Which Wadi Runs from North of Madinah to the Red Sea?

Wadi Al-Hamd, a seasonal watercourse in western Saudi Arabia, stretches about 400 kilometers from north of Madinah and empties into the Red Sea between Al-Wajh and Umluj governorates.

 The wadi runs northwest through Madinah and Tabuk regions before turning west toward the coast, according to the Encyclopedia of the Kingdom of Saudi Arabia, published by King Abdulaziz Public Library.

 The wadi's main tributaries include Wadi Al-Aqiq, Wadi Al-Jizl, Wadi Khaybar, and Wadi Al-Eis, whose waters converge in its channel during rainy seasons. These tributaries form part of a network of wadis feeding the main channel.
