Abstract

Palu Groundwater Basin can be assumed to have a post-earthquake deformation in 2018. To identify current state of Palu Groundwater Basin, modeling approach was conducted using GMS 10.4 (Groundwater Modeling System) with IDW (Inverse Distance Weighting), with the data used for the model was obtained from 41 boreholes. The results show that Palu Groundwater Basin aquifer geometry can be divided into 4 types. The unconfined aquifer consisting of Alluvium and Coastal Deposits (Qa) have an area 412,69 km², with 17,77 - 72.48 m thickness top layer have elevation 341 MSL (mean sea level) and bottom layer have elevation -2,29 MSL. Top aquitard consisting of Celebes Mollase of Sarasin and Sarasin (QTms) have an area 391,1 km² with 0.1 - 20,61 mm thickness top layer have elevation 268,52 MSL and the bottom of layer have elevation -20,06 MSL. Confined aquifer consisting of Celebes Mollase of Sarasin and Sarasin (QTms) have an area 351,98 km² with 20,58 - 86,51 m thickness top layer have elevation 268,42 MSL and bottom layer have elevation -40,67 msl. Bottom aquitard consisting of Granite and Granodiorite (Tmpi), Tinombo Formation (Tts), Metamorphic Complex (Km), Latimojong Formation (Kls) have an area 78,24 km² with 20,58 - 86,51 m thickness 3,01 - 4,1 m top layer have elevation 181,91 MSL and bottom layer have elevation -29,09 MSLKeywords: Groundwater, basin, modeling, geometry, aquifer

Abstract

Utilization of The Unmanned Aerial Vehicle (UAV) or Drone has brought revolution in digital photogrammetry. The feature matching on surface reconstruction or Digital Surface Model (DSM) are quickly finished. However, DSM doesn’t represent itself as a part of topography, that is why DSM should be converted into Digital Terrain Model (DTM). This research is to investigate the accuracy of UAV photogrammetry’s DTM  for hydraulic modeling purpose. This study has produced 4 sets of DTMs; 2 sets of DTMs with different grid resolution which are 2 cm & 40 cm, also the 2 other sets of DTM with extra fine nature algorithm and set of filtering parameters adjustment; bulge, offset, spike and standard deviation. Every DTM are validated by Ground Control Point (GCP) from Real Time Kinematic-Different Global Positioning System (RTK-DGPS) measurement. According to the validation, the adjustment of filtering parameters is the most accurate method with Root Mean Square Error (RMSE) of 6,17 cm for 2 cm resolution; and 5,22 cm for 40 cm resolution. Next, DTM UAV is used to estimate the flood water level from Synthetic Aperture Radar (SAR) Image detection with 46 flood images on Glane and Losser area, east part of Overijssel, The Netherlands, since October 2014 to December 2017, then validated with the insitu water level measurement and resulted RMSE 6,72 cm for set of UAV DTM’s 40 cm resolution with the filtering parameters adjustment. Therefore, this DTM UAV can be used as a topography parameter in hydraulic modeling, especially at the similar flat-surface terrain where this research have been conducted.  Keywords: UAV photogrammetry, SAR detection, DTM production

Abstract

Floods around the Bendung River in Palembang City have caused material and non-material losses. One of the reasons was the decreasing river capacity and backwater during the Musi River flood season, which is the Bendung River's outlet. This paper discusses the impact of adding a pump system to reduce flood impact. 1-dimensional and 2-dimensional numerical model using MIKE 11 and MIKE FLOOD were made to analyze the best measures. Various alternative scenarios were implemented in the model. Based on the modeling results, using the most optimal alternative, alternative 4 with 6 pumps of 36 m3/s and normalization of the Bendung River channel by 1 meter. The inundation area was reduced by 0.74 km2. Also, the maximum inundation height for the flood decreased by 0.6 meters, and the inundation duration was reduced by 8.5 hours. These modeling results can be a reference for managers and policymakers in managing flood events.Keywords: River channel normalization, pump system, numerical model, flood control, Bendung river

Abstract

Rawapening has an area of 2,667 acres, which now ceases to exist. This natural reservoir serves to preserve water, control flood, generate electric turbine, and raw water resource. The depth of this lake decreases 42 cm annually, with the shallowing could cause flooding of the lakeside and and reducing the water supply. This study finds the additional amount of structure and dimension of sabo dam to prevent hazards at each river: at Panjang 2 (B=20m H=2m, and B=25m H=2,5 m), at Galeh 2 (each of B=8m H=2,4m), at Legi 2 (B=10m H=2m, and B=25m and H=2,5m), at Parat 1 (B=13m H=2,7m), at upstream Sraten 1 (B=15m H=2,7m), at downstream Sraten 1 (B=15m H=2,7m), and at Kedungringgis 1 (B=12m H=1,8m). Existing materials are fine and rough sand. Using WaTEM/SEDEM, saboplan guideline by processing the designed capacity, it is estimated that each river’s potential annual yield (in tonnes): Panjang 86.221,8, Galeh/Torong 45.138,24, Legi 42.404,04, Parat 28.579,32, Sraten 25.988,76, and Kedung Ringis 6.955,2. Overall, sabo dam is designed to be a closed type dam located in inlet rivers of Rawapening. Sabo dam construction holds 25% of potential sediment. Collectively, it adds a control volume of 2.885 m3, from 11.539 m3 to become approximately to become 14.424 m3. To cope with sedimentation in Rawapening, the structural approachment (sabodam) should be combined with non structural approachment such as restoring land use in the upstream area for more optimal sedimentation control.Keywords: Sedimentation, rawapening, erosion, WaTEM/SEDEM

Abstract

Along with the significant increase of population in Bandung City at the moment, domestic wastewater management process must be considered to avoid river contamination, which one of the causes is domestic wastewater disposal without any prior management process. This study is located in Bandung City, which the research was performed in Research Center for Water Resources Office (PUSAIR) Bandung by involving residents of RW 09 Kelurahan Dago as respondents. The method used in this research is a combination of qualitative and quantitative methods. This study aims to analyze the sustainability of the domestic wastewater management process which is carried out using constructed wetlands by considering the economic, environmental, social, and technological aspects. The result shows that the sustainability value of the domestic wastewater management process conducted in the PUSAIR office is approximately 65.2% with the status of moderate sustainability. The detail result of each aspects is economic dimension 62.5%; ecological dimension 75%; social dimension 33.3%; and technological dimension 90%.Keywords: Domestic wastewater, Constructed wetlands, Surface flow techniques, Sustainability analysis
