Solar Lake became isolated from the Red Sea as littoral sediments closed off an embayment between two rocky headlands. [2] [3] The saline waters of the Gulf of Aqaba that seep into Solar Lake are further concentrated by evaporation in the lake. [2] It is believed that in addition to losses from evaporation, there is a crack system at the bottom ...
Subsurface aeration seeks to release bubbles at the bottom of the water body and allow them to rise by the force of buoyancy. Diffused aeration systems utilize bubbles to aerate as well as mix the water. Water displacement from the expulsion of bubbles will cause a mixing action to occur, and the contact between the water and the bubble will ...
There are two main types of submerged diffused aeration systems for lagoon applications: floating lateral and submerged lateral. Both these systems utilize fine or medium bubble diffusers to provide aeration and mixing to the process water. The diffusers can be suspended slightly above the lagoon floor or may rest on the bottom.
TIBEAN systems exhibit a high degree of variability, catering to a wide range of applications. They offer oxygen inputs ranging from 1.5 to 60 kg/h, can be used at depths of 5 to 50 meters, and provide flow rates of 600 to 7500 m 3 /h. The utilization of deep-water aeration systems can serve various objectives, depending on the specific priorities.
Evaporation systems are also often evaluated by the water evaporation rate per unit area. When the energy is largely provided by sunlight, these are often evaluated with a solar efficiency, (), which is a thermal efficiency that compares incoming light energy to the enthalpy of vaporization. This is the same as the gained output ratio (GOR) in ...
The satellite images below, from the NASA, show the lake in April 2022, at left — when it was at 40% capacity — and then a little over two weeks ago, when the lake was a lavish 96% full.

Lake stratification is the tendency of lakes to form separate and distinct thermal layers during warm weather. Typically stratified lakes show three distinct layers: the epilimnion, comprising the top warm layer; the thermocline (or metalimnion), the middle layer, whose depth may change throughout the day; and the colder hypolimnion, extending to the floor of the lake.
