“…Approximately 600 thousand feddans (~252,000 hectares) may be cultivated in this area, and this number is due to be increased in the future to ~1 million feddans (~420,000 hectares) irrigated using surface and groundwater [83]. Figure 10 shows the location of the TP [85,86]. The TP will ultimately create a new valley to the Nile River in the western desert of Egypt.…”

“…Toshka Bay is an off shoot of Lake Nasser in the direction of Toshka. When the water of Lake Nasser exceeds its storage level of 620 ft (~187 m) [84,87], the water is discharged into a man-made spillway canal (22 km long connection), which is used as a safety valve for Lake Nasser, upstream of the High Dam, and is connected to Toshka Bay via the Toshka Depression [84,86,87]. The Aswan High Dam is the largest constructed freshwater reservoir in the world [88].…”

Global climatic change intensifies the water crisis, particularly in arid and semi-arid regions. In this regard, the provision of enough water for irrigation is a serious dilemma because the agricultural sector consumes the largest amount of water (70% withdrawal and 90% consumption). In this review, we have summarized recent innovations that have emerged as unconventional techniques to supply adequate water for irrigation purposes. We present the principles and basics of seven approaches: the Sahara Forest Project (SFP), water extraction from the air (WEA), aquifer recharge, the treatment of marginal water using a magnetic field, desalination and wastewater treatment (DWT), electro-agric technology (E-AT), and the Toshka Project. The SFP is currently being utilized in Aqaba, Jordan, and DWT is considered a common practice worldwide, whereas some of these innovations are still under investigation to ensure their feasibility for large-scale applications, such as E-AT. The Toshka Project is considered a wonderful idea that utilizes the water stored behind the High Dam in Lake Nasser, Egypt. Several approaches have been adopted to reduce the amount of water being used for irrigation, as the current amount of freshwater is insufficient for the requirements of increased agricultural consumption, particularly in hot, arid, and semi-arid regions.

“…Due to organic and mineral pollution, obtaining data on the lake's bathymetry, e.g. using remote sensing methods 58 , 59 , may be impossible. It is not easy for such lakes to determine the surface area, especially the capacity, which is crucial from the point of view of industry needs.…”

Mining activity leads to subsidence troughs and permanent changes in water relations, like the formation of anthropogenic reservoirs. In the Upper Silesian Coal Basin (S Poland), their number is so high that the area is called an anthropogenic lake district. Any form of water retention, in the face of climate change, is valuable. However, the problem is the high variability of these lakes, making it challenging to estimate water resources. An example of this type of anthropogenic lake is the Brandka Pond in Bytom. An original method was proposed, consisting of two stages: reconstruction of the lake bottom relief based on the initial state of the area relief in 1994, i.e. at the beginning of the reservoir formation, and the land subsidence rate calculated for this area. Archival cartographic materials and DEMs from LiDAR data were used and processed in the open-source geoinformation software. Orthophoto maps and satellite scenes were also collected to determine changes in the extent of the pond from 1993 to 2019. Bathymetric data obtained in 2019 during sonar measurements on the reservoir was used to verify the calculations. The pond began to form in the early 1990s, and by 2019, it had reached an area of 178,226 m2, a maximum depth of 5.8 m and a capacity of 421,173 m3. The reconstruction method is accurate and suitable for lakes over 2 m deep, and the calculated capacity differs from the bathymetric data by 0.2%.
