“…Dams can be classified as rigid dams when they are constructed using stiff materials such as masonry [45], steel [46], concrete [47], rubber [48], and timber [49]. Non-rigid dams are dams constructed from relatively less stiff materials and can easily be deformed when exposed to water effects and other forces.…”

Dam and powerhouse operation sustainability is a major concern from the hydraulic engineering perspective. Powerhouse operation is one of the main sources of vibrations in the dam structure and hydropower plant; thus, the evaluation of turbine performance at different water pressures is important for determining the sustainability of the dam body. Draft tube turbines run under high pressure and suffer from connection problems, such as vibrations and pressure fluctuation. Reducing the pressure fluctuation and minimizing the principal stress caused by undesired components of water in the draft tube turbine are ongoing problems that must be resolved. Here, we conducted a comprehensive review of studies performed on dams, powerhouses, and turbine vibration, focusing on the vibration of two turbine units: Kaplan and Francis turbine units. The survey covered several aspects of dam types (e.g., rock and concrete dams), powerhouse analysis, turbine vibrations, and the relationship between dam and hydropower plant sustainability and operation. The current review covers the related research on the fluid mechanism in turbine units of hydropower plants, providing a perspective on better control of vibrations. Thus, the risks and failures can be better managed and reduced, which in turn will reduce hydropower plant operation costs and simultaneously increase the economical sustainability. Several research gaps were found, and the literature was assessed to provide more insightful details on the studies surveyed. Numerous future research directions are recommended.

La disponibilidad del agua es tan prioritaria para el desarrollo de la vida del ser humano, a diferencia de otros recursos al agua no se le conoce un sustituto, [1]. Para el 2050 una de cada tres personas probablemente desarrolle su vida en un país afectado por la escases hídrica de agua dulce [2].…”

The Chilintomo irrigation system serves an area of 2000 ha and has been in operation since the 1970s. The diversion structure worked with a dam with planks, which were placed when the winter season ended to take advantage of the low water flows. In 2016 the structure was "repowered" by implementing a 3 m concrete dam; however, this has caused problems with flooding upstream of it. This research aims to cover the use of inflatable dams in agriculture, analyzing the case study of the Chilintomo River -Ecuador, which allows the free passage of maximum flows in the rainy season and in turn allows controlling the levels in the channel in dry season, The methodological process contemplated the collection of meteorological and cartographic data, information processing, modeling and design proposal, in order to establish a runoff rain model using HEC -HMS, analysis and results of the hydraulic model with two scenarios of the inflatable gate. The results obtained from the modeling show that the structure allows to mitigate the floods that produce the maximum flows for the low return periods, and in dry season it will be able to divert the flows towards the irrigation channels of the system. The implementation of agri-food systems is part of the 17 Sustainable Development Goals (SDG) (1, 2, 9, 15, 16 and 17), proposed by the United Nations (UN) in 2015.

“…Based on its low investment, simple structure and nonresistance to water, rubber dam has found wide application in many countries around the world (Chanson, 1998; Jena et al, 2015; Tam & Zhang, 1999). With increasing demands of urban river regulation, numerous cascade rubber dams have been constructed in rivers in China (Rane, Thakur, & Thakur, 2019). As the small dams are manifested to produce a negative effect on river systems, however, the knowledge about small rubber dams' impacts on dammed rivers is incomplete (Bao, Li, & Su, 2020).…”

Aquatic ecosystem response to dam construction and operation is an important concern, but systematic assessment of impacts induced by cascade small rubber dams are seriously lacking. In this study, the Huangshui River in Qinghai Province was selected to investigate biological response to small cascade rubber dams. Two years of monitoring data in 2018 and 2019 were utilized to quantify the variation of five kinds of aquatic organisms. Results indicate continuous rubber dams produced significant changes to hydrological regimes of rivers, especially for high flow seasons, and further affect aquatic biological populations and structures of the river. (a) The biodiversity and biomass of plankton increased by 8.0 times and 1.8 times, respectively; the biomass of fish and benthic animals were enhanced by 3.2 and 2.1 times, respectively, but the species richness decreased by 30% on average. Native fish are completely replaced by exotic fish, and benthic animals are changing towards singularity; (b) The surface and bottom food chains of the river gradually become dominant, and the disappearance of native fish in the middle layer caused the exchange flow in the middle layer to decrease rapidly, which leads to a dumbbell‐shaped distribution structure of biomass; (c) The regulation services of rivers have also undergone huge changes. N2O and CH4 emissions from dammed areas have increased by 10.1 times, and the water purification function varied in different dammed areas.
