TLDR
In this paper, bank failure episodes are concentrated at the early stages of lowering of channel water level due to the sensitivity of banks to removal of passive resistance, and high ground-water level accentuates seepage erosion which reduces bank stability.About:

River width adjustment. I : Processes and mechanisms
TL;DR: In this paper, the authors present the findings of the Task Committee (TC) with regard to width adjustment modeling and establish the geomorphic context within which width adjustments occur, and it demonstrates that width adjustment may take place over a wide range of scales in time and space.

Seepage caused tension failures and erosion undercutting of hillslopes
TL;DR: In this article, a 25-cm tall, 50-cm wide, and 20-cm long soil block with a focused inflow reservoir was constructed to investigate seepage gradient forces and the three-dimensional nature of particle mobilization and undercutting.

Numerical Modeling of Bank Instability by Seepage Erosion Undercutting of Layered Streambanks
TL;DR: In this paper, a numerical finite element model, SEEP/W, was used to simulate seepage particle mobilization, undercutting, and mass wasting on layered streambanks.

Does the weight of riparian trees destabilize riverbanks
Bruce Abernethy,Ian Rutherfurd +1 more
TL;DR: In contrast to the generally accepted stabilizing effects of riparian vegetation, the surcharge of trees on riverbanks has been widely implicated as a source of bank instability as mentioned in this paper, but it is unlikely that the weight of silver wattles growing on an otherwise stable bank section will directly cause mass failure.
Journal ArticleDOI
Channel inception in cohesionless sediment by seepage erosion.
TL;DR: In this article, a series of systematic experiments on channelization by seepage erosion with various sediment layer depths and chamber slopes was presented. But the authors did not find channel bifurcation using plastic pellets as sediment.

Rock slope engineering
Evert Hoek,Jonathan D. Bray +1 more
TL;DR: In this article, the authors discuss the geotechnical problems of rock slope design for the mining or civil engineer who is not a specialist in rock or soil mechanics; many work examples are included to assist in relating the techniques described to his own slope problems.

Stability of composite river banks
Colin R. Thorne,N. Keith Tovey +1 more
TL;DR: The stability of a cantilever depends on the balance of forces, motive and resistive, associated with the most critical mechanism of failure as mentioned in this paper, i.e., shear, beam and tensile failure.

An analysis of the processes of river bank erosion
TL;DR: In this paper, a stepwise multiple regression analysis of the conditions controlling the amount and distribution of river bank erosion was carried out and two main methods of bank erosion were identified, corrasion and slumping, and these appeared to be associated with the influence of river flow levels and antecedent precipitation conditions, respectively.

Magnitude and distribution of rates of river bank erosion
TL;DR: In this article, bank erosion on rivers in Devon over a 2½ year period produced mean rates ranging from 0.08 to 1.18 meters per year and a maximum rate of 2.58 meters per month.
