Australia ; Flow ; Irrigation ; Ontology ; Rivermanagement ; Rural life ; Stream ; Sustainable development ; Victoria ; Water management
The A. considers what it might be to do sustainable management through a case study of the Goulburn River in southern Australia. She attends to sustainable management as ontological work and tells of irrigation water and environmental water
as emergent in particular gathering of practices, technologies, and stories af rivermanagement and rural life. Ontological cleaving is performed. The paper contributes to the consideration of how ontological difference is managed and extends recent work

Sustaining river ecosystems : balancing use and protection
Biodiversity ; Concept ; Eastern Cape ; Ecosystem ; Habitat ; Hydraulic works ; River regime ; South Africa ; Stream ; Stream flow ; Sustainable development ; Water quality ; Water resources
This paper suggests methods for the sustainable operation of water resource use and protection. Environmental flows (EF) for rivers are used to illustrate some of the opportunities and problems inherent in managingrivers sustainably. In particular
has to be integrated to provide holistic levels of understanding if sustainable management is to be achieved. Case studies from South African river research over the past 20 years are used to illustrate the policies, methods, impediments and successes
of sustainable rivermanagement. In particular, a recognition of complexity and change, both in ecosystems and in human thinking and behaviour, is emphasized.
Managing the Missouri River basin : the failure of the Pick-Sloan program

Channel geometry ; Concept ; Fluvial hydrology ; Hydrosystem ; Rivermanagement ; Stream ; United States of America
Rivers are viewed here as hydrological entities, not geomorphic machines. The geomorphic work of the river (erosion, transport, deposition, etc.) – is a byproduct of the hydrological job of the river. The apparent steady-state equilibrium slope
adjustments of rivers are a byproduct of 4 basic phenomena: (1) hydraulic selection, which favors channels and branching networks over other flux patterns; (2) water flows along the available path of least resistance; (3) energy dissipation; and (4) finite
relaxation times. Recognizing converging trends of stream power or slope and sediment supply as common (but far from inevitable) side effects rather than self-regulation has important implications for interpreting and predicting fluvial systems, and for river
Channel adjustments, bedload transport and sediment sources in a gravel-bed river, Brenta River, Italy
Multi-scale characterization and evolution of channel forms in gravel-bed rivers
by a morphological approach, which allows the construction of a sediment budget. The results should be taken into account in addressing sediment management and restoration along a dynamic and unstable river such as the Brenta.
This paper deals with the Brenta River, a gravel-bed river strongly affected by human impact. The aims of this work are 1) to reconstruct the channel adjustments that have occurred during the last decades and 2) to analyse the present condition
of the river in terms of bedload transport and sediment sources. The study reach was investigated using historical maps, aerial photographs, monumented cross-sections, laser altimetry data and field survey. Bedload transport rates were estimated

Fluvial geomorphology of the Kupa River drainage basin, Croatia: A perspective of its application in rivermanagement and pollution studies
Channel geometry ; Croatia ; Environmental management ; Grain size distribution ; Human impact ; Pollution ; River bed ; Sediment transport ; Stream ; Stream flow
The AA. describe the geomorphology, tectonic setting, lithological framework and granulometric properties of the transboundary Kupa River basin. The generally meandering, east to west running course of the Kupa River starts from a karstic spring
in the mountainous region and flows down to the plains with braided channels. During the summer months, this potentially resourceful river is getting locally moribund and arrested within its course due to fall of river level and extremely uneven bed level
configuration along both transverse and longitudinal profiles of the river. Influx of pollutants and their restricted circulation in many places have led to severe eutrophication. Human interference has further caused modifications to the morphology
, morphodynamics and grain size characteristics of the river channel. Contamination from barite mine tailings, agriculture, industries and sewage waters has attained an alarming state on some stretches.
Traditional water management and state intervention: the case of Santo Antão, Cape Verde
Cape Verde ; Government intervention ; Irrigation ; Water ; Water management
A Sahelian-type climate and rugged relief in this westernmost island of the Cape Verde archipelago requires a meticulous water management to support its 45,000 people. The irrigation systems are intricate and well-organized, but a new irrigation
policy is advocated that involve greater farmer participation and creating the entire river basin as the natural unit of integration. - (DWG)
Construction of watershed flood disaster management information system and its application to the catastrophic flood of the Yangtze River in 1998
Watershed flood disaster management concerns monitoring and forecasting flood, assessing the flood damage and flood control and disaster reduction decision making in the scope of the whole watershed. Remote sensing and Geographical Information
System are powerful tools to construct Watershed Flood Disaster Management Information System (WFDMIS). In this paper, the design and implementation of WFDMIS are discussed. An application example in Poyang Lake Basin is given.
Channel adjustments and implications for rivermanagement and restoration
trajectory are or can be used in rivermanagement and restoration. The first part of the paper deals with channel adjustments and summarizes the results of recent studies carried out on twelve rivers in northern and central Italy. The second part illustrates
Most Italian rivers have experienced widespread channel adjustments over the last 100 years, mainly in response to a range of human activities. The aim of this paper is to show how knowledge of channel adjustment and reconstruction of evolutionary
An ecosystem approach for determining environmental water allocations in Australian dryland river systems : the role of geomorphology

ecological processes; hydrological analyses in which the key hydrological signatures of the river are identified and the impact of water resource development on these is determined; and the derivation of a water management decision tree that enables managers
A four-step process is presented involving : a hierarchical characterisation of the river system, to assess what mesohabitats are present and where they are located; the determination of flows that would inundate these habitats and perform other key
to allocate water to consumptive users during individual flood events. This ecosystem approach is outlined for the Condamine-Balonne River, a large dryland system in Australia.
