1.0.1: Qt6-safe enum names in two fallback branches; tests no longer
in the plugin zip; a crossing candidate moved during review is snapped
from its new position; coverage check counts the other crossings of a
clustered stream (a road beside a river) as covered instead of
proposing new crossings on them; DEM uncertainty leaves a crossing
unassessed when the snap reaches another channel; user guide and
technical manual (docs/user-guide). 1.0.0: first stable release;
synthetic example DEM replaces the real-terrain example; tested on
QGIS 3.34 and 4.2. 0.27.1: end-to-end check on a synthetic site; DEM
uncertainty about 8x faster per realisation (one-pass longest flow
lengths); side-drain and mapped-drainage distances as parameters;
parameter order and help. 0.27.0: DEM uncertainty at crossings (Monte
Carlo with a correlated Gaussian DEM error: P10/P50/P90 and CV of
area, flow-path length, 10-85 slope and Kirpich Tc, lost-outlet and
switching shares; AW3D30 / FABDEM presets with sources, no silent
default). 0.26.0: land-cover scenarios (second land-cover raster
through the same lookups and soil groups: CN, C and soil-loss changes
per catchment); Graphical Modeler example
examples/qeht_corridor.model3. 0.25.0: Clip DEM to the road's
contributing area (coarse minimum-block routing, upstream of the road
buffer, margin, window read of the full DEM) for large DEMs; pipeline
option; clip_edge flag on catchments. 0.24.0: check against mapped
drainage (OSM, HydroRIVERS or a national layer): precision, recall and
F1 overall and per catchment, agreement per crossing, mapped rivers
crossing the road without a crossing, divergence reaches. 0.23.0: KMZ
(Google Earth: crossing cards, catchments, flow paths, road with
kilometre posts, coverage findings, relief overlay, legend and title
block) and XLSX workbook (design column order, units row, frozen
panes) exports, pure Python; Export package tool; pipeline exports/.
0.22.0: time of concentration by Kirpich, Kerby + Kirpich, SCS lag,
TR-55 segments and Bransby-Williams side by side with validity flags
and inputs (none chosen); P2 user value or raster with no default;
PROXY sheet n and Kerby N from land cover; table and report section.
0.21.0: Prepare DEM for hydrology (merge tiles, clip with a buffer,
bilinear or cubic to the WGS 84 / UTM zone of the extent centre
anywhere on Earth or any projected CRS, NoData override, input and
output audits, source tags read by the package); optional first step
of the pipeline. 0.20.0: side-drain siltation indicator per side along
the corridor (overland STI on the cells that drain to each side of the
road, relative classes, siltation flag on low-gradient stretches) in
Sample erosion along alignment and the package (layer corridor_sti).
0.19.0: approach-channel cross-section downstream of every crossing
(bed level, bank-full width and depth by break of slope, widths at bed
+ 0.5/1/2 m, side slopes, station-elevation list, quality flag; layer
xs_transects). 0.18.0: floodplain width indicator at large crossings
(profile and HAND, bed + 0.5/1/2 m); raster quicklooks (PNG + world
file + legend JSON, rasters index table) in the package and pipeline;
terrain under the run-report plan. 0.17.0: one-click hydrology
pipeline (fixed output folder, review stop, re-run from settings) with
an HTML run report and a catchment characteristics table; Run report
tool for any package; rainfall zones, mean annual rainfall and an R
estimate per catchment; R from rainfall in the erosion tool. 0.16.0:
drainage coverage check along the road (missing crossings, sag points,
flat stretches) with proposed crossings delineated in the package;
standalone coverage tool; relink keeps status. 0.15.1: .shp outputs
are real shapefiles; RUSLE factor range checks (class raster as C
refused); raster provenance tags; automatic merge of near-duplicate
crossings; candidate layers in Catchment characteristics. 0.15.0:
'Build design hydrology package' (was Build HEAS exchange package; id
unchanged); alignment ground profile; overland/channel split of the
flow path and basin shape indices; soils from any source (SoilGrids,
HWSD units, any polygon map, HYSOGs HSG, K rasters); curve number and
Rational C from land cover x HSG; overland STI, crossing deposition
indicator and approach/exit channel slopes. 0.14.0: erosion (WP-F) -
SPI, TWI, LS, RUSLE with source-tagged factors and LS-only fallback,
severity classes, corridor sampler, erosion block and crossing impact
score in the HEAS exchange; slope documentation (relief ratio is not a
Tc input), lfp_z_head_m / lfp_z_outlet_m / lfp_nonmonotonic. 0.13.1:
DEM QA warning for nearest-neighbour resampling; flat-method
sensitivity check per catchment (area under both methods, flag); ID
prefix applies to sequential IDs only. 0.13.0: Barnes 2014 is the
default flat method (WP-G benchmark, 80 Kenyan areas x ALOS/FABDEM vs
TauDEM, RichDEM, MAS, DDM); Barnes now identical to RichDEM; flats
touching the grid edge or NoData drain; hybrid removed; tested on QGIS
4.2.2 and 3.34. 0.12.0: vectorised core (3.6-5.4x faster), Barnes
flow-loop fix, hybrid flat resolution, memory estimate. 0.11.0: soil
parameters and USLE K (SOTWIS preset). 0.10.0: road crossing
candidates, burn crossings, renumber and relink. 0.9.0: HEAS exchange
package, stable outlet_uid, outlet-referenced 10-85 slope,
overlapping-catchment polygon fix. See CHANGELOG.md
