SoWa

The SoWa (Soil&Water) Research Infrastructure is the infrastructure for comprehensive interdisciplinary research of interactions between soil and water ecosystems, ecosystem processes and services on various spatiotemporal scales in the context of sustainable landscape use. It consists of four research sections (RS), six research programmes (RP) and nine highly equipped laboratories driven by ten highly experienced […]

Cyanobacteria – a hidden threat

Almost everyone certainly met with the Cyanobacteria outbreak in ponds and natural pools; however, in recent years it is nothing unusual in water reservoirs used as drinking water sources as well, which causes a plenty of difficulties to water treatment plants. The problem is usually not the cyanobacteria themselves but rather the substances they produce […]

Vortices around us

Vortical structures (shortly: vortices) virtually surround us in a normal life. However, we usually do not perceive them as vortices unless somehow visualized, even in the case of dynamic effect on us. We cannot even exclude their local presence in our respiratory or cardiovascular system. A number of vortices relate to human activities, engineering, technological […]

Flash floods

A number of municipalities in the Czech Republic are situated in areas with a significant flood risk. Municipalities in the foothills and mountain areas are especially affected by flash floods. Every year there are 60–100 flash floods in the Czech Republic, some of them with disastrous consequences. They occur exclusively during the summer, usually when […]

Nanofibres

Nanofibers are characterized by high specific surface area due to very tiny diameter from tens nanometer to micrometer. Thanks to this properties the nanofibers layers are employed in technical applications (filters, sensors, separators in battery) and also in medical applications (preparation of replacement organs, vascular transplants, target drugs delivery). The prior material for preparation of […]

Water in landscape

Water cycle is one of the fundamental energy and matter transfer mechanisms influencing the human society in numerous ways. The knowledge of the underlying processes behind this cycle is a key issue to the sustainable water management. Water resources are nowadays (probably more than ever) influenced by human activities and ongoing climate change. Floods and […]

Plastic processing

Although plastics are an integral part of our everyday life, few people realize how a production of individuals plastics products, such as PET bottles, plastic bags, car interior parts, is complicated. At first, it is necessary to choose or to produce a material (polymer) with proper physico-chemical properties (e.g. resistance to mechanical wear, UV radiation, […]

Microplastics in water

Recently, the presence of plastics in water environment has gained considerable attention. Not only plastic litter that is visible to the naked eye, but also smaller debris – recognized as microplastics – are of a great interest. Microplastics (MPs; plastic particles smaller than 5 mm) have been detected in different water bodies, i.e. oceans, seas […]

Fluid mechanics

With the transport of bulk materials in the form of a two-phase suspension (liquid-solid phase) we can meet in a number of industries - chemical, food, mining, energy and many others. In addition to closed pipe systems, which are usually hidden for ordinary citizens in industrial agglomerations, the two-phase flow is part of river systems […]
