On Monday, Crozier & Associates Partner and Senior Water Resources Engineer Nick Mocan presented alongside Dr. Kevin Stevens of Wilfrid Laurier University at the 2019 CWRA National Conference on how targeted vegetation plantings can be used to enhance water quality treatment in stormwater management facilities.
Their presentation covered the last 8 months of site visits, vegetation surveys, and water sampling at a stormwater management (SWM) pond near a subdivision in the Credit Valley Conservation Authority watershed. Dr. Stevens, an expert in wetland plant ecology, discussed the science behind how plants can contribute to water quality treatment, the types of vegetation found at the site, and preliminary water quality analysis results. Mocan drew on his expertise in stormwater management to review the impact of climate change on SWM facility inputs, hydrology, and hydraulics. Mocan also highlighted how this multi-disciplinary research can help stormwater facilities cope with the effects of a changing climate.
Preliminary results show that vegetation in the subject SWM pond is performing nutrient removal year-round, but that removal rates are diminished during colder periods. However, there appear to be increasing removal efficiencies as vegetation begins to re-establish itself. Vegetation surveys also noted that volunteer species are contributing to increased species richness, but these plants may not all be desirable.
The second stage of this project will involve developing targeted planting mixes based on local hydrologic, hydraulic, and environmental conditions. We anticipate these mixes will provide improved water quality treatment in SWM facilities, prevent incursions of invasive plant species, and contribute to the reduction of nutrient loading in urban stormwater that reaches lakes and streams.

One of the six lectures composing 'Exploring Ocean, Explore the Planet Earth' online course offered by Blue Green Foundation Bangladesh & Octophin. The training was attended by participants from 40 countries. The presentation is organized in three sections: (i) the good- describing what benefits we get from the Ocean, (ii) the bad- bad things happening to the ocean because of human activities, e.g. climate change and their impacts on the sea, (iii) the ugly- very bad things that are happening to the sea due to anthropogenic activities, pollution and their impacts on ocean life forms are discussed in this section.
Marine pollution is the introduction by man, directly or indirectly, of substances or energy into the marine environment (including estuaries), resulting in such deleterious effects as: harm to living resources; hazards to human health; hindrance to marine activities including fishing; impairing the quality for use of sea water and reduction of amenities
Seaweeds are taxonomically diverse group of marine plants from which the land plants diverged over fifty crore years ago, which are found in the coastal region between high tide to low tide and in the sub-tidal region up to a depth where 0.01 % photosynthetic light is available. Plant pigments, light, exposure, depth, temperature, tides and the shore characteristic combine to create a different environment that determines the distribution and variety among seaweeds. It contains photosynthetic pigments and with the help of sunlight and nutrient present in the seawater, they photosynthesize and produce food which have several health benefits and uses. The important to know about the ecology and distribution of seaweed and to distinguish the different algal groups based on their characteristics. In recent, the utilization of seaweed increased due to various available properties. The different usages are food, beauty enhancer, organic manure, fertilizer, feed complement, medicines, water treatments. This review is an attempt to highlights the seaweed with all the relevant application and uses.
This PowerPoint was made for a biology class to help inform students on the Georgia Southern campus about the problems and solutions facing sea turtles and the coral reefs.
..I.D.E.A.S. Ecosystem Facilitation offers a sustainable solution to maintaining retention ponds. This systems involves strategic plantings of native aquatic flora that will provide a filtration buffer for high nutrient run-off, further decreasing unwanted algal blooms and creating an area of high biodiversity.
