Rainfall kinetic energy–intensity relationships for rainfall erosivity estimation were established on the basis of raindrop size distribution measurements (optical disdrometer, rain gauges) and rainfall intensity measurements during a one-year period performed on 2 locations in SW Slovenia. Two exponential KE–I relationships were established for each measuring site, and their performances were tested and compared with the performances of selected 11 KE–I relationships expressed with linear, linear-log or exponential formulations.

We performed a model analysis of the concentration of the algal species Peridinium gatunense (Dinoflagellate) in the Lake Kinneret, Israel, where sudden ecosystem changes occurred in the mid 1990s. We applied an automated modelling tool (Lagramge), and by an expert visual estimation we proposed one optimal model capable of long-term predictions of algae concentrations.

We performed an experimental study on sedimentation efficiency inside two types of circular settling tanks with continuous operation. The two tanks differ in inlet and outlet configurations. Research was focused on the influence of flow field on the sedimentation efficiency of both settling tanks. Sedimentation efficiency was assessed by measurements of inlet and effluent suspension concentrations. As a research method we also applied computer aided visualization.

A visualization method was employed for accurate non-intrusive measurement of velocity fields at a physical model of a sharp-crested rectangular sideweir under subcritical flow. The experimental observation of velocity vectors at various horizontal planes over the entire width of the main channel confirms that the flow conditions at sideweir are non-uniform. The coefficients of non-uniform velocity distribution were in the range from 1 to 1.1. The present study focuses on the relation between the longitudinal components of the overflow velocities and the corresponding cross-sectional average velocities in the main channel, detailed as a function of flow depth and of location along the sideweir crest. For different sideweir geometries, these coefficients varied between 1 and 1.2.

On 12 Slovenian rock aggregates (limestone, dolomite bedrock, naturally occurring river alluvium), we performed investigations on the nature of fines using 6 different methods. The relationship between properties of different fines were recognized and used as a basis for drafting Slovenian national criteria for SE and MB values which have been in an official trial use since 2007.
