9874754GoodwinThis is an award to support research on a process by which all factors that impact on riverine enhancement can be taken into consideration during planning, engineering design and implementation of enhancement procedures. Implementation of river enhancement plans requires an understanding of the complex interactions between and among factors that influence the decision to undertake enhancement and determine their economic cost and benefits. These factors are basically determined by the basin's geomorphology which influences its response to conditions that cause flooding. Basin responses including sediment transport and bank erosion are significantly influenced by changing patterns of development and land use. The investigator has identified study sites in Idaho that are relatively small in scale to use in conduct of this research. These include a pristine, undisturbed site in the Frank Church Wilderness, a logged and heavily mined site on the Red River and a grazed rangeland basin drained by Reynolds Creek in the Owyhee Mountains of southwestern Idaho. Selected heavily urbanized drainage basins selected for study include Wildcat Creek in Richmond, California and San Pedro Creek in Pacifica, California. The hydraulic research objective is expected to focus on the Willamette River between Albany and Salem in Oregon as an example of a large-scale river and the Napa River in California as an intermediate-scale river. The proposal leading to this award was submitted in response to the Faculty Early Career Development (CAREER) Program that emphasizes combining discovery of new knowledge with inspired teaching and enthusiastic learning. The research component of this project is expected to result in better procedures than are now available for relating of the costs of riverine restoration to benefits gained than is now possible. The educational component includes an approach to interest inner-city and rural children in river restoration, introduce undergraduates to ecological restoration by using field-acquired data in undergraduate courses and establishing a project web page and video for the Red River site that will include computer simulations of floods and the geomorphological changes resulting from flooding.

9874754Goodwin 该奖项旨在支持在规划、工程设计和增强程序实施过程中考虑影响河流增强的所有因素的过程研究。 河流治理计划的实施需要了解影响河流治理决策并确定其经济成本和效益的因素之间复杂的相互作用。 这些因素基本上是由流域的地貌决定的，流域的地貌会影响其对引发洪水的条件的响应。 包括沉积物输送和河岸侵蚀在内的流域响应受到开发和土地利用模式变化的显着影响。 研究人员在爱达荷州确定了用于开展这项研究的规模相对较小的研究地点。 其中包括弗兰克教堂荒野 (Frank Church Wilderness) 中的一处原始、未受干扰的地点、红河 (Red River) 上一处被砍伐和大量采矿的地点，以及爱达荷州西南部奥怀希山脉 (Owyhee Mountains) 雷诺兹溪 (Reynolds Creek) 排水的放牧牧场盆地。 选择进行研究的高度城市化流域包括加利福尼亚州里士满的野猫溪和加利福尼亚州帕西菲卡的圣佩德罗溪。 水力研究目标预计将集中于俄勒冈州奥尔巴尼和塞勒姆之间的威拉米特河（作为大型河流的例子）和加利福尼亚州纳帕河（作为中型河流的例子）。 获得该奖项的提案是为了响应教师早期职业发展（CAREER）计划而提交的，该计划强调将新知识的发现与启发式教学和热情学习相结合。 该项目的研究部分预计将产生比现在更好的程序，用于将河流恢复成本与所获得的效益联系起来。 教育部分包括激发内城和农村儿童对河流恢复的兴趣，通过在本科课程中使用现场获得的数据向本科生介绍生态恢复，以及为红河遗址建立一个项目网页和视频，其中包括洪水和洪水造成的地貌变化的计算机模拟。
