Business district ; Head office ; Honshu ; Japan ; Location ; Nagoya ; Offices ; Quaternary sector ; Tertiary sector ; Urban area
The purpose of this paper is to clarify the locational pattern and locational process of manufacturers' head offices giving due consideration to the relation between head office and plants. Manufacturer's head offices are divided into two locational
types, head offices which depend on their plants and head offices which are independent of plants. - (KA)
Automated recognition of valley heads from digital elevation models
An automated technique for recognizing valley heads from digital elevation models is presented. The technique has been developed for valley head recognition because valley heads are known locations of geomorphological activity and because areal
features have been largely ignored in the automated landform recognition literature. The problem of valley head recognition is divided into valley head location and valley head delineation, and the technique is developed using a DEM representing a simple
Channel head location and characteristics using digital elevation models
This study examines channel head position and characteristics in a catchment in Arnhem Land, Northern Territory, Australia. The aims of this study are to measure the area-slope attributes of channel heads in this catchment and to investigate to what
extent channel head location can be predicted by the area-slope relationship and the cumulative area distribution. The effect of digital elevation model grid resolution on the ability to locate channel head position and assess hillslope length will also

Gully-head morphology and implications for gully development on abandoned fields in a semi-arid environment, Sierra de Gata, southeast Spain
The AA. examine whether gully-head morphology can be used as an indicator for gully development and, hence, for sediment production. A survey was conducted at 5 hillslopes in the Sierra de Gata where different types of channel heads occur close
to each other. The survey included measurements of morphologic and pedologic properties, ground surface, channel and catchment characteristics of every gully head present (n=59). The analyses showed that it is possible to explain the evolution of gully
heads and the role of some controlling factors on the basis of their morphologies, at least for the gradual and the abrupt types.
Spatial distribution of gully head activity and sediment supply along an ephemeral channel in a Mediterranean environment
The AA. examine the factors that control the spatial distribution of bank gully heads along a reach of an ephemeral river (Rambla Salada) in an area threatened by desertification in Southeast Spain. The activity of 458 gully heads was assessed
in the field by pre-defined criteria. The results showed that land use and lithology have a significant impact on bank gully head activity. It was further investigated whether the gully heads were important sediment sources that contributed to reservoir

This paper reviews concepts in Germany to study Periglacial slope deposits (PSD) stratigraphy and describes the different PSD units encountered (Upper Head, Middle Head, Lower Head). The paper is relevant to the understanding of PSDs in other mid
-latitude regions. Classical and new results concerning the age of the PSDs show differences in the interpretation of Upper Head genesis. In terms of their ecological significance, case studies from eastern Bavaria illustrate the influence of PSDs

Les heads du Pléniglaciaire supérieur se caractérisent par la présence d'une matrice limoneuse abondante, d'origine éolienne, qui a permis la migration de blocs énormes vers la base des versants. Les apports éoliens sont discontinus durant les
autres phases froides du Weichselien, et la matrice des heads inférieurs provient surtout du remaniement de formations plus anciennes ou de la microgélifraction de roches préalablement altérées. Les grèzes litées se développent toujours au début des
cycles périglaciaires dans des milieux favorables tels que la base d'anciennes falaises marines où elles fossilisent de vieux sols ou des plages anciennes| elles sont fréquemment ravivées par les coulées de head.
Stream head migration : an indicator of runoff processes on chalklands
This paper describes the monitoring of chalk stream head migration in an area of southern England and discusses the observations in relation to water flow paths within the catchments. The processes described are of particular significance to water
Head and branch offices of big private enterprises in major cities of Japan
This article focuses on some aspect of economic management function performed by head and branch offices of big private enterprises located in the major cities of Japan, reviewing them from an historical perspective. (SGA).
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

Le matériel du head (en dehors de la fraction fine) peut s'obtenir avec un gel peu intense dans une répétition prolongée des cycles gel-dégel. Les conditions d'humidité sont plus difficiles à définir| toutefois il peut suffire d'une fonte de neige
ou d'un dégel superficiel du sol suivi de quelques cycles gel-dégel pour provoquer même en période à dominante sèche (éolienne) une gélifraction efficace (mais limitée dans le temps) fournissant blocaille et éclats dans un head à matrice loessique.
Gully-head erosion processes on a semi-arid valley floor in Kenya : a case study into temporal variation and sediment budgeting
A three year monitoring programme of gully-head retreat was established to assess the significance of sediment production in a drainage network that expanded rapidly by gully-head erosion on the low-angled alluvio-lacustrine Njemps Flats in semi
-arid Baringo District, Kenya. This paper discusses the factors controlling the large observed spatial and temporal variation in gully-head retreat rates. The selected gullies differed in planform and in runoff-contributing catchment area but soil
