water density
sorry i meant to put ebb and flow of rivers and tides
Are you asking about the precipitation in an estuary? The precipitation in an estuary varies according to where the estuary is located. An estuary is the point where a saltwater ocean, and a freshwater river come together. Precipitation changes will influence the ecosystem within the estuary. Estuaries are located all over the world, so you would have to find one estuary, and research the precipitation of that particular location.
Usually an Estuary. In these regions the salt content of the water varies and is commonly called "Brackish water".
It varies according to the type of freshwater biome
Salinity varies within the estuary and depend on other factors such as tides. Estuaries are essentially where freshwater from rivers, streams, etc, meet with saltwater from the ocean. The range of salinity within an estuary is typically between 0-25ppt, and that is between where the mouth of the river ends on to where the ocean begins. PPT stand for parts per thousand, just in case you did not know.
This is called the "mouth" of the river.A stretch of a river whose depth varies with the sea tides is called an estuary, and may contain brackish water or saltwater.
The average temperature of an estuary can vary depending on the location and time of year. Estuaries are typically influenced by both freshwater input from rivers and tidal movements from the ocean, leading to fluctuating temperatures. On average, estuaries can have temperatures ranging from around 50°F to 70°F (10°C to 21°C), but this can vary significantly based on local conditions and seasons. Monitoring temperature fluctuations in estuaries is important for understanding their ecological dynamics and impacts on marine life.
It varies, according to each zone, type, and conditions. The only exception might be underground aquifer's, or at least not directly.
Salinity in an estuary changes due to the mixing of freshwater from rivers and saltwater from the ocean. This creates a gradient where salinity varies with depth and distance from the river mouth, often leading to a stratified environment. Factors such as tidal fluctuations, river discharge, and seasonal variations influence these salinity levels, resulting in dynamic and diverse habitats. As a result, estuaries support unique ecosystems adapted to varying salinity conditions.

It varies, but usually the rivers freshwater mixing into saltwater.

The extinction rates of terrestrial and freshwater organisms varies per location. This is largely dependent on other growing and declining populations.
