Lacustrine plain

The soil of the plain may constitute fertile and productive farmland due to the previous accumulation of lacustrine sediments; in other cases, it may become a wetland or a desert.

There are several reasons why drainage might occur, but in all cases the water in the lake is lost, leaving behind a level land of sediments.

Depending on geologic and climatic factors, the once-lake region may turn into a desert or wetland.

Glaciolacustrine plains form when the lakes in the continental ice sheets drain and leave the rocky debris within behind.

By analyzing the varve sequences and dividing them into the Matagami section and La Reine section, researchers were able to determine the time of occurrence for a major ice readvance event in the area and two drainage events in the lake.

Due to tectonic events, the uplift of crusts may occasionally lead to the formation of basins.

[3] Lacustrine plains formed by differential uplift can be found in multiple locations, and they are most commonly seen in Africa.

[7] Those lithofacies with little plant debris indicate a period of aridity and represent the last sequence of Chad formation where a lacustrine plain existed.

The remaining glacial materials also provide essential nutrients for crop growth and thus boost farm productivity.

A similar use of drainage areas and lacustrine plain can be found in a research done on the Congo.
