Abstract:
This paper discusses rapid flow and stage fluctuations in a large lowland river downstream from a large hydropower plant (HPP) in Lithuania. The main problem arises when the HPP is operating in peak mode. Such operation of HPP causes rapid flow and stage fluctuations, which can have a certain impact on river ecosystems. The study analyzes general abiotic indicators such as upramping and downramping rates and stage fluctuations downstream of the HPP. The main idea was to assess recorded stage upramping and downramping rates along the river downstream of large HPP. To assess stage fluctuation st

In this paper, field hydrological monitoring tests and an analytical solution for the aquifer response (i.e., the groundwater head) to stream-stage fluctuations are presented through a case study of the Yangtze River in Wuhan, China. A sinusoidal equation for the stream water level over time is proposed and is verified by the monitoring results. Based on the classical 1-D solution of ground water flow equations, a new flow model was proposed to analyze the confined aquifer response to stream-stage fluctuations. The groundwater head of the confined aquifer can then be calculated by embedding th

Abstract:
&lt;em&gt;Abstract.&lt;/em&gt;—Recent decades have seen substantial changes in fish assemblages in rivers of peninsular Florida. The most striking change has involved the addition of nonnative fishes, including taxa from Asia, Africa, and Central and South America. I review recent and historical records of fishes occurring in the Kissimmee River basin (7,800 km&lt;sup&gt;2&lt;/sup&gt;), a low-gradient drainage with 47 extant native fishes (one possibly the result of an early transplant), at least 7 foreign fishes (most of which are widely established), and a stocked hybrid. Kissimmee assemblages include fewer marine fishes than the nearby Peace and Caloosahatchee rivers, and fewer introduced foreign fishes than south Florida canals. Fish assemblages of the Kissimmee and other subtropical Florida rivers are dynamic, due to new introductions, range expansions of nonnative fishes already present, and periodic declines in nonnative fish populations during occasional harsh winters. The addition, dispersal, and abundance of nonnative fishes in the basin is linked to many factors, including habitat disturbance, a subtropical climate, and the fact that the basin is centrally located in a region where drainage boundaries are blurred and introductions of foreign fishes commonplace. The first appearance of foreign fishes in the basin coincided with the complete channelization of the Kissimmee River in the 1970s. Although not a causal factor, artificial waterways connecting the upper lakes and channelization of the Kissimmee River have facilitated dispersal. With one possible exception, there have been no basinwide losses of native fishes. When assessing change in peninsular Florida waters, extinction or extirpation of fishes appears to be a poor measure of impact. No endemic species are known from peninsular Florida (although some endemic subspecies have been noted). Most native freshwater fishes are themselves descended from recent invaders that reached the peninsula from the main continent. These invasions likely were associated with major fluctuations in sea level since the original mid-Oligocene emergence of the Florida Platform. As opportunistic invaders, most native freshwater fishes in peninsular Florida are resilient, widespread, and common. At this early stage, it is not possible to predict the long-term consequences caused by the introduction of foreign fishes. We know a few details about the unusual trophic roles and other aspects of the life histories of certain nonnatives. Still, the ecological outcome may take decades to unfold.

&lt;em&gt;Abstract&lt;/em&gt;.-Populations of Atlantic salmon &lt;em&gt;Salmo salar &lt;/em&gt;can be restored and enhanced through planting of green or eyed eggs (embryos) in rivers and by releasing fry, parr, smolts, or postsmolts. The success of the releases varies with time and site of release, broodstock origin, size and age of the fish, and rearing and release techniques applied. However, egg, fry or parr releases cannot be used for augmenting populations above the carrying capacity of the water course. To surpass the carrying capacity, the fish should be released as smolts or postsmolts. Smolts released in rivers during spring migrate to sea for feeding but return to the river of release for spawning. Atlantic salmon released at the postsmolt stage may return to the release site when adult, but thereafter, they may stray to any of a number of rivers for spawning. As a result of ecological interactions, released juvenile hatchery fish may partly displace, increase the mortality, and decrease the growth rate, adult size, reproductive output, biomass, and production of wild conspecifics through density-dependent mechanisms working in freshwater. Hatchery-reared Atlantic salmon are usually competitively inferior to wild conspecifics both during feeding and spawning in rivers, due to environmental impacts and genetic changes that occur during the juvenile rearing. Habitat restoration is preferred when restoring endangered, threatened, or weak populations. Degraded spawning habitats can be reconstructed, and poor freshwater quality can be mitigated. In regulated rivers, rapid fluctuations in water level should be avoided, and the migratory activity of the fish can be stimulated by increased water flow. Populations can also be enhanced by expanding the accessible nursery habitat by use of artificial fishways through human induced or natural migration hindrances. Adaptive management practice is useful when restoring and rehabilitating populations and habitats. More knowledge is needed about environmental and genetic influences on the phenotype of hatchery fish and how habitats constrain salmon production in rivers.

&lt;em&gt;Abstract.&lt;/em&gt;—The lower American River, located in Sacramento County, California, provides important habitat, a high-quality water source, a critical floodway, and a spectacular regional recreational parkway. It is also a key water source for the Central Valley Project, which provides irrigation water to 3 million acres of the country’s most productive agricultural lands. The river supports 43 species of native and nonnative fish, including fall-run Chinook salmon &lt;em&gt;Oncorhynchus tshawytscha &lt;/em&gt;and steelhead &lt;em&gt;O. mykiss&lt;/em&gt;. In the last decade, one quarter of all fall-run Chinook salmon produced in California’s Central Valley have come from the American River. The Sacramento region’s population is expected to double to more than 2 million people in the next 30 years. Water demand to meet population growth will cause additional stress on a river system that currently experiences low flow and high temperatures during critical salmonid spawning and rearing life stages. Increased demand for American River water outside the region will contribute to higher fall river water temperatures and more frequent fluctuating flows that result in stranding and/or isolation of fish. In 1993, regional stakeholders decided that new methods were needed to avoid water shortages, environmental degradation, groundwater contamination, and limits to economic prosperity. Consequently, they created the Water Forum. After 6 years of intense, interest-based negotiations, 40 stakeholder organizations approved the comprehensive Water Forum Agreement in 2000. The agreement allows the region to meet its needs in a balanced way through implementation of a comprehensive package of linked actions.
