Otherwise, the factor A can be determined from a data record of rainfall and runoff using the method explained below under non-linear reservoir. With this method the reservoir can be used as a black box model. Conversions 1 mm/day corresponds to 10 m 3 /day per ha of the watershed 1 L/s per ha corresponds to 8.64 mm/day or 86.4 m 3 /day per ha
The CALFED Bay-Delta Program, also known as CALFED, is a department within the government of California, administered under the California Resources Agency.The department acts as consortium, coordinating the activities and interests of the state government of California and the U.S. federal government to focus on interrelated water problems in the state’s Sacramento–San Joaquin River Delta.
Rain typically falls in California only during the winter and spring months, from October through May, with more rain falling on the northern half of the state than the southern. Approximately 75 percent of the total precipitation volume occurs north of Sacramento, while 75 percent of the total water demand is in the south.
is the initial abstraction ([L]; in), or the amount of water before runoff, such as infiltration, or rainfall interception by vegetation; historically, it has generally been assumed that =, although more recent research has found that = may be a more appropriate relationship in urbanized watersheds where the CN is updated to reflect developed ...
Watershed delineation is the process of identifying the boundary of a watershed, also referred to as a catchment, drainage basin, or river basin.It is an important step in many areas of environmental science, engineering, and management, for example to study flooding, aquatic habitat, or water pollution.

In hydrology, discharge is the volumetric flow rate (volume per time, in units of m 3 /h or ft 3 /h) of a stream. It equals the product of average flow velocity (with dimension of length per time, in m/h or ft/h) and the cross-sectional area (in m 2 or ft 2). [1] It includes any suspended solids (e.g. sediment), dissolved chemicals like CaCO
The first three months of 2022 have not been what the doctor ordered when it comes to easing drought concerns in California, particularly following a very wet December that resulted in a surplus ...
