Major: Physical Geography, GIS. Below are two abstracts from
my recent papers.
- Oguchi, T., Jarvie, H. P. and Neal, C. (2000): River water
quality in the Humber Catchment: An introduction using GIS-based
mapping and analysis. The Science of the Total Environment,
251/252, 9-26.
The regional water quality of the Humber catchment was mapped
for key inorganic chemical determinands using a GIS system and
an extensive Environment Agency and LOIS monitoring database.
The resultant maps revealed the major factors affecting the
general characteristics of regional water quality. Sewage inputs
from industrial and domestic sources account for the high concentration
of many determinands in urban areas. The concentrations of particulate
components increase in tidal zones because of sediment trapping
and tidal re-suspension effects. Some determinands also exhibit
localized high concentrations related to coal mine drainage,
soil pollution caused by past ore mining, bedrock geology, the
agricultural use of fertilizers and the ingression of seawater
into the estuary.
- Oguchi, T. (2002): Geomorphology and GIS in Japan: background
and characteristics. GeoJournal, in press.
Japanese geomorphology has historically adopted methods and
concepts from research in western countries and applied them
to landforms in Japan and the flow of information has, in the
past, been very much unidirectional. This situation is becoming
more balanced, with increasing activity of Japanese geomorphologists
within the international research arena. Accordingly, many sub-fields
of geomorphology in Japan are now making important contributions
at the international scale. However, GIS applications in Japanese
geomorphology have been more limited, at a time of rapid expansion
of GIS in geomorphology within western countries. Although in
some countries, technical and financial limitations might inhibit
GIS popularization; this explanation cannot be applied to Japan,
given the high level of technological resources within the country.
It is suggested here that there are certain historical and cultural
aspects of Japanese society, which may have contributed to delayed
GIS propagation within Japan.
