Analysis of the topologic configuration of the distributary patterns of twenty deltas using the approach of Smart and Moruzzi (1972). A similar analysis is performed on 13 randomly generated distributary nets. A comparison is made between
The typological diversity and the great number of parameters which are influencing the formation of deltas as well as their continuous change are being studied by many disciplines. The author endeavours to summarize the current stage of research

The Danube Delta is very large with diverse resources which have been intensively exploited during the modern period. It is now of great interest to conservationists with 280 species of birds. The origin of the delta is considered and its
development is traced from the initial offshore bar, referring to the writings of the classical scholars and other sources. Since the revolution of 1989, the intensive exploitation has stopped and the delta is now a Biosphere Reserve. The reserve is described
The effect of the Late Cenozoic tectonics (neotectonics) and their associated morphotectonics on the Nile Delta basin since the Late Miocene are discussed. The Nile Delta site seems to be affected by basement-related tectonics as it is located
deltas révèlent de faciès sédimentaires; un enregistrement sur un delta reflète un slump; et les enregistrements pour un autre delta indiquent l'épaisseur et les relations stratigraphiques de dépôts de tourbe.
The paper focuses attention on the new cooperation in industrial development between Hong Kong and the Pearl River Delta. Both secondary and first-hand delta have been used to portrait the extent, nature and spatial configuration of the relationship

The Sacramento-San Joaquin Delta is both an important environmental resource and a critical link in the water supply system for California. The aim of this paper is to analyze the time series of Delta inflow for evidence of trend and annual regime
changes. The emerging decadal changes in monthly inflows have practical ramifications for water managers in the Delta.
The AA. present a radiocarbon-dated pollen and sediment stratigraphy from a 52-m core collected from the Yangtze River delta. The data are interpreted in the context of climatic and vegetational changes, delta development, and sea-level history
of the Yangtze River delta region during the last 12,000 yr.

Sediment supply, depositional processus and the associated morphology and sedimentology of deltas in a fjord and several fjord lakes have been studied. The morphology of the deltas have been investigated by echo-sounding. Differences in downstream
sedimentation rates of the various deltas are related to dynamic and geometrical properties of the systems. The effect of different factors on delta morphology and sedimentology is discussed.

The ice content of near-surface permafrost was determined at more than 70 sites in the Mackenzie Delta. The principal objectives of this paper are : to describe near-surface ground-ice contents for different alluvial terrain types in the Mackenzie
Delta; to identify the factors that influence the development of near-surface ground ice; and to examine the influence of ground ice on the flooding hydrology of terrestrial environments in the Mackenzie Delta.
In this paper the most important geographical aspects of the evolution and development of the Danube Delta (Romania) are discussed, along with its geology, geomorphology, hydrology and land use pattern. Special attention is paid to the environmental
conflicts of the area, which arose after the political changes of 1989-90, when the delta became a nature conservation area, and thus subject of environmental protection. As a consequence a massive habitat reconstruction scheme of agricultural fields
Observations on delta-forming processes in a fjord-head delta, British Columbia, Canada in Sedimentology of fjords.

The Bella Coola delta is a laterally confined, steep-fronted, fjord-head delta in North Bentinck Arm in the Pacific Coast Mountains of British Columbia. The principal controls on sedimentation are: the high sediment yield and bedload dominance
of the Bella Coola River, which reflect climatic conditions and high drainage basin relief, river month processes, which are controlled by tidal stage and delta morphology: delta front deformational processes which are related primarily to oversteepening
in the upper delta front Wave processes are of limited significance.
The objectives of this study is to construct the Holocene eustatic curve at the Nile delta coast and to correlate this curve with the evolutionary events of Holocene transgression. The analysis is based on carbon dating of shallow-water deltaic
