Abstract Freshwater mussels are important functional components of aquatic ecosystems. Westralunio carteri is a threatened freshwater mussel species, endemic to south-western Australia, which has suffered recent, dramatic decline in range. The density, size structure and distribution adult this species within river reaches were investigated using quadrat searches modelled against range microhab...

Based on a two-step laboratory test including biodegradation and adsorption, it is possible to derive a prognosis of the behaviour of organic compounds during riverbank filtration and to prioritise the substances with regard to drinking water quality. It is shown for aromatic amines, used as an example of organics found in River Elbe water, Germany, how the simulation methods provide basic info...

There is still a lot of use the floodgates in main hole to drain residential water into river operated manually by someone charge opening and closing floodgates. It less efficient often happens operator, so overflows can lead flooding. In this final task, prototype an early flood detection system automation sewerage settlement located on riverbanks. The control works automatically according sig...

The research of structural masonry associated with geo-hydrological hazards in Cultural Heritage is a multidisciplinary issue, requiring consideration several aspects including the characterization used materials. On 25 May 2016, loss water from subterranean pipes and aqueduct caused an Arno riverbank failure damaging 100 m long portion historical embankment wall Lungarno Torrigiani Florence. w...

Introduction. Vietnam’s largest economic centre, Ho Chi Minh City, is facing riverbank erosion, one of the main causes which runoff. In this study, flow velocity field Saigon River section analyzed in different time periods. Materials and methods. Data on discharge, water level, river network topography channel were collected to set up simulation models programmes MIKE 11 21. These are tools us...

The largest economic center in Vietnam - Ho Chi Minh City, is facing increasingly serious riverbank erosion, one of the main reasons being flow. Therefore, this study, flow velocity field on Saigon River section accurately analyzed different time intervals with help MIKE 11 and 21 models. simulation results show that number velocities middle river 3-4 times greater than two banks. However, betw...
