Evaluation of random forests and Prophet for daily streamflow forecasting

Abstract: Abstract. We assess the performance of random forests and Prophet in forecasting daily streamflow up to seven days ahead in a river in the US. Both the assessed forecasting methods use past streamflow observations, while random forests additionally use past precipitation information. For benchmarking purposes we also implement a naïve method based on the previous streamflow observation, as well as a multiple linear regression model utilizing the same information as random forests. Our aim is to illustrate impo… Show more

“…In this Section, we examine the streamflow forecasting case study by Papacharalampous and Tyralis [132], and how this could have been improved, by considering the findings of Sections 2-4. Papacharalampous and Tyralis [132] use previous-day observed streamflow and precipitation as predictor variables to produce next-day forecasts; i.e., a common problem in hydrology (see e.g., Table 1), where numerous machine learning algorithms have been applied.…”

Papacharalampous and Tyralis [132] use previous-day observed streamflow and precipitation as predictor variables to produce next-day forecasts; i.e., a common problem in hydrology (see e.g., Table 1), where numerous machine learning algorithms have been applied. Forecasts are generated by implementing random forests (specifically the ranger R package, with root mean square errors and mean absolute forecast errors as performance indicators), with recursive retraining (i.e., the algorithm is retrained based on past data at each step of the forecast sequence), and predictor variables selected using linear metrics (i.e., the estimated streamflow autocorrelations, and the estimated cross-correlations between precipitation and streamflow, at different lag times).…”

“…For benchmarking purposes, we also apply the working methodology using the linear regression model (see e.g., James et al 2013;Hastie et al 2009) as error model, and the two naïve probabilistic data-driven schemes. For the merits of using benchmarks in hydrological modelling, the reader is referred to Pappenberger et al (2015); see also benchmarking examples in Montanari and Brath (2004), Papacharalampous and Tyralis (2018), Papacharalampous et al (2018aPapacharalampous et al ( ,b,c, 2019a, Quilty et al (2019), Evin et al (2014), Sikorska et al (2015), Papacharalampous (2017, 2018), Tyralis et al ( , 2019a, and Xu et al (2018).…”
