Abstract Traditional border irrigation designs have rarely considered that soil infiltration can vary. The design of border irrigation systems can be improved by the optimization of border irrigation discharge. Therefore, the objectives of this study were (1) to expand the scope of the existing model for estimating and verifying the performance indicators of closed-end border irrigation; (2) to analyze the effect of infiltration variability on infiltration depth variability of closed-end border ...

The accurate estimation of soil hydraulic parameters (θs, α, n, and Ks) of the van Genuchten–Mualem model has attracted considerable attention. In this study, we proposed a new two-step inversion method, which first estimated the hydraulic parameter θs using objective function by the final water content, and subsequently estimated the soil hydraulic parameters α, n, and Ks, using a vector-evaluated genetic algorithm and particle swarm optimization (VEGA-PSO) method based on objective functions b...

Soil infiltration is characterized by scale dependence, so the accuracy and reliability of indirect methods used to estimate soil infiltration properties from available soil physical data are often below expectations. This study aimed to determine the scale-dependent relationship between soil infiltration and soil physical properties and to establish pedotransfer functions (PTFs) for estimating normalization factors (FC). Field studies were conducted using double-ring infiltrometers in the first...

Obtaining reliable information on the wetting front depth of soil is beneficial to the understanding of one-dimensional (1D) vertical infiltration under border irrigation. This paper presents an approximate explicit solution to the Green-Ampt (GA) infiltration model for estimating the wetting front depth. Moreover, the model proposed in this study, the GA model, the Ali model, and the Stone model were validated and evaluated using laboratory experimental data and HYDRUS-1D simulation. Statistica...

Evaluation of furrow irrigation systems requires accurate estimation of soil infiltration parameters and Manning roughness, and the impact of variations of those parameters should be considered. The objectives of this paper were to verify the reliability of the infiltration parameters and Manning roughness estimated with SIPAR_ID software, and to analyze the impacts of different combinations between soil infiltration parameters and Manning roughness on the water trajectory and irrigation perform...
