About this tender
The procurement concerns oceanography and hydrology services for monitoring morphological changes on critical sections of the Drava River, commissioned by the Ministry of Sea, Transport and Infrastructure (Croatia). The purpose is regular collection of data during various water events so that spatial and temporal morphodynamic processes on the relevant river section can be determined. The resulting reports (Elaborati) are intended to analyse the collected data to support control and supervision of the navigable waterway's condition, technical improvement, and traffic-technological modernisation of the waterway. The data must be in a form and quantity sufficient for high-quality analyses that will underpin conclusions on changes in the riverbed condition over the planning period. Existing monitoring must be taken into account and its findings incorporated into the monitoring system. Methods, frequency and similar parameters must reflect current scientific and technical knowledge. The ultimate aim is to assess the equilibrium state of the section, where riverbed instability was previously identified, which creates an ongoing need for maintenance. The detailed scope is defined in the Project Task (Projektni zadatak), which forms an annex to the procurement documentation, together with the bill of quantities and other requirements set out in the tender documentation. The contract duration is not stated in the notice text provided.
Key requirements
- ✓Regular field data collection during various water events on the Drava river section
- ✓Morphodynamic analysis of riverbed changes to support navigable waterway control and maintenance
- ✓Integration of existing measurement programmes and use of contemporary scientific methods
