Fish Passage and Habitat Structures in Rivers: In the past several years, we have made many fundamental contributions to the hydraulics of Pool and Weir, Denil, Vertical slot and Culvert fishways. As a result, these fishways can now be designed for simple situations. We would like to extend this investigation, to measure the turbulence structures in all the four types of fishways, to enhance fish passage. Turbulent Jets & Related Investigations: In the past few years, we have made several contributions to the applications of turbulent jets in Hydraulic Engineering. It appears that it is important to measure the turbulent structure in the scour holes produced by these jets. For the jets with finite depth of submergence, it is necessary to measure the turbulent structure, to strengthen our understanding of this class of flows. We plan to make these measurements with our ADV. We are also extending our study of turbulent jets to turbulent slurry jets to help with the management of the Slurry Ponds at the Oilsands Facilities in Northern Alberta. Environmental Hydraulics: In the past ten years, we have started investigations into many aspects of municipal hydraulics. These studies have included the hydraulics of plunging flow dropshafts, which have been used in the City of Edmonton. Our studies have indicated that the energy loss in these dropshafts could be significant. We would like to extend our studies to include a wider range of height to diameter ratio of these shafts and understand the mechanism of this significant energy dissipation and make some measurements of the air demand in these dropshafts.

河流中的鱼类通道和栖息地结构：在过去的几年里，我们对池和堰、丹尼尔、垂直槽和涵洞鱼道的水力学做出了许多基础性的贡献。因此，这些鱼道现在可以设计为简单的情况。我们希望扩展这项研究，测量所有四种鱼道的湍流结构，以增强鱼类的通行能力。湍流射流及其相关研究：在过去的几年里，我们对湍流射流在水利工程中的应用做出了一些贡献。由此看来，测量这些射流产生的冲刷孔中的湍流结构是很重要的。对于有限深度的射流，有必要对其湍流结构进行测量，以加强我们对这类流动的认识。我们计划用adva进行这些测量。我们还将湍流射流的研究扩展到湍流泥浆射流，以帮助管理阿尔伯塔北部油砂设施的泥浆池。环境水力学：在过去的十年里，我们开始对市政水力学的许多方面进行研究。这些研究包括在埃德蒙顿市使用的下倾流降轴的水力学。我们的研究表明，这些降轴的能量损失可能是显著的。我们希望将我们的研究扩展到更大范围的这些轴的高度与直径比，并了解这种显著的能量耗散的机制，并对这些降轴的空气需求进行一些测量。
