Waraabinta saraarka (furrow) waxay biyaha mariyaa kanaalo yaryar oo u dhexeeya safafka dalagga. Waa habka ugu caansan dunida — qaabkiisu yar yahay, qiimihiisuna hooseeyaa, balse haddii la fiirsan ee uu xidho 25–40% biyaha.Furrow irrigation flows water along small channels between crop rows. The world's most common method — low-cost and easy, but inefficient (25–40% losses) without careful design.الري بالأخاديد — يوزع الماء بين الصفوف؛ شائع لكنه يفقد 25–40% بلا تصميم جيد.Umwagiliaji wa mifereji — wa kawaida lakini hupoteza 25–40%.

Furrows waxay ku habboon yihiin dalagga safaf ah (galley, basasha, yaanyada, qaraha), dhul sallaxan ama jiif yar (slope <3%), iyo meelaha biyaha laga keeno wabi ama ceel awood sare leh.Furrows suit row crops (maize, onions, tomato, watermelon), flat or gently sloped land (<3% slope), and sites with abundant river or well water.للمحاصيل الصفية والأراضي المسطحة.Kwa mazao ya safu.

- Dhererka saraarka: 50–200 m (kor u dhererka ciidda ka mid ah).Furrow length: 50–200 m (longer in heavier clay soils).الطول — 50–200 م.Urefu — m 50–200.
- Masaafada saraarka: waafaqsan masaafada dalagga (60–90 cm khudaarta, 75–100 cm galleyda).Spacing: match crop row spacing (60–90 cm vegetables, 75–100 cm maize).التباعد — حسب الصف.Nafasi — sawa na safu.
- Slope: 0.2–0.5% ugu fiican; aad u hooseeya = biyaha taagan, aad u sareeya = nabaad-guur.Slope: 0.2–0.5% ideal — too flat ponds water, too steep erodes.الانحدار — 0.2–0.5%.Mteremko — 0.2–0.5%.
- Inflow rate: 0.5–2 L/s saraar kasta — biyaha gaadhsiisaan dhamaadka 25–50% wakhtiga waraabinta.Inflow rate: 0.5–2 L/s per furrow — water should reach the end in 25–50% of total irrigation time.التدفق — 0.5–2 لتر/ثانية.Mtiririko.
