Dissolved Load

Definition - What does Dissolved Load mean?

A Dissolved Load is a sediment mineral that contains ions, grains and geological sediments carried by a water stream. These ions and sediments are carried in the water stream primarily due to chemical weathering and are deposited wherever the water stream encounters an obstacle. When these ions finally reach the sea or ocean they provide the salty character to the water mass.

Petropedia explains Dissolved Load

Sedimentary load happens at various locations of a water stream because rock particles and dissolved ions are carried away in whichever direction the water is flowing to. Thus at various places, wherever an obstacle is rendered, these minerals are deposited and form a geological structure.

There are three types of sediment loads, i.e., dissolved load, bed load and suspended load. In the dissolved loads, as the name suggests, the minerals and ions gets dissolved in the water stream because of chemical weathering of rocks. Thus, the load in such case remains invisible. The primary constituents in the dissolved loads are-:

  • Bicarbonate ions (HCO3-)
  • Calcium ions (Ca+2)
  • Chlorine ions (Cl-)
  • Sodium ions (Na+2)
  • Magnesium ions (Mg+2)
  • Potassium ions (K+)
