Table 1 Weights assigned to (a) groundwater recharge, (b) extreme sea-levels, and (c) coastal erosion, which combined result in the suitability (low, medium, high) of eroding sandy shores for a growth of fresh groundwater resources by large beach nourishments.
From: Global potential for the growth of fresh groundwater resources with large beach nourishments
Suitability Class | a: Groundwater recharge | b: Extreme sea-level | c: Coastal erosion |
|---|---|---|---|
High (≥3) | >100 mm yr−1 (+2) | <1 m MSL (+2) | −1 to −0.5 m yr−1 (+1) |
Medium (−3 to 3) | 20–100 mm yr−1 (0) | 1–3 m MSL (0) | −3 to −1 m yr−1 (0) |
Low (≤−3) | <20 mm yr−1 (−2) | >3 m MSL (−2) | <−3 m yr−1 (−1) |
