Hollow Creek Journal

Editorial Scope

Hollow Creek Journal covers the ecology and monitoring of small to medium-sized freshwater streams in Germany, with particular focus on the scientific methods and regulatory frameworks used to assess their ecological status.

Content draws on publicly available scientific literature, official LAWA and Umweltbundesamt documentation, applicable DIN EN ISO standards, and EU Water Framework Directive guidance documents. No original research is published; all factual claims are referenced to accessible public sources.

The publication addresses the following subject areas:

• Benthic macroinvertebrate biology and bioindicator methodology
• Physicochemical water quality measurement and sampling protocols
• Riparian and floodplain habitat structure and assessment
• Hydromorphological survey methods (LAWA Gewässerstrukturkartierung)
• Application of the German saprobie index and OGewV classification system
• EU Water Framework Directive implementation in Germany

Accuracy and Updates

All articles carry a "last updated" date. Water quality standards, assessment methods, and regulatory thresholds are subject to change as scientific consensus and EU directives evolve; readers are encouraged to verify current requirements with official sources before applying any information to regulatory or management purposes.

Content is not a substitute for professional ecological assessment or regulatory advice. For official water status data, consult the relevant Landesumweltamt or the Umweltbundesamt's online data portals.
