| Zusammenfassung |
| Long-term simulations (3000 yr) of an idealized basin using different
tidal ranges (1, 2 and 3 m) and grain sizes (120, 480 and 960 μm) have
been performed in order to cover a range of hydrodynamic and sedimentary
conditions. Two different cell sizes (50 and 100 m) have been used to study
the impact of cell size on tidal network development. The probability
distributions of the drainage area and the drainage volume have been
computed for every simulation (during an ebb and a flood phase). Power law
distributions are observed in drainage area and drainage volume
distribution. As an objective estimation of the exponent of a power law is
an open issue, different approaches (linear binning, normalized logarithmic
binning, cumulative distribution function and maximum likelihood) proposed
by White et al. (2008) to estimate the exponent have been used to carry out a sensitivity
analysis. Our findings indicate that although all methods results in high
and significant correlation coefficients, more work is needed to develop a
universal, objective estimation of the exponent. |
