The project proposed is a research-oriented and a purely academic one. The work is on water habitats- for calmer waters, ex: lakes, bay areas, creeks, etc.
Considering the site context to be a lake, and if a floating habitable structure is proposed on its water surface, how much percentage of its overall exposed water surface area can be built without affecting the water and marine life quality.
Kindly also let me know which of the water quality parameters that will be affected like BoD, etc., and also other environmental consequences, if any.
Well,
Greetings Dr. Prasad
A question open for many possibilities, here 100% complete coverage, means turning the lake into a large water reservoir accompanied by the destruction of the ecosystem and transferring its water from the surface water system to a system similar to the groundwater system or similar to deep water in lakes such as Lake Baikal.
This method is useful in maintaining the amount of water in the lake and reducing the evaporation effect in areas suffering from high evaporation losses.
From the above mentioned abstract and for the purpose of maintaining the ecosystem in the lake , The cover area should not exceed 50% at a best cases, and provided that the cover seem to be like chess patch (to regulate the relationship between water and the atmosphere in terms of solar radiation and gas exchange), while ensuring that the inflow water content into the lake is almost equal to the outflow water , to ensure that the water does not stagnate. This is a general academic opinion. Thank you with all due respect.
Thank you very much Dr. Bayan for your answer. I fully agree with your explanation. Is there any regional or global standards in terms of safe % of lake area coverage without disturbing or harming the water quality ?? Can you provide some case studies related to the question. Thank you once again.

For example, Shadow balls are black balls made of plastic (Polyethylene) diameter 4 inches, used in water stores, ponds, small lake to prevent evaporation and contamination of water with dust and chemical reactions from the sun.
