Abstract

. This study reports the applicability of hydrological modeling, HEC-HMS, integrated with Geographic Information Systems (GIS) to examine the rainfall - runoff relationship with a case study of Upper Ciliwung watershed. Spatial rainfall data derived from radar data used in the process of simulating rainfall - runoff and the results are compared with simulation results using the observed rainfall data. Analysis of the rainfall-runoff simulation was conducted based on spatial approach by comparing the differences and similarities between sub catchments. The simulations carried out for the flood events in 2002, 2007 and 2013. The results of the simulation of rainfall - runoff using C-Dopller weather rainfall radar data shows the sub-watershed of Ciliwung (Tugu) produced discharge with the highest volume in January - February 2002 and 2007, and also 16 - 17 January 2013, i.e. 117 mm, 124 mm and 46 mm, respectively. Physical characteristics of the watershed such as slope, land use, and soil type, are the factors that determine the high discharge value. The results of validation using RMSE and Nash produces small deviation value of the observation data. It shows that the use of weather radar data is reliable in the rainfall-runoff simulation in the Upper Ciliwung watershed

Abstract

Aquaculture practices in developing countries, particularly Indonesia, are currently operating without effective control measures, leading to high tidal and other climate-related issues. Therefore, this study aimed to modify Coastal Vulnerability Index (CVI) assessment to evaluate the physical vulnerability of coastal areas in Indramayu Regency, West Java (62 sections) to tidal flooding (Rob). A total of 6 primary characteristics, including geomorphology, beach slope, water level rise sea, coastline alterations, tidal range, and high tide, as well as 2 additional parameters, namely land cover and mangrove breadth, were used for analysis. Based on the evaluation, CVI was divided into four groups, including (1) low, (2) moderate, (3) high, and (4) very high. The results showed that Indramayu District struggled to recover from tidal flooding, with 24.56%, 22.13%, 41.03%, and 12.28% being placed in the very high, high, moderate, and low categories. This underscored the role of local governments in improving coastal communities' capacity to respond to tidal flooding disasters. Furthermore, the results were expected to be used by local governments to enhance disaster mitigation systems, particularly for coastal areas in developing nations with comparable ecological conditions.
