Well..it's described as a narrow, fertile area which is about 3km wide and includes four fifth of the length of the Nile!! hope it helps :)
Upper Egypt, Arabic Qiblī Miṣr, also called Al-Ṣaʿīd (“The Upland”), geographic and cultural division of Egypt, generally consisting of the Nile River valley south of the delta and the 30th parallel N. It thus consists of the entire Nile River valley from Cairo south to Lake Nasser (formed by the Aswan High Dam). ;
Upper Egypt is the southern part of Egypt along the Nile River valley, extending from south of Cairo to Lake Nasser. It was historically significant for its fertility and cultural centers, contributing to the development of ancient Egyptian civilization. The area is named 'Upper' due to its higher elevation compared to 'Lower Egypt' to the north.
