2}}{S_{normalT}^{2}})

where R is the number of replications,

S_{i}^{2}

the variance associated with item i and

S_{T}^{2}

the variance associated with all the replications. In order to determine the best replication of the experiment with this method, Cronbach's alpha was calculated for all the replications to determine if any of the replications could be removed.…”

The main objective of this study was to investigate the sensitivity of the output parameters of SIRMOD software relative to initial soil water content. The treatments consisted of three irrigation water qualities, two types of soil water content management (FC and 30% FC; FC is field capacity) and three irrigation events. The HYDRUS‐1D software was calibrated to simulate infiltration under different initial soil water contents. Subsequently, the infiltration coefficients obtained from the HYDRUS model were used to simulate the border irrigation system under the different border lengths and inflow rates using the SIRMOD software. The results showed that soil was more permeable under FC management than under 30% FC. The sensitivity of the output parameters of the SIRMOD software under FC was more sensitive compared to 30% FC. The high‐ and low‐sensitive treatments were in the FC and 30% FC management with high saline‐sodic water, respectively. Due to the high permeability under FC, in order to increase the irrigation application efficiency and reduce its sensitivity, the inflow rate should be greater while border length has to be less, compared to 30% FC. Sensitivity analysis of the output parameters showed that the advance time and tailwater fraction were identified as the most and least sensitive parameters, respectively. © 2019 John Wiley & Sons, Ltd.
