• Subject Area: Hydrogeology, Hydrology, Limnology, Urban Water Management, Water Chemistry, Integrated Water Resources Management
• Term: from 2011 to 2018
• Project identifier: Deutsche Forschungsgemeinschaft (DFG) - Project number 15232683

We develop Catchment Tomography, where the principle of imaging structures by decomposing a measured integrated signal via a moving transmitter-receiver concept is applied to catchment hydrologic response to rainfall. Precipitation events represent the moving transmitter, while stream gauges serve as receivers. Using long-term precipitation field information for the transmitter in connection with discharge time series for the receiver, we will invert the integrated signal using classical inverse theory and derive high-resolution hydraulic parameter distributions. The approach will improve as more orthogonal forcing/transmitter information from the radar is added to the system.
