Abstract Little is known about the contribution of bedload flux to the total sediment load exported from tropical sand-bed rivers. Yet, predicting bedload transport rates contributes to better river management, more appropriate river engineering works design, accurate knowledge of sediment delivery rates, which greatly benefits sediment-related water resources management. Therefore, bedload, suspended load and runoff discharge were measured at the lower Gilgel Abay River in the Blue Nile… 
Consolidated sediment budget of Lake Tana, Ethiopia (2012–2016)
Abstract Lake sediment budgeting is a vital tool to better understand catchment sediment fluxes. It allows assessing lake lifetime and can be used to design improved catchment management plans. Over
Effects of Dam Construction in the Wang River on Sediment Regimes in the Chao Phraya River Basin
The Wang River is one of the major tributaries of the Chao Phraya River (CPR) system in Thailand as the key riverine sediment source supplying the Chao Phraya Delta that has experienced severe
Did the Construction of the Bhumibol Dam Cause a Dramatic Reduction in Sediment Supply to the Chao Phraya River?
The Bhumibol Dam on Ping River, Thailand, was constructed in 1964 to provide water for irrigation, hydroelectric power generation, flood mitigation, fisheries, and saltwater intrusion control to the
Analysis of Sediment Transport on the Upstream Code River, Indonesia
Purpose: The Code River is one of the pathways from debris flows of Mount Merapi that crosses the centre of Yogyakarta City, Indonesia. Along the Code River, there are densely populated areas, mainly
Field measurements on alluvial watercourses in light of numerical modeling: case studies on the Danube River
A methodology for field measurements on alluvial watercourses in light of numerical modeling that provides minimal data sets with detailed measurements for calibrating numerical models for flow, sediment, and heavy metal transport.


Estimating bedload transport in a large sand–gravel bed river from direct sampling, dune tracking and empirical formulas
Three methods used to estimate river bedload discharges were compared in a large sand–gravel bed river. The unit and total bedload transport rates estimated by sediment sampling, dune tracking method
Sediment transport of the Blue Nile at Khartoum
The Blue Nile supplies the Nile River with the largest proportion of water and sediment. Nevertheless, very few, often contrasting data are reported in the literature about its sediment yield. This
Suspended sediment load, bed load, and dissolved load yields from a semiarid drainage basin: A 15‐year study
[1] A 15-year record for the semiarid upland Eshtemoa catchment provides a basis for estimating the efflux of water, sediment, and solutes in a type of environment for which there is a dearth of
Relationship between bedload and suspended sediment in the sand-bed Exu River, in the semi-arid region of Brazil
Abstract Suspended sediment and bedload discharges in sand-bed rivers shape semi-arid landscapes and impact sediment delivery from these landscapes, but are still incompletely understood. Suspended
Sediment Transport Monitoring and Short Term Modeling in the Okavango Delta, Botswana
The Okavango Delta of northern Botswana comprises large wetlands that spread over an alluvial fan of 150 km in length. Only part of the fan is covered with wetlands but the repeated shifting of the
Flash flood sediment transport in a steep sand-bed ephemeral stream
Abstract This paper reports about flow and sediment transport measurements undertaken during the rainy season (July-August) 2008 on Gereb Oda, a steep, sand-bed ephemeral stream, draining the western
Bed load under low sediment transport in a large regulated river : the lower Ebro, NE Spain
This study describes the bed load transport regime observed under low sediment transport conditions and constant discharge in the gravel-bedded lower Ebro River (NE Spain). The data show a tendency

Summary Detailed hydraulic and sedimentary information is needed to accurately predict bed-load transport rates in natural gravel-bed rivers. Yet, being able to estimate maximum transport rates from
Determination of the bedload transport rate in a small proglacial High Arctic stream using direct, semi-continuous measurement
Abstract The article presents the results of a 34-day series of direct semi-continuous measurements of the bedload transport, performed during the melt season 2013 in the Scott River catchment (NW
Bedload yields for sand‐bed streams in the Ngarradj Creek catchment, Northern Territory, Australia
Bedload yields were calculated by 39 methods at the East Tributary gauge, nine methods at Upper Swift Creek gauge and 11 methods at Swift Creek gauge in the Ngarradj Creek catchment in northern
