Radar rainfall estimates in an alpine environment using inverse hydrological modelling
The quality of hydrological modelling is limited due to the restricted availability of high resolution temporal and spatial input data such as temperature, global radiation, and precipitation. Radar-based rain measurements provide good spatial information. On the other hand, using radar data is accompanied by basic difficulties such as clutter, shielding, variations of Z/R-relationships, beam-r...
متن کاملInverse distributed hydrological modelling of alpine catchments
Even in physically based distributed hydrological models, various remaining parameters must be estimated for each sub-catchment. This can involve tremendous effort, especially when the number of sub-catchments is large and the applied hydrological model is computationally expensive. Automatic parameter estimation tools can significantly facilitate the calibration process. Hence, we combined the...
متن کاملApplication of Local Area Weather Radar (LAWR) in relation to hydrological modelling – Identification of the pitfalls in using high resolution radar rainfall data
Recent analysis of spatial and temporal resolution of rainfall and the advent of small inexpensive rainfall radars has lead to increased use of radar estimated rainfall as input to hydrological models especially in urban areas. Detailed rainfall measurements have indicated a very high spatial variation of up to 100 % of a distance of less that 200 m over a 3 hour rainfall event [Jensen and Pede...
متن کاملDistributed hydrological modelling of a heavily glaciated Alpine river basin
A glacier submodel was successfully integrated into the distributed hydrological model WaSiM-ETH to simulate the discharge of a heavily glaciated drainage basin. The glacier submodel comprises a distributed temperature index model including solar radiation to simulate the melt rate of glaciated areas. Meltwater and rainfall are transformed into glacier discharge by using a linear reservoir appr...
متن کاملEstimating alpine snowpack properties using FMCW radar
Large variations in both snow water equivalent (SWE) and snow slope stability are known to exist in the alpine snowpack, caused by wind, topographic and microclimatic effects. This variability makes extrapolation of point measurements of snowpack properties difficult and prone to error, but these types of measurements are used to estimate SWE and stability across entire mountain ranges. Radar t...
