“…The values of θr α n and Ks estimated by inverse modeling for the Argisols are corroborated by those obtained by Rashid et al (2015), that in an argisol cultivated with oil palm, using tension infiltrometer obtained by inverse method values of θr (0.279 to 0.291 (cm 3 cm -3 ) α (0.508 to 0.908 cm -1 ), n (1.34 to 2.032) and Ks (0.0105 to 0.0308 cm min -1 ) in points sampled between plants, values close to those obtained in this work. Naik et al (2018) estimated by inverse modeling the parameters α, n and Ks in four types of sandy, medium-textured, clayey and silty soils using accumulated infiltration data obtained by a mini-tension infiltrometer. For the soil that most closely resembles the argisol evaluated in this work, the values obtained by this author were α (0.129), n (2.473) e Ks (0.009).…”

“…In recent years, many publications have been presented by authors from several countries offering approaches and use of the inverse method models (Alletto et al, 2015;El-Nesr et al, 2014;Pollalis and Valiantzas, 2015;Rashid et al, 2015, Sedaghatdoost et al, 2017, Naik et al, 2018, Vogeler et al, 2019. Various studies have shown that micro-aggregated, strongly weathered tropical soils have different water retention properties than temperate-region soils because of differences in mineralogy and weathering history (Tomasella and Hodnett, 2004).…”

In the last few years, many studies have been published by authors from several countries offering approximations and use of the inverse method. However, the unique environmental conditions and distinct properties of the tropical soils in Brazil require extra considerations and the need to adjust these methods to tropical soil conditions. Considering the above, this determined the parameters of the van Genuchten (1980) model (θs, θr, α, n) of the water retention curve in the soils. It also determined the parameter (Ks) of the soil’s hydraulic conductivity curve by solving an inverse problem using the HYDRUS-2D model, considering cumulative infiltration data collected in the field by means of an infiltration test using the tension infiltrometer. It then compared the hydraulic properties determined by these methods in relation to the standard laboratory method. The inverse method was able to efficiently determine the water retention curves in the soils here studied; however, it was not possible to reliably determine the unsaturated hydraulic conductivity curve.

“…A minidisk infiltrometer (Decagon Devices 2012) test was conducted to determine the soil sorptivity and hydraulic conductivity of the ash-covered soils after completion of the rainfall simulation experiments. This test is widely used for measuring soil hydraulic properties because of its low price, small dimensions, and ease of use [52][53][54]. The measurements were performed according to the technical manual (Decagon Device 2012) and previous studies [54,55].…”

Fires can alter the hydraulic properties of burned soils through the consumption of organic matter on the ground surface. This study examined the effects of rainfall on the presence of soil pore clogging with varying ash layer thickness using laboratory rainfall simulator experiments. The image analysis with resin impregnation showed that rainfall impact caused plugging of soil pores at 22.2% with soil particles and 14.3% with ash particles on near surface soils (0–5 mm below). High rainfall intensities enhanced soil pore clogging by ash particles, particularly at shallow soil depths (0–10 mm). Ash deposits on the soil surface increased the water-absorbing capacity of ash-covered soils compared with that of bare soils. The rainfall simulation experiments also showed that ash cover led to a reduction in soil hydraulic conductivity, owing to the combined effects of surface crust formation and soil pore clogging. The complementary effects of soil pore clogging and water absorption by ash cover could hamper the accurate understanding of the soil hydrologic processes in burned soils.

“…Among the different procedures developed to estimate soil hydraulic properties, numerical methods involving inverse solution of Richards equation (Simunek and van Genuchten, 1997;Simunek et al, 1998;Ramos et al 2006;Rashid et al, 2015;Naik et al, 2018;da Silva Junior et al, 2020) are increasingly used. Primal advantage of inverse solution approach is that both, the soil water retention and hydraulic conductivity curves can be estimated simultaneously.…”

“…In the last years, many works have been published offering comparisons between the inverse solution method and different approaches to estimate soil hydraulic parameters. However, most of them only included direct TDI measurements or laboratory data as comparative results (Ramos et al, 2006;Naik et al, 2018;da Silva Junior et al, 2020). Also, infiltration measurements have been compared with PTFs method for estimating soil hydraulic conductivity (Lee, 2005;Mermound and Xu, 2006;Shein et al, 2015).…”

O objetivo deste trabalho é comparar o uso da solução inversa na estimativa das propriedades hidráulicas do solo com a análise tradicional de dados por infiltrômetro de disco de tensão (IDT), dados de retenção em campo e funções de pedotransferência (FPTs) comumente usadas. Os dados de campo foram coletados em uma parcela experimental localizada em Bahía Blanca, Argentina. A infiltração no campo sob condições saturadas foi medida pelo método do furo inverso e a infiltração sob condições insaturadas foi realizada com IDT. Os dados de retenção de campo (θ(h)) também foram coletados periodicamente. O software HYDRUS 2D/3D foi utilizado para otimizar os parâmetros hidráulicos do solo por solução inversa, de acordo com os dados do IDT. A condutividade hidráulica saturada medida pelo método do furo inverso (5.53 cm.h-1) e calculada pela abordagem analítica de Wooding (5.35 cm.h-1) e simulações numéricas inversas (5.36 cm.h-1) mostraram valores muito próximos. Segundo estimativas de macroporosidade, a água infiltrada é conduzida principalmente através de microporos e mesoporos do solo. Os macroporos canalizaram apenas 15.9% do fluxo total infiltrado. As curvas de retenção previstas pelos FPTs não representaram corretamente os dados de retenção em campo. O melhor ajuste entre o teor de água nas tensões específicas previstas pelas curvas de retenção e o teor de água medido no campo foi alcançado pela abordagem de solução inversa de IDT (RMSE: 0.050 cm3.cm-3). A abordagem de solução inversa demonstrou ser um método simples e prático para obter uma estimativa precisa de curvas de re-tenção e de condutividade hidráulica.
