Article
In the project "ExUS2020 - Extreme Value Statistical Investigation of Heavy Precipitation in North Rhine-Westphalia", extensive precipitation measurement data were investigated for statistical characteristics, in particular for their trend behaviour. For this purpose, measurement data were quality controlled, a comprehensive database was set up in...
Article
Measurement data management systems are a key factor in modern urban water resource management, that allow to judge data quality assessments and are thus crucial for further applications. The joint analysis of all sensor data is often not possible, due to the enormous amount of data incoming. In this study, a novel data analysis tool is presented t...
Chapter
Socio-economical development on regional, national and international basis requires intensive investigations of water resources. Water differs from other resources by the time variability of the amount of water available for use at any given moment. Non-standard seasonal distribution of hydrometeorological parameters, their fluctuations from region...

The quality of results of rainfall runoff modelling depends strongly on the hydrologic input data. In particular, for urban hydrology applications long-term rainfall series without gaps and of high quality and reliability are required in rainfall runoff and hydraulic simulation of the investigated drainage and receiving water system.The presented s...

A monthly cloud cover index (CCI) is determined as a function of the threshold cloud top temperature (IR channel), the ``reflectivity'' of the cloud (VIS channel) and the state of the environmental mean relative humidity in the upper troposphere (WV channel) using multispectral and multitemporal satellite imagery and is transformed into monthly are...
