<p><em>Flood in Surakarta mostly due to overflowing rivers that flow through the region of Surakarta. The river is part of the urban drainage system. Department of Public Works (DPU) as the local government agency is responsible for the drainage management in Surakarta. One of form of implementation of the river management as part of drainage system is river revitalization program of Pepe River downstream which performed by the DPU. Despite Pepe River downstream revitalization program has been implemented in a variety of activities, the event of flooding due to overflowing Pepe River downstream still occur. Where as the flood is one of the performance indicators of urban drainage system. Thus, from that background it can be defined in research formulation problems, that is how the influence of the river revitalization performed by the DPU Surakarta against Pepe River downstream performance as part of urban drainage system in Surakarta. </em></p><p><em>This research uses quantitative descriptive analysis supported by several analytical techniques including descriptive narrative analysis to identify the characteristics of the revitalization of Pepe River downstream and paired simple t-test analysis to identify the changes of drainage system performance. Next, the relations from the results of both analysis will be identified using explanatory descriptive analysis. Based on the analysis results, it shows that the characteristics of the revitalization of Pepe River downstream is categorized in moderate intensity, because it only includes physical and social activities. Although there are improved changes in the drainage system performance. On the river section I, there are less significant changes with the number of the biggest changes ison the indicator of gabions, that is 11. On the river section II, the drainage system performance changes are significant with the number of the biggest changes is on the indicator of sedimentation, that is 38. In river section III, there are less significant changes with the number of the biggest change is on the indicator of garbage accumulation, with a score of 21.Therefore, it can be argued that the river revitalization program performed by the DPU Surakarta affects the Pepe River downstream performance as the primary drainage channel in the drainage system in Surakarta. The influence can be seen from the reversion of river functions as a drainage channel which is marked by changes in Pepe River downstream drainage system performance from before the river revitalization performed and after the revitalization performed, which is improved.</em></p><p><em> </em></p><p><strong><em>Keywords</em></strong><em>: river revitalization, catchment area, drainage system performence</em></p><p> </p>

Abstract. Scientific literature reports a plethora of numerical tools of different complexity (e.g. 1D, 2D raster-based or full 2D models) for flood hazard and flood risk evaluation. The correct identification of the appropriate model still represents a key aspect in the overall flood hazard process even though the potential of these modelling instruments are increased by the availability of high computational resources and by the amount of high-resolution topographic data provided by recent survey techniques. Given this context the present analysis investigates the effects of minor drainage networks on the estimation of flood hazard in a flood-prone area along the Enza River, close to the village of Sorbolo a Levante (RE, northern Italy). By means of a full 2D hydraulic model (Telemac-2D), the effects of the drainage system is analysed using three unstructured meshes with different degrees of complexity: (1) the minor drainage system allows the possibility to convey water outside the study area (REF); (2) the drainage system is reproduced only in terms of preferential flow-paths (REF-noFlow); (3) the drainage network is completely neglected (REF-noDN). The analysis indicates that the maximum flood extent seems not to be influenced by the mesh schematization, while water depths and the total volume are significantly related to the model schematization. Even if this analysis refers to a specific case study and further investigations are needed, it shows the fundamental role of the drainage network in controlling water depth distribution and the duration of the inundation, which should be accurately reproduced by numerical models.

Tidal flood is a disaster that threatens coastal areas due to sea-level rise and land subsidence. One of the sub-districts in the city of Semarang, which is included in the tidal flood-prone area in every years, is the North Semarang Sub-District. The area of tidal flood is 55.95 Ha and the data of estimated generation of tidal flood waste in the North Semarang Sub-District is +/- 70 tons. Lack of planning for handling waste disasters, especially for tidal flood waste, is a challenge related to environmental and economic impacts that occur at tidal flood sites. This study aims to examine the quantification of the cost of handling tidal flood waste using quantitative descriptive analysis cost accounting calculation method. The calculation is done by considering several things, namely the activity of handling waste, the need for handling waste, as well as the calculation of the cost of handling tidal flood waste. The total cost of handling tidal flood waste in North Semarang Sub-District is IDR 14,209,324,000/year or IDR 1,184,110,333/month. The results of the calculation of the overall cost are then divided by the area of the tidal flood so that the unit cost of handling waste per m2 is IDR 2,117/m2.

Pollution Impacts

For upgrading the urban drainage system (UDS) the reduction of pollution impacts is the priority task concerning the environmental protection of the receiving waters. With simulation models the interactions between surface, sewer systems, overflow structures and treatment facilities within the UDS can be shown. Models to simulate the pollutant impacts, transport and the effects on the receiving waters are available. In a first step a pollutant transport model of sewer systems and a model to simulate the wastewater treatment processes are connected. With these models the efficiency of upgrading measures can be checked in all parts of urban drainage systems.

Non Linear Systems

Conventional UDS models are mechanistic which though appropriate for design purposes are less well suited to real-time control because they are slow running, difficult to calibrate, difficult to re-calibrate in real time and have trouble handling noisy data. At Salford University a novel hybrid of dynamic and empirical modelling has been developed, to combine the speed of the empirical model with the ability to simulate complex and non-linear systems of the mechanistic/dynamic models. This paper details the ‘knowledge acquisition module’ software and how it has been applied to construct a model of a large urban drainage system. The paper goes on to detail how the model has been linked with real-time radar data inputs from the MARS c-band radar.

Urban Drainage System

All the parts of an urban drainage system, i.e. the sewer system, the wastewater treatment plant (WWTP) and the river, should be integrated into one single model to assess the performance of the overall system and for the development of design and control strategies assisting in its sustainable and cost effective management. Existing models for the individual components of the system have to be merged in order to develop the integrated tool. One of the problems arising from this methodology is the incompatibility of state variables, processes and parameters used in the different modelling approaches. Optimisation of an urban drainage system, and of the wastewater treatment process in particular, requires a good knowledge of the wastewater composition. As important transformations take place between the emission from the household and the arrival at the treatment facility, sewer models should include these transformations in the sewer system. At present, however, research is still needed in order to increase our knowledge of these in-sewer processes. A comparison of the state variables, processes and parameters has been carried out in both sewer models (SMs) and activated sludge models (ASMs). An ASM approach is used for the description of reactions in sewer models. However, a difference is found in the expression for organic material (expressed in terms of BOD) and heterotrophic biomass is absent as a state variable, resulting in differences in processes and parameters. Reconciliation of both the models seems worthwhile and a preliminary solution is suggested in this paper.
