Total load transport in gravel bed and sand bed rivers case study: Chelichay watershed

Assessment of spatiotemporal variations in the fluvial wash-load component in the 21st century with regard to GCM climate change scenarios

“…bed load, suspended load, wash load) and a bed function and wash load, which are independent of riverbed variation. This is a fundamental concept in the derivation of all theoretical sediment transport formulae (Einstein et al, 1940;Einstein, 1950;Bagnold, 1966Bagnold, , 1973Bagnold, , 1977Ashida and Michiue, 1972;Ackers and White, 1973;Kiat et al, 2008;Konrad, 2009;Rajaee, 2011;Xue et al, 2012;Haddadchi et al, 2013). Bed material load comprises both bed load and suspended load, which consist of grain sizes represented in the bed, and moves downstream either as bed load or as suspended material that is constantly exchanging with the bed.…”

Temporal Variation of Bed Load to Suspended Load Ratio in Kojour River, Iran

“…Their results showed that the river slope, bed sediment size, and hydraulic characteristics were the most important determinants of BL transportation. Haddadchi et al used eight empirical methods to estimate the total load in a gravel and sand bed river in Chelichay Watershed, Iran. The results indicated that the shear stress depended on the longitudinal bed slope and hydraulic parameters, while critical shear stress depended only on grain size.…”

Applicability of MEP and SEMEP for computing total sediment load (Case Study: Chelichay Catchment in Golestan Province)

“…Although a number of case studies available to predict bed load and suspended load based on formulas and intelligent methods (e.g., Gomez et al, 1989;Habersack et al, 2002;Haddadchi et al, 2013a;Altunkaynak 2010;Haddadchi et al 2013b;ZHU et al, 2007;Azamathulla et al, 2009;Azamathulla et al, 2012), but there are limited studies on evaluating total loads (Yang et al, 2009;Haddadchi et al, 2013c).…”
