Patterns of flow variability: consideration for river regulation and salmon management
… and inter annual flow variability in managing rivers for migratory salmonids. This study explores the degree of inter- and intra-annual flow variability at different spatial and temporal scales across the UK, using a novel approach to analysing natural variations in flow regimes. Principle …

The interacting hydrologic responses to changing climate, watershed physical characteristics, river regulation, and land development in the northeastern United States
… no development, and extensive development and riverine impoundments of the Merrimack River watershed. The Merrimack (New Hampshire-Massachusetts) is a 13,000 km2 forested (67%) watershed located in the northeastern United States. The overarching goal of this dissertation was to assess …

Status and Distribution of Fishes in Tributaries of the Garrison Reach of the Missouri River, North Dakota
<p>River regulation has altered the structure and dynamics of many riverine ecosystems, most notably through construction of large dams. Much is known about downstream consequences of river regulation. Recently, studies have examined the upstream influence of river regulation because conservation …

Seasonal fish community and reproductive biology of fishes in two tributaries of the lower Missouri River, USA
… rearing and feeding of fish in connected river systems. Regulation of rivers may alter the fish communities and environmental variables triggering fish use. Habitat destruction from dam construction is one of the leading causes for the decline of aquatic species, including big-river …

Incorporação da incerteza paramétrica na geração de séries sintéticas de vazões através de reamostragem
… models are very useful in simulation studies of river regulation. However there is always an uncertainty in their parameters due to fact that time period of the streamflow records are always short. The Bayesian and Classic methods for consideration of parameter uncertainty show many dependence on …

Plant Community Invasibility in Riparian Landscapes: Role of Disturbance, Geomorphology, and Life History Traits
… ecology of non-native, invasive riparian plants, river regulation, and the potential for restoration. For chapters one and two, I researched different aspects of the <italic>Tamarix</italic> invasion along the Colorado River through the Grand Canyon. Tree-ring analyses and surveys for …

Freshwater inflows to estuaries : organic carbon and microbial food webs in south-east Australia
… estuarine processes and productivity. River regulation and extraction have greatly reduced FWI to estuaries. Little attention has been paid to the role FWI has in delivering organic carbon to estuaries. The aim of this thesis was to define the relationship between freshwater inflows, …

The platypus : historical, ecological, and behavioural advances to improve the conservation of an elusive species
… overlapping Australia’s most regulated rivers, the impacts of dams remains relatively unstudied. In my thesis, I aimed to address specific knowledge gaps for platypuses, assessing potential past and present distribution, the impact of dams, and their movement behaviours. Chapter one …

Efficacy of Riparian Revegetation Projects in the Inland Pacific Northwest
… damaged by the combined impacts of grazing, river regulation, development and other types of land use, so that many no longer provide key ecosystem functions and services. Revegetation is a common riparian restoration practice, but there is little information available on whether revegetation …

Reservoir compensation releases and the ecology of the River Derwent, Northumberland.
River regulation is commonplace in England and much of the UK. Regulation for the purposes of public water supply causes flows downstream of a reservoir to be attenuated and the flow regime of the channel to be altered. The impact of channel impoundment on a small, upland UK river, has been …

ECOTOXICOLOGICAL IMPACTS OF RUN-OF-RIVER DAMS ON THE AMERICAN DIPPER (CINCLUS MEXICANUS) AND MOUNTAIN STREAM FOOD WEBS
Run-of-river (RoR) hydroelectric dams are an increasingly common alternate energy source on mountain streams. Despite reductions in size and greenhouse gas emissions compared to conventional impoundments, RoR dams may have ecotoxicological impacts through disruption of the natural flow regime. The …

Factors affecting the recruitment of riparian vegetation on the Ord and Blackwood Rivers in Western Australia
… life history traits of particular species in a river in the cool temperate zone of south western Australia (Blackwood River) and on a river in the dry tropics of the Kimberley region of north-western Australia (Ord River). By studying two contrasting river systems in different climatic zones, …
