Opis:
Real-time forecasting of high water levels at the mouth section of the Odra river is important for the safety conditions of shipping, shipyard works, river banks pro-tection, flood control and overall management of aquatic environment in the area. While numerical hydrodynamic models offer one possible solution, such models require forecasting of all boundary conditions and forcing data, calibration of model parameters and are often too complex and time consuming. These models are not very suitable for real-time forecasting where fast solutions are required to provide ad-equate lead time. Simpler approaches offered by artificial intelligence methods such as artificial neural networks and fuzzy rule-based systems are thus becoming more attractive and promising alternatives. These methods provide a fast, sufficiently good and low-cost solution. In this paper, an application of Adaptive-Network-Based Fuzzy Inference System (ANFIS) is presented for real-time forecasting of water levels at Police on the mouth section of the Odra river.

Opis:
In this study, we analyzed and compared the data of meteorological parameters such as pressure, temperature and relative humidity, obtained with the Microwave Radiometer Profiler (MWRP) and radiosonde. The MWRP was deployed at Aryabhatta Research Institute of Observational Sciences (ARIES) Nainital, during Ganges Valley Aerosol Experiment (GVAX) in order to carry out the vertical profiling of these meteorological parameters, for a period of 10 months (June 2011 to March 2012). Simultaneously, four radiosondes were launched in a day during the entire campaign. For MWRP, quality checked vertical profiles of the data archived for the months of February (winter) and March (spring) 2012, are analyzed on the basis of diurnal and monthly variations of height above mean sea level (AMSL) from 2 km to 12 km. The analysis showed that the same pressure variation for both the observations during February and March 2012. However, significant differences in the variation of temperature and relative humidity were observed. For the mentioned period, MWRP observations of pressure and temperature showed relatively lower values as compared to radiosonde on going above from 2 to 12 km. The correlation between MWRP and radiosonde observations have been calculated for the above-mentioned parameters. A strong and significant correlation (0.90 to 0.99) for temperature and pressure were observed between MWRP and radiosonde observations, however, the insignificant correlation has been found in the case of relative humidity.
