By moving the waste from surface storage sites around big cities, the Energy Department eases nuclear nightmare scenarios _ an earthquake in Los Angeles, or a plane crash in Denver.

The injections began more than three decades ago as a safety precaution after the Kyshtym disaster and a string of other calamities drove home the dangers of surface storage, the papers said.

The reservoir for the region's Metropolitan Water District will nearly double Southern California's surface storage when it's finished in 1999 at a cost _ paid ultimately by water users _ of dlrs 1.8 billion.

The feeder takes advantage of large volumes of water when available from Northern California, depositing it in surface storage reservoirs, such as Diamond Valley Lake, and local groundwater basins for use during dry periods and emergencies.

This set of equations can be solved numerically at each runoff time step to determine how an inflow hydrograph to the LID unit is converted into some combination of runoff hydrograph, sub-surface storage, sub-surface drainage, and infiltration into the surrounding native soil.

WEAP is a model-building tool, used to create simulations of water demand, supply, runoff, evapotranspiration, infiltration, crop irrigation requirements, instream flow requirements, ecosystem services, groundwater and surface storage, reservoir operations, and pollution generation, treatment, discharge and instream water quality, all under scenarios of varying policy, hydrology, climate, land use, technology and socio-economic factors.
