The Impact Of Blue Green Cities Implementation On Reducing Urban Flood In Yogyakarta City

Abstract

Urban flooding is a frequent problem in many cities. Unfortunately, many mitigation efforts still rely on conventional, unsustainable methods. A more sustainable approach to reducing flood discharge in urban areas is the Blue Green Cities concept. This study demonstrates that implementing Blue Green Cities strategies—such as infiltration wells, porous drainage, and permeable pavements—can effectively reduce flood discharge in Tegalrejo District, Yogyakarta City.
