Investigation of intense rainfalls and computation of ombrian curves in the Aegean islands

The purpose of the thesis is to contribute on the construction of rainfall intensity/frequency/duration (idf) relationships utilizing the available measurements for the Aegean islands. More specifically, with the use of the package «Hydrognomon», data by rain recorders in 5 islands were processed and idf relationships for every single island were constructed for the available years. Then, for the better reliability of the results but also in an effort to produce representative idf curves for the whole region, a unified sample of the data collected by the islands was created and improved idf curves were constructed. In these results, which are considered representative, additional analysis was performed to utilize data collected by rain gauges (which were available for even more islands). In the above analysis, some of the parameters were kept equal to those derived from the analysis of rain-recorder data.
