The purpose of this paper is volumetric quantification of soil erosion using the so-called erosion bridge. For the measurement, a locality in the South Moravian Region of the Czech Republic was chosen. With the erosion bridge, we can measure erosion rills. Rill erosion is caused by concentrated water flow. It occurs when runoff water forms small channels as it concentrates down a slope. The erosion bridge is a very simple device that enables us to accurately measure the shape of the soil surface in a given place. ...

The article discusses the efficiency of vertical subsurface flow filters in wastewater treatment wetlands, where the main filtration layer is composed of recycled aggregates. To determine the efficiency of the vertical filter using modified recycled aggregates, three test columns were created. The first column contained natural gravels, while the second and third columns used masonry (RMA) and concrete aggregates (RCA). The test filters were loaded with wastewater from a combined sewer system, with non-dissolved s...

Water is one of the basic necessities of life. However, water crises have become more frequent around the world as billions of people continue to suffer from a lack of access to clean water, sanitation and hygiene. Water is a limited resource that has been in growing demand - with the world's population increasing and water-intensive economic development continuing, infrastructure of many countries is not fit to meet accelerating demand. With climate change and its variability fluctuations in rainfall and extreme ...
