The timespan recorded in deposits from fluvial activity is a key gap our understanding of ancient environments on Earth and Mars. Because riverine sediment transport occurs under time-variable water discharge, common models that represent with single bankfull discharge require an intermittency factor. For this reason, the ability to predict factor values based environmental factors would improv...

The hydrological regime of large meandering rivers the West Siberian Plain in Late Pleniglacial/Late Glacial was reconstructed from hydraulic geometry palaeochannels. main tools for reconstruction were power law relationship between channel bankfull width and mean maximum discharge, taken downstream direction, relationships peak flood discharge contributing basin area. Reconstructed values dail...

Rivers are among the most biodiverse and endangered ecosystems on earth. In Europe, concern over their conservation promoted development of legal instruments for habitat species conservation, Habitats Directive, water resource management, Water Framework Directive. This protection demanded estimate river ecosystem surface different purposes. Different approaches allow to be measured at a low co...

Research regarding self-maintenance of pool-riffle river morphology has focused on hydraulics within individual couplets. Here, we make a scientific leap from one site to 702 couplets across northern California understand the frequency foundational velocity-reversal hypothesis. A geometrical, mass and energy conservation-based velocity reversal criterion was used predict occurrence reversal. On...

The numerical 1-D HEC-RAS modelling tool was supported by the estimation of sieve curve changes procedure to measure scale predicted discharges along a stretch stream in southern Poland on Olkusz Upland. calibrated mountain streams during high-stage events, using radiotracer application bedload transport. Particular terrain hypsometry, created dissolution limestone, forced deep erosion river va...

Logarithmic and variable-power equations that use the bed D84 grain size as a roughness metric reproduce general trend of flow resistance in streams with coarse beds, but they are unreliable for predictions individual reaches. For site-specific application these equations, I propose an effective height can be calibrated by making single measurement. test this idea using published velocity-depth...
