I wonder if any of the two following words -the adverb or the adjective-, could be used in the following sentence. "Water flows impetuous, precipitously, along the Acequia Real canal, helping alders and love trees grow. Way up, in the palaces, Washington Irving rooms and his Cuentos de la Alhambra (Tales of the Alhambra), the thousand and one night tales of the Nasrid Kingdom". Thanks in advance for your kind cooperation.
