L
S
Currently set up to modify the initial conditions (run time, wave height, current velocity, current dir., etc.) from within the source code. +
C
DEM +
R
C
DEM as ascii grid (output from arcGIS),
Rainfall data as a space separated ascii file (straightforward list), Inputs of water/sediment in an ascii file. Other single value parameter inputs for grainsize, flow parameters, slope processes etc.. +
H
DEM raster and Hexagon shapefile, stream segment threshold +
F
G
DEM, land-use/land-cover, stream channels, precipitation, soils, aquifer maps. These index maps are used to classify catchment parameters related to overland/channel flow, soil/aquifer hydraulic properties, soil erodibility, contaminant loadings, etc. Model setup is greatly enhanced by the use of the US Dept. of Defense Watershed Modeling System (WMS), which serves as an interface between GSSHA and Arc/Info +
DEM, rainfall, temperature +
N
DEM: A DEM in *.flt binary format (as generated by ARC GIS)
Search Window Radius: The distance around the centre cell in which to evaluate the means (in pixels).
Similarity Window Radius: The distance around neighbouring cells over which to calculate means (in pixels).
Degree of filtering: The weighting for the gaussian kernel controlling the strength of filtering and therefore the decay of weights as a function of distance from the centre of the kernel. +
L
Daily average solar radiation for location (at surface). +
W
Daily climate input (temperatures, precipitation depth, duration, Tp, Ip, wind info); slope input (distance downslope, slope at points, profile width, aspect); soil input (infiltration & erodibility parameters, soil layer depth, texture, organic matter, CEC, etc.; cropping/management input - plant growth parameters, residue decomposition parameters, tillage operation parameters, residue management parameters, dates of operations (planting, harvest, tillage, residue management, etc.); irrigation input - type of irrigation, date(s) of irrigation, application rates, etc.; channel parameters input - channel shape, width, slope, roughness, etc.; impoundment parameters input - type of impoundment (1. Drop Spillway 2. Perforated Riser 3. Culvert 4. Emergency Spillway or Open Channel 5. Rock Fill Check Dam 6. Filter Fence / Straw Bales / Trash Barriers 7. User Specified Stage-Discharge Relationship, parameter inputs specific to each impoundment type; watershed structure file - describes how all hillslopes, channels, and impoundments in a watershed are linked. +
D
Daily precipitation, daily evapotranspiration, and short-interval precipitation are required. Short-interval discharge is required for the optimization option and to calibrate the model. These time series are read from a WDM file. Roughness and hydraulics parameters and sub-catchment areas are required to define the basin. Six parameters are required to calculate infiltration and soil-moisture accounting. Up to three rainfall stations may be used. Two soil types may be defined. A total of 99 flow planes, channels, pipes, reservoirs, and junctions may be used to define the basin. +
H
Data needs for HSPF can be extensive. HSPF is a continuous simulation
program and requires continuous data to drive the simulations. At a minimum,
continuous rainfall records are required to drive the runoff model and
additional records of evapotranspiration, temperature, and solar intensity
are desirable. A large number of model parameters can be specified although
default values are provided where reasonable values are available. HSPF is
a general-purpose program and special attention has been paid to cases where
input parameters are omitted. In addition, option flags allow bypassing of
whole sections of the program where data are not available. +
