Summary Increasingly, river managers are turning from hard engineering solutions to ecologically based restoration activities in order improve degraded waterways. River projects aim maintain or increase ecosystem goods and services while protecting downstream coastal ecosystems. There is growing interest applying techniques solve environmental problems, yet little agreement exists on what constitutes a successful effort. We propose five criteria for measuring success, with emphasis an...
River restoration is at the forefront of applied hydrologic science. However, many river projects are conducted with minimal scientific context. We propose two themes around which a research agenda to advance basis for can be built. First, because natural variability an inherent feature all systems, we hypothesize that process more likely succeed than aimed fixed end point. Second, physical, chemical, and biological processes interconnected in complex ways across watersheds timescales,...

Conventional flood control has emphasized structural measures such as levees, reservoirs, and engineered channels—measures that typically simplify river channels cut them off from their floodplain, both with adverse environmental consequences. Structural tend to be rigid not easily adapted increased flooding regimes resulting change. Such actions also limit the natural hydrologic benefits of floodplains storing floodwaters, improving water quality, providing habitat for invertebrates fish...
Abstract River and stream restoration projects are increasingly numerous but rarely subjected to systematic post‐project evaluation. The few such evaluation studies conducted have indicated a high percentage of failures. Thus, (and dissemination results) is essential if the field river advance. Effective project success should include: (1) Clear objectives , identity potential incompatibilities among provide framework for design (2) Baseline data needed as an objective basis evaluating...
Abstract: Over the past 10 years Rosgen classification system and its associated methods of “natural channel design” have become synonymous to some with term “stream restoration” science fluvial geomorphology. Since mid 1990s, this approach has widely adopted by governmental agencies, particularly those funding restoration projects. The purposes article are present a critical review, highlight inconsistencies identify technical problems Rosgen’s stream restoration. This paper’s primary...
Among the most visually striking river restoration projects are those that involve creation of a new channel, often in alignment and generally with form dimensions different from preproject channel. These channel reconstruction have objective creating stable, single-thread, meandering even on rivers were not historically meandering, whose sediment load flow regime would be consistent such stable channels, or already sinuous channels bends symmetrical. Such specified by Rosgen classification...
Abstract River management based solely on physical science has proven to be unsustainable and unsuccessful, evidenced by the fact that problems this approach intended solve (e.g., flood hazards, water scarcity, channel instability) have not been solved long‐term deterioration in river environments reduced capacity of rivers continue meeting needs society. In response, there a paradigm shift over past few decades, towards restoration. But ecological, morphological, societal benefits...
In many countries of the Global South, aquatic ecosystems such as streams, rivers, lakes, and wetlands are severely impacted by several simultaneous environmental stressors, associated with accelerated urban development, extreme climate. However, this problem receives little attention. Applying a DPSIR approach (Drivers, Pressures, State, Impacts, Responses), we analyzed impacts their effects on hydrosystems (including stagnant waters), suggest possible solutions from series case studies...
Policy must address drivers, not just symptoms, of subsidence
Abstract Process-based restoration of fluvial systems removes human constraints on nature to promote ecological recovery. By freeing natural processes, a resilient ecosystem may be restored with minimal corrective intervention. However, there is lack meaningful design criteria allow designers evaluate whether project likely achieve process-based objectives. We describe four project's potential: the expansion process space and connectivity lost because alterations, use intrinsic energy do...
Abstract Understanding the impact of human‐made structures on groundwater levels is essential, with like dams or weirs presenting unique challenges and opportunities for study. The Baekje weir in South Korea presents an interesting case as has undergone full gate opening, which generally not reservoirs, providing valuable opportunity simulating removal conditions. main objectives are investigation level fluctuations under various operations, distances from weir, seasonal variations. study...
1. California is a tectonically active region with Mediterranean climate, resulting in extreme spatial and temporal variability river channel conditions. Restoration approaches that work one part of the state may not succeed elsewhere. 2. projects should be planned designed based on an understanding geomorphological ecological processes, rather than simply mimicry form, as blind application classification scheme. 3. Most rivers have been dammed, changed flow sediment transport conditions...
Two decades since calls for stream restoration projects to be scientifically assessed, most are still unevaluated, and conducted evaluations yield ambiguous results. Even after these of investigation, do we know how define measure success? We systematically reviewed 26 studies that used macroinvertebrate indicators assess the success habitat heterogeneity projects. All were previously included in two meta-analyses sought whether programs succeeding. By contrast, our review focuses on...
The Tonle Sap is the most fertile and diverse freshwater ecosystem in Southeast Asia, receiving nurturing water flows from Mekong its immediate basin. In addition to rapid development basin, climate change may threaten natural flow patterns that sustain diversity. impacts of on river 11 sub-basins contributing Lake were assessed using Soil Water Assessment Tool (SWAT) model quantify potential magnitude future hydrological alterations.

Dams are essential to society, yet have tremendous environmental impacts, for which there is an increasing interest in mitigation. At the same time, sedimentation threatens sustainability of reservoir storage and functions. We use term dam renovation encompass a wide range measures, including rehabilitation, commonly used structural retrofits, typically structure or spillway, fishway retrofits migratory fish passage, reoperation, involves modifying operations improve flow regimes ecological...
For millennia humans have extracted biological and physical resources from the planet to sustain societies enable development of technology infrastructure. Growth in human population changing consumption patterns increased footprint on ecosystems their biodiversity, including fresh waters. Freshwater biodiversity face many threats it is now widely accepted that we are a crisis. One means protecting restoring freshwater better manage exploitation biota aggregate (e.g., sand, gravel,...
Hydropower, although an attractive renewable energy source, can alter the flux of water, sediments, and biota, producing detrimental impacts in downstream regions. The Mekong River illustrates large dams limitations conventional dam regulating strategies. Even under most optimistic sluicing scenario, sediment load at Delta could only recover to 62.3 ± 8.2 million tonnes (1 = 10
