First experience with measurement of phosphorus retention in the Lhotsk stream using TASCC method
Eutrophication of watercourses and reservoirs, specifically the enormous phosphorus load on water, has been the biggest problem for water management in the Czech Republic for several decades. Budget models are effective support for rational solution; apart from resources, they must include the river network characterization, i.e. the retention of phosphorus in streams. A direct method for measuring phosphorus retention in watercourses under well-defined conditions, i.e. a method providing generalizable retention parameters, is fundamentally lacking and it could significantly increase the accuracy of the current models. It seems that TASCC method (Tracer Additions for Spiraling Curve Characterization) has such potential. In this article, we describe its first application in the Czech Republic, namely in the experimental basin of the Lhotsk stream (Beneov district).
Drainage and sewage treatment in Moldova – current state and perspectives
The article provides basic information on the current state of drainage and sewage treatment in Moldova. These data are a summary of survey findings from individual localities (usually cities over 10 000 inhabitants) carried out within the framework of the Czech Republic’s foreign development cooperation project.

The second year is running the Project Civil measurement science transparency water ponds in the Czech Republic. Second year on hundreds of lakes intensively measure water transparency, and in three key periods: in the second half of April and June, and in August and September.
