This paper examines why the definition of a river is an important and ongoing management issue, and outlines the development of legal definitions of river. Finally, the role of fluvial geomorphology is discussed with respect to the definition
of a river and its channel. This analysis will reveal whether the existing legislative framework adequately reflects the physical realities of rivers and watercourses so as to facilitate their conservation.

The purpose of this paper is to characterize the transport and storage of contaminants resulting from a dam-burst flood at a tailings pond near Church Rock, New Mexico. The method of explanation is to explore the spatial distribution and fluvial
dynamics of thorium in sediments of the Puerco River.

Une analyse statistique de l'altitude des formations alluviales de la NewRiver fait ressortir une variation de l'altitude moyenne de la haute terrasse au long de la rivière, qui est attribuée à la Néotectonique du Quaternaire supérieur. (CM).
New recognitions to genesis and exploitation of the Xuxi River in Jiangsu Province
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
of archaeological sites and excavated instruments; new discussion on the exploitation of the Xuxi River.

This research addresses 3 objectives : to provide a detailed description of the location, pattern characteristics and boundary conditions of wandering Miramichi rivers; to compare the pattern characteristics among wandering rivers within
the Miramichi basin and to other wandering, meandering and braided rivers; and to investigate formative processes for wandering Miramichi rivers. Wandering rivers within the Miramichi region occur in larger valleys located downstream of an abrupt change
in bedrock from resistive to more erosive bedrock lithology. Wandering Miramichi rivers may represent another anabranching river pattern type, different from anastomosed and previously described wandering rivers.
Stability, morphology and surface grain size patterns of channel bifurcation in gravel-cobble bedded anabranching rivers

This study presents a detailed field study of the morphology and bed sediment patterns of 5 channel bifurcations on the Renous River, New Brunswick, and a regional description of bifurcation angles within anabranching rivers in the Miramichi Basin
, New Brunswick. The stability of channels upstream of bifurcations and the location of bars at bifurcations influence bifurcation stability and the maintenance of river anabranching in the long term.
This paper is concerned with stream avulsion in terms of the channel morphology and the relative distribution of floodwater between the channel and the floodplain for the old and new courses especially as this affects stream power. On the example
of the Thomson River, the reliability of palaeochannel characteristics as indicators of environmental conditions is discussed.

The dynamics of river beds can be assessed from scour and fill data obtained from scour chains. Chain insertion, anchoring and relocation can be determined with minimal manpower by utilising a set of tested employment methodologies
. These are described in sufficient detail to allow fluvial geomorphologists, ecologists and river engineers to more commonly utilise chains in studies of river stability and river response.

Hong Kong's new industrial partnership with the Pearl River Delta in Spatial development in the Pearl River Delta.
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

Analyses the morphology and potential causes of arroyo activity in the Zuni River drainage basin. This study illustrates the linkage between arroyos and changes that occurred through time in local precipitation patterns. The results add support
Morphological characteristics of longitudinal profiles of rivers in the South Island, New Zealand

In this paper, morphological characteristics of longitudinal profiles of rivers are analyzed in relation to mathematical functions in the South Island of New Zealand, and their regional characteristics are examined in relation to geomorphological
settings. Fiordland is excluded from the study area because distinctly large rivers are not developed.
Geomorphic imprint of landslides on alpine river systems, southwest New Zealand
Classification ; Impact ; Landslide ; Mountain ; New Zealand ; South Island ; Stream ; Watershed
An inventory of 846 mass movements, mainly landslides, in 2 alpine regions of southwest New Zealand was created to explore the geomorphic impacts of slope-failure processes on river channels and valley floors. A nominal classification system
is introduced for characterizing : the physical contact nature between landslides and river channels; and the resulting geomorphic consequences for drainage. Dominant persistent geomorphic imprints of bedrock landslides include channel occlusions and landslide
Bedload transport processes in a braided gravel bed river model
Applied hydrology ; Carrying capacity ; Channel geometry ; Flow ; Fluvial processes ; Model ; New Zealand ; South Island
A 1:50 scale hydraulic model was designed, based on Froude number similarity and using hydrological and sediment data from a small braided gravel-bed river (the North Branch of the Ashburton River, Canterbury, New Zealand). The qualitative results
of the experiments using steady flows and unsteady flows reveal the nature of bedload transport (BLT) processes in braided rivers, particularly regarding variability of BLT in braided rivers.
