Field Investigation of Flow Resistance Due to Vegetation Patch (Case Study: Shapur, Fahlian and Dalaki Rivers) [PDF]
Flow resistance in rivers with vegetation patches is one of the challenging parameters in river engineering. This study aimed to investigate the effect of vegetation patches on flow resistance in Shapur, Fahlian, and Dalaki rivers.

Snarks with Resistance $n$ and Flow Resistance $2n$
We examine the relationship between two measures of uncolourability of cubic graphs – their resistance and flow resistance. The resistance of a cubic graph $G$, denoted by $r(G)$, is the minimum number of edges whose removal results in a 3-edge-colourable graph.

Cell membranes resist flow [PDF]
SUMMARY The fluid-mosaic model posits a liquid-like plasma membrane, which can flow in response to tension gradients. It is widely assumed that membrane flow transmits local changes in membrane tension across the cell in milliseconds. This conjectured signaling mechanism has been invoked to explain how cells coordinate changes in shape,

Flow resistance law in channels with fully submerged and rigid vegetation
The estimate of flow resistance in vegetated channels is a challenging topic for programming riparian vegetation management, controlling channel conveyance and flooding propensity, for designing soil bioengineering practices.
