Measurement and analysis techniques for water balance For the upcoming project work in Schinznach-Dorf different analysis methods will be compared with each other. In order to estimate the water balance of different areas, different measuring methods can be carried out using the appropriate indexes. The nursery Zulauf in Schinznach-Dorf covers an area of 30 ha. More than 1.5 million plants are irrigated via approx. 10,000 nozzles and 100,000 individual drip points (Garten-und Bonsaicenter Zulauf, 2019) . According to Dr. Johann Junghardt, thermal, RGB optical or NirGB multispectral data can be generated on site by remote sensing, which are then available for evaluation. On the basis of these specifications and conditions, the following question will be dealt with: Which remote sensing methods and indexes are best suited for different irrigation systems? Normalized Difference Water Index NDWI (Table 1) is an index that shows the water content of plants. The advantage of ...
