The total length of the Wadi Madha is approximately , of which run in Emirati territory, and in Omani territory. Its
source is located within territory of the emirate of
Sharjah (
UAE), at an approximate altitude of , south-southeast of Jabal Daftah (). During its course, Wadi Madha crosses the border between Oman and the UAE four times, passing through the
enclaves of
Madha and
Nahwa before emptying into the
Gulf of Oman, south of Murbah/Sha'biyyāt Mirbah (Emirate of Fujairah, UAE). Shortly after, Wadi Madha flows north-northeast, between the channel of the small Wadi Hajar Bani Hamid and that of
Wadi Half, gaining a significant flow from its numerous tributary torrents, as evidenced by its characteristic
meanders. A branch of the Madha-Daftah road, which leads to the village of Hajar Bani Hamid, Wadi Madha receives the confluence of
Wadi Shis on its left, and continues its course towards the east, forming a small
gorge, shortly before the mouth of another of its important tributaries, the
Wadi Half, and the crossing with the border line of the
Nahwa (UAE) enclave. For , the Wadi Madha runs through the Nahwa enclave, also forming several meanders . On its banks it is common to find lush palm groves and fields of crops, especially around the old town of Nahwa. Also popular and very well known for tourism is the so-called
Al Nahwa Cave, located in the course of the wadi itself. The next UAE-Oman border is located at the exit of the modern part of the village of Nahwa, which, like the others, has no barriers or checkpoints, and does not require a visa or special requirements for crossing. The only indicators of the border are the flags and large murals with the portraits of the rulers of each country. Back in Oman, the Wadi Madha crosses an area with natural pools and two small villages with agricultural crops: Al Maksar and Sa'ad, the latter located just before the confluence of the Wadi Mayamt, one of the most affected by the construction of the Madha-Daftah road. The tail end of the extensive reservoir of the As Saruj dam reaches this point. Downstream from the dam and up to its mouth, the Wadi Madha passes through the most populated area of its entire course. In Oman: the village of Saruj, the historic village of Al Ghūnah, Al Ḩārah, Al Hawami, Al Anz̧ār (where the Wadi Sahanah / Wadi Sahna meets) and finally the city of
Madha / Sha'biyyāt Madḥah. Upon reaching the coastal strip, on the other side of the border, already in the
Emirate of Fujairah (UAE), the course of Wadi Madha has been partially channeled and diverted from its natural path, crossing the southern end of the city of Murbah / Sha'biyyāt Mirbah (Emirate of Fujairah), shortly before its mouth in the
Gulf of Oman. == Dams and reservoirs ==
