alluvial sequences:Problems of dating and correlation  \nKarl W.Butzer  \nDepartments of Anthropology and Geography,  \nUniversity of Chicago  \n## Background\n\nGeomorphology as a discipline derives from the intellectual ferment of the earthsciences during the late eighteenth and early nineteenth centuries.Initially,geomorph-ology represented a qualitative and often deductive search to identify modern processesthat might serve to explain the origin of geological strata.It subsequently emerged as asubfield of geology and physical geography devoted to description and analysis oflandforms.The geological legacy has remained pervasive,not only in the persistentconcern with sequential events and related processes,but also through the many fieldprocedures,laboratory techniques,and general perspectives that geomorphologistscontinued to share with geologists in general.The long tradition of denudation cycles andstructural histories could be viewed as a counterpart to the geologists'interest inidentifying stratigraphic complexes.On a finer scale,the development of historicalgeomorphology (not to be confused with the approach of W.M.Davis)went hand inhand with refinements in glacial geology,as part of the increasingly diverse contributionsto an understanding of the Quaternary era.The most recent penchant for detailedmicro-studies,increasingly quantitative and inductive,is once again shared with a widerange of specialized earth science subfields.  \nThese links between geomorphology and the broader earth science tradition arelogical as well as indispensible,but they have also been detrimental in that this traditionhas generally been a conservative one.A half century elapsed between Charpentier andAgassiz on the one hand,and achievement of a majority view that Pleistocene glaciationhad been extensive on the other.Similarly,Wegener's hypothesis of continental drift wasderided for 50 years prior to the latter-day enthronement of plate tectonics.Geomor-phologists,in their turn,failed to respond to the challenge to integrate their research inthe evolving field of geography.They had almost no part in as logical an offshoot as soilscience,which consequently developed in response to agricultural interests.Acceleratedsoil erosion,a pre-eminently geomorphological problem,was ignored by geomorph-ologists until after World War II.Hydrology owes its origins to engineering interests,with geomorphologists still assuming the role of consumers rather than innovators.Thegreat upsurge of interest in environmental quality and management that began a decadeago found American geomorphology,on the whole,painfully unprepared to contribute aself-evident range of expertise.  \nKarl W.Butzer  \nThe conservatism of geomorphology is also apparent in the lagging development ofrealistic temporal frameworks.The persistent misconception that 'denudation chron-ology'can be equated with Davisian cycles 'dated'by landform geometries underscoresthe continuing ignorance of many geomorphologists as to what timescales really are.Thehistorical geomorphologist,in the strict sense,aspires to establish both relative andchronometric sequences of verifiable events.  \nThe perspective of relative scale is critical.'Polyglacialism'was firmly established byPenck and Brückner in 1911,in part on the basis of a complex sequence of glacio-fluvial'terraces'.A subsequent generation of geomorphologists simply assumed that alluvialunits corresponded to glacial-interglacial cycles.Functional floodplains were ascribed tothe sum total of ‘post-glacial’time,and most geological mapping services even nowcontinue to equate such floodplains with 'Holocene'.A complex suite of distinct‘post-glacial'environments had been demonstrated for temperate Europe on palyno-logical grounds,within a decade of Penck and Brückner's Alpine study.Yet geomorpho-logists chose to continue to work with the much coarser traditional timescales of theearth sciences.  \n## New Perspectives in Historical Geomorphology\n\nA revoluti","cbCaisepVrw041G8","https://ap.wps.com/l/cbCaisepVrw041G8","pdf",490461,12,"English","# Background\n## New Perspectives in
