Abstract Riverbed clogging is key to assessing vertical connectivity in the hyporheic zone and often quantified using single‐parameter or qualitative approaches. However, driven by multiple, interacting physical bio‐geochemical parameters, which do not allow for a conclusive assessment of with In addition, existing assessments lack transparency repeatability. This study introduces Multi‐Parameter Approach quantify Clogging (MultiPAC), builds on standardized measurements (grain size...
The description of complex river environments requires interdisciplinary approaches to collect and manage manifold data types sources. Deriving comprehensive knowledge from sources is challenging necessitates not only environmental science but also statistics Software engineering. This study introduces a relational database framed in an application called River Analyst for creating managing with open-source standards (Python3 Django). We conceptualize models environments, which describe...
<p>Riverbed clogging, also referred to as colmation, describes the infiltration of fine sediment in gravel bed rivers. The infiltrated leads a reduction pore space and, worst case, sealing riverbed.

Many water bodies are, as a result of anthropogenic influences, such river straightening, bank fixation, or damming in accordance with the EU Water Framework Directive (2000/60/EC) not good ecological state anymore. With aim to return status for surface waters, restoration measures are implemented many rivers. However, success and sustainability often site-dependent require hence an objective assessment.In this study, Multi-Parameter Approach assess Clogging (MultiPAC) was used suitability...

<div> <table><tbody><tr><td> <p>The infiltration and accumulation of fine sediments in gravel riverbeds (clogging, colmation) is a natural process, especially rivers with heterogeneous particle size distributions. However, are characterized by regularly occurring flood events that lead to bed alterations hence, flushing infiltrated sediments. In the case high non-natural sediment inputs and/or regulated low...
<p>Clogging of riverbeds, also referred to colmation, has been frequently reported in residual flow river reaches. In such reaches, colmation occurs mostly due regulated (minimum) conditions without significant flood events that drive morphodynamics. Consequently, incoming fine sediments continuously deposit, infiltrate, and accumulate the gravel matrix riverbed. The negative effect clogged layers on ecology is well-known, especially with respect hyporheic interstitial leading...
