Rainwater Harvesting System Scenario Analysis On Runoff Reduction Potential In Surabaya, Indonesia: A Geospatial Analysis For Brantas Hilir Watershed, Putri Sukmahartati

Department of Civil and Environmental Engineering: Dissertations, Theses, and Student Research

Global warming has become an environmental concern over the past several decades and its impact on the water cycle is very crucial to the well-being of the human population. In the hydrological cycle, water evaporates by the heat of the sun and atmosphere, where it is accumulated in the atmosphere via clouds and it then falls as rain. With warmer temperatures, more intensive evaporation and downpours occur. In addition, impervious surfaces are increasing as a result of urban development. Those surfaces cause more water to flow faster into open water bodies, creating more extensive flooding, and additionally reducing water quality. …
