The predictive capability of a new artificial intelligence method, random subspace (RS), for the prediction suspended sediment load in rivers was compared with commonly used methods: forest (RF) and two support vector machine (SVM) models using radial basis function kernel (SVM-RBF) normalized polynomial (SVM-NPK). Using river discharge, rainfall stage data from Haraz River, Iran, results revealed: (a) RS model provided superior accuracy (NSE = 0.83) to SVM-RBF 0.80), SVM-NPK 0.78) RF 0.68),...

Abstract Understanding erosion and accretion dynamics during an entire tidal cycle is important for assessing their impacts on the habitats of biological communities long‐term morphological evolution intertidal mudflats. However, previous studies often omitted very shallow‐water stages (VSWS, water depths &lt; 0.20 m). It these VSWS that bottom friction becomes relatively strong thus are likely to differ from those deeper flows. In this study, we examine contribution effects cycle, based...

Abstract Suspended sediment is conventionally regarded as that transported by a fluid it fine enough for turbulent eddies to outweigh settling of the particles through fluid. Early work in fluvial field attributed suspension turbulence, and led notion critical threshold maintaining suspension. However, research on both turbulence structures interactions between suspended bedforms rivers has shown more complex story and, although there appear have been no studies impact aeolian...
