Mathematical Clarification of the Cause of Ill-Conditioning of the Coefficient Matrix in Volterra Series Model of River Runoff Phenomena
Takashi Hatakeyama · IEEJ Transactions on Electronics Information and Systems · 2024
Volterra series was applied to river runoff phenomena to model the input-output nonlinear relation between rainfall and runoff of rivers. The application results were reported in “Electrical Engineering in Japan” (vol. 98, 101). In the report, good results from modeling and simulation were shown, meanwhile unfavorable results were also shown in some cases depending on modeling condition.
