Bankfull discharge determination using the new Invertebrate Bankfull Assessment Method
Along the paper the new method called Invertebrate Bankfull Assessment method (IBA method) of determination of bankfull discharge is presented. The investigation of bankfull discharge using IBA were performed within one Polish Carpathian stream in the mountain region: the Ochotnica Stream. As an index of bankfull the existence of certain species of invertebrates was used which are present and r...
متن کاملBankfull discharge and sediment transport in northwestern California
High-magnitude, low-frequency discharges are more responsible for transporting suspended sediment and forming channels in northwestern California than in previously studied areas. Bankfull discharge and the magnitude and frequency of suspended sediment discharge were determined at five gaging stations in northwestern California. Although discharges below which 50 percent of the suspended sedime...
متن کاملBankfull Discharge Recurrence Interval in Gravel-bed Rivers
Bankfull discharge was identified in some 30 gravel-bed rivers representing in total c. 40 gauging stations. The catchment sizes vary from 4km2 to nearly 2700km2. Bankfull discharge value increases with basin size. In the case of gravel-bed rivers developed on an impermeable substratum, the following equation emerges: Qb=0·087 A 1·044. Bankfull discharge recurrence interval was determined by fi...
متن کاملBankfull Discharge in Mountain Streams in the Cauca Region of Colombia
A flow considered effective or dominant in the process of stable channel forming, is the bankfull discharge associated to frequency between 1 and 2 years with an average of 1.5 year, according to Dunne and Leopold, 1978. Bankfull discharge or forming discharge is the flow which defines the morphological characteristics of the channel such as bars, meanders and curves. In this article, different...
متن کاملImpacts of land use conversion on bankfull discharge and mass wasting.
Mass wasting and channel incision are widespread in the Nemadji River watershed of eastern Minnesota and northwestern Wisconsin. While much of this is a natural response to glacial rebound, sediment coring and tree ring data suggest that land use has also influenced these erosional processes. We characterized land use, inventoried mass wasting, surveyed stream channels and collected discharge d...
