The temporal dynamics of particulate in the Arrayanales Creek (Cauca), organic matter was determined taking into account the events of rainfall and its effect on the amount of fine particulate organic matter (FPOM), coarse (CPOM), and total (TPOM) which input and is transported downstream from the Creek. It was raised as a aims to establish the amount and variation of lateral, vertical inputs and the transport of organic matter particulate (MOP), counting the precipitation and flow as hydroclimatic variables for this purpose ash-free dry weight (AFDW) in vertical, lateral MOP captured and transported was determined. The results show that the Arrayanales Creek is an ecosystem with a tendency towards the transport of large quantities of MOPG, with low storage and potential mechanisms for input of organic matter replanted, depending on rainfall. Precipitation mostly related to the transport of MOPG, than with MOPF. Vertical and lateral contributions were dominated by MOPG, with overall averages of 10,86 AFDW g m-2 and 6,05 g AFDW m-2 respectively. Transport in the section of study was 37,83 g m-3 TPOM, 32,88 g m-3 CPOM and 4,94 FPOM g m-3 .
