2. Summary

 

- This paper suggested a new approach to improve rainfall forecast performance using an artificial neural network (ANN).  

 

- The study area of this research was Bangkok and the data sets consisted of 4 years of hourly data from 75 rain gauge

  stations and meteorological information at the surrounding stations.

 

- Different network types were tested with different kinds of input data sets to provide forecasts in a near real time schedule.

 

- The results of training processes indicated that a feedforward ANN model with hyperbolic tangent function had the best

  training performance for rainfall prediction.

 

- The results showed that ANN predicted rainfall for Bangkok from 1 to 3 hours ahead with high performance.

 

- And the sensitivity analysis showed that the most important input parameter besides rainfall itself was the wet bulb temperature.

 

 

 

3. Application to research

 

- The developed model and approaches can still be used for hydrological management flood management and low impact

  developments (LIDs) for the urban areas.

 

- The results of sensitivity analysis can be used to determine the dominant model inputs, as the suggested approaches are applied

  to deep learning algorithms.
