The AA. investigated the Xuxi River drainage basin these years and got new proof for the parlance that the river was natural and altered artificially in a canal : location of the ancient Zhongjiang River; evidence from the distribution
and its water flows along an artificialcanal. The system of canal could be modified using the sustainable methods to restore some natural functions of a stream such as water retaining and self-purifying function. Groundwater and biodiversity would benefit
Artificial intelligence : realistic goals for the 1990s in Reflections and visions. 25 years of geography at Waterloo.
This paper is designed to stimulate discussion about artificial intelligence. Some illustrative applications in remote sensing are described, and one desideratum for artificial intelligence in geography is advanced.
over the last five decades due to the construction of artificial structures, such as embankments, multi-purpose dams, storing reservoirs, barrages, irrigation ditches and drainage canals. This report describes a recent transformation in flooding
and sedimentology. It is here interpreted as a silted-up artificialcanal with infill-deposits that indicate periods of shallow relatively quiet flow, periods of drying-out and occasional episodes of greater flow. The AA. suggest that it may well represent
This paper presents direct evidence in the form of a triangular cross-section channel (1 m in width 0.24 m in depth), for Late Neolithic artificial water management on the Tehran Plain. The antiquity of this channel is supported by dating directly
the earliest example of artificial water management in Iran.

numérisées permet d'identifier les plans de houle d'orientation NO-SE, responsables du transit sédimentaire O-E. Ce transit important, estimé à 800 000 m3 par an à l'ouest du canal de Vridi et à 400 000 m3 par an à l'est de ce même canal, contribue en grande
partie à l'ensablement du canal d'accès au port d'Abidjan. Les profils radiométriques obtenus permettent d'établir des corrélations entre les valeurs radiométriques et les caractéristiques granulométriques des sables : les sables grossiers et multimodaux
Intensive hydro technical works were conducted in the middle course of the Obra River (Poland) at the beginning of the nineteenth century. The natural river course (functioning before the major construction works) was transformed into 3 artificial
canals. Ground-penetrating radar investigations, ground-truthed with coring and remote sensing surveys, were conducted to reconstruct the course taken by the river prior to the hydro technical works. This work demonstrated that the Obra formerly had

The geomorphic impacts of artificial drainage in the form of railway culverts are examined on a steep hilsslope at Kwezana, Eastern Cape. An insight into the erosion and surface hydological conditions of the hillslope at pre- and post- railway
Dried earth layers of artificial forestland in the Loess Plateau of Shaanxi Province
By determining the earth moisture content of artificial forestland between 0 and 6 m deep in the Loess Plateau of Shaanxi province, the vertical change of moisture content, distribution and formation causes of a dried earth layer are researched
. The dried layers generally develop in middle-aged artificial forestland that consumed too much moisture.
This paper will firstly give an overview of peat drainage practice before reviewing the literature to show that artificial drainage of peatlands is unsustainable. It will then discuss the future needs for wetland research and peatland restoration
Relationship of eco-environmental change with natural erosion and artificially accelerated erosion
The Ziwuling forest area provides research base for tracing back eco-environmental change related to natural erosion and artificially accelerated erosion. Using methods of typical region investigations, in-situ experimental study and chemical
analysis of samples, impact of vegetation destruction and rehabilitation on soil erosion, characteristics of natural erosion under conditions of natural ecological balance and artificially accelerated erosion resulting from vegetation destruction in forest
area, and the processes of artificially accelerated erosion and soil degradation have been analyzed and discussed.
The use of artificial neural networks in a geographical information system for agricultural land-suitability assessment
The assessment methods which can currently be used with GISs have limitations which may lead to inaccurate assessment. An artificial neural network is an effective tool for pattern analysis. It allows decision rules of greater complexity
Artificial intelligence and its applicability to geographical problem solving
Artificial intelligence (AI) may be regarded as an attempt to understand the processes of perception and reasoning that undeslie successful problem-solving and to incorporate the results of this research in effective computer programs
