After the disastrous flood event of 1997 in Poland, the main concern was to upgrade and modernize the existing System of Hydrological Forecasting. The new System of Hydrology (SH) that had to be developed for entire Poland was implemented as an important component of the Emergency Flood Recovery Project, financed by the World Bank. A detailed design was worked out in 2000 and a new SH was elabo...

The worsening atmospheric pollution increases the necessity of air quality early warning systems (EWSs). Despite the fact that a massive amount of investigation about EWS in theory and practicality has been conducted by numerous researchers, studies concerning the quantification of uncertain information and comprehensive evaluation are still lacking, which impedes further development in the are...

The recent flood disasters showed that available warning systems do not fully fulfill their requirements and potentials. This paper examines these regarding web-based and mobile GIS based flood information and warning systems. We present first prototypes that are being developed at the University of Applied Sciences Mainz for a pilot area at the Rhine and give an outlook on the state of art and...

Environmental monitoring is the most popular application of wireless sensor networks (WSNs). At present, WSNs have been used for a number of applications such as soil moisture monitoring, solar radiation mapping, aquatic monitoring, glacial control and climate change, and forest fire alarm. The ability to place autonomous and low cost nodes in large harsh environments without communication infr...

The reliability of weather radar data in real-time flood forecasting and early warning system remain ambivalent due to high uncertainty Quantitative Precipitation Forecasts (QPF). In this study, a methodology is presented with the objective improve results application rainfall calculated three different ways. QPF forecast four typhoon events Fèngsh?n River Basin, Taiwan, were simulated using WA...
