If rainfall, we have a lot of test to test the homogeneity of rainfall such as t-test, standard normal homogeneity test (SNHT), Buishand range test, Pettitt test, etc. There is possible to check the homogeneity of runoff? Any method or methodology can be apply? How to check correlation between observed runoff and rainfall.
Thanks for feedback. :)
The homogeneity test is a statistical test for detecting data variability and checking whether a data series has been sourced from homogeneous or heterogeneous
records.This is a fundamental test in hydrological statistical analysis (Kang and Yusof 2012; Qin et al. 2009). In general, when the hydrological data series is homogeneous, it means that data records were recorded with similar instruments, techniques, and environments (Kang and Yusof 2012).
Literature offers several methods of testing the homogeneity of hydrological time series data such as the standard normal homogeneity test, Buishand’s test, and Pettitt’s test (Buishand 1982; Chiu and Wang 2009; Firat et al. 2010;
Pettitt 1979; Rocha et al. 2012; Wang et al. 2007).
Kindly find my paper entitled:Long-term variation analysis of a tropical river’s
annual streamflow regime over a 50-year period
In this research, Pettitt’s test was applied to check the homogeneity of streamflow records from the Rantau Panjang station over 50 years from 1961 to 2010.

thanks Seyem. It is really helpful. Seem homogeneity test applied in rainfall can be apply to runoff too. thanks.
