Description
Summary: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
