  • Controls on bedrock channel incision along Nahal Paran, Israel
  • The purpose of this paper is to analyse the controls on knickpoint location and migration along the canyon of Nahal Paran in southern Israel. Nahal Paran contains several active and buried knickpoints, as well as an inner channel hypothesized
  • An evaluation of two ten-year sediment budgets, Nahal Yael, Israel
  • This paper compares a crude 10-year sediment budget published by Schick (1977) for Nahal Yael, a small hyper-arid drainage basin in the southern Negev Desert, with a second 10-year budget determined by more reliable methods. The comparison shows
  • The impact of wastewater flow on the channel bed morphology was evaluated in 4 ephemeral streams in Israel and the Palestinian Territories : Nahal Og, Nahal Kidron, Nahal Qeult and Nahal Hebron. Channel changes before, during and after the halting
  • Edaphic interslope and valley bottom differences at Evolution Canyon, lower Nahal Oren, Mount Carmel, Israel
  • The opposite slopes of lower Nahal Oren, Mount Carmel, designated Evolution Canyon display physical and biotic contrasts, although both are cut in Upper Cenomanian calcareous limestone. The three-fold greater solar radiation makes the south-facing
  • The palaeoflood record of a hyperarid catchment, Nahal Zin, Negev Desert, Israel
  • The palaeohydrology of Nahal Zin, a 1400 km2 catchment in the hyperarid Negev Desert, is inferred from slackwater deposits and palaeostage indicators in a canyon near its lower end. The palaeoflood record includes 28 floods over the last 2000 years
  • The Nahal Yatir Bedload Database: sediment dynamics in a gravel-bed ephemeral stream
  • The Nahal Yatir Bedload Transport Database arises from the Northern Negev River Sediment Monitoring Programme and represents the first body of bedload information to be collected during flash floods in desert gravel-bed streams. Bedload flux
  • Scaling the effects of riparian vegetation on cross-sectional characteristics of ephemeral mountain streams - a case study of Nahal Oren, Mt. Carmel, Israel
  • and spring of 2004 at Nahal Oren, Israel, an ephemeral mountainous stream. The AA. suggest that shrubs and trees may have a similar function in stabilizing banks via the root system, but the above-ground structure of these vegetative types has different

  • Channel bed-steps along Nahal Yael, Negev desert, Israel
  • The study was carried out in two ephemeral streams : Nahal Hebron and Nahal Og in the Negev and Judean Deserts. Magnetically-tagged pebbles and cobbles were traced after floods of low and intermediate magnitude. The data indicate that the mean
  • Formation and evacuation of a large gravel-bar deposited during a major flood in a Mediterranean ephemeral stream, Nahal Me'arot, NW Israel
  • Fluvio-pedogenic processes in an ephemeral stream channel, Nahal Yael, Southern Negev, Israel

  • les galets, détectées à une profondeur de 60 cm. Expérimentation dans le cours d'eau de Nahal Hebron (Israël).
  • The combination of the geomorphic parameters and the geological background enable expansion of the investigation of landscape evolution and suggest a model by detailing the evolution of 2 drainage systems in the central Negev-Nahal (wadi, dry
  • riverbed) Ramon and Nahal Neqarot. These 2 systems have largely shaped the Makhtesh Ramon. The study uses geomorphological methods to reconstruct the main stages of the region's post-Miocene landscape evolution and to characterize in further detail
