“…Many water infiltration models have been developed to simulate subsurface water flow in furrow irrigation. On the one hand, analytical models such as the Philip model and empirical models usually quantify the applied water volume (Esfandiari and Maheshwari 1997;Moravejalahkami et al 2009). Either the Philip equation or modified Kostiakov equation combined with wetted perimeter simulated cumulative infiltration very well over time (Liu and Lu 1989).…”

Simulation of soil water dynamics for uncropped ridges and furrows under irrigation conditions. Can. J. Soil Sci. 93: 85Á98. The ridge-furrow planting system combined with furrow irrigation can effectively increase soil moisture storage and improve water use efficiency in the semi-arid region of China. The precise soil water dynamics in ridge-furrow systems must be known in order to properly design ridge-furrow geometry and improve irrigation uniformity while reducing deep water percolation. The objective of this study was to investigate soil water distribution in the cross-sectional ridge-furrow infiltration, through laboratory experiments and numerical simulations. Six experimental treatments with three soil types (silty clay loam, silt loam, and sandy loam) were tested to monitor both soil water movement and cumulative infiltration in rectangular soil chambers. The HYDRUS-2D model was calibrated and experimentally validated to simulate soil water dynamics. The root mean square error (RMSE) and coefficient of determination (R 2) provide a satisfactory quantitative comparison of the goodness-of-fit between observed and simulated cumulative infiltration. The optimized parameters were accurate and the observed and simulated values were very close, which demonstrated HYDRUS-2D as a reliable tool for accurately simulating soil water movement and applied water volume in ridge-furrow irrigation system. In finer soil, the wetted vertical and horizontal distances were equal and soil water distribution was more uniform than that in coarser soil. A high potential of deep water percolation was produced in sandy loam soil. Cumulative infiltration decreased with the increase of initial soil water content, whereas the volume of wetted soil increased with the increase of initial soil water content. Narrow furrows for crops with deep rooting depth and wide furrows for crops with shallow rooting depth were selected in irrigation design. The 40 cm furrow size and higher furrow water depth (water level) were recommended in a ridge-furrow irrigation system.

“…With regard to that the third irrigation was applied after 78 days of 1st irrigation, a reduction in advance time was observed as 15-22 % in FT 3 (24 × 5) and FT 4 (24 × 3) plots, respectively, as compared with conventional irrigated plots ( Table 2). A higher value during 3rd irrigation contrast to first irrigation may be due to compaction of soil and less infiltration losses in the irrigated plots [6]. It is obvious from the data that less time was required to complete the advance phase in film hole irrigated borders compared with conventional irrigated plots.…”

Film hole irrigation is relatively reported efficient irrigation technique amongst the others by Chinese's researchers. Film hole irrigation refers to bordered field completely covered with plastic sheet having holes of equal sizes through which seedlings come out. Field experiments were conducted at Postgraduate Agriculture Research Station to check its effectiveness and performance in terms of advance rate on sunflower crop for various sized borders having Fine Sandy Loam soil. Tube well irrigation water was applied with an average discharge of 21 l/s and field data were collected from each plot during 1st, 2nd and 3rd irrigations. Results of the study revealed that advance time taken during film hole method in completing the advance phase was comparatively less as compared with the conventional irrigation. Water saving of 37-45 % was observed by film hole irrigation, and the yield of sunflower crop was 23-30 % higher as compared with conventional irrigation. The field management issues were also discussed and addressed properly.

“…The volume-balance (VB) equation provides some simplifying assumptions for predicting advance data (Elliott and Walker, 1982;Shepard et al, 1993;Valiantzas, 2000). The VB equation is also the basis for a wide variety of infiltration parameter estimation techniques based on water advance data (Esfandiair and Maheshwari, 1997;Valiantzas et al, 2001;Sepaskhah and Afshar-Chamanabad, 2002). Elliott and Walker (1982) developed the two-point method and assumed that infiltration follows the modified Kostiakov formula.…”

“…Their method is believed to lead to errors. Maheshwari (1988) and Esfandiair and Maheshwari (1997) proposed methods of determining infiltration parameters based on water advance data and depth of water in surface irrigation, but their method involves rather complex techniques. Gillies et al (2007) studied temporal inflow variation in the inverse solution for infiltration parameters in surface irrigation.…”

Based on the volume balance (VB) equation, the surface water profile was shown to be a power function and Philip equation equal to the Kostiakov–Lewis equation when the infiltration parameter a = 0.5. With this assumption, an equation was proposed for estimating infiltration parameters together with Manning roughness. The method requires only multi‐point water advance data of border irrigation. Solving the equation requires use of the nonlinear least‐squares fitting technique by Matlab software. The proposed method was validated with field experimental data and some reported border tests. The solution procedure was analysed, the results showing that the values of infiltration parameters S and A are not changed, but Manning roughness n varies when σh were given different values (0.70, 0.75, 0.80, respectively). Alternative measures of subsurface water storage and water advance trajectory were used to validate the method. Errors between measured and estimated were 2.0–13% for subsurface water storage, in which the infiltration parameters S and A were estimated with the proposed method. The maximum average absolute error was 6.07% for water advance in all border tests when different Manning roughness n was used (for an n value was estimated when different the shape factor of surface profile σh values were adopt by the proposed method in this paper).
