Abstract: Highway engineers occasionally face the dilemma of either constructing a regular high bridge so that traffic would not be interrupted by floods or using a low water-crossing structure so that traffic would be interrupted ...

Abstract: The turbulent‐flow field above dunes is predicted with equations describing the transport of the kinetic energy of turbulence (k) its rate of dissipation (ε), and algebraic relations derived from a second‐moment turbulence ...

Abstract: The available information on incipient sediment motion criteria for both unidirectional and oscillating flow motions is summarized and analyzed according to the Shields diagram for incipient motion. The Shields diagram is ...

Abstract: The downstream dispersion of a sediment bed particle is represented by a stationary point process in space and time domains and plausible forms of the probability density functions of the particle step length and rest ...

Abstract: The theory of characteristics is applied to analyze two‐dimensional unsteady flow over a bed of fine sediment. The sediment is assumed to be so fine that suspension is the predominant mode of transport. An additional ...

Abstract: This paper presents a drought study of the Sacramento River of California considering the presence of reservoirs. A total of 508 years (1485–1992) of annual flow data are used. The data prior to 1872 was reconstructed from ...

Abstract: Droughts are stochastic in nature, therefore, statistical assessment of droughts is an attractive approach for water resources planning and management. In this study, a methodology of frequency and risk analysis of hydrologic ...
