Factors that decrease downstream typically include reduced water flow, increased evaporation, and sedimentation. These can lead to lower water levels, diminished habitat quality for aquatic life, and decreased water temperature. Additionally, pollution and nutrient loading from upstream sources can negatively impact water quality downstream. Lastly, human activities such as dam construction and water extraction can significantly alter downstream ecosystems.

Why does depth and width increase downstream?
Depth and width of a river typically increase downstream due to several factors, including increased water volume from tributaries, reduced gradient, and erosion processes. As water flows downstream, it erodes the riverbanks and bed, widening and deepening the channel. Additionally, sediment transport and deposition can alter the river's shape, contributing to these increases in size. Overall, the combination of hydrological dynamics and geological processes leads to a broader and deeper river downstream.
What can you say definitely about the pressure about the opposite sides of an orifice when oil is flowing through it?
When oil flows through an orifice, the pressure on the upstream side (before the orifice) is typically higher than the pressure on the downstream side (after the orifice). This pressure difference is necessary to overcome the resistance to flow caused by the orifice's size and shape. As oil passes through the orifice, it accelerates, resulting in a decrease in pressure on the downstream side according to Bernoulli's principle. Therefore, the pressure on the upstream side will always be greater than the pressure on the downstream side during flow.
What factors make doubling time decrease?
The rate of growth and, unless the relationship is exponential, the frequency of each growth cycle.
What are the 3 factors that decrease crop productivity?
Too much, or too little: 1- Sunshine 2- Rain 3- soil fertilizer
What fo you call direct relationship in which two factors increase or decrease together?
A direct relationship in which two factors increase or decrease together is called a positive correlation. In this scenario, as one variable rises, the other variable also rises, and similarly, if one falls, the other falls as well. This relationship is often represented graphically with an upward-sloping line.
Why does volume of load decrease as you go downstream?
erosion :P
Does gradient of a stream increase or decrease downstream?
Decrease. The source of the river is usually in a mountainous area with a steep gradient.
Why does load particles decrease downstream?
Fine silt and mud are carried further downstream than heavier rocks and gravel. Which often results in muddy banks at the river mouth.
Does wetted perimeter decrease downstream?
No, it increases as there is more water in the channel.
Does a stream's velocity increase or decrease downstream?
A stream's velocity typically increases downstream due to the accumulation of water volume and slope gradient. This leads to higher flow rates and faster-moving water.
What makes the size of the pebbles smaller downstream?
As pebbles are transported downstream by the flowing water, they collide with each other and with other debris, causing them to break into smaller fragments. This process is known as attrition and leads to the gradual decrease in pebble size as they travel downstream. Additionally, smaller pebbles are also more easily carried by the current, allowing them to be transported further downstream.
What is the factors that may cause the decrease in ice-cream?
what is the factors that may cause a decrease in the demand of ice-cream
Why does the gradient of a river decrease downstream direction?
It doesn't decrease, it increases. It only apears to decrease because the lower course of a river is smoother. Because of waterfalls etc in the upper course, it appears to be going quicker when actually obstructions, although creating a splash, decrease spped.
What factors decrease urine output?
There are various factors which might decrease urine output. For example, if a person is dehydrated then they will urinate less.
Factors that increase or decrease maximal muscular performance?
Identify and contrast factors likely to increase or decrease maximal muscular performance.
What factors increase or decrease person's BMR?
Factors that can increase BMR are food and decrease it is the lack of food. You're welcome for the answer :D
What factors contribute to the decrease of both M1 and M2 money supplies?
Factors that contribute to the decrease of both M1 and M2 money supplies include a decrease in bank lending, a decrease in consumer spending, a decrease in government spending, and an increase in the demand for cash holdings.
