“…Meanwhile, many researchers clearly demonstrated that soil infiltration parameters and Manning roughness vary considerably between the furrows within the same field (Schwankl et al, 2000;Oyonarte & Mateos, 2003;Mateos & Oyonarte, 2005;Wang et al, 2009;Zhu et al, 2009;Gillies et al, 2011), and indicated that the variations between furrows are significant factors for the advance trajectory and performance of surface irrigation. Previous researches have often used representative values of infiltration parameters and roughness to simulate the advance trajectory and performance for the whole field scale, thereby ignore the inter-furrow variability (Álvarez, 2003;Eldeiry et al, 2005;Sánchez et al, 2009;Reddy et al, 2013).…”

“…Rice et al (2001) they recommended to implementing a tail water recovery system and improving irrigation scheduling would potentially increase irrigation efficiency and reduce the over-irrigation and nitrate leaching observed for the commercial cotton production system. Oyonarte and Mateos (2002) illustrated that the spatial variability of the soil hydraulic characteristics is one of the variables determining irrigation performance. Relative seed yield of some sunflower hybrids was unaffected by soil salinity up to 4.8 dS/m.…”

Field experiment was conducted along two successive seasons of winter (2004/2005) and summer (2005) at Maryout Experimental Station of the Desert Research Center, to evaluate the performance of alternate-long furrow irrigation system, using three irrigation water inflow rates on faba bean and sunflower crops productivity grown in calcareous soil. The experiments carried out in a split plot design with four replicates at random procedure. Irrigation system treatments were used as the main plots (120 m length with longitudinal soil surface slope 0.25%) namely: every long-furrow irrigation (EFI), and alternate long-furrow irrigation (AFI). Three different water inflow rates designated as Q1, Q2, and Q3 represented the sub plots: 105, 90, and 65 lpm/furrow, respectively. The irrigation performance was evaluated through application efficiency (AE%) and distribution uniformity (DU) parameters. Irrigation water use efficiency (IWUE) was estimated, which is related to water management by different treatments. The obtained results indicated that application of AFI led to high significant interrelations between the values of seed yield and increases in AE% and DU values compared with EFI treatments. The highest mean DU values in 1 st. and 2 nd. seasons were 0.85 and 0.83 obtained by Q2 and Q1 treatments, respectively. Both faba and sunflower seed yield had significant increases with increasing the inflow rates under both studied irrigation systems. The highest yield mean value, with faba bean season, was 1046.5 kg/fed., while with sunflower season; it was 659.95 kg/fed. obtained by (AFI+Q1) treatment. The highest IWUE mean value, with faba bean season, was 0.83 kg/m 3 , while with sunflower season; it was 0.27 kg/m 3. obtained by (AFI+Q3) treatment.

“…Other researchers reported that in a clay soil, stream size should increase with longer furrow lengths in order to obtain high application efficiencies 78 . These inconsistencies reveal that soil type and spatial variability are critical in furrow management 51 , 79 . Thus, surge irrigation with the optimum combination of stream size and furrow length may reduce runoff volume and subsequently improve the precise irrigation in areas with limited water availability.…”

The SIRMOD and WinSRFR models were used to model and assess the irrigation performance under continuous and surge irrigation strategies with two furrow lengths of 70 m and 90 m and stream sizes of 0.4 l/s and 0.6 l/s for each length. According to the normalized root mean squared error (NRMSE) and the relative error (RE), WinSRFR had, on average, excellent accuracy in the continuous and surge irrigation for simulating advance-recession times (NRMSE: 6.15 and 4.24% for advance time, and 2.20 and 5.20% for recession time), infiltrated water depth (NRMSE: 3.37 and 6.38%), and runoff volume (RE: 6.93 and 2.57%), respectively. SIRMOD had also, on average, excellent simulation in the continuous and surge irrigation for advance-recession times (NRMSE: 3.34 and 2.45% for advance time, and 2.28 and 6.41% for recession time), infiltrated water depth (NRMSE: 2.98 and 5.27%), and runoff volume (RE: 5.31 and 17.49%), respectively. The average of irrigation application efficiency (AE), distribution uniformity (DU), deep percolation (DP), and tail-water ratio (TWR) were 61.50, 90.25, 11.75, and 26.75% in continuous irrigation, and 72.03, 94.09, 8.39, and 19.57% in surge irrigation, respectively, which shows that surge irrigation increased AE (irrigation management performance) and DU (irrigation method performance) and reduced DP and TWR compared to continuous irrigation. Moreover, longer furrow lengths increased AE and DP under both irrigation methods, while it decreased TWR and DU. However, increasing the stream size decreased AE and DP and increased TWR under both continuous and surge irrigations. The higher stream size improved DU in continuous irrigation but reduced DU in surge irrigation. The results confirmed that both SIRMOD and WinSRFR are reliable analytical tools to evaluate furrow irrigation strategies for improving irrigation management. In conclusion, this study showed that surface irrigation models could be employed in practice by irrigation engineers and practitioners to design and define the optimized furrow length and stream size in arid and semi-arid areas where efficient and high performance irrigation strategies are required to save water and reduce water loss.
