Evidence of stream response to Holocene climatic change in a small Wisconsin watershed
During the Holocene, moderate climatic and vegetational changes triggered several episodes of adjustment in the Brush Creek fluvial system. The alluvial chronology includes an episode of erosion at 7800-5700 yr B.P. corresponding to the mid-Holocene
precipitation minimum and an episode of floodplain construction at 5700-5000 yr B.P. corresponding to a rapid increase in precipitation. Holocene climatic changes have influenced the sedimentology of the alluvial deposits and soil development on them. Fluvial
adjustment is caused primarily by hydrologic and hydraulic changes related to climatic change, but there is no simple model for fluvial response to climatic change. The relationship between the direction of climatic change and the type of fluvial response

Natural and man-induced changes in the coastal environment in International symposium on coastal evolution in the Holocene.
The distinction between natural and man-induced changes in the coastal environment is to a considerable extent indeterminable. The PICG 200 should emphasize the mapping of distribution of advancing, stable and receding coastlines. One aspect which
invites joint consideration is the nature and scale of changes that will occur, both in coastline retreat and sea-level rise, if the modern global warming continues to such an extent that a major marine transgression occurs.
Differential Holocene sea level changes over the Globe: evidence for glacial eustasy, geoidal eustasy and crustal movements in International symposium on coastal evolution in the Holocene.
The sea level changes recorded are the endproduct of a complex interaction of different variables. The Holocene records give evidence of a general glacial eustatic rise, at least, up to 6000 BP, differential crustal movements and geoidal eustatic
changes that play the dominant role, at least, during the last 6000 years or so. Geoidal eustasy is on important factor.

It is proposed that interlocked variations of ice-sheet sinks in both polar hemispheres amplified and transmitted Milankovitch summer half-year insolation changes (a version of the astronomical theory) between 45 and 75 N into the globally

Separating Holocene tectonic movement from sea-level change in relative sea-level curves in International symposium on coastal evolution in the Holocene.
both show an exponential decay. The value of b in eache linear regression indicates insignificant eustatic sea-level change for the last 8000 years. Therefore the sea level deviation are neither eustatic nor isostatic and must be due to local tectonic
that changes in depth within the Bay of Fundy produce little effect on the tidal amplitudes, whereas such variations in water depth on George bank account for almost all the change. This calculation of tidal amplitude changes allows calibration of sea-level

Debris-flow deposits, dated by lichenometry, indicate that the majority of hillslope debris flows in Scotland have occurred within the last 500 years. Progressive weathering and climatic change can be discounted as the prime cause of the increase

The change in soil types observed at the eastern and western marginal regions of the core areas of the sub-Hercynian arid region is primarily due to a change in the substratum conditions. (HL).

En se basant sur les publications existantes, l'A. essaie de reconstituer du point de vue paléogéographique les changements dans les étendues et la localisation de la zone sèche au Sahara pour la période il y a 70-20 mille ans. Il cite des faits
bien datés qui témoignent du changement du climat. Grâce à cela il a pu reconstruire les anciennes frontières du Sahara établies à l'aide de la courbe annuelle isohyète de 200 mm. Les résultats présentés sont en partie hypothétiques, ce qui est dû au
