Development of Electronic Scour Depth Monitor

9727111 Burges这笔拨款为开发一种电子设备的费用提供部分支持，该设备用于监测砾石河床冲刷深度的时间进展。最终将建造10个设备，利用磁性开关系统记录一系列指示练习高尔夫球的通道，并进行现场测试。冲刷数据将被记录在存储芯片上，并在现场下载以供将来分析。这些仪器的设计使用寿命至少为6个月。目前还没有类似的设备来记录风暴期间砾石河床冲刷的时间进程，这种设计既聪明又简单，很有可能发挥作用。一个成功的冲刷深度监测仪将在土木工程、沉积学和渔业科学等领域具有实际应用价值。冲刷数据对于桥梁工程设计和预测美国西部砾石河床鲑鱼幼虫的招募尤为重要

9727111 Burges This grant provides partial support for the costs of developing an electronic device for monitoring the temporal progression of scour depth in gravel stream beds. Ten devices utilizing a magnetic switch system to record the passage of a sequence of indicator practice golf balls will eventually be built and field tested. Scour data will be recorded on a memory chip and downloaded in the field for future analysis. The instruments will be designed to have a useful life of a least six months. No comparable device currently exists with which to record the temporal progression of scour in gravel stream beds during storm events and this design is both clever and simple enough to have a high probability of being functional. A successful scour depth monitor will have practical application to problems in civil engineering, sedimentology and fisheries science. Scour data are particularly important for the engineering design of bridges and to prediction of salmonid larval recruitment in gravel stream beds of the western U.S. ***
