Abstract

This study presents the results of sediment transport measurement in the Koshi River with a comparison between historic and recent measurement techniques. Based on the historic sediment measurement data for the period 1948-1981, the yearly sediment load at Barakhshetra varied between 49 and 283 million m³, with an average of 95 million m³. The coarse, medium and fine fraction contribute by respectively 19, 25 and 56% to the total sediment load of the Koshi River. The average total yearly sediment load at Chatra was estimated as 130 million m³, of which about 60 million m³ is bed material load which contributes to the aggradation on the alluvial fan. This historic data relate to measurements with depth-averaged sampler form cableways. Recent practices collect surface sediment samples from the riverbank to estimate the sediment transport in the river, which include the JPO-SKSKI and DHM sediment samples. The average yearly sediment load at Chatara on the basis JPO-SKSKI and DHM measurement correspond to 44.5 million m³ and 57 million m³ respectively. Moreover, a comparison between the percentages coarse, medium and fine sediment for the historical measurements (EDI method) and JPO-SKSKI and DHM measurements (surface sampling near the bank) concluded that sampling from the bank results in a serious underestimation of the contribution of the coarse sediment to the total sediment load of the river.
