A design approach for determining the optimal flow pattern in a landscape lake is proposed based on FLUENT simulation, multiple objective optimization, and parallel computing. This paper formulates the design into a multi-objective optimization problem, with lake circulation effects and operation cost as two objectives, and solves the optimization problem with non-dominated sorting genetic algorithm II. The lake flow pattern is modelled in FLUENT. The parallelization aims at multiple FLUENT instance runs, which is different from the FLUENT internal parallel solver. This approach: (1) proposes lake flow pattern metrics, i.e. weighted average water flow velocity, water volume percentage of low flow velocity, and variance of flow velocity, (2) defines user defined functions for boundary setting, objective and constraints calculation, and (3) parallels the execution of multiple FLUENT instances runs to significantly reduce the optimization wall-clock time. The proposed approach is demonstrated through a case study for Meijiang Lake in Tianjin, China.

Aeration and Mixing Bring Hussain Sagar Lake`s Ecosystem Back to Life
Overview Hussain Sagar Lake in India faced an inflow of untreated waste and pollution causing decreasing DO levels and foul odors in the nearby community. An even more critical threat was eutrophication, or an excessive number of nutrients in the body of water, choking out the natural aquatic life. Given the lake is stagnate, circulation and the distribution of efficient aeration was needed to alleviate these issues. Challenge Hussain Sagar Lake is located in a recreational area with many visitors. The lake...
Safety vs. Environment Protection: Study Discovers Increasing Salt Levels in Lakes
A recent study published by the US-American National Academy of Sciences revealed an increasing salt amount in form of chloride in rural and urban freshwater lakes around the American continent. The scientists believe, that mainly road salt distributed on icy roadways is to blame. Increasing salt levels threaten eco systems Road de-icing salt is blamed for rising salt levels in freshwater lakes. This was uncovered by a study of the National Academy of Sciences carried out for the last one and a half year. In...
Mapping Bedrock Surfaces Near Lake Travis, Texas - Case Study
In May 2014 and May 2015, AGI conducted a hydrogeology workshop focused on training students how to use a resistivity meter for groundwater exploration at Lake Travis near Austin, Texas. Why groundwater exploration? This workshop’s purpose was important: As water—especially groundwater—becomes more and more scarce (and thus, valuable) knowing exactly where and how to find it will become more crucial. By training students how to use our resistivity meter for groundwater exploration, we’re...
Great Lakes restoration is under threat. Here’s why that matters
Degraded by decades of pollution, the North American Great Lakes are finding new life through cleanup efforts now threatened by proposed federal budget cuts. The St. Louis River, which flows into Lake Superior — the greatest of North America’s Great Lakes — has a long and turbulent history. Once a portal for Native American trade and a garden for wild rice, these waters that drain Minnesota’s north woods were polluted in the 19th and 20th centuries with waste from lumber, paper and...
