Abstract
One of the dangers that can arise in the karst area is the overflow of underground rivers. The Karst region is mostly composed of limestone which is soluble in water. Underground river flows may occur when impermeable layers are blocking the flow of water infiltration from surface through the weak zone such as fractures. One of the existing underground river systems in the Wonosari Karts area is the Bribin-Baron underground river which is one of the main river systems in the Karst Gunung Sewu region. The underground river system is similar to the U pipe system where as the water volume exceeds the capacity of the river, the flow of water can appear to the surface through one of its holes. In this study using literature and secondary data collection which then conducted field checking. Then we do the assessment and evaluation of data obtained and make recommendations on risk management in this area. From the analysis obtained there are several factors that can trigger underground river floods such as rainfall, morphology, geological structure. The results of the assessment and evaluation found that the good management of disaster risk overflow underground river in Karst Wonosari region is required in this area. Such as to estimate the areas that could potentially become an underground river burst. From this research is expected to contribute in disaster mitigation efforts in karst area.
