Fish passages represent a key engineering and ecological measure for restoring the longitudinal connectivity of watercourses disrupted by hydraulic structures. This paper presents the conceptual design of a nature-like fish passage at the Djerdap 2 hydropower plant on the Danube River. The study includes route definition, hydraulic sizing under com...

This paper presents an integrated hydraulic, energy and economic analysis of two diversion-system alternatives for the small hydropower plant “Merćez” on the Lukovska River. Two technical concepts are considered: Alternative I – water conveyance through a pressurized steel pipeline, and Alternative II – an open-channel diver...

Nature-like fish passes are complex hydraulic–ecological systems whose performance is often assessed through fragmented monitoring approaches. This paper proposes an integrated KPI-based framework for the evaluation and classification of fish pass functionality, combining biological, hydraulic, and operational indicators within a structured m...

Within an integrated planning approach, urban streams are a valuable natural resource with strategic significance for creating resilient cities. This paper explores the revitalization of small urban streams within sustainable development practices, and discusses the manifold benefits that it brings about. Best practice examples are presented to ill...
