Если смотреть с юридической и управленческой стороны, испарение воды часто связано не с техникой, а с правилами пользования водой и ресурсами.

1. Права на воду (water rights)

Во многих странах Африки действуют системы лицензий:

государство владеет водными ресурсами;

компания или община получает разрешение на забор определённого объёма.

Иногда дешевле испарить лишнюю воду, чем:

хранить её,

перераспределять,

нарушить лимит использования.

Это встречается в сельском хозяйстве и добывающих проектах.

2. Требования к сбросу воды

Законы по охране окружающей среды могут запрещать сбрасывать:

солёную,

химически загрязнённую,

шахтную воду.

Поэтому её помещают в испарительные пруды (evaporation ponds) — вода уходит, а загрязнение остаётся под контролем.

Это распространено в:

горнодобывающей промышленности,

нефтегазе,

переработке минералов.

3. Трансграничные водные соглашения

Многие реки проходят через несколько стран (например, бассейн Нил).
Иногда государства ограничены договорами по объёму воды, который можно удерживать или перенаправлять. В таких условиях локальные проекты используют испарительные бассейны вместо изменения русел или хранения.

4. Бюрократия и инфраструктура

В ряде регионов:

нет очистных сооружений,

нет канализации,

нет систем повторного использования воды.

С точки зрения регуляторов испарительный пруд — самый простой способ соблюсти формальные нормы.

5. Горнодобыча и литий/уран

В проектах добычи минералов (рассолы, урановые хвостохранилища) регуляторы прямо требуют испарительных систем для изоляции растворов.

---

Коротко: часто воду «испаряют» не из-за нехватки технологий, а потому что так проще выполнить закон, лицензии и экологические требования.

Если хочешь, могу разобрать конкретные страны — там правила сильно отличаются (например, в Намибия, ЮАР и Кения).

Good Morning #Canada
We still have 20+ rivers to highlight in this #CanadaRivers series and a couple of things stand out. We are now listing rivers that are close to 1,000 kms, and despite the size there are many I've never heard of. Add in several million lakes and you gotta agree that Canada is blessed with #Hydrology features.
The Thelon River, called Akilinik in Inuit, is #21 on our list and stretches 904 kms across northern Canada. Its source is Whitefish Lake in the Northwest Territories, and it flows east to Baker Lake in Nunavut, ultimately draining into Hudson Bay. It is fed by a watershed of 142,400 km2 but with a vertical drop of less than 400 metres over its length it is not suitable for hydroelectric development. The Thelon is one of the easiest tundra rivers to paddle, with a steady current, few rapids and no portages. It therefore is a destination for paddling vacations and tourists looking to experience Canada's north.

Good Morning #Canada
Today is a twofer of #CanadaRivers as we countdown the longest rivers in Canada.
#23 is the Red River which flows for 890 km, originating at the confluence of the Bois de Sioux and Otter Tail rivers between the U.S. states of Minnesota and North Dakota, flowing northward through the Red River Valley and continuing into Manitoba. It empties into Lake Winnipeg, whose waters join the Nelson River and ultimately flow into Hudson Bay. The river only falls 70 metres over it's length, so there are no hydroelectric opportunities, but because it drains a large watershed of 287,500 km2 it experiences significant spring volumes. This has led to calamitous (love that word) floods plaguing southern Manitoba for centuries. Flood canals and ice cutting (physical removal of large blocks every spring) have mitigated the risks but not eliminated them.
