“…These results accord with those of e.g. Cyberski (1973) who also stated that erosion proceeds for a longer time in the lower reaches of a reservoir. In this case, a considerable retreat, 1 and 0.6 m per 5 years, was recorded for the low banks at S2 16-21 years (1977-1981) after damming.…”

“…Such banks are k n w n to be subject to different rates of erosion (e.g. Cyberski 1973, Sundborg 1977, but nothing was previously known about their vegetational development. The study includes an analysis of the stability of the banks and their vegetation covers, and of the frequency, structure and diversity patterns of the vegetation over a period of five years.…”

Grelsson, G. 1986. Vegetational changes on two eroding banks of a short-term regulated river reservoir in northern Sweden. -Nord. J. Bot 5: 581-614. Copenhagen. ISSN 0107-055X.This study deals with the vegetational changes and the course of erosion on two types of river banks bordering a river reservoir, in northern Sweden. The water-level has been short-term regulated since 1961, with an amplitude of about 3 m in the uppermost reaches of the reservoir and about 1 m furthest downstream. The pattern of regulation includes both a weekly and a daily rhythm. The banks of the river reservoir have been cut in fine-grained sediments. The two sites selected for study were (1) a formerly littoral area (2) a formerly dry-land area. Percentage cover and number of shoots were determined annually within belt transects subdivided into 10 x 10 cm quadrats, during the period 1977-1981.The course of bank erosion was initiated and mainly continued by water movements. In the formerly littoral area, erosion proceeded only slowly, whereas in the formerly dry-land area erosion was rapid and the bank was continuously being undercut, leading to the formation of an overhanging mat of vegetation. As erosion progressed, this overhanging mat split up and slumped down into the reservoir. The vegetational changes on the overhang were considerable, while the terrace maintained a more stable vegetation cover. In the long-term, the composition of the vegetation on the former littoral river-bank remained more stable than on that cut into the former dry-land area. The break-up of the vegetation cover on the overhang also initiated secondary vegetational successions on the exposed soil. Considerable differences in the vegetation cover were also recorded from one year to the next. These differences were considered to be mainly due to differences in the rate and local course of erosion. Annual differences in the rhythm and/or amplitude of the fluctuations in waterlevel were considered to be less important in this respect.

“…In the context of fluctuating water levels, ice-scour adds a new and detrimental dimension to the erosional impact of reservoir shorelines and shallows (Newbury & McCullough, 1984;Kuusisto, 1985). The destructive impact of breaking waves in shorelines in newly incepted impoundments and reservoirs declines in its importances as shores are denuded of finer material (Kachugin, 1966;Kondrachev, 1966;Cyberski, 1973;Newbury & McCullough, 1984;Grelsson, 1986) and restabilization of the shore-lines takes place. However, the transient impact of the eroding processes could last for decades (Hecky & McCullough, 1984).…”

This paper launches concepts instrumental to environmental impact assessment (EIA) studies on hydropower schemes and lake regulations. Norwegian hydro-electric lakes (hydrolakes) and their environmental features are described, and evaluated against non-manipulated waters. A tentative classification of hydrolakes vs. natural waters is proposed. The need for a multiple approach to habitat classification is emphasized. Recommendations for future biological impact assessment approaches are suggested.Hydrolakes differ broadly from natural lakes by combining physical features not ordinarily co-occurring in non-manipulated water bodies. Storage type hydrolakes (reservoirs) feature winter draw-downs and enhancement of yearly level fluctuations; whereas other types of hydro-electric lakes have elevated water levels throughout winter. Hydrochemistry and optics of the studied hydrolakes exhibited no clear differences to non-impacted Norwegian inland waters. All lakes had signs of sublacustrine erosional activity related to internal waves and thermocline movements.

“…As more and more large dams have been constructed on mountainous rivers to satisfy the world's growing energy demand, bank erosion has become a major concern subsequent to the reservoir impoundment (Cyberski, 1973;Chai, 1996;Fu et al, 2010;Butt et al, 2011;Xu et al, 2013;Bao et al, 2015;Tang et al, 2016;Zhong et al, 2016;Su et al, 2017). Bank erosion, including landslide and bank collapse, occurs within the littoral zone of reservoir directly damage the hydraulic structures (Wang et al, 2007;Alimohammadlou et al, 2013).…”

The southwest alpine gorge region is the major state base of hydropower energy development in China and hence planned many cascading hydropower stations. After the reservoir impoundment, the intense water level fluctuations under the interaction of cascade dams operating and the mountainous flooding, usually cause bank collapse, landslide and debris flow hazards. The Xiaowan reservoir (XWR), for example, as the 'dragon head' meg reservoir located in the middle mainstream of Lancang River, have resulted in a series of geohazards during its building and operating. In this study, we investigated the number and surface area of collapses and landslides (CLs) occurred in the water level fluctuations zone (WLFZ) of XWR using remote sensing images of Gaofen-1 and Google Earth; evaluated the CLs susceptibility using information value method. The results presented that the total WLFZ area of 87.03 km 2 and 804 CLs masses with a total area of 1.98 km 2 were identified in the riparian zone of XWR. CLs mainly occurred at an elevation of 1190-1240 m, and the CLs density increased with an increase in altitude. The WLFZ with a slope gradient of 25°-45° is the main CLs distribution area that accounts for more than half of the total CLs area. The susceptibility assessment revealed that high and very high susceptibility zones are generally distributed along zones with an elevation of 1210-1240 m, a slope degree of 25°-45° and a slope aspect perpendicular to the direction of Lancang River. Furthermore, these susceptible zones are close in distance to the dam site and tend to be in the riparian zones with the formation lithology of Silurian strata. These results provide a valuable contribution to prevent and control geohazards in the XWR area. Moreover, this study offers a constructive sample of geohazards assessment in the riparian zone of large reservoirs throughout the mountains of southwest China.
