The patterns of rainfall considered include uniform type (U), advanced type (A1 and A2), central-peaked type (C), and delayed type (D1 and D2).
Finally, the improved radar-based prediction and updated NWP rainfall considering bias correction are blended dynamically with changing weight functions, which are computed from the expected skill of each radar prediction and updated NWP rainfall.
Following a classical geostatistical approach, we assume the existence of an elemental space time stationary rainfall process and we consider rainfall accumulation as a regularization of this elemental process over time supports of various sizes.
The excess rainfall was considered to be constant under uniform rainfall conditions.
Four non-stationary streamflow sites (USGS data resources) of monthly total volumes and two non-stationary gridded rainfall sites (IMD) of monthly total rainfall are considered for the study.
Rainfall is considered to be a major factor influencing malaria cases in Africa [16] and a causal relationship between rainfall and malaria transmission is well recognized [17], [18], [19].
Moreover, maximum rainfall rate considered was 10 mm per h.
If +5 % of average rainfall is considered then for 90 and 75%% dependable flow it will be 433.75 and 528 cumec and if −5%% of average rainfall is considered then it will be 413.96 and 486.69 cumec, respectively.
Extensive rainfall is considered to have saturated a loose pumice ash layer on the mountains before the earthquake.
