China's Baiheliang Ancient Hydrological Inscription in the #
Yangtze# River and #
Egypt#'s Nilometer on the Nile are under joint nomination for World Heritage status.
😆Baiheliang is a natural stone ridge in the Yangtze River north of Fuling District, #
Chongqing#. Measuring 1,600 meters in length and about 15 meters in average width, the ridge lies along the riverbed and remains submerged for most of the year, emerging only during the low-water season in #
winter# and #
spring#. Its inscriptions record low-water data for 72 years over more than 1,200 years, dating back to AD 764, making it an invaluable resource for hydrological research. #

Nilometers were used to measure the water level of the Nile. 🥽At least 20 once stood along the river. The one being jointly nominated with Baiheliang is located on #
Rawda# Island. Its main structure is a stone well about 10 meters wide and 13 meters deep, with an octagonal marble column standing at its center and marked with graduations indicating different water levels. The column bears inscriptions in #
Arabic# and Coptic recording water levels at different times.
Both the Yangtze River and the Nile are world-renowned cradles of civilization. 🌲Baiheliang and the Nilometer preserve valuable hydrological records, revealing cyclical patterns in agricultural production in the ancient civilizations of #
Asia# and #
Africa#. Jointly nominating these two well-preserved examples of hydrological #
heritage# from major river basins could help fill a gap in the World Heritage List, which currently has no comparable heritage sites representing ancient hydrological observation in major river basins. #
