| Zusammenfassung |
| This paper presents a detailed performance and sensitivity analysis of a
recently developed hydrological landscape classification method based on
dominant runoff mechanisms. Three landscape classes are distinguished:
wetland, hillslope and plateau, corresponding to three dominant hydrological
regimes: saturation excess overland flow, storage excess sub-surface flow,
and deep percolation. Topography, geology and land use hold the key to
identifying these landscapes. The height above the nearest drainage (HAND)
and the surface slope, which can be easily obtained from a digital elevation
model, appear to be the dominant topographical controls for hydrological
classification. In this paper several indicators for classification are
tested as well as their sensitivity to scale and resolution of observed
points (sample size). The best results are obtained by the simple use of HAND
and slope. The results obtained compared well with the topographical wetness
index. The HAND based landscape classification appears to be an efficient
method to ''read the landscape'' on the basis of which conceptual models can be
developed. |
