Hydraulic conductivity (KS) is a critical parameter used in soil and land research, essential for accurate hydrological modelling. This study endeavours to compare assessments of KS across designated sites near the Czech Republic - Poland border using a range of measurement techniques, with the aim of establishing their reliability and variability for modelling applications. The investigation spans the determination of permeability from grain size curves, KS estimation via field infiltration tests employing the do...

The article examines the effectiveness of measures to reduce flood risk in small watersheds in the Czech Republic. Currently, there is a search for integrated approaches that combine cost-effective erosion control measures (ECMs), in the form of organizational and agrotechnical changes, with more expensive technical measures (TMs) in the form of infiltration trenches and dry reservoirs. To achieve this goal, the critical drainage profile of a small village in the Olomouc region, at the interface between rural and ...

One of the most important properties of soils is soil texture. Soil texture is defined as a collection of soil particles of different sizes - i.e. grain size. Particle analysis is a laboratory process that causes material dislocation into individual particles. The methods for the actual soil grain size analyses are based on the standard. This is the sieving test, the density test or the pipetting method. These methods are well known and widely used. The soil is then usually classified according to the triangular d...

During development, flows are formed within the route and gradient conditions by trough-forming processes. Sensitive changes of the landscape and interventions in the water flows caused mainly in the last century in Czechia and the pressure of agricultural management are the cause of major changes in flows and more frequent occurrences of hydrological extremes. These phenomena cause problems in the form of migration permeability, higher pollution concentrations or higher water temperatures. The aim of the paper wa...

Damaging changes of landscape and interventions in the water cycle caused mainly in the last century in Czechia together with climate changes are the cause of more frequent occurrences of hydrological extremes. Recent years we have solved a lot of the drought related problem, but on the other hand, we cannot forget to the problem of extreme floods. For example, the recent regional floods in Czechia from 1997, 2002, 2009, 2010 and 2013 or the flash floods occurring every year. In these consequences developing metho...

In Czechia, climate change is already becoming a reality, and its consequences can be seen in the Czech countryside and landscape, but also in form of water shortages in water supply systems. In Hydrology, the most urgent problem is that the values of the long-term mean flows are decreasing in rivers as well as the yield of groundwater sources. One of the climate change adaptation measures is precise the reservoir capacity and reservoir operation policy in an uncertain condition. That means considered uncertainty ...
