Abstract
Juana River is a river located in the north of Central Java. The downstream part of the Juana River flows into the North Java Sea. Problems with the Juana River include drought during the dry season and flooding during the rainy season. In addition, saline water intrusion makes it difficult for communities to access raw water. Flooding in the Juana River is caused by land use changes in the upper reaches of the river, the presence of a large number of fishing boats anchored downstream, flooding in the lower reaches, and the relatively gentle slope of the Juana River.
Currently, the Ministry of Public Works and Housing (Kementerian PUPR) is undertaking the construction of normalization, dam raising, and rubber dams in the Juana River.
This study aims to analyze river stability which is closely related to river management planning.
Analysis was carried out using HEC RAS to determine changes and morphological stability of rivers.
The results of the depth morphology stability calculation in the Juana River post-construction show that the riverbed is unstable.
