A fluorometer for measuring mixing and discharge in urban and aquatic environments

请拨资金购买便携式荧光计，用于测量城市和水生环境中荧光染料的浓度。荧光计提供染料浓度的精确测量。通过监测染料注入水体后的浓度，可以得到混合和稀释的速率。此外，通过测量注入染料充分混合后的相对浓度，可以准确测量城市系统废水的排放量。拟议中的荧光计将支持D. Zhu博士、N. Rajaratnam博士和P. Steffler博士关于湍流射流动力学、河流和湖泊中的污水混合、城市系统水力学以及水生系统水质建模和管理的研究项目。

Funds are requested to purchase a portable fluorometer for measuring the concentration of a fluorescent dye in urban and aquatic environments. A fluorometer provides accurate measurement of dye concentration. By monitoring the dye concentration after its injection in a water body, the rate of mixing and dilution can be obtained. In addition, by measuring the relative concentration of the injected dye after it is fully mixed, discharges of wastewater in urban systems can be accurately measured. The proposed fluorometer will support the research programs of Dr. D. Zhu, Dr. N. Rajaratnam and Dr. P. Steffler on the dynamics of turbulent jets, effluent mixing in rivers and lakes, hydraulics of urban systems, and modeling and management of water quality in aquatic systems.
