Summary
This explorer layer adds wet-season and dry-season basin annotations so map readers can distinguish annual water volume from winter firmness and seasonal flow concentration.
Explorer label: Wet/dry season flow
Layer group: Hydrology and basin layers
Feature count: 8
Basin annotations focused on monsoon concentration, winter weakness, and dry-season implications.
What It Represents
This layer makes seasonality explicit on the map. Nepal's hydro advantage is physically real, but its value depends heavily on when water arrives. The annotations help separate annual volume from winter firmness.
How To Read It
Use it with storage shortlist, operating hydropower, and downstream markers. The key question is how much of the basin's energy or flow is wet-season heavy and what that means for dry-season deficits.
Coverage / Method
The layer is an eight-feature annotation layer exposed through the explorer map inventory. It covers basin-level seasonality notes for map reading and is intended to be used with hydropower, storage, and downstream hydrology layers rather than as a plant-level generation model.
Caveats
Seasonality annotations summarize complex hydrology. They should be read as planning context, not a replacement for plant-level generation modeling or climate-adjusted hydrological studies.
