A disaggregation model of point rainfall

D. Koutsoyiannis, A disaggregation model of point rainfall, PhD thesis, 310 pages, doi:10.12681/eadd/0910, National Technical University of Athens, Athens, 1988.



A general purpose one-dimensional disaggregation model has been developed, which is referred to as a "dynamic disaggregation model". The main features of the model are the step-by-step approach method and the dynamic modification of its parameter in each individual step. The currently developed form of the model has been specialized for variables following gamma distributions with Markovian structure. A second part of the study is concerned with the analysis and modelling of the rainfall process on hourly through monthly scale, based on rainfall data of the Aliakmon river basin, Northwestern Greece. The combination of the dynamic disaggregation model and the rainfall model gave a point rainfall model which disaggregates monthly rainfall into rainfall events and subsequently into hourly depths. This final model has been coded in pascal programming language and was able to run in conventional microcomputers.
