The objective of this study is to investigate the correlation between the advancement of flood research and the utilization of Geographic Information Systems (GIS) and multi-criteria evaluation techniques, both from a theoretical and practical standpoint. Additionally, this research seeks to identify potential ways to address the aforementioned relationship. The present study employs a thorough literature review methodology. In accordance with the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) methodology, a total of 28 papers were identified and included in the analysis, as they fulfilled the predetermined criteria. The findings of the study indicate that current research pertaining to the utilization of Geographic Information Systems (GIS) and multicriteria evaluation in flood control mostly centers around five key areas, namely natural factors, technical considerations, institutional factors, socio-economic factors, and financial factors. However, the aforementioned studies have identified specific areas of focus, including natural factors pertaining to climate, technical factors related to infrastructure, institutional factors concerning flood management strategies, socio-economic factors associated with demographics, and financial factors pertaining to financial obligations. However, there is a limited amount of existing research that specifically addresses flood management in developing nations. Therefore, it is anticipated that this study can serve as a valuable resource for future research endeavors, particularly in informing decision-making processes pertaining to the establishment of priorities in flood control plans. The primary subject of this study pertains to flood management occurrences within developing nations.
The main issue is that the watershed in Ciliman floods during the rainy season. Watershed Flood Ciliman carries sediment, sludge, rocks, and vegetation from either bank of the river that was uprooted as the flood came downstream. Many locations are prone to landslides, which encompass the entire river flow. Flood mitigation was carried out entirely hydraulically. The Cibinuangeun River Diversion and River Normalization Cilemer has been completed. One option is the notion of ecological hydraulics, which employs bioengineering approaches. The purpose of this study is to use the Analisys Hierarchy Process (AHP) to make decisions about which priority bio-engineering methods can be used to manage floods in the Ciliman Watershed in Banten Province. This study used a mixed-methods approach (quantitative with a less dominating qualitative component). The analysis hierarchy process (AHP) was used to choose priority bio-engineering methods for flood management in the Ciliman Watershed in Banten Province. This is shown from the weighting results for bush cushions reaching 0.467, while the weight for staked woody plant stem cuttings is only 0.332 and the weight for biopore infiltration holes is only 0.201.
The Ambang River Basin holds significant significance for the residents of Greater Malang in East Java as they confront the peril of flooding. In order to assist the government in attaining the Sustainable Development Goals (SDGs), it is necessary for the management of the Ambang River Watershed (DAS) to incorporate ecological, economic, social, institutional, and technological aspects. The objective of this study is to assess the sustainability of the Ambang Sub-watershed and determine the key elements that impact the management's sustainability of the Ambang Sub-watershed. This study employs methodologies such as observation, interviews, documentation studies, and literature evaluation. The Malang rapflood tool employs a descriptive analytic technique and Multidimensional Scaling (MDS) for analysis. The results indicates that the sustainability of watershed management in the ecological, social, institutional, economic, and technological dimensions is classified as sustained for the upstream and middle Ambang sub- watersheds. The sustainability status of the Ambang sub-watershed management is classified as unsustainable. Improving the sustainable management of the Ambang sub-watershed requires attention to 21 variables.
