Almost at the end of its middle course, the Wadi Halu channel is partially obstructed by the collapse of large rocks from its left side, which has generated the deposit of earth, mud and other sediments, in the area immediately before the plug, forming a small flat and fertile space, used in the past

The lower course of the Wadi Halu receives the contribution of several small tributaries from the left, and has a very low gradient, with a bed formed almost exclusively by pebbles and other small and medium-sized boulders. There are very few trees, and in general the vegetation is scarce: only the

In the last kilometers, before its mouth into the Wadi Naqab, next to a residential area of the town of Saih Al Hurf, the sides of the wadi are formed mainly by sedimentary materials that have been accumulating for thousands of years and have been eroded by the sporadic avenues, offering a kind of

From the point of confluence of the Wadi Sal, the main channel of the Wadi Halu increases its flow and descends vigorously, generating – 900 m (3,000 ft) further down – a large dry waterfall, known as Wadi Halu Dry Falls, which in some points reaches a height of 70 m (230 ft),

The waters of multiple small sub-tributaries and secondary ravines or ravines that start from the southern slope of Jabal Sal end up in this main course of the Wadi Sal, which at its summit has a small plateau, cut by high cliffs facing north, and a slight inclination towards the south, which
