This capability has enabled enhancements in our capacity to describe water cycle and hydrological processes. The book includes guidelines, technical advice, and practical experience to support practitioners and scientists in increasing the efficiency of monitoring with the help of UAS. The book contains field survey datasets to use as practical exercises, allowing proposed techniques and methods to be applied to real world case studiesPPN: PPN: 1882635299Package identifier: Produktsigel: ZDB-4-NLEBK | BSZ-4-NLEBK-KAUB
