The present work emphasizes on the changes in the Red Sea and Dead Sea mixed waters physical properties including: temperature, pH, dissolved oxygen, density, salinity and viscosity. It focuses on the impacts of changes in mixed water quality on the Dead Sea ecosystem and the current industrial activities. The pilot project site consisted of six water ponds (tanks) located next to Arab Potash Company point of intake about 100 m south of the Dead Sea shores. The Red Sea - Dead Sea water mixing was controlled and done based on the expected mixing ratios between Red Sea and Dead Sea waters to mimic the potential actual situation associated with Red Sea - Dead Sea project conduit. All measured properties of mixed water bodies in tanks 1 to 5 tend to behave differently from similar Dead Sea water (tank 6) properties. The properties variations depend on the rate of diluting the Dead Sea water by Red Sea water and rejected brine. The least altered physical properties were observed when the Red Sea concentrated brine was added to the Dead Sea water (tank 5). The obtained results show that transferring Red Sea water to Dead Sea would lead to dilution of Dead Sea brine and affects significantly the investigated mixed water physical properties. Water mixing project is expected to cease the halite precipitation phenomenon due to the development of stratification in the Dead Sea and halite dissolution. Based on the industrial needs for the Dead Sea brine with its current physical properties, it is recommended to add rejected brine only to the Dead Sea due to its minimal effect on physical properties variations.
本研究着重关注红海与死海混合水体的物理性质变化，包括温度、pH值、溶解氧、密度、盐度和粘度。它聚焦于混合水质变化对死海生态系统及当前工业活动的影响。试点项目场地由六个水塘（水池）组成，位于死海海岸以南约100米处阿拉伯钾肥公司取水点旁边。红海与死海的水体混合是基于红海与死海海水之间预期的混合比例进行控制和操作的，以模拟与红海-死海项目管道相关的潜在实际情况。1至5号水池中混合水体的所有测量属性往往与类似的死海海水（6号水池）属性表现不同。这些属性变化取决于红海海水和排出卤水对死海海水的稀释速率。当向死海海水中添加红海浓缩卤水时（5号水池），观察到物理性质变化最小。所得结果表明，将红海海水输送到死海会导致死海卤水稀释，并显著影响所研究的混合水体物理性质。由于死海分层现象的发展和石盐溶解，水混合项目预计将停止石盐沉淀现象。基于对具有当前物理性质的死海卤水的工业需求，建议仅向死海添加排出卤水，因为其对物理性质变化的影响最小。
