Influence of Reduction of Habitat Suitability Curves on Aquatic Habitat Suitability
Doláková, Gréta ; Macura, Viliam ; Škrinár, Andrej ; Čistý, Milan
Previous research into the aquatic monitoring of microhabitat fish preferences in Slovakia contains detailed valuable hydro-morphological, topographic, and ichthyological measurements for complex analysis. Consequent hydrological modeling of the database compares biotic parameters, represented by habitat suitability curves, and abiotic parameters of streams, to investigate the fish preferences of aquatic microhabitats. The research discusses an option if subsequent influence of reduction of habitat suitability curves on aquatic habitat suitability is justified to improve methodology of habitat assessment by regression model. The research creates an optimal regression relationship to determine the degree of habitat suitability curves reduction on mountain and piedmont streams in Slovakia.
Verification of effeciency of GAEC II measures on specific catchment using model based on SCS-CN.
HRDINA, Filip
The erosion is one of the biggest problems of today?s agriculture, more precisely of environment. At the time when 50% of the arable soil is threatened by the erosion, initiative of the erosion protection increases at the national and at the Europien level. The aim of this bachelor?s work is to evaluate the effectiveness of erosion controls which were issued within Good agricultural and environmental condition (GAEC 2) by the Europien Union. The ERCN program and HydroCad program are used as the modeling techniques, modeling the impact of the erosion measures in 4 scenarios. The modal area is the subcatchment P6 on the catchment of Kopaninský stream. The issues of the erosion, the erosion standard GAEC 2 and hydrological modeling using methods of CN-Curve Numbers are solved in the literature review.
