This article presents hydrological aspects of a renaturization plan for a river valley that has been significantly transformed as a result of human impact. A section of the Szarlejka River valley located at the border of the cities of Bytom and Radzionków was used for this purpose. The hydrographic conditions of the area under consideration have been significantly altered due to human action. These transformations are the result of systematic residential and industrial infrastructure development, which has been accompanied by industrial waste disposal. Underground coal mining in the area has caused subsidence and discharge of saline mining waters to rivers. The Szarlejka is considered one of the most polluted rivers in Silesia Province (Polish: województwo śląskie) and all of Poland. The primary objective of the renaturization plan is to improve abiotic conditions and water status. This plan is based on the analysis of all accessible data, including archival maps and field work. Hydrological and hydrotechnical renaturization actions are proposed for the Szarlejka River valley that cover the elements, structures, and facilities, of which the mere presence brings the waters closer to their natural state (barrages inhibiting erosion, connections allowing for the circulation of aquatic organisms). The proposal also includes building astatic reservoirs, creating oxbow tanks in retained sections of the old river bed, and building a pond with a wetland and an island. The restored structures will affect abiotic and biotic conditions, consequently influencing the water recovery process with the aim of bringing it closer to its natural state. For the purposes of the planned renaturization, a geographic information system (GIS) was created, enabling digital map generation, database creation, and calculations.

Agricultural activity results in water pollution from nitrogen and phosphorus compounds. Increased concentrations of nitrogen compounds pose a threat to animal and human health. The purpose of this study was to determine the impact of agriculture in a catchment basin on the level of surface water pollution from biogenic compounds. Spatial analysis of the land cover was conducted using GIS and was based on data from the Corine Land Cover databases. The study results indicated that high concentrations of nitrogen and phosphorus compounds existed in the surface waters. In the surface water, high concentrations of biogenic compounds occurred in both primarily agricultural catchments and in urbanized drainage areas. Water may be regarded as eutrophicated or at high risk of eutrophication because the majority of the nitrate concentrations at the monitoring sites exceeded a limit of 10 mg·dm⁻³ NO₃²⁻. Inadequate farming practices and poor sanitary conditions on farmsteads result in the leaching of biogenic substances into the water. To protect water from biogenic pollutants, it is necessary to adopt a new approach to fertilizer use and to improve the sanitary conditions of agricultural properties, which can be achieved by, among other things, the installation of drainage systems in rural areas. Our recommendations include the protection of river valleys as follows: by stopping deforestation, by preserving natural riparian vegetation, and by reducing the volume of intensified agricultural activity or introducing so-called “precision farming.”

The rapid development of scanning technology, especially mobile scanning, gives the possibility to collect spatial data coming from maritime measurement platforms and autonomous manned or unmanned vehicles. Presented solution is derived from the mobile scanning. However we should keep in mind that the specificity of laser scanning at sea and processing collected data should be in the form acceptable in Geographical Information Systems, especially typical for the maritime needs. At the same time we should be aware that data coming from maritime mobile scanning constitutes a new approach to the describing of maritime environment and brings a new perspective that is completely different than air and terrestrial scanning. Therefore, the authors, would like to present results of an experiment aimed at testing the possibilities of using mobile scanning at sea. Experiment was conducted in the harbour and the associated environment of neighbouring southern coast of the Baltic Sea
