Stormwater Drainage Plot and Design QGIS 4 compatibility
QGIS 4 ready Active
Yes — Stormwater Drainage Plot and Design supports QGIS 4 (declared max version 4.99.0).
Plot TUFLOW pipe and pit layers as a long section, and design new stormwater pipe runs on it.
About
Dockable long-section plotting and design tool for stormwater drainage networks, built around TUFLOW 1d_nwk pipe and pit attributes. <br><br> <b>Plot</b> — Reads TUFLOW-style pipe and pit layers (ID, Type, US_Invert, DS_Invert, Width, Height, Number_of, Inlet_Type, Conn_1D_2D). Select the downstream pipe, trace upstream through the network (branching into one Path per tributary), and plot the ground line sampled from a DEM together with the conduit band, invert line and pits. Multiple pipe and pit layers are supported at once, with cross-layer connectivity. <br><br> <b>Interact</b> — Hover a pipe for its full attribute popup, hover the ground line to track that position on the map, and click a pipe in the chart to highlight and zoom to it, just like Identify. An optional crosshair gives a live chainage/elevation readout. Charts are rendered with Plotly inside the dock. <br><br> <b>Design</b> — Start a pipe layer carrying the design schema, then draw pipes with QGIS's normal digitising tools and snapping; every line becomes one pipe. Inverts are graded automatically from a minimum ground cover, pipe diameter and slope, and can be edited live in a table that stays in sync with the layer. Recalculate the whole chain after moving the alignment or changing the design settings. <br><br> <b>Export</b> — Send the plotted profile to CSV: paired X/Y series (ground, invert, obvert, pits) ready to chart, plus a per-pipe band table with chainage, levels, grade, cover and depth to invert for long-section drafting.
