  • Tide-modulated hyperpycnal flows off the Huanghe (Yellow River) mouth, China
  • The paper describes hyperpycnal flows observed in situ off the Huanghe (Yellow River) mouth, their relationship to tidal cycles, and the mechanisms that drive them. Simultaneous observations at six mooring stations during a cruise off the Huanghe
  • mouth in the flood season of 1995 suggest that hyperpycnal flows observed at the river mouth are initiated by high concentrations of sediment input from river and modulated by tides. Hyperpycnal flows started near the end of ebb tides, when near-bottom
  • suspended sediment concentration (SSC) increased rapidly and salinity decreased drastically. The hyperpycnal flows have an important impact on both sediment dispersal and coastal morphology at the mouth of the Huanghe.

  • Morphological evolution of mouth bars on the Yangtze estuarine waterways in the last 100 years
  • In this paper the morphological evolution and mechanisms of mouth bar formation of the Yangtze estuarine waterways are studied by analyzing hundreds of years of historical data and the latest profile maps of some or the main mouth bar channels
  • in the Yangtze Estuary. According to the results (1915-2010), the AA. conclude that the evolution of the mouth bars differs depending on their location. In the North Branch it is directly related to large-scale reclamation in Chongming Island, but in the North
  • Passage it has a close relationship with regulation of the Yangtze Estuary Deepwater Channel. However, the evolution of mouth bars in the North Channel and South Passage is not only connected with the Yangtze Estuary Deepwater Channel Regulation Project

  • This paper examines the morphological development of the Yangtze River mouth, which has been diverting southeasterly (dextrally), according to historical (150 years) chart-based digital evolution model and on-site measured tidal flow data. The AA
  • . reveal a significantly narrowing of the northern river mouth branch due to rapid siltation. Their data have further demonstrated that the ebb flow that dominates in the study area changes its direction gradually from east to southeast. The AA. examine
  • whether the Coriolis Force could explain the dextral diversion of the ebb flow and the altered morphodynamical processes. The Coriolis Force causes an offset in propagation of in-out flow directions at the river mouth area to form a slack water setting

  • A suite of nine marine benches in the Alexandria karst area of the eastern Cape was found to extend from Kei Mouth to Cape St. Francis. The evidence was then related to that from earlier studies. The conclusion is reached that the suite of benches

  • River mouth bar formation, riverbed aggradation and channel migration in the modern Huanghe (Yellow) River delta, China
  • This paper addresses the recent (1970s-1990s) processes of river mouth bar formation riverbed aggradation and distributary migration in the Huanghe River mouth area, in the light of station-based monitoring, field measurements and remote sensing
  • interpretation. The results show that the morphological changes of the river mouth bar have been closely associated with the largely reduced fluvial discharge and sediment load. Landform development such as bar progradation occurred in 2 phases, before and after
  • 1989, which correspond to faster and lower bar growth rates, respectively. Furthermore, the history of river mouth bar formation reflects human impacts.
  • Coastal erosion in Northeast Ireland - Part I : sand beaches, dunes and river mouths

  • This study examines the effect of floods on the dynamic morphology of 7 of these river mouths between 1918 and 2005. The methodology is based on GIS techniques and utilizes over 300 aerial photographs from which detailed geomorphologic mapping
  • of river mouths and nearby geomorphologic elements was performed. River discharge records were incorporated into a database, permitting analysis of the effect of floods on the morphology of the river mouths. Based on their adjacent topography, 2 types
  • of mouths were recognized, each responding differently to river floods. In funnel topography mouths, flood morphology almost always displayed straight channels. In barrier-deflected mouths the response to floods is more complex.
