| Zusammenfassung |
| Spatio-temporal patterns of small water bodies (SWBs) under the influence of
temporally varied stream flow discharge are simulated in discrete space by
employing geomorphologically realistic expansion and contraction
transformations. Cascades of expansion-contraction are systematically
performed by synchronizing them with stream flow discharge simulated via the
logistic map. Templates with definite characteristic information are defined
from stream flow discharge pattern as the basis to model the spatio-temporal
organization of randomly situated surface water bodies of various sizes and
shapes. These spatio-temporal patterns under varied parameters (λs)
controlling stream flow discharge patterns are characterized by estimating
their fractal dimensions. At various λs, nonlinear control
parameters, we show the union of boundaries of water bodies that traverse
the water body and non-water body spaces as geomorphic attractors. The
computed fractal dimensions of these attractors are 1.58, 1.53, 1.78, 1.76,
1.84, and 1.90, respectively, at λs of 1, 2, 3, 3.46, 3.57, and
3.99. These values are in line with general visual observations. |
