Fish passage and Habitat structures in Rivers: Fish passage past either man-made or natural obstructions in rivers is important for the survival of fish in our rivers. We have made significant contributions to the design of Pool & Weir, Denil and Vertical slot fishways so that these can be designed for most situations. We plan to develop similar designs for the so-called nature-like fishways. We also plan to study and develop suitable habitat for fish in rivers. Turbulent Jets are very important in the design of hydraulic structures, mixing in nature and industries. We plan to study and develop submerged jump stilling basins for use with hydraulic structures and basins for use in dryponds, which are important for municipal drainage systems. We are also studying slurry jets with the idea of helping in the reclamation of Oilsands ponds in Northern Alberta. Environmental Hydraulics: We have studied and helped design dropshafts in the Edmonton Municipal Drainage system. We plan to help in improving these designs to reduce odour problems in the Drainage systems. These studies have the collaboration of the City of Edmonton, which makes our research practical.

河流中的鱼类通道和栖息地结构：鱼类通过河流中的人为或天然障碍物对鱼类在河流中的生存非常重要。我们为水池和堰、Denil和垂直槽式鱼道的设计做出了重大贡献，因此这些鱼道可以设计用于大多数情况。我们计划为所谓的自然鱼道开发类似的设计。我们亦计划研究及发展适合鱼类在河溪的生境。紊动射流在水工建筑物设计、自然界和工业中的掺混等方面具有重要意义。我们计划研究和开发用于水工建筑物的潜跃式消力池和用于干水池的水池，这对市政排水系统很重要。我们还在研究泥浆喷射器，以帮助北方阿尔伯塔的油砂池塘复垦。环境水力学：我们研究并帮助设计了埃德蒙顿市政排水系统中的竖井。我们计划协助改善这些设计，以减少排水系统的气味问题。这些研究得到了埃德蒙顿市的合作，这使得我们的研究具有实用性。
