  • Suspended sediment load during floods in a small stream of the Dolomites (northeastern Italy)
  • Alps (The) ; Carrying capacity ; Discharge ; Flood ; Grain size distribution ; Italy ; Mountain ; Summer ; Suspended load ; Watershed ; Years 1990-99
  • Suspended sediment load was analyzed in a small, high-gradient stream of the Eastern Italian Alps which was instrumented to measure discharge and sediment transport. The ratio of suspended to total sediment yield and the relations between sediment
  • sources. An analysis of grain size has shown that erosion areas on hillslopes were the main sources of suspended load.
  • concentration and water discharge were analyzed for 7 floods which occurred from 1991 to 1996 in summer and autumn. Different patterns of hysteresis in relation between suspended sediment and discharge were related to types and locations of active sediment
  • Sediment yield and spurious correlation. Toward a better portrayal of the annual suspended-sediment load of rivers
  • Two alternative methods for portraying the annual suspended-sediment load of a river are suggested. One method consists of plotting supended-sediment load (tons per year) against distance downstream. Such plots indicate that annual suspended
  • -sediment load does not necessarily have a linear relationship with distance. The second method consists of plotting annual suspended-sediment load against drainage-basin area. Both methods more accurately portray fundamental relations between annual
  • sediment load and drainage-basin characteristics than does the yield-area relation because spurious correlation is avoided.

  • Dam ; Hurricane ; Precipitation ; Puerto Rico ; Rill wash ; Sediment transport ; Suspended load ; Watershed
  • The sediment data that were collected during Hurricane Hugo (five sediment stations and 11 rain gauges were operating in the Lago Loιza basin) presented an opportunity to quantify the transport of suspended-sediment loads into Lago Loιza
