Problems in automated recognition of valley features from digital elevation models and a new method toward their resolution
Drainage network ; Greece ; Hydrology ; Landslide ; Model ; Numerical model ; Peloponnesus ; Valley
In this paper a new method for recognizing valley bottoms is presented. This is based on two improvements of Carroll's (1983) method, and produces a network that reflects the topography well. The network is used to locate valley heads. Once located
, the valley heads are delineated using criteria suggested by geomorphologists and hydrologists. The resultant valley heads are generally well recognized although two problems are evident : a) there are a number of commission errors; and b) the valley heads

Late Holocene valley-bottom aggradation and erosion in the South Loup River Valley, Nebraska
The chronology of aggradation and erosion is developed from ten radiocarbon ages. After discussing fluvial erosion and floodplain aggradation in the South Loup River Valley, the paper reconstructs the late Holocene alluvial records of the North
and Middle Loup River Valleys from published reports and articles.

Sediment transport in a proglacial valley, Sermilik, East Greenland
Climatic variation ; Cold area ; Glacial features ; Greenland ; Hydrology ; Model ; Sediment transport ; Valley
Detailed investigations of sediment transport have been carried out in a proglacial valley at the Mitdluagkat Glacier in East Greenland. The results from 1989, 1990 and 1991 have been compared with earlier measurements of sediment transport

There exist two systems of valleys. The subsequent system, based on a flat central ridge, disturbed the older, more extensive net of consequent valleys by numerous piracies. This development took place mainly during the Pleistocene. - (MS)

Shangri-La and Pakistan's Hunza river valley
Explores the reality behind the popular image of Shangri-La based on James Hilton's 1933 novel Lost Horizons. The A. contends that the Hunza valley is not the utopian place described in the book. The lure of the Hunza as Shangri-La has never been

The influence of rock mass strength on glacial valley cross-profile morphometry : a case study from the Southern Alps, New Zealand
Geomorphometry ; Glacial erosion ; Glacial features ; Model ; New Zealand ; Rocks ; South Island ; Valley
The purpose of this paper is to examine the model developed by Hirano and Aniya (1988, 1989, 1990) for the development of the glacial valley cross-profile, and to offer an alternative model using rock mass strength (RMS) and morphometric data
