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.  +

Description: ''Note: See also the GEOMBEST+ Users Guide'', section 6<br> A minimum of four excel files are required to run a GEOMBEST-Plus simulation: an “erosionresponse” file, an “accretionresponse” file, a “run#” file, and a “tract#” file. If the simulation involves a single coastal tract then the files must be titled “erosionresponse”, “accretionreponse”, “run1” file and “tract1.” Quasi-3D simulations require additional files with sequential numbers. For example a simulation involving 3 tracts within a littoral cell also requires a “run2” and “run3” file as well as a “tract2” and “tract3” file. These files must conform to the strict format outlined in the following sections. If you are running multiple simulations of the same tract, you can use the multiple input and output files to keep track of your simulations. Caution: Note that the run# and tract# files will have the same name (tract1, run1, etc., see below) for all simulations and so attention to organization is critical. We suggest noting the changes made in each simulation in a readme file and then moving this file, as well as the input and output folders for each simulation, to a unique folder having an identifying name. Our convention, for example, has been to name each run with using the date and run number on that date as the identifier, e.g., the first simulation run on February 20, 2010 would be titled 02_20_10_01and would be placed in a folder having this name. '''6.1: “erosionresponse” file'''<br> '''6.2: “accretionresponse” file'''<br> '''6.3: “run#” file'''<br> '''6.4: “tract#” file'''  +

Input files for eSCAPE are based on YAML syntax. domain: definition of the unstructured grid containing the vtk grid filename and the associated field (here called Z) as well as the flow direction method to be used flowdir that takes an integer value between 1 (for SFD) and 12 (for Dinf) and the boundary conditions (bc: ‘flat’, ‘fixed’ or ‘slope’) time: the simulation time parameters defined by start, end, tout (the output interval) and dt (the internal time-step). Follows the optional forcing conditions: sea: the sea-level declaration with the relative sea-level position (m) and the sea-level curve which is a file containing 2 columns (time and sea-level position). climatic & tectonic have the same structure with a sequence of events defined by a starting time (start) and either a constant value (uniform) or a map. Then the parameters for the surface processes to simulate: spl: for the stream power law with a unique parameter Ke representing the The erodibility coefficient which is scale-dependent and its value depend on lithology and mean precipitation rate, channel width, flood frequency, channel hydraulics. It is worth noting that the coefficient m and n are fixed in this version and take the value 0.5 & 1 respectively. diffusion: hillslope, stream and marine diffusion coefficients. hillslopeK sets the simple creep transport law which states that transport rate depends linearly on topographic gradient. River transported sediment trapped in inland depressions or internally draining basins are diffused using the coefficient (streamK). The marine sediment are transported based on a diffusion coefficient oceanK. The parameter maxIT specifies the maximum number of steps used for diffusing sediment during any given time interval dt. Finally, you will need to specify the output folder: output: with dir the directory name and the option makedir that gives the possible to delete any existing output folder with the same name (if set to False) or to create a new folder with the give dir name plus a number at the end (e.g. outputDir_1 if set to True)
