0.4.0
- New algorithm: Basin morphometry. The full Horton-Strahler-Schumm
set
from one run, with the per-order table showing Strahler streams and
dataset reaches side by side, and the counts tested against what
Strahler
ordering allows. A bifurcation ratio below 2 and more than one stream
of
the basin's highest order are both impossible, and are now reported
instead of being handed back as numbers to interpret. Until now
morphometry was in the Python package but not reachable from QGIS.
- The plugin description no longer leads with "delineate". QGIS
already has
several delineation plugins, and the old wording put this one in that
queue while never mentioning morphometry at all, so a reader had no
reason to look further.
- Requires basinkit 0.4 or newer.

0.3.3
- Pairs with basinkit 0.3.3, which corrects channel_gradient_m_per_km.
Up to
0.3.0 it divided total basin relief by main channel length, which
reports
a fall the river never makes, because the highest point in a basin is
a
ridge top and not the head of the main stem. It is now read from the
bed:
the DEM is sampled along the main channel and the drop between its
ends is
divided by the channel length. On the Koshi that is 9.6 m/km, not
15.1.
The Basin statistics algorithm never reported this figure, so nothing
in
the plugin's own output changes; it matters if you called
morphometry()
from the Python Console or a script, where the old value should be
recomputed.
- Basin.morphometry() now checks its own stream counts. Two of the
checks
are impossibilities rather than oddities: an order-u+1 stream is
formed
where two order-u streams meet, so N(u) >= 2*N(u+1) and the
bifurcation
ratio can never fall below 2, and a basin with one outlet has exactly
one
stream of its highest order. Counts that break either are reported
rather
than returned as numbers.
- The plugin description now says plainly what this does that a
delineate-from-a-click plugin does not, rather than leaving a reader
to
work it out.

0.3.2
- Declares its pip dependency in the external_deps metadata field, so
it
shows in the External dependencies box on the plugin page.

0.3.1
- Fixed 16 Qt6 compatibility issues found by the plugin repository's
own
checker: every Qt and QGIS enum is now spelled with its full scope
(QgsWkbTypes.Type.Polygon rather than QgsWkbTypes.Polygon, and so on).
The scoped spelling works on both PyQt5 and PyQt6, so QGIS 3.28
onwards
and QGIS 4 are both covered by one code path, with no version guard.
- A test now scans the plugin for unscoped enums, so they cannot come
back.

0.3.0
The plugin version now tracks the basinkit package version, so it is
clear
which plugin goes with which package. No algorithm has changed since
0.1.0.
- Fixed: on macOS the "package missing" notice printed the QGIS
application
binary instead of an interpreter, so the suggested pip command opened
a
second QGIS window and installed nothing. A path is now offered only
once
it is verified to be a python executable, and there is a Python
Console
snippet that needs no path at all
- New icon: the b is drawn as a river basin with a dendritic stream
network
draining to a single outlet
- Pairs with basinkit 0.3.0, which adds Basin.morphometry() -- the
classical
Horton-Strahler-Schumm parameters -- to the Python API
0.1.0
First release.
- Delineate a basin from a canvas click, globally, via HydroBASINS
graph traversal or DEM flow routing
- Fetch DEM, land cover, soil, surface water, rivers and lakes clipped
to the basin
- Basin statistics: area, relief, mean slope, land cover fractions,
bounding-box efficiency
- Every algorithm runs in the Processing framework, so batch mode and
the Model Builder work
