Spatial Patterns of River Width in the Yukon River Basin Chapter uri icon

abstract

  • This chapter uses software designed to measure river widths from satellite imagery to measure the widths of all rivers in the Yukon River Basin wider than ˜100 m from water masks derived from Landsat imagery. It also uses this data set to (a) understand the distribution of widths in the basin and (b) obtain the first uniform, high-resolution downstream hydraulic geometry (DHG) estimates for the entire basin and, separately, its major tributaries. The first step in calculating river widths for the Yukon Basin is to develop a mask differentiating water from all other land cover types. In order to develop DHG relationships between width and discharge, it is necessary to match each width measurement with an estimate of river discharge. The chapter concludes that the width-discharge relationship for the Yukon Basin developed with >500,000 data points is consistent with previous studies of DHG using many fewer observations.
