Terrain‐based catchment partitioning and runoff prediction using vector elevation data

Moore, Ian D., Grayson, Rodger B.·1991·Water Resources Research

Abstract

An automated method of partitioning catchments into interconnected elements using a “stream tube” approach and vector or contour‐based digital elevation models is briefly described. With this form of partitioning, hydrologic models can be structured based on the hydraulics of flow within a catchment and the effects of topography on runoff producing mechanisms and spatially distributed flow characteristics (such as flow depth and velocity) can be directly, and realistically, accounted for in the models. The method allows complex three‐dimensional flow problems to be reduced to a series of coupled one‐dimensional problems in areas with complex terrain. Two simple process‐oriented hydrologic models that demonstrate the utility of this form of partitioning are presented. The first models subsurface flow‐saturation overland flow and the second models Hortonian overland flow. Observed and predicted runoff hydrographs and the dynamic expansion and contraction of runoff source areas on a small laboratory microcatchment are presented. Also shown are predicted runoff hydrographs and surface flow velocities on a small rangeland catchment in the United States.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
