On the Holy Cross Mountains (southern Poland), located within the tectonic zone of the Trans-European Suture Zone (TESZ), numerous former quarries exist, including those of Cambrian quarzitic sandstones and sandstones with pyrite veins. This article presents the results of geochemical studies on the waters of the acidic mine pit lake Podwiśniówka (with an area of 1.5 ha and a maximum depth of 7.0 m) conducted in 2018. The tests were carried out in a vertical water column (every 1 m) in the central part of pit lake. The mean concentration of metals/metalloids, determined using inductively coupled plasma-quadrupole mass spectrometry (ICP-QMS), was found to form the following sequence in decreasing order: As> Cu> Ni> Co> Cr> Zn> U> Pb> Cd> Tl. With increasing depth, there was a general upwards trend in the concentrations of all the determined elements. In all cases, the average value of the single pollution index in the water column greatly exceeds the very strong level in relation to the geochemical background of surface waters globally (As – above 1250 times). The integrated pollution index for the ten trace elements in the water column increases with depth, and its average value exceeding 250 times the highest reference level. At the same time, the cluster analysis carried out showed the existence of two distinct depth zones in the pit lake: upper (0–4 m) and lower (5–7 m), differing in the scale of the water pollution.

The paper presents the possibilities of the airborne laser scanning (ALS) data use in the morphological analysis of the bottom of the designed Pietraszki multi-purpose water reservoir, which is located in the mouth section of the Sufraganiec river (5th rank) in Kielce. The source material consisted of 0.5 m resolution digital terrain model created by the MGGP Aero company on the base of ALS point cloud obtained in 2011. The analysis was performed in SAGA GIS software and included modelling of the Sufraaniec valley bottom, where the reservoir’s coastline was outlined, and a calculation of the reservoir’s geometrical and morphological parameters. A practical effect of the analysis was the estimation of the ground masses volume that need to be moved in the investment area and also the designation of recreational zones along the reservoir’s coastline. The performed analysis demonstrates the legitimacy of ALS digital terrain model use in detailed modelling of the planned reservoir bottom and also in outlining its coastline reach at the designed water levels.

W pracy zaprezentowano możliwości wykorzystania danych z lotniczego skanowania laserowego (ALS) do analizy morfologicznej czaszy projektowanego, wielozadaniowego zbiornika wodnego Pietraszki, zlokalizowanego u ujścia rzeki Sufraganiec (V rząd) w Kielcach. Materiał źródłowy stanowił numeryczny model terenu o strukturze GRID i wymiarze oczka siatki 0,5 m, opracowany przez firmę MGGP Aero na podstawie chmury punktów z nalotu wykonanego w 2011 r. Procedurę analityczną przeprowadzono z użyciem oprogramowania SAGA GIS, w którym dokonano modelowania dna doliny Sufragańca wyznaczając linię brzegową planowanego zbiornika wodnego, a następnie jego parametry geometryczne i morfologiczne. Efektem praktycznym tych prac, analiz i symulacji było określenie kubatury mas ziemnych przeznaczonych do przemieszczenia w obrębie projektowanego zbiornika w trakcie realizacji inwestycji, a także wydzielenie stref rekreacyjnego zagospodarowania jego brzegów. Wykazano zasadność zastosowania numerycznego modelu terenu, opracowanego na podstawie danych ALS, do szczegółowego modelowania linii brzegowej oraz rzeźby dna projektowanego zbiornika wodnego przy ustalonych dwóch poziomach piętrzenia.
