The study fo cuses on Up per Cre ta ceous-Paleocene de pos its from the Beskid Śląski moun tain range in south ern Po land con sti tut ing the Istebna Beds. The Istebna Beds, also re ferred to as the Istebna For ma tion, are part of the Silesian tec tonic unit, which forms the Outer Carpathian fold-and-thrust belt (part of the Al pine-Carpathian sys tem). The re sults of qual i ta tive and quan ti ta tive lithological-sedimentological stud ies were the ba sis for the in ter pre ta tion of lithofacies types, sed i men tary pro cesses and palaeoenvironment as well as for the re con struc tion of the ar chi tec ture of the depositional sys tem. The anal ysis con ducted on the ba sis of field de scrip tion of the de pos its shows the prev a lence (nearly 70%) of siliciclastic strata rep resent ing a sand stone-con glom er ate as so ci a tion (S-C), which is the main sub ject of this work. The S-C lithofacies: sand stones, grav elly sand stones, sandy con glom er ates and con glom er ates con sti tute the de pos its formed mostly by mass grav ity-flows such as sandy-to-grav elly de bris flows.

This study simulates turbidity currents through a number of idealized channels using a steady, one‐dimensional, depth‐averaged model to determine if modeled flows starting from a wide range of initial conditions might reach an equilibrium state where clear‐water entrainment balances fluid mass lost to flow stripping or overspill processes. To accomplish this, we calculated flow dynamics based on 1,000 sets of randomized initial conditions, identified flows that successfully traversed the system, and then extracted the flow height, velocity, and sediment flux at the channel terminus. We then systematically changed channel and flow properties using a wide range of values and calculated the length required for the simulated currents to reach the new equilibrium conditions. We found that modeled turbidity currents may evolve to a single equilibrium state consistent with the physical channel and flow properties regardless of the initial flow conditions. Additionally, we found that simulated turbidity currents generally required 1–40 km of downflow distance to adjust to new equilibrium conditions resulting from changes in the channel slope, channel height, channel width, coefficient of bed friction, and meander radius of curvature. Changes in sediment grain size and suspension cloud concentration resulted in adjustment lengths exceeding 100 km. Shorter adjustment lengths resulting from flow stripping suggest that this process might play an important role in flow filtering. The fact that modeled flows adjust to new equilibria over tens of kilometers suggests that they are less sensitive to upstream flow conditions in longer channels.
