Leprak River 3D Hydraulic Model Morphology Rasters

Nine modeling scenarios of riverbed morphology from a 3D physical hydraulic model for the Leprak River in Indonesia. The dataset consists of GeoTIFF raster files representing initial and flow-condition states, created by Santosa Sandy Putra to support a 2026 journal publication. It covers specific river reaches between diversion and consolidation dams.

Use Cases

• Analyze changes in riverbed elevation (Z-unit) between the Base scenario and Run1 (5 l/s flow) using GeoTIFF raster comparison.
• Compare morphological outcomes across Run2 to Run8 scenarios (all 9 l/s flow) to assess model sensitivity or consistency.
• Study spatial erosion/deposition patterns in the DD2_DD3 reach under the Run9 scenario (7 l/s flow).
• Validate 3D hydraulic model predictions against other data sources using the provided meter-unit planar and vertical coordinates.
• Assess the impact of different flow rates (5, 7, 9 l/s) on channel morphology for the specified Leprak River segments.

Strengths

• Contains results from 9 distinct hydraulic modeling scenarios (Base, Run1-Run9).
• Data is provided in standardized GeoTIFF format with explicit meter units for planar and vertical dimensions.
• Covers two specific river reaches (DD2_DD3 and DD3_KD3) for detailed spatial analysis.

Limitations

• The dataset is small at 13.6 MB, indicating limited spatial extent or resolution for the rasters.
• Row/feature count and specific raster resolution (e.g., pixel size) are not documented.
• Temporal coverage is not a historical series but a set of model snapshots from a single study period.
