Description
Summary:The authors studied the physicochemical variables change in seven water swamps and seven streams outside the floodplain area in Ayapel in nine samples during the period 2006-2009. The average value of electrical conductivity in the swamp is three times less than the value of the swamps of the region. A 100 mu S/cm can be considered as discriminating among swamps with lower values, and streams with higher values. Temporary level of all evaluated forms of nutrients present differences which indicates the importance of the effect of pulse of flooding through hydrological cycle. With the decline of the column of water in times of drought, there was an increase in the concentrations of nitrogen, which are favored by the resuspended material from the bottom of the swamp. The authors found that for the same phase in successive cycles of the pulse, there are differences in the system dynamics so that when the hydrologic sampling is performed is the main factor in the behavior of the physicochemical conditions of the system.
