Alameda Creek Delft3D Flexible Mesh model: base setup (February 2023)
=====================================================================

What this is
This is the base model setup that Deltares USA and Deltares built for the study
"Hydrodynamic & Morphodynamic Modeling of Alameda Creek's Sediment Transport to
Evaluate Restoration Alternatives" (January 2024), prepared for the Alameda County
Flood Control and Water Conservation District. The grid and inputs were derived
from the San Francisco Bay-Delta Community Model (https://www.d3d-baydelta.org).

This package is the starting setup, not the calibrated runs in the report. The
report's calibration changed the initial sediment thicknesses (spatially varying
instead of uniform) and ran 2006-2019 with compressed and full time series and
seven bed-level scenarios. Those runs are not included here. See the report for
the final settings.

Contents
FlowFM.mdu               D-Flow FM master file (2D, written with kernel 1.2.167)
grid_version003_net.nc   Unstructured grid: South San Francisco Bay to Niles Canyon
bed_level_v4.xyz         Bed level samples (2006 District LiDAR, deepened low
                         points, CoNED for the Bay), read through Bathymetry.ini
frictioncoefficient.xyz  Manning roughness field (FlowFM.ext)
FlowFM_bnd.ext           Boundaries: Bay water level (Downstream_Bay.pli,
                         WaterLevel.bc, 2000-2019), daily discharge at Niles
                         (Upstream_Niles.pli, Discharge_daily.bc), clay and silt
                         inflow concentrations (Clay.bc, Silt.bc)
Discharge_15min.bc       15-minute discharge at Niles, alternative to the daily file
abstraction.pol, abstraction_0001.tim
                         Diversion from Alameda Creek to Quarry Lakes
FlowFM.mor, Engelund_Hansen.sed
                         Morphology and four sediment fractions (clay, silt,
                         sand, gravel; Engelund-Hansen transport)
*_IniSedThick.xyz        Initial sediment thickness per fraction (uniform in
                         this base setup)
observations_obs.xyn, FlowFM_crs.pli
                         Observation points and cross-sections

Coordinates are UTM zone 10N (meters). Bed levels are in meters; the report uses
NAVD88. Times are seconds since 2000-01-01. The mdu as delivered runs
2005-01-01 to 2008-01-01 with MorFac 1.
