    dct:description """This digital dataset contains the segment and reaches for the surface-water network by model cell for the Central Valley 
Hydrologic Model (CVHM).  The Central Valley encompasses an approximate 50,000 square-kilometer region of California. 
The complex hydrologic system of the Central Valley is simulated using the U.S. Geological Survey (USGS) numerical 
modeling code MODFLOW-FMP (Schmid and others, 2006  ).  This simulation is referred to here as the CVHM 
(Faunt, 2009). Utilizing MODFLOW-FMP, the CVHM simulates groundwater and surface-water flow, irrigated agriculture, 
land subsidence, and other key processes in the Central Valley on a monthly basis from 1961-2003.  The total active 
modeled area is 20,334 square-miles.  The CVHM includes complex surface-water management processes.  The hydrology 
of the present-day Central Valley and the CVHM model are driven by surface-water deliveries and associated groundwater 
pumpage.  The Streamflow Routing Package (SFR1) is linked to MODFLOW-FMP to facilitate the simulated conveyance 
of surface-water deliveries. If surface-water deliveries do not meet the farm-delivery requirement, the FMP invokes simulated 
groundwater pumping to meet the demand.  The surface-water network represents a subset of the entire stream network in 
the valley.  Even so, it covers about 3,000 kilometers of surface-water and is simulated using 208 stream segments that 
represent 2244 stream reaches, with 43 inflows and 66 diversion locations providing 64 routed and 41 non-routed deliveries.  
Most of these inflows are regulated by dams and most of the deliveries are conveyed through an extensive canal network.  
The routed deliveries are conveyed through the simulated surface-water network, while the non-routed delivery conveyance 
typically occurs through small canals or diversion ditches and are not directly simulated. Much of the surface-water diversion 
and delivery information was compiled by the California Department of Water Resources (DWR) for 21 water-balance subregions 
(WBSs) covering the valley floor (C. Brush, California Department of Water Resources, written commun., February 21, 2007).  
The CVHM is the most recent regional-scale model of the Central Valley developed by the USGS.  The CVHM was developed 
as part of the USGS Groundwater Resources Program (see "Foreword", Chapter A, page iii, for details).""" ;
