Succession modeling of river floodplain landscapes
The spatial organization of ecological units that constitute river floodplains was modeled using a recent image synthesis method. The model combined a purely spatial process, the stochastic pyramid, with analytical descriptions of ecological successions observed on each landform of the fluvial landscape. Because the stochastic pyramid is a generator of non-homogeneous, anisotropic, multicolored...
متن کاملHydrologic Variability of the Cosumnes River Floodplain
Natural floodplain ecosystems are adapted to highly variable hydrologic regimes, which include periodic droughts, infrequent large floods, and relatively frequent periods of inundation. Effectively managing water resources and maintaining ecosystem services provided by floodplains—and associated aquatic, riparian, and wetland habitats—requires an understanding of seasonal and inter-annual hydro...
متن کاملRiver Floodplain Connectivity and Lateral Fish Passage: A Literature Review
Floodplains play a key role in the ecology of the Upper Mississippi River; however, humans have significantly affected the ecological function of floodplains by isolating them from the main stem of the river with levees. Impoundment and channel training within the main stem also influence floodplain function by altering the flow of water through the system. Because of the key role hydrology pla...
متن کاملThe impact of nitrogen contamination and river modification on a Mississippi River floodplain lake.
Anthropogenic nitrogen contamination has increased in ecosystems around the world (frequently termed the "nitrogen cascade"). Coke production for steel manufacturing is often overlooked as a source of nitrogen to natural ecosystems. We examined sediment cores from a Horseshoe Lake, a floodplain lake located just East of St. Louis Missouri (USA) to test whether a coking plant effluent could be t...
متن کاملA Geomorphic Monitoring and Adaptive Assessment Framework to Assess the Effect of Lowland Floodplain River Restoration on Channel–floodplain Sediment Continuity
The state of the science of lowland river floodplain restoration reflects the relatively new and experimental nature of large river floodplain rehabilitation efforts. Based on results of a case study of floodplain restoration at the lowland Cosumnes River, California, we present a geomorphic monitoring and adaptive assessment framework that addresses the need to inform and utilize scientific kn...
