Nelson Glueck (pronounced Glick), wrote Rivers in the Desert, a History of the Negev, in 1959. This book is still fascinating to read. You may find a few words in the following quotation that are rarely heard in our daily conversations. A wadi is a dry river (Nahal) or creek bed that is filled with water during the rain seasons in Israel.
Read Glueck’s description of the…
Terraces built across wadi beds to brake and exact tribute from the occasional winter and spring freshets, cisterns and reservoirs dug and plastered watertight to be filled from their meed [a now-archaic word meaning deserved share or reward] against the certainty of many a rainless day, and all the other devices perfected or invented by the Nabataeans and utilized and even expanded in instances by their immediate successors, could never accomplish for the countryside at large the miracles of rebirth that: a single rainfall over a wide area was able to perform. The grass and flowers fairly spring up after the first shower or storm, and the grim desert becomes a colorful garden overnight. It is as if a magic wand had been passed over the face of the earth. Flocks of birds suddenly make their appearance then, to sing and to swoop about in happy flight, and bands of gazelles and ibexes graze and cavort through the lush green. Camels and goats and sheep and their young wax fat. They drink their fill at pools of water collected in hollows, making it unnecessary for months on end to find other supplies for them. Springs flow more strongly, wells rise to their highest levels and the underground water is replenished in the wadi beds, there to remain long after the flowers have faded and the grass has withered and gone. Sturdy shrubs remain green all summer long because their roots tap the subsurface moisture. This is particularly true where the wadis are wide and shallow and terraced, with the result that the rain waters tend to sink into the ground. Otherwise, if unhindered, they race down narrow gullies and dry stream beds, stripping off the covering soil and gouging out for themselves ever deeper canyons. (Nelson Glueck.

I can’t begin to show you photos of every element mentioned by Glueck in this paragraph, but I will show you a couple of photos from the Wadi Zin in the Negev. First, here is a map from the from the wonderful collection on David P. Barrett’s Bible Mapper Blog.
Our first photo is a view of Wadi Zin a few miles south of Avdat in the Negev of Israel.
You will see evidence here of water having been at high levels. Various shrubs grow where the water remains the longest.
The next photo shows how the swift water cuts it way through the rocks.
