SFB 564, B2.4 - Probabilistic assessment of the environmental fate of agrochemicals under varying land use in a watershed in Northern Thailand

This subproject aims at assessing the impact of different land use options on the loss of agrochemicals from the Mae Sa watershed together with the respective uncertainties. For this purpose, the SWAT model will be applied. The relevance of parameters and other model input will be identified by a global sensitivity analysis. The uncertainty analysis will extend beyond current approaches in that it will not only consider uncertainties, but also the spatial and temporal variability of some of the model input (e.g., application pattern, sorption and degradation parameters of pesticides).
