Thiessen polygon rainfall
WebThe catchments were each divided into subareas by Thiessen‐polygons. For each polygon the amount of discharge was calculated based on the precipitation, land use, land treatment, antecedent moisture conditions and hydrological soil group. The summation of the calculated runoff per polygon formed the inflow variable for the reservoir models. WebThiessen polygon Method In order to achieve accurate estimation of the spatial distribution of rainfall, it is necessary to use interpolation methods, for this, the Thiessen* method is considered as the most important in engineering praxis. This method assigns weight at …

Web26 Jan 2012 · Thiessen polygon method. A method of assigning areal significance to point rainfall values. Perpendicular bisectors are constructed to the lines joining each measuring station with those immediately surrounding it. These bisectors form a series of polygons, … WebThe problem with the Thiessen polygon method is that it ignores the influence of topography on the rainfall. Whether this method will be suitable for you case depends on the relief of the catchment.

Web31 Dec 2024 · The simplicity of the Thiessen polygon method derives from the assumption that the rainfall in areas between the gauges can be interpolated linearly. This is only one possible assumption, however. Other methods involve different types of interpolation, such as the annual average rainfall weighting mentioned in the previous section and inverse ... WebIn 1911, Thiessen and Alter considered problems of measuring rainfall in polygons surrounding rain gauges (dots). Given a scatter of rain gauges, they partitioned the underlying plane into polygons containing the dots in such a way that all points within any …
