Where groundwater accumulates

Border view: dashed black line follows the model’s KGZ/KAZ cell assignments, an approximate border at grid resolution. Burgundy indicates modeled head above ground, not observed inundation.

Annual storage gain

Million m³ per repeated forcing year. Blue: original outlets; orange: common seepage. These are adjustment cycles, not calendar years.

Storage is the change in water volume across both aquifer layers, expressed as an equivalent water depth over each cell. It is not water-table rise or flood depth. Positive lateral flow means net groundwater arriving from neighboring cells.

Clusters are connected cells in the highest tenth of positive accumulation, recomputed for each arm. They are diagnostic focus areas, not mapped geological units. The outer edge includes every active/inactive interface.

Aquifer properties remain unchanged in these runs. An upper head below its layer bottom is not a water table within that layer. No lateral groundwater exchange is prescribed at the outer edge; that assumption still needs physical qualification.
