Abstract
Karawang Regency in Regional Regulation (Perda) No.2 of 2013 concerning Regional Spatial Planning (RTRW) 2011-2031 in Article 54 mandates the development of industrial strategic areas in Telukjambe (Kec. Telukjambe Barat, Timur and Ciampel). Karawang in January 2014 experienced flooding at several points resulting from the overflow of the Cibeet River and the Citarum River. Distribution of this flood occurred in the district Telukjambe West, East, Ciampel, Karawang West and East. Underground river systems and cave networks in the Jatiluhur Formation have the potential to reduce the discharge load from existing surface rivers. Cave systems and underground rivers in the Kuta Tandingan Hills can reduce surface runoff by up to 80%. The porosity of the Kuta Tandingan Hills can reduce surface flow by 21%. The peak load of the Citalahab River occurs at the beginning of the river where the channel is narrow, but the additional load from the surface flow is so large.
