Scale-invariant topography and porosity variations in fluvial sedimentary basins
We consider a model of • floodplain evolving with channel •vulsion, deposition, •nd erosion. Avulsion is modeled as • r•ndom process in sp•ce and time. Sediment ransport is modeled by the diffusion equation (Culling's model). The power spectrum of v•ri•tions in the topographic profiles predicted by the model S(k) is proportional to k -2 (where k is the w•venumber). This is the Brown noise often...
متن کاملThe Response of Fluvial Systems to Large Flood Events
In the summer of 2001, an intense thunderstorm in southeastern Caspian Sea triggered a catastrophic flood in the Madarsoo basin . Use of methods including high-resolution aerial photographs and satellite images interpretation, multi-date mapping, hydraulic calculations and field observations made possible the documentation of the geomorphic impacts on the Madarsoo River and its tributaries. Geo...
متن کاملNumerical study of sedimentary impact of a storm on a sand beach simulated by hydrodynamic and sedimentary models
− In marine coastal environments, storms have a major morphological impact on sand beaches. This study, part of the French Programme National d’Environnement Côtier, consisted in developing and applying hydrodynamic and sedimentary models to simulate the major processes that modify sand beaches. In order to study sediment dynamics, we developed three models to simulate waves, currents and sedim...
متن کاملShaler: in situ analysis of a fluvial sedimentary deposit on Mars
This paper characterizes the detailed sedimentology of a fluvial sandbody on Mars for the first time and interprets its depositional processes and palaeoenvironmental setting. Despite numerous orbital observations of fluvial landforms on the surface of Mars, ground-based characterization of the sedimentology of such fluvial deposits has not previously been possible. Results from the NASA Mars S...
متن کاملFluvial sedimentary deposits on Mars: Ancient deltas in a crater lake in the Nili Fossae region
[1] New spacecraft observations in the Nili Fossae region of Mars reveal two valley networks (!80 and !200 km long) that each formed distributary fans as they entered an ancient 40-km diameter impact crater. An outlet channel on the eastern crater rim, lying at an elevation above the fans, suggests these fans formed as subaqueous deltas in a crater lake. Water flowing in the valley networks ent...
