CAREER: Ecohydraulics: Simulation of Physical Processes in River Ecosystem Management

9874754 goodwin该奖项旨在支持在规划、工程设计和实施改善程序时考虑到影响河流改善的所有因素的过程研究。实施河流整治计划需要了解影响进行整治决策的因素之间复杂的相互作用，并确定其经济成本和效益。这些因素基本上是由盆地的地貌决定的，这些地貌影响着盆地对引发洪水的条件的反应。流域响应，包括泥沙运移和河岸侵蚀，受到发展和土地利用模式变化的显著影响。研究者在爱达荷州确定了规模相对较小的研究地点，用于开展这项研究。其中包括弗兰克·丘奇荒野（Frank Church Wilderness）的一处未受干扰的原始遗址，红河（Red River）上的一处被砍伐并布满地雷的遗址，以及爱达荷州西南部奥怀希山脉（Owyhee Mountains）雷诺兹溪（Reynolds Creek）排水的牧场盆地。研究中选择的高度城市化的流域包括加利福尼亚州里士满的Wildcat Creek和加利福尼亚州太平洋的圣佩德罗溪。水力研究的目标预计将集中在俄勒冈州奥尔巴尼和塞勒姆之间的威拉米特河，作为一个大型河流的例子，加利福尼亚州的纳帕河作为一个中等规模的河流。该奖项的提案是对教师早期职业发展（Career）计划的回应，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。这个项目的研究部分预期将产生比现在更好的程序，以便将河流恢复的费用与现在可能获得的利益联系起来。教育部分包括一种方法，使城市和农村儿童对河流恢复感兴趣，通过在本科课程中使用实地获取的数据，向本科生介绍生态恢复，并为红河遗址建立一个项目网页和视频，其中将包括计算机模拟洪水和洪水引起的地貌变化。

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.
