Figure 13. Cumulative water supply over coefficient B calculated from water level by equation (9) and from precipitation by equation (10) for medium precipitation case. Calculation for a = 1 assumes that there is no storage of precipitation as snow on crater walls. Precipitation adjusted by factor Ba so that total precipitation for year matches that from known water-level change using B = 1.325 and po = 169.2 cm/y.

Figure 14. Cumulative water supply over coefficient B calculated from water level by equation (9) and from precipitation by equation (10) for medium precipitation case. Value for a chosen based on minimizing average absolute deviation between two calculated water supply curves. Precipitation adjusted by factor Ba so that total precipitation for year matches that from known water-level change using B = 1.325 and po = 169.2 cm/y.

Figure 15. Cumulative water supply over coefficient B calculated from water level by equation (9) and from precipitation by equation (10) for low precipitation case. Value for a chosen based on minimizing average absolute deviation between two calculated water supply curves. Precipitation adjusted by factor Ba so that total precipitation for year matches that from known water-level change using 1 = 1.325 and po = 169.2 cm/y.

Figure 16. Cumulative water supply over coefficient B calculated from water level by equation (9) and from precipitation by equation (10) for high precipitation case. Value for a chosen based on minimizing average absolute deviation between two calculated water supply curves. Precipitation adjusted by factor Ba so that total precipitation for year matches that from known water-level change using B = 1.325 and po = 169.2 cm/y.
