Dissertation Research: Relating Riverine Aquatic Habitat to Three-Dimensional Flow and Geomorphological Form

本论文的研究将以创新的方式，河流地貌学和河流生态学的理论和方法相结合，以更好地理解人类影响的河流系统中的水动力复杂性和栖息地多样性之间的关系。 其目的是将鱼类栖息地在几个中西部河流的河流系统的各种三维属性。分析尺度大致对应于河道沙坝、水池和浅滩。 将对河道横截面、流体流动模式、鱼类种群和水质进行实地测量。 将进行统计和地理信息系统分析，以揭示生态和地貌之间的联系。 结果是特别密切相关的流生态和栖息地管理。

This dissertation research will link, in an innovative fashion, theory and methods in fluvial geomorphology and stream ecology to provide an improved understanding of the relations between hydrodynamic complexity and habitat diversity in human-impacted stream systems. The intent is to relate fish habitat in several Midwestern streams to various three-dimensional attributes of the fluvial system. The scale of analysis corresponds roughly to channel bars, pools, and riffles. Field measurements will be made of channel cross-sections, fluid flow patterns, fish populations, and water quality. Statistical and GIS analyses will be conducted to reveal associations between the ecology and geomorphology. Results are particularly germane to stream ecology and habitat management.
