| Zusammenfassung |
| Observations of turbidity provide quantitative information about
water quality. However, the number of available in situ measurements
for water quality determination is usually limited in time and
space. Here, we present an analysis of the temporal and spatial
variability of the turbidity of an Amazon floodplain lake using two
approaches: (1) wavelet analysis of a turbidity time series measured
by an automatic monitoring system, which should be
improved/simplified, and (2) turbidity samples measured in different
locations and then interpolated using an ordinary Kriging algorithm.
The spatial and temporal variability of turbidity are clearly
related to the Amazon River flood pulses in the floodplain. When the
water level in the floodplain is rising or receding, the exchange
between the Amazon River and the floodplain is the major driving
force in turbidity variability. At high-water levels, turbidity
variability is controlled by Lake Bathymetry. When the water level
is low, wind action and Lake Morphometry are the main causes of
turbidity variability. The combined use of temporal and spatial data
shows a good potential for better understanding of the turbidity
behaviour in a complex aquatic system such as the Amazon floodplain. |
