| Abstract | Event-based stochastic rainfall analysis technique has been proven
successful in semi-arid climatic condition, where the rainfall is
commonly summer type convective precipitation. This study deals with the
transfer of an event-based rainfall analysis technique to the tropical
humid climat e as this technique can also be applied for long lasting
rainfall events i.e. for general frontal storms. This trans fer process
includes the determination of event-based rainfall characteristics of the
studied duration as well as synthetic data generation for planning
purposes.
Bangladesh normally experiences a tropical humid climate in its
seasonal variation. Daily rainfall data of six rainfall recording
stations in the central region of Bangladesh are coll ected for this study
from the Hydrology Directorate of Bangladesh Water Development Board
(BWDB), Dhaka. With the help of existing procedure developed for s emi-arid
climatic conditions with certain modifications, the event-based
characteristics such as number of events, event durations, rainfall
depth, interevent time, etc. were determined for the studied area.
Kolmogorov-Smirnov test was considered for goodness of fit indices at the
5% significance level. Event-based characteristics along with the
generated synthetic data series showed an acceptable response in this case
study though there were some works left still to be accomplished in
transferring the method. It can be stated that the event-based technique
developed for semi-arid condition can also be applied in humid tropical
climate with certain modifications depending on the climatic conditions
of the study area concerned. |
