INVESTIGATING URBAN OPEN-GREEN SPACES IN KONYA THROUGH ECOLOGICAL QUALITY CRITERION

Urban open-green spaces, which are sustainably. designed, installed and managed, conserve water, lower the rate and volume of runoff water from rain, snowmelt and irrigation, and help reduce the amount of pollutants reaching surface water. In contemporary metropolitan cities, as a result of decreasing open-green areas and permeable surfaces, increasing impermeable surfaces rainwater has become wastewater. For this reason in Konya Closed Basin, groundwater can not be fed enough and rainwater fed groundwater has decreased. This research specifically deals with the permeable surface which is one of the ecological quality criteria. According to ecological quality criteria, the proportion of impermeable surface > 20% is considered as 'not suitable', 10-20% is 'acceptable' for intensively used open-green spaces, 5-10% is 'good' for general green spaces, and < 5% is 'ideal'. This study aims to investigate the permeable surface in some urban open-green spaces in Konya and identify the amount of rainwater which recharged underground.
