| Benchmarks | |
| Tide gauge benchmarks | 0013: Dolphin point (32 28N, 34 52E), stainless steel, epoxy coated bolt on dolphin concrete capping platform. Elevation (H) of benchmark & local undulation (N) are 6.187m and 34.786m respectively (WGS-84 datum). |
| Benchmark relationships | Data are referenced to the zero of the land survey datum of Israel. Tide gauge zero (TGZ) = 18.00m below TGBM 0013. TGZ = 11.50m below Israel Land Survey Datum |
| Auxiliary benchmarks | 0012: Land control benchmark (32 28N, 34 53E), on top of water storage tank, H=16.132m, N=34.821m. Height difference from 0012 to 0013 (1991) orthometric diff.=9.945m, ellipsoidal diff.=9.980m; (1993) ellipsoidal diff.=9.983m. Three other precise levelling points in Israel Land Survey Network (0745, 0746 and 4462) are located nearby. |

| MSL method | Arithmetic average |
| PSMSL code | 1797 |
| Additional information | |
| Other relevant information | The dolphin used was loaded in 1980 with 900 metric ton for soil resistance testing & is estimated to have reached complete consolidation. The location of the Hadera station is estimated by some local geologiststo have been stable for the past 2000 years, on the basis of available geological data. |
| Nearest Met. station | Hadera Port, Israel |
