Fish Passage & Habitat: Turbulent Jets and Environmental Hydraulics

这个水资源工程的研究项目提供了许多机会来研究新兴的生态水力学领域的问题。本方案包括三个主要项目：1)河流鱼类通道及生境结构；2)湍流射流在水利工程中的应用；3)环境水力学。河流中的鱼类通道和栖息地结构：鱼类通过河流中人为或自然障碍物的通道对鱼类的生存至关重要。我的研究小组对各种鱼道的设计做出了重大贡献（例如水池和堰，丹尼尔，垂直槽和涵洞鱼道），因此这些可以设计用于大多数情况。我们已经对一种类似博尔德坡道的自然鱼道做出了初步的贡献，我们希望在未来五年内开发出一种一般设计，并研究河池型鱼道。湍流射流在水工结构设计中具有重要意义。我们研究了沉跃式消力池的水力学，并希望建立一个标准的水工建筑物下沉跃式消力池。我们已经开发了圆形液压跳跃的一般分析，并计划开发一个实际使用的一般设计。我们还在研究泥浆射流，以帮助阿尔伯塔省北部油砂池的回收，并为两相湍流射流做出一般性贡献。该项目具有颗粒状核废料修复的潜力。环境水力学：我们研究并帮助设计了埃德蒙顿市排水系统的柱塞式降轴。我们计划改善这些设计，以减少排水系统的气味问题。这些研究将与埃德蒙顿市合作进行，这可能会增加其在其他城市的实际应用。

This research program in water resources engineering provides a number of opportunities to investigate questions in the emerging field of eco-hydraulics. This proposal has three main projects: 1) Fish Passage and Habitat Structures in Rivers; 2) Turbulent Jets in Hydraulic Engineering; and 3) Environmental Hydraulics. 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. My research group has made significant contributions to the design of various fishways (e.g. pool and weir, Denil, vertical slot and culvert fishways) so that these can be designed for most situations. We have made a preliminary contribution to one type of nature-like Boulder ramp fishway, and we want to develop a general design of and also study the Riffle-Pool type during the next five years. Turbulent jets are very important in the design of hydraulic structures. We studied the hydraulics of submerged jump stilling basins and want to develop a standard basin for submerged flows below hydraulic structures. We have developed a general analysis of circular hydraulic jumps and plan to develop a general design for practical use. We are also studying slurry jets to help in the reclamation of oil sands ponds in Northern Alberta and to make a general contribution to two-phase turbulent jets. This project has the potential for the remediation of granular nuclear wastes. Environmental hydraulics: We have studied and helped design plungeflow dropshafts in the City of Edmonton's drainage system. We plan to improve these designs to reduce odour problems in the drainage systems. These studies will be done in collaboration with the City of Edmonton, which may increase its practical application in other municipalities.
