Eutrophication Impacts due to urbanization: I m pact to aquatic habitat: Degradation of habitat structure, loss of pool-riffle structure, reduction in base flow, increased stream temperature, and decline in abundance and biodiversity. Fish kill at Lake Granbury.
Green Stormwater Infrastructure Rain garden- bioretention areas Porous pavements Green roofs Rainwater harvesting
What is a Rain Garden (Bioretention)? A rain garden is a beautiful landscape feature consisting of a planted shallow depression that collects rainwater runoff from roofs, parking lots and other impervious surfaces.
Bioretention in Road Median “We Bring Engineering to Life”
Volume Reduction Average Reduction: 49%
Load Reduction: Sediments Average Reduction 90%
Load Reduction: E. coli Average Reduction 64%
What is Porous Pavement? Porous pavement is a permeable pavement surface with a gravel reservoir underneath. it temporarily stores surface runoff before infiltrating it into the subsoil provides water quality treatment often appears as traditional asphalt or concrete but is without "fine" materials could also allow for grass growth
Types of Permeable Pavement Porous concrete Paver blocks Porous asphalt Turf Paver Expanded shale mix

Impact of Climate Change on Dallas Stormwater Network
Conclusions It is necessary to approach water the water cycle as whole in management strategies at city, watershed or country scale Such approach requires field data, modeling and research-based answers to be implemented Research-based strategies developed need to include stakeholder feedback to succeed Findings need to be integrated in academic curriculums and spread through extension programming
