Abstract

Predmet istraživanja ovog diplomskog rada je nesaturirana zona na području budućeg regionalnog vodocrpilišta Kosnica. Za potrebe istraživanja nesaturirane zone izvedena je pedološka jama u koju su instalirani tenziometri i TDR sonde. Za procjenu vrijednosti nesaturirane hidrauličke vodljivosti korišteni su terenski podaci o sadržaju vode i matričnom potencijalu. Analizirane su promjene tih dvaju parametara u 3 pedološka horizonta različite dubine. Na temelju podataka o granulometrijskom sastavu sedimenata procijenjene su vrijednosti hidrauličke vodljivosti s parametrima tla, s i bez volumne gustoće tla. Dobiveni podaci poslužili su za procjenu nesaturirane hidrauličke vodljivosti prema jednadžbi Van Genuchtena. Proračun nesaturirane hidrauličke vodljivosti i podaci o sadržaju vode omogućili su procjenu propusnosti nesaturirane zone u promatranom vremenskom razdoblju na istraživanoj lokaciji.

Abstract: The subject of this thesis is the unsaturated zone in the area of the regional well field Kosnica. For research of the unsaturated zone, a pedological burrow was digged in which Time domain reflectrometry (TDR) equipment and tensiometers were installed. To assess the value of unsaturated hydraulic conductivity, the field data on water content and matrix potential were used. Changes in these two parameters in 3 soil horizons with different depth were analyzed. Values of hydraulic conductivity with soil parameters, with and without bulk density of the soil, are based on the data of grain-size composition of the sediments. The resulting data were used to estimate unsaturated hydraulic conductivity using the equation of Van Genuchten. Calculation of unsaturated hydraulic conductivity and water content data enabled the estimation of hydraulic conductivity in the unsaturated zone in the reference period of the studied location.
