Retention of Coarse Particulate Organic Matter in a Stream Tropical Mountain. Bogotá, Colombia

Abstract

Retention percentage of three fractions of coarse particulate organic matter (MOPG) and discharge effect over retention of particulate organic matter (MOP) were studied during five months in three sectors of a tropical mountain stream, at Eastern hills of Bogotá - Colombia. The tropical condition of the system, showed a pattern of constant discharge although could be a different period from low and high discharge. Results showed as average value of retention percentage was high, with a negative association between flow magnitude and percentage of retention for each MOPG fraction, being more evident in small particles (rs=-0.74, p
