What is water balance analysis?

The water balance analysis reveals the percentages of precipitation made up by surface flow, evapotranspiration, groundwater recharge and the change of soil storage, all of which are considered useful to the further understanding of the hydrological processes in the Xitiaoxi catchment.

What is a water balance diagram?

A water balance chart compares the total water supplied to the site, the actual water consumed within all the water end uses in the site, and the total water leaving the site. This will help to identify areas of significant water usage and problem areas, including leaks and uncontrolled losses.

What is a positive water balance?

The water balance affects how much water is stored in a system. In wet seasons precipitation is greater than evapotranspiration which creates a water surplus. Ground stores fill with water which results in increased surface runoff, higher discharge and higher river levels. This means there is a positive water balance.

What are the various components of the water balance relationship?

Water balance. The cyclical movement of water between the atmosphere and the ground surface, considering precipitation, evaporation, and runoff (Whittow, 1984). Water balance equation. Equation presenting elementary parts of water balance: precipitation, evapotranspiration, and runoff, expressed as volume of water.

What is the difference between water budget and water balance?

A water budget reflects the relationship between input and output of water through a region. The water balance graph shows precipitation and potential evapotranspiration both as line graphs. Thus we have a direct comparison of supply of water and the natural demand for water.

Why is water balance important?

Water levels and mineral salts in the blood are controlled to protect animal cells by stopping too much water from entering or leaving them. The concentration of water and salts is the same inside and outside of the cells. If body cells lose or gain too much water by osmosis, they do not function efficiently.

What affects water balance?

The water balance looks at how the amount of precipitation compares with the water leaving the system as runoff or as evapotranspiration. This balance will change throughout the year and will be affected by the overall climate of the area near to the river.

What is World Water Balance?

Water balance is the ratio between water inflow and outflow estimated for different space and time scales, i.e. for the Earth as a whole, for oceans, continents, countries, natural-economic regions, and river basins, for a long-term period or for particular years and seasons.

What is negative water balance?

If fluid loss is greater than fluid gain (for example if the patient vomits and has diarrhea), the patient is said to be in negative fluid balance. In this case, fluid is often given intravenously to compensate for the loss.

What is water deficit?

The cumulative difference between the potential evapotranspiration and precipitation during a specified period in which the precipitation is the smaller of the two.

What is water balance in nutrition?

Water balance may be defined as the daily relation between the t. otztl amount of water entering the organism through the ingestion of liquids and food and the total output of water lost from the body by way of the kidneys, bowels, lungs, and skin.

What does it mean that the water cycle is in balance?

Balance in the water cycle means the average annual precipitation over Earth equals the amount of water that evaporates. the slope or steepness of a stream channel.

What is water or hydrological cycle?

The water cycle , also known as the hydrologic cycle, describes the continuous movement of water as it makes a circuit from the oceans to the atmosphere to the Earth and on again. Most of Earth’s water is in the oceans. The sun, which drives the water cycle, heats water in the oceans.
