This archive contains the results from calibration experiments with trend-like data. A simple EPA SWMM flood model was calibrated with different combinations of conventional water level data and trend-like water level data. Three different measurement locations in the model were possible: the pond (s3), the outlet shaft (s5), and the basement (s6). Trend-like data of different qualities were considered: error-free data (codename "trend"), data with correlated errors ("sofi") and data with uncorrelated errors ("gaussiantrend").
