GROUND_BOTTOM_PRESSURE_M | m | Optional: The additional head of higher areas outside the project causing water to flow in or out of the ground from deeper ground layers through the bottom boundary. | 0 |
This optionally fluctuating bottom pressure is added to the spatially defined Bottom pressure and resistance, to calculate ground bottom flow.
This attribute can be defined as values over time, using an array of values, defined as pairs of the start-time and its value from that point on.
