Vijayawada FloodReSQ Layer Dashboard
Decision Context
The current dashboard packages all available model inputs and outputs into one review surface: river and Budameru water bodies, major canals, drainage, pumps, building footprints, roads, terrain readiness, Manning roughness, infiltration capacity, building obstruction, boundary-condition targets and flood hotspots.
The current run set uses historical hourly rainfall hyetographs plus Budameru inflow and river/canal antecedent sensitivity. Each completed scenario is available as a map toggle, with hydrographs, flood response, context layers and animation available in the same review package.

Boundary Location Layer
The boundary layer remains available as a map overlay in the Overview and Interactive Map tabs. This tab uses chart-first views so the forcing is readable at review scale.

Review Notes
The smooth view interpolates exported timestep depth to a continuous surface for presentation. Use the scenario dropdown to compare flood ingress, peak spread and egress timing across completed forcing states.
Use the layer toggles to bring roads, buildings, drainage, water bodies, pump links and hotspot targets into the movie view.
Scenario Comparison
This tab exists for comparing the completed runs numerically. Use it to see how rainfall family, river/canal state and Budameru inflow scaling change depth, wet area and stored surface water.

Ask questions against the current Vijayawada model evidence.
Use this tab when the map raises a question: worst wards, road exposure, Budameru contribution, drainage checks, scenario comparison, or what a field team should inspect first.
Scope & QA
This review build demonstrates how a Vijayawada flood decision-support workflow can combine local hydraulic context, public-domain rainfall and boundary forcing, adaptive FloodRESQ scenario outputs, and operational review layers in one stakeholder-facing interface. The FloodRESQ solvers are designed in-house by IIT Gandhinagar MIR Lab.
What It Demonstrates
Interactive review of flood depth, wet extent and velocity alongside city context, river/canal conditions, drainage assets, pumps, buildings, green/pervious areas and terrain-derived physics layers.
Current Scenario Set
18 completed historical-forcing scenarios covering observed Aug 2024 rainfall, a historical extreme rainfall case, normal/elevated/high river-canal states and Budameru inflow scaling.
Decision Use
Supports quick screening of likely inundation zones, flood hotspots, boundary-condition sensitivity, waterbody flow direction, and where field verification or operational attention should be focused.
Evidence Layers Included
- Hydraulic context: Krishna water bodies, extended Budameru, major canals, flow-direction arrows, pump and outfall exchange points.
- Urban exposure context: municipal boundary, wards, roads, building footprints, hotspots and ward-level response routine layer.
- Terrain and surface physics: DEM/DTM model surface, hydroconditioned terrain, slope, Manning/LULC partition, roughness, infiltration, soil-group proxy and building obstruction fraction.
- Forcing context: rainfall hyetographs, Budameru inflow hydrograph, river/canal stage templates and scenario-specific flood response curves.
Review Workflow
- Start in Overview to turn context layers on/off and inspect the city-scale map.
- Use Interactive Map for depth, extent and velocity overlays with cursor readout for location, approximate depth, velocity and wet duration.
- Use Hydrographs to understand rainfall, Budameru inflow, river/canal target stages and flood-response timing.
- Use Animation to review ingress and egress across the modeled event window.
- Use Scenario Comparison to compare completed runs by rainfall, river/canal state, Budameru inflow, depth, wet area and final volume.
Current Review Status
The current package is a stakeholder review build. It is designed to show that the layer stack, scenario toggles, hydrograph panels, cursor-based review, animation and flood-variable overlays work together as a coherent decision-support experience.
