In this note, the AA. discuss the chronology of single leaf pinyon remains from Danger Cave, western Bonneville Basin, and their biogeographical implications.

This study determines the spatial and temporal variability of in-channel storage within a small semiarid drainage basin in equatorial East Africa, and establishes a tentative sediment budget for coarse (> 200 m) in-channel sediments, over one runoff
Autogenic and allogenic denudation in carbonate karst by the multiple basin method : an example from Svartisen, north Norway
When choosing small basins that are subsets of each other, assumptions of hydrologic and lithologic uniformity may be satisfied. Then the autogenic and allogenic components of the denudation may be calculated by a linear model of uniform mixing
Etude, en période de crue et en période de sécheresse, du comportement hydrologique de 2 petits bassins situés sur le rebord septentrional des Hautes-Fagnes, l'un couvert d'une lande installée sur un substrat tourbeux épais et l'autre dans une
Geomorphology and pedogenic evolution of Quaternary calcretes in the northern Adana Basin of southern Turkey
Etude de la situation géomorphologique des calcrètes et des horizons columnaires par rapport aux sols dans le nord du Bassin d'Adana. Les calcrètes et les horizons à colonnes témoignent des fluctuations climatiques pléistocènes. Présentation d'une

of data have been used in the analyses : 1) a study in small plots and basins in the Verkaa research basin, about 35 km north of Stockholm, and 2) the nationwide network for the measurement of transport of sediment and dissolved material.

objectives : 1) estimate the seasonal variations in water quality| 2) evaluate the nature of spatial variations in the stream solute load within the basin to indicate its sources| 3) use the results to evaluate the magnitude and significance of chemical
denudation in the parts of the basin which provide most of the streamflow, as well as the system as a whole.
lithostratigraphic framework is proposed. The provenance of the sediments was established by heavy mineral and gravel analysis. Rhine, Meuse and rivers from the Scheldt basin contributed their sediments to the southern North Sea basin during different stages
of the Early-Pleistocene. The major importance of the rivers from the Scheldt basin in the upbuilding of the sedimentary sequence is emphasized.
A study is made of temporal and spatial variations in material concentrations and transport in connection with spring and summer quick flow periods and episodes in a small drainage basin, Koiransuolenoja, of size 6.75 km2. More long-term variations
