摘要

Th? fr?? surf?c? s??p?g? is ?n? ?f th? m?st s?ri?us f?rms ?f w?t?r l?ss in ?n irrig?ti?n ch?nn?l n?tw?rk. N?w?d?ys, ?n? ?f th? m?st p?w?rful ?nd pr?cis? t?chniqu?s utiliz?d f?r studying th? fr?? b?und?ry s??p?g? pr?bl?m is finit? ?l?m?nt m?th?d. In this p?p?r ? sl?v? pr?gr?m ?f G??-Sl?p? S?ftw?r? i.?. (S??P/W) w?s us?d f?r th? ?n?lysis ?f s??p?g? fr?m ?n ??rth?n c?n?l which h?s b??n ?p?r?ti?n?l f?r m?r? th?n hundr?d y??rs. S??p?g? fr?m t?n diff?r?nt RD w?s simul?t?d with S??P/W by using th? fi?ld p?r?m?t?rs ?cc?rdingly. Th? simul?t?d r?sults r?v??l?d th?t ?m?ngst ?ll th? cr?ss s?cti?ns th? ?v?r?ll minimum s??p?g? (6.13 x 10-5 ft3/s?c/ft) ?nd m?ximum s??p?g? (1.17 x 10-3 ft3/s?c/ft) ?ccurs ?t RD – 120+000 ?nd RD – 290+000 r?sp?ctiv?ly. T?t?l s??p?g? (disch?rg?) l?ss c?lcul?t?d by fi?ld ?bs?rv?ti?ns ?nd S??P/W simul?ti?ns w?s f?und 243.1 CUS?C (7.45%) ?nd 247.9 CUS?C (8.00%) r?sp?ctiv?ly. Th? ?v?r?ll st?tistic?l ?n?lysis ?f ?ll th? r?s??rch d?t? i.?. RMS?, M?, R.?, ?nd ?F t? ?v?lu?t? th? p?rf?rm?nc? ?f th? m?d?ls ?r? f?und t? b? 0.78 CUS?C, 0.48 CUS?C, 2.01% ?nd 99.80% r?sp?ctiv?ly. H?nc?, in c?ntr?st with diff?r?nt fi?ld ?n?lysis m?th?ds, S??P/W s?ftw?r? h?s ? pr?p?r ?bility t? simul?t? s??p?g? fr?m ??rth?n c?n?ls h?w?v?r; th? num?ric?l m?d?ls must b? c?libr?t?d f?r l?c?l c?nditi?ns.
