During the activities on the project “Development of the methodology for assessing the hydromorphological state in the lakes and the implementation of hydromorphological monitoring” (Hrvatske vode) in 2018, experts from the company Elektroprojekt d.d. and the Department of Geography (Faculty of Science, UNIZG) began mapping and field work in the area of Vransko Lake (Dalmatia, Croatia). The purpose is to gather and analyze spatial data and environmental indicators for the spatial analysis of the Vransko Lake Nature Park and the surrounding area. Based on the properties and their relationships, relevant geoindicators, bioindicators and combined indicators of spatial processes, landscape patches, spatial structure and condition of environment will be determined. During the initial stage of data collection and analysis, the emphasis is on geomorphological processes and forms (natural and anthropogenic), landscape elements and anthropogenic elements of the area. The goal is to connect the landscape structure and the general condition of the environment.

to a better understanding of physical and chemical
processes in complex karst geoecosystems. Special
challenges for researchers are ice caves. The ice contains
various fossil, geomorphological and chemical records of
the past that can be used for research of former processes
or creating climate profiles for paleoenvironmental
research. Also, the “pressing need” is to study ice caves
due to the significant ice loss that has been documented
for the ice caves worldwide.
This preliminary report is a part of the long-term project
dedicated to the research of deep caves on Velebit Mt.
and pointed to the influence of the large karst depression
microclimate to cave microclimate, e.g. ice and snow
accumulation. The one year study using T/RH data
loggers was conducted in Lomska duliba valley (Velebit
Mt.) known for frequent temperature inversion and low
air temperature, and in partially ice-snow filled Ledena
jama (Ice shaft) located at valley’s bottom. The main
research was focused on the entrance part of Ledena
jama, where the dynamics (accumulation and melting)
of perennial ice and snow is significant.

In the Krka river vally the corrosion intensity was measured using the method of standard limestone tablets. Tablets were set on five locations near Knin (Krčić) and Skradin. On each location three tablets were useded. In order to perform the physico-chemical analysis the soil was sampled in which the tablets were placed. By measuring the mass, that is by calculating the intensity of increment, or corrosion large differences between the tablets have been observed. In the area of Krčić increment amounts up to 0.7797 μm / yr., while in Skradin area corrosion amounts up to 0.2436 μm / yr. The obtained differences in increment and corrosion values could be related to diverse climatic condtions and to different physico-chemical properties of the soil, especially its pH, CaCO3 and humus content.

The paper deals with the changes in beach surfaces during the last 40 years in the bays of Rašćine, Juto and Kutleša. The main natural factors of their formation have been presented, but the focus of attention has been the anthropogenic influences that have disturbed their natural evolution, and the way in which this coastal system has reacted to anthropogenic modifications. The construction of coastal structures, as well as the uncontrolled disposal of material left after construction in the vicinity of the coast and even in the sea, due to the quick expansion of nearby settlements and tourism development, has provoked a surplus of sediments in the sea, causing progradation and erosion of particular beach segments"
