| This paper presents hydrologic data collected over an eight-month period from four different green roof test treatments. These data are to quantify changes in soil water moisture content in response to rainfall on a commercially-available medium and soil mixtures designed by researchers at TCU to assess the most effective medium in terms of water retention and recharge, and improve irrigation management by accurately determining when the green roof media should be watered to maintain optimum plant growth without using excessive water. Results showed that soils treated with a surface tile and gravel mulch perform best hydrologically, with highest storm water retention and moisture contents than a native soil with no surface cover or a commercially-available soil medium. |
