Impact of floating urbanisation on water quality and ecology

  1. 1. The effect of floating urbanisation on ecology and water quality F.C. Boogaard(2)(4), R.E. de Graaf(1)(5), M. Dionisio Pires(3), V.

  2. 2. Content • Research questions • Effect on water quality • First inventarisation • Measurements – Innovating approach – First results • More info? • Knowledge exchange
  3. 3. Objectives / Research Question • The impacts of floating urbanization on water quality and ecology are largely unknown by water authorities and municipalities (needed for policy framework and regulations). • Research question: What are the (negative and positive) impacts of floating urban development on water quality and ecology?
  4. 4. 1/21/20154 Hypotheses *The shadow of floating houses reduces available sunlight. This lowers the dissolved oxygen levels in their vicinity. *Below the floating houses a hypoxic area is created and oxygen is transferred laterally by the adjacent water column. This lowers the dissolved oxygen levels in their vicinity. *Wind tunnel effect is produced by the floating houses increasing the turbulence of the water. This increases the mixing in the water column which reduces the dissolved oxygen vertical gradient. Research question
  5. 5. 1/21/20155 • Many quantities • Turbidity • Temperature • Dissolved Oxygen • pH • Electro conductivity • Nutrient Loads • Many interactions • Biological • Chemical • Physical Research Context: Water Quality
