The study area has been divided into two broad geomorphic units: the fluvial deltaic plain (FDP) and the fluvio-tidal deltaic plain (FTDP) based on the characteristic geomorphic features.
The lower Stony Gap incised valley is relatively broad and filled with quartzarenite fluvial facies consisting of downstream accreting elements with minimum thicknesses of 6 m; cross-sets within elements average 62.5 cm thick.
How and to what extent the longitudinal pattern of channel morphology is influenced by broad-scale variables is important to fluvial geomorphologists and stream ecologists.
It is argued that by improving physical modelling capabilities and coupling physical and numerical models, it should be possible to improve understanding of the complex interactions and processes induced by variable forcing within fluvial systems over a broader range of time scales.
The hierarchy of the fluvial system begins within a broad, relatively homogenous setting that imparts control on processes that affect stream function.
These hydrological changes have broad impacts on river flood and drought occurrences, water security, fluvial ecosystem, and delta safety.
Even when rates of impact are high, a subtle fluvial signature is retained on the landscape as broad, smooth intercrater plains that feature craters with variable amounts of infilling and rim erosion, including nearly buried "ghost" craters.
At our location, these changes expressed the combined influence of marine (e.g., tide, storm waves) and fluvial dynamics (e.g., floods), which are linked, on a broader scale, to sea-level variations and the regional climate regime.
In a historical context, fluvial geomorphologists are more apt to use physiographic regions to distinguish broad-scale variables, while stream ecologists are more apt to use the concept of an ecosystem to address the broad-scale variables that influence stream habitat.
