Abstract. It has been well established that during the late Quaternary, Khvalynian transgression of Caspian Sea occurred, when sea level rose tens meters above present level. Here, we evaluate physical feasibility hypothesis maximum phase this extraordinary event (known as “Early transgression”) could be initiated and maintained for several thousand years solely by hydroclimatic factors. The is based on recent studies dating highest stage (well +10 m a.s.l.) to final period deglaciation,...
Abstract Empirical prediction equations of the form W = aQ b have been reported for rills and rivers, but not ephemeral gullies. In this study six experimental data sets are used to establish a relationship between channel width ( , m) flow discharge Q m 3 s −1 ) gullies formed on cropland. The resulting regression equation 2·51 0·412 ; R 2 0·72; n 67) predicts observed reasonably well. Owing logistic limitations related respective set ups, only relatively small runoff discharges (i.e. <...
Abstract The processes of sheet, rill and gully erosion on the slopes Russian Plain are controlled by same factors as elsewhere: cover, erodibility, erosivity landform. combination land‐use history variations in these bio‐physical produced a that is unique to this area. most eroded soils occur Non‐Black Earth area, especially where there soddy‐podzolic soils. Over entire Plain, 99 × 10 9 m 3 soil have been lost from since AD 1696. On arable land, layer <10 cm thick has 82% 10–20 removed...
Abstract The process of gully erosion at the active stage is far from equilibrium; rather, shows characteristics a self‐organizing system that close to crisis. This qualitative description similar understanding open dynamic systems state selforganized criticality (SOC). We tried find quantitative attributes SOC in numerical simulations evolution with model. Three scenarios were used: (1) controlled by initial topography and texture, when discharge base level are constant; (2) constant lowers...
The Yamal Peninsula occupies the northern part of West Siberian Plain in Russia. This territory has rapidly developed due to exploitation several gas fields. At same time, is one most severely gullied landscapes Arctic. potential risk damage environment or structures and cost such damages are very high there. erosion cumulative by runoff above critical, calculated for each point at a catchment. Calculations take into account geomorphic, lithological, vegetation cover thresholds, realized...
Abstract Floodplain morphology is described in relation to channel pattern changes the past. The oldest segments of present-day floodplains were formed Late Valdai (Weichselian). Their inherited from large palaeomeanders (macromeanders) under extremely high discharge conditions. A map spatial distribution macromeander relics on East European Plain given. Various floodplain have a spectrum ages that may reflect only selected portions river history. most widespread morphological units...
Abstract The Stavropol region of southern Russia is severely affected by human‐induced gully erosion. A lack detailed information on the different stages formation resulting from major agricultural expansion c . 100 years ago, an obstacle for management and containment these systems. In this study we combine measurements particle‐bound radionuclides ( 137 Cs, 210 Pb ex , 226 Ra, 232 Th 40 K) classical geomorphology to investigate reconstruct phases development a during last years. We believe...
Fractal dimensions of the more than 200 large river networks former USSR were calculated. We use term «fractal» as «a structure consisted parts which are in some sense alike to whole». River don't possess complete self-likeness – fractal dimension changes with change measurer unit and chosen length rivers. Therefore calculations fulfilled lying within limits 1–10 km. from 1.1 1.7, corresponds aggregate short rivers (1–10 km) consisting 20–80% total network length. Then all studied have...
Abstract Field experiments at Tiramoana station 30 km north of Christchurch, New Zealand using an erosion plot 16·5 m long, 0·6 wide, and with a slope 14–14·5° on rendzina soil aimed to measure the variability flow velocity aggregates transport rate in shallow overland flow. Discharge/cross‐section area ratio was used estimate mean velocity, high‐speed digital video camera image analysis provided information about sediment variability. Six runs 0·5–3·0 L s −1 discharges were supercritical...
