0083884StanfordRivers are currently viewed as linear segments where materials spiral downstream in relation to catchment setting and water yield. This project is designed to shift science toward a non-linear, more dynamic view that emphasizes energy dispersion and materials retention as the primary organizing elements of river ecosystems. This research is conceptually based on the view that alluvial flood plains are regional centers of ecological organization, owing to dynamic, non-linear processes linking water and materials flux and retention to interactive landscape-forming processes. This interaction creates a complex, dynamic array of resource patches and interfaces, thereby producing a regional hot spot of biodiversity (including a very wide array of migratory species). Important modifiers of system dynamics include drought, wildfire, flow and geomorphic regulation (dams and revetments) and invasions of nonnative species. The interdisciplinary team will develop an expert system derived from available empirical data describing the structure and function of alluvial flood plains. The team will use an existing, novel simulator that routes water during specified flows through a large flood plain in western Montana. A primary task is to develop a tactical plan for refining the model to allow it to be driven by remotely sensed data.

0083884StanfordRivers目前被视为线性段，其中材料螺旋式下游与集水区设置和产水量有关。 该项目旨在将科学转向非线性，更具动态性的观点，强调能量分散和物质保留是河流生态系统的主要组织元素。 这项研究是概念上的基础上认为，冲积平原是区域中心的生态组织，由于动态的，非线性的过程，连接水和物质通量和保留互动的生态系统形成过程。 这种相互作用产生了一系列复杂、动态的资源斑块和界面，从而形成了一个区域性的生物多样性热点（包括一系列非常广泛的迁徙物种）。 系统动力学的重要修正因素包括干旱、野火、水流和地貌调节（水坝和护岸）以及外来物种的入侵。 跨学科小组将开发一个专家系统，该系统来自描述冲积洪泛平原结构和功能的现有经验数据。 该团队将使用现有的新型模拟器，在蒙大拿州西部的一个大型洪泛平原上指定水流的路线。 一项主要任务是制定一项改进模型的战术计划，使其能够由遥感数据驱动。
