Risk assessment of potential removal of tree vegetation in the Northern Terraces locality, Hradec Králové

Popis výsledku v původním jazyce

The aim of this study was to define risks to a city park on the slopes of the Northern Terraces locality in case of potential tree vegetation removal. The study was conducted as a field survey of local pedology and vegetation cover combined with potential evapotranspiration calculation. A hydrological model PERSiST was then used to estimate the rainfall-runoff process under the conditions of a climatic &quot;standard&quot; year (2013). The results indicated that the soils consist of deep anthroposols containing lots of debris and artefacts with high permeability and little shear resistance. There were two main vegetation types: park lawn and tree vegetation. On average, the total evapotranspiration was 30% higher for tree vegetation than for park lawn. The surface runoff from tree vegetation was negligible as most of the water was used by interception and evapotranspiration or transformed into subsurface runoff. In comparison, the runoff from park lawn was almost the same as from paved areas reaching approximately 30% of total precipitation. Tree vegetation proved to be a key agent in sustaining slope stability in this locality.
