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
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 ...
Because of the cold California Current from the North Pacific Ocean and the fact that the storms tend to "steer" west, California has only been hit with three tropical storms in recorded history, a storm which came ashore in 1939 and dumped heavy rainfall on the Los Angeles area and interior deserts. The remnants of tropical systems will affect ...
Rain continues to fall in Southern California from an atmospheric river, raising the risk for additional mudslides with more than 120 reported so far in Los Angeles.
A stream hydrograph is commonly determining the influence of different hydrologic processes on discharge from the subject catchment. Because the timing, magnitude, and duration of groundwater return flow differs so greatly from that of direct runoff, separating and understanding the influence of these distinct processes is key to analyzing and simulating the likely hydrologic effects of ...
Tropical Storm Hilary blew past daily rainfall records across Southern California, ... L.A. County coast and metro area. Hollywood Reservoir: 4.92 inches. Beverly Hills: 4.8 inches.
The rainfall data can be either a user-defined time series or come from an external file. Several different popular rainfall file formats currently in use are supported, as well as a standard user-defined format. The principal input properties of rain gages include: rainfall data type (e.g., intensity, volume, or cumulative volume)
