The loess relief of the Nałęczów Plateau is characterised by the occurrence of a set of dis‐
tinctive forms, among which gullies stand out the most. These forms are relatively young,
and their formation and development is mainly associated with human agricultural activity.
At present, intensive relief changes are observed within some parts of the gullies, where
a process of piping is taking place, leading to the formation of new forms and the development
of existing ones. They are usually located in places that are difficult to access, and the dense
vegetation makes field surveys even more difficult. An additional problem is their complex mor‐
phology, which makes them not well mapped by ALS scanning. Thus, their accurate inventory
requires the use of a different technology, adequate to the complexity of the forms.
Field research was conducted in spring 2025 in the catchment of the loess gully “Mareczki”
(0.82km2) located on the Nałęczów Plateau, west of Wąwolnica. The catchment is used agricul‐
turally as arable land, while its bottom and the gully there, which is the main focus of interest,
is covered with forest and shrubs. TLS scanning of representative piping forms was carried out,
allowing rapid and highly accurate data collection of their morphology. Once the point clouds
were cleaned, high‐accuracy data were obtained, accurately representing the whole forms and
all their details. The data were analysed to determine the type and intensity of the morpho‐
genetic processes taking place, volume calculations, and morphometric features. Repeated
measurements are planned in order to delineate active zones, monitor the changes taking
place, determine the intensity of morphogenetic processes, and quantify them.
