  • Defining phases of bedload transport using piecewise regression
  • Carrying capacity ; Colorado ; Discharge ; Fluvial dynamics ; Grain size distribution ; Linear regression ; Model ; Stream ; United States of America ; Wyoming ; Years 1990-99
  • The aim of this paper is to demonstrate the best-fit functions between measured bedload and discharge and provide support for the selection of a two-piece linear regression model with a distinct breakpoint that can be bounded with confidence limits
  • by applying bootstrapping techniques. The AA. present and demonstrate the application of the piecewise regression procedure for transport rates measured at 8 sites on the Fraser Experimental Forest near Fraser, Colorado, where 100 to 200 samples were collected
  • between 1992 and 1997. The piecewise regression model is evaluated further using data from 4 streams in Colorado and Wyoming.

  • of landslide frequency with the physical parameters contibuting to the initiation of landslides on Lantau Island in Hong Kong. This GIS database is then used to obtain a logistic regression model for predicting slope instability. This model is then imported

  • in the lower Yellow River channel have been established. On this basis, a set of multiple-regression equations has been established that define the relationships between sedimentation in the lower Yellow River and the yearly or event-based runoff and sediment

  • A nonlinear dynamical model of landslide evolution
  • A nonlinear dynamical model for the evolution of landslide is proposed. The parameters of this model are obtained through an improved iterative algorithm of inversion developed in the paper. Based on the nonlinear dynamical model and nonlinear
  • dynamical systems (NDS) theory, the approaches to determining the Lyapunov exponents, the predictable timescale and the stability criterion of the evolutional state of landslide are given. A case study of the Xintan slope is presented to illustrate
  • the capability and merit of the nonlinear dynamic model.

  • of macrophyte growth on instream nutrient dynamics is discussed as an illustration of the potential for macrophytes to affect fluvial system functioning.

  • European integration and the spatial dynamics of manufacturing-employment change
  • Competitiveness ; Employment ; Europe ; European Union ; European integration ; Industrial branch ; Industry ; Job creation ; Location ; Shift-share analysis ; Spatial dynamics ; Specialization
  • This dynamics is examined in thirteen European Union countries between 1978 and 1996, mainly through the utilisation of shift-share techniques. The key finding is that the geography of manufacturing employment has remained almost intact

  • Computational fluid dynamics and the physical modelling of an upland urban river
  • This paper describes the application of a commercially available, three-dimensional computational fluid dynamic (CFD) model to simulate the flow structure in an upland river that is prone to flooding. Simulations use a rectangular channel geometry

  • Similarities and dissimilarities between the dynamics of sand and dust during wind erosion of loamy sandy soil
  • The AA. examine the aeolian dynamics of sand and dust during a wind erosion event on loamy sandy soil in Northern Germany. The large percentage of dust (up to 32%) in the topsoil and the high frequency of wind erosion events make the region suitable

  • Dynamics of secondary airflow and sediment transport over and in the lee of transverse dunes
  • Recent research literature on secondary airflow and sediment transport patterns over flow-transverse dunes is reviewed. Various issues surrounding the behaviour, modelling and sedimentological implications of near-surface airflow dynamics over dunes
