Tidal creek

[1] Thus, it has variable salinity and electrical conductivity over the tidal cycle, and flushes salts from inland soils.

Tidal creeks are characterized by slow water velocity, resulting in buildup of fine, organic sediment in wetlands.

[a] On the India and Pakistan borders, the term also applies to the salt water inlets enclosed by mangroves.

It includes a series of indentations within a wide spectrum of sizes (width, length, and depth) and with at least two levels of inundation.

A tidal course creates a system for its ecosystem that circulates water, sediments, organic matter, nutrient, and pollutants.

[6] A tidal course is essential to the surrounding flora and fauna because they provide protection, nutrients, a place to reproduce, and a habitat for juvenile species before they go into the ocean.

Tidal creeks deposit sediment in a process called accretion, during the flood tide, which can maintain a flat plain by counteracting sea level rise or land subsidence.
