Equation for Calculating Evapotranspiration of Technical Soils for Urban Planting

Equations for calculating evapotranspiration in technical soils show great differences regarding their results. Causes are the different climatic conditions and vegetation specifics during development. Every equation of only delivers 100% correct results if it is used under same condition as was developed in. To determine evapotranspiration, loss weight plants measured a test series on load cells climate chamber. The result these development an easy-to-use equation. An at any temperature possible while using polynomial correlation. rate (in mm/m² per 24 h), temperature, type, soil have to be defined obtain output mm/day. Using well-known by Makkink, 0.12 mm/day, whereas newly calculates (1) 2.59–5.58 mm/day variant with no vegetation, (2) 3.15–4.00 Sedum floriferum, (3) 4.40–4.55 Geranium x cantabrigiense. application this will help chosen (used sector rainwater management) or without vegetation.
