  • The job of the river
  • Channel geometry ; Concept ; Fluvial hydrology ; Hydrosystem ; River management ; Stream ; United States of America
  • Rivers are viewed here as hydrological entities, not geomorphic machines. The geomorphic work of the river (erosion, transport, deposition, etc.) – is a byproduct of the hydrological job of the river. The apparent steady-state equilibrium slope
  • adjustments of rivers are a byproduct of 4 basic phenomena: (1) hydraulic selection, which favors channels and branching networks over other flux patterns; (2) water flows along the available path of least resistance; (3) energy dissipation; and (4) finite
  • relaxation times. Recognizing converging trends of stream power or slope and sediment supply as common (but far from inevitable) side effects rather than self-regulation has important implications for interpreting and predicting fluvial systems, and for river

  • Braided channel ; Channel geometry ; China ; Discharge ; Discriminant analysis ; Meander ; Model ; River bed ; Stream
  • Based on data from 107 Chinese alluvial rivers, a study has been made to relate river channel patterns to the water discharge ratio (ζ) index. These rivers can be classified as four channel patterns, i. e., braided, low concentration meandering
  • , hyperconcentration meandering and island. It was found that, when mean annual water discharge (Q) is given, the ζ index for hyperconcentration meandering rivers is the highest, for braided rivers the second, for low-concentration meandering rivers the third
  • , and for island rivers the lowest. A discriminating model has been proposed for the above four channel patterns, based on the relationship between ζ and Q. Three threshold lines between the four channel patterns are well identified. Of the 107 Chinese rivers

  • River valleys as elements of the system of protected areas in the Lublin administrative district
  • This article presents results of the research on the protection of the river valleys of Lublin Voivodeship. To determine the degree of protection of the river valleys cartometric methods based on the available maps and the Ministry of Environment
  • and Office of Spatial Planning in Lublin data are used. The results of researches made that the protected landscape areas are element of the system of protected areas, which includes the highest percentage of river length in region (over 13%). Outside
  • the protected areas, there are 70% of the length of the river. In this system of protection, fragmentation of the valleys is significant. None of the major rivers of the region, including the Vistula and the Bug, is not protected throughout in their length

  • Hydraulic and geomorphological effects of run-of-river dams
  • As, in part related to public-safety concerns, the number of removals of run-of-river dams increases, it is crucial to understand the effects that these structures have on river geomorphology and sedimentology. This paper reviews current knowledge
  • related to the influence of run-of-river dams on the hydraulics and geomorphology of rivers and suggests types of studies that need to be undertaken to address gaps in current knowledge : numerical modeling and experimental investigations to determine

  • Sediment load and storage in the lower Yellow River during the late Holocene
  • This study determined sediment storage on the floodplains of the lower Yellow River in 5 historical periods after the year 602 BC mainly based on data of boreholes, radiocarbon dates in the Huang-Huai-Hai Plain and maps of historical changes
  • of the lower Yellow River channel. Furthermore, the mean annual sediment outputs from the upper and middle reaches of the Yellow River were calculated in the 5 periods through investigating the sediment delivery ratio of the lower Yellow River under different
  • conditions of artificial levees. The Loess Plateau is the principal sediment source of the Yellow River. The comparison of historical changes in sediment load of the lower Yellow River with those in the natural conditions and in human activities

  • Hydrotechnic structures on the Pomeranian rivers - A reaction to extreme hydrologic phenomena in the 19th century (in the example of the Upper Wieprza)
  • On the Pomeranian rivers the regulation works began in 1860 and led to a distinct shortening of riverbeds. It caused the aggravation of bottom erosion, and also lateral erosion. In the last few decades, the ending of work that interferes
  • with the riverbed has resulted in the general restoration of the primary character of Wieprza River bed. It is also mentioning that even when notable floods have appeared (1980), which where comparable to those that appeared at the end of 19th century, they did
  • not lead to any fundamental change to any section of the Wieprza River bed geosystem.

  • Geochemical tracing and spatial evolution of the sediment bed load of the Romaine River, Québec, Canada
  • In order to characterise the present river bed load sources, sediment transport and sedimentary connectivity, a study was conducted to document the compositional continuum of the lower 300 km portion of the river. Bed load samples were collected
  • Euclidean distance coefficients were also calculated between consecutive samples along the river revealing major bed load compositional breaks. These results indicate a longitudinal fractionation of the bed load along the 300 km course of the river
  • . This is further supported by the sedimentary budget calculated from the annual sedimentary input derived from erosion rates of the river banks, from sediment bed load measurements at 3 gauging stations and from calculated bed load transport capacity at these 3

  • The influence of sediment size, relative grain size and channel slope on initiation of sediment motion in boulder bed rivers. A lichenometric study
  • of flood events over the last 60 years is then calculated, and thresholds of sediment transport based on the sediment size are calculated. The results from the 4 studied rivers are compared to similar relationships in the literature. Sediment motion
  • thresholds appear to be very variable within the same type of river (mountainous boulder bed rivers). The critical specific stream power necessary to mobilize a particle of a given diameter may vary by up to 10 times from one river to the next. Bed sediment
  • size and river slope may explain this large range of stream powers.
