The littoral zone is one of the most complex geomorphic systems subject to many geomorphological factors, including waves, sediment supply, climate sea levels and tectonics.

Though climaticgeomorphology has long been perceived as providing a realistic framework for landform analysis, only the arid , nival and glacial systems and some constructional forms on the coast are readily identified in the landscape, present
and past, as climatically zonal in character. Various landforms are shaped by processes and mechanisms which, though climatically generated, vary genetically, and are active in a wide range of conventionally delineated climatic regions. They transgress
This paper represents the first attempt to divide the surface geomorphology of Kuwait into four major geomorphic zones: a) the coastal zone; b) the wadis and ridges zone; c) the lowland zone; and d) the dune fields zone. Tectonics as well as climate
changes play a major role in the distribution and evolution of land form features. Paleosols and fresh water aquifers reflect wetter climate.
The article is an overview of Bulla's theory of climaticgeomorphology, focusing on the system of climaticgeomorphologic zones. Climatic conditions of rill, gully and river erosion were analysed within the framework of this system. - (AM)
Landforms and Quaternary climatic change in The geomorphology of Southern Africa.
The review article examines the evidence for environmental change in the geomorphological features of southern Africa and examines the nature and chronology of those changes in the Quaternary.
Climatic and non-climatic controls of aridity : the case of the northern Negev of Israel in Arid and semi-arid environments. Geomorphological and pedological aspects.
A research project presently being carried out in the northern Negev is described, and tentative models are offered as a means of correlating and arid/semiarid ecosystem to climatic and non-climatic environmental controls.

The A. summarizes the effects of climatic changes in the past, indicates the different types of man-induced climatic changes and discusses the (potential) effects of these changes on the worldwide average sea-level. Thereafter a summary
of the progress in geomorphological survey and mapping is presented with The Netherlands serving as an example. Finally some remarks are made on useful geomorphological data : survey and mapping can contribute in encountering the problems caused by sea-level rise
South African geomorphology : critical choices for the future
Bibliographic analysis ; Climaticgeomorphology ; Congress ; Earth surface processes ; Geomorphology ; Research ; Soil erosion ; South Africa ; Twentieth Century
The trends in southern African geomorphology, based on a review of some 1500 journal articles and 11 conference proceedings from both the local Geomorphology Association and Geography Society are reviewed. They are contrasted with developments
within the discipline as a whole represented by more than 3000 abstracts in the proceedings of international congresses on geomorphology between 1985 and 2000 . - (AJC)

While impacts of climate change at the coast are often primarily viewed in terms of landform adjustments to accelerated sea-level rise, geomorphologists are also starting to unlock the subtleties of how coastal processes are forced by a broader

Geomorphological evidence for late Holocene climatic change in northern Australia
Aeolian features ; Australia ; C 14 dating ; Chronostratigraphy ; Climatic variation ; Dune ; Fluvial processes ; Holocene ; Northern Territory ; Palynology ; Quaternary ; Queensland ; Thermoluminescence
The hypothesis that the late Holocene climate of northern Australia has been characterised by periods of reduced rainfall has been examined by constructing a detailed chronostratigraphy of climatically sensitive geomorphological sites, in particular

Five sections with different types of interaction between tectonic movement, relief, and climate can be distinguished on the western slope of the Andes : in all sections apart from the driest, a growing height increased erosion and denudation

With such a limited area and range of rock type, Malta cannot provide anything approaching a representative sample of the landforms which occur in the Mediterranean Basin. However, few geomorphological features can be considered unique
to the Mediterranean, since they are shared either by the more humid temperate climates to the north or the semi-arid regions to the south and east. The wied, a hybrid between the humid temperate and semi-arid climates, might be considered a truly Mediterranean
landform and is the predominant feature in maltese geomorphology.
A review of recent geomorphological contributions studying environmental changes in deserts. In particular, it can not be ignored that geomorphologists are able to make valuable inputs to the study and understanding of recent changes in desert
conditions, whether induced by climatic pertubations or human actions, and even in cases where the causes remain in doubt.
Climate variations and the Appalachians from the Late Paleozoic to the Present : results from model simulations in Appalachian geomorphology.
A series of climate model simulations are utilized to examine the climate evolution of the Appalachians from the Carboniferous to the Present through consideration of large scale changes in paleogeography and potential variations in carbon dioxide

The natural forces that influence the geomorphology of the Wadden Sea area are wind and climatic factors, the tides and biological factors. Although the Wadden Sea as a whole and in the long run is a rather stable environment, local conditions can
It is suggested that the global sustainability debate would benefit from more active participation by geomorphologists and that geomorphology would itself benefit by embracing sustainable development research more explicitly. Agenda 21's action
programs, comprising 40 priority research areas, is seen to require geomorphological expertise; it is also argued that solutions to the identified problems can only be anticipated through interdisciplinary collaboration.
