Нашла еще вот такой словарь:
http://translate.academic.ru/sharpcrested+weir/ru/xx/29/

водослив с острым гребнем — sharp-crested weir
водослив с плоским гребнем — flat-crested weir
гребень водослива — weir crest
гребень затвора плотины — crest of a weir shutter
гребень плотины — crest of a dam

Похоже, что "гребень" обычно означает "crest" -- так что не совсем понятно, почему в Вашем тексте "гребенка" определяется как "временный водосброс", который означает "removable weir".

Наверное, придется Вам выбрать наиболее подходящий вариант по контексту.

Notes to answerer
Asker: Гребенка не от слова "гребень", а потому что внешне напоминает гребенку.
