Overgrowing of the water course with aquatic vegetation is a very common problem of surface streams, especially in flat areas and mainly in the growing season. Aquatic vegetation reduces the flow profile of watercourses, deforms the velocity profile, and thus also affects the transport processes in the surface streams. In addition, the surroundings of streams in the lowlands are often heavily farmed with the use of fertilizers, which results an increase in the concentration of nutrients in water what support the growth of aquatic vegetation. The content of the dissertation will be the quantification of the influence of aquatic vegetation on the flow conditions in the surface stream. The influence of nutrient content and temperature on the overgrowth rate of watercourse beds will also be analyzed and quantified. A prerequisite for the successful achievement of the goals is a thorough research of the current state of knowledge of the given issue, a theoretical analysis of possible methodological procedures, the performance of field measurements at a selected location using modern instrumentation, as well as the application of statistical analysis methods.
