Abstract:

Nowadays, many countries are investing resources and efforts into developing new methods and models to achieve sustainable water management. There are many ways to realize this goal, and controlled drainage is considered to be one of the successful ways to conserve and protect water resources. Different types of control structures for application of controlled drainage were installed and tested in the Czech Republic in 1980’s, at various locations. Changes in political system in 1990’s also led to changes in management of the drainage systems, which in some cases resulted in improper maintenance. This thesis aims to contribute to an ongoing research in the field, by focusing on whether improper and insufficiently accurate use and maintenance of the controlled drainage systems, over a significant amount of time, can affect its overall functioning and feasibility. This is done by investigating the current hydropedological situation of a controlled drainage at Kolesa Vapno site (Pardubice region), and by mapping the measurable and verifiable changes that occurred in the past 30 years. The potential changes were observed through analysis of several parameters, such as water content (gravimetric and volumetric), particle density, saturated hydraulic conductivity (Auger hole method and KSAT) and particle size distribution (Hydrometer method).
