Regional Frequency Analysis at Ungauged Sites with Multivariate Adaptive Regression Splines

Abstract: Hydrological systems are naturally complex and nonlinear. A large number of variables, many of which not yet well considered in regional frequency analysis (RFA), have a significant impact on hydrological dynamics and consequently on flood quantile estimates. Despite the increasing number of statistical tools used to estimate flood quantiles at ungauged sites, little attention has been dedicated to the development of new regional estimation (RE) models accounting for both nonlinear links and interactions betwe… Show more

“…The MARS model can be seen as a flexible extension of GAM, expressed as a linear combination of BFs and their interactions (Msilini et al, 2020). It is a flexible nonparametric regression approach that can deal with high‐dimensional data.…”

“…Ouarda et al (2022) used GAM also and temperature‐duration‐curves to develop a method for estimating river water temperature at ungauged sites, which they tested on 126 river thermal stations in eastern Canada and found to be robust and more accurate than a simple averaging method. The MARS approach has also been applied in various contexts, including the modeling of daily lake surface water temperature (Heddam et al, 2020), regional flood frequency analysis (Msilini et al, 2020) and streamflow simulation (Al‐Sudani et al, 2019). Saadi et al (2022) also used MARS, in addition to GAM, to simulate daily mean PTRA.…”

“…On the other hand, the execution speed of the MARS model is very high and there is no need to spend so much time. The MARS model has high accuracy in simulating PCP (Abraham et al 2001), flow discharge (Kisi et al 2022), suspended sediment load (Esmaeili-Gisavandani et al 2022) and flood (Msilini et al 2020).…”
