The concept of water balance is discusse-d in the class lectures. Water balance is a very important concept in water resources. Environmental scientists and water resources professional will be calle-d upon to determine if the water balance (also know-n as water budget) of a watershe-d, a surface water system such as lake, or a groundwater system.
A well-formulate-d water balance enables planners and policy makers to make informe-d decisions and manage water resources sustainably. Additionaly, a simple water balance equation is use-d to determine the change in storage. Also, it determines water level by taking into consideration the inflows and outflows of the system. Conceptually, outflows from the systems are deducte-d from inflows into the system. This is to obtain the net change in storage. Also, in real life it is important to make sure proper units are used in the calculations.
A propose-d subdivision plans to collect stormwater runoff and divert it into detention basins. Generally, the developer submitte-d an application to the County proposing to create a new wetland as part of a mitigation plan. We need to determine if there will be a sufficient supply of water to maintain the functions of the new wetland.
The site is locate-d in the southwest of the U.S. and the weather is generally warm. The topography has a mild slope and the wetland is designed to help reduce the pollution that comes with the surface runoff. This is don-e by increasing the residence time and allowing the dissolve-d solids to settle in the wetland ecosystem. It also allows for phytoremediation to take place by the plants in the wetland.
