[Sample Input]


INPUT DATA:

1.  Name

1.1  Watershed/basin:  

Total number of input data in this section = 1.


2.  Selections

2.1  Units:           [Default: SI units (metric); U.S. Customary units currently unavailable].

2.2  Total simulation time (hr):           [Default: 36 hr].

2.3  NRCS 24-hr rainfall type:           [Default: Type I].

2.4  NRCS Antecedent Moisture Condition:           [Default: AMC II].

2.5  Output:           [Default: At basin outlet only].

Total number of input data in this section = 5.


3.  Topology

Please note that U = (R + 1)/2; likewise, R = 2U - 1. Otherwise, a fatal error will occur.

3.1  Number of upland watersheds U:      

3.2  Number of reach watersheds R:      

Total number of values in this section = 2.


4.  Upland watershed hydrologic data

Number of values in each box: U (See Input 3.1). Place a comma after each value; 150 viewable characters, 200 maximum.

4.1  Upland watershed numbers: An array of sequential numbers starting with 1 and ending with U [Example: 1,2,...,U].

4.2  Drainage area A (km2):

4.3  Precipitation P (mm):

4.4  Runoff curve number CN (AMC = II):

4.5  Hydraulic length L (m):

4.6  Average land slope S (%):

4.7  Average velocity [along hydraulic length] V (m/s):

Total number of values in this section = 6 U.


5.  Reach watershed hydrologic data

Number of values in each box: R (See Input 3.2). Place a comma after each value; 150 viewable characters, 200 maximum.

5.1  Topological number:

5.1.1  Tributary left/right indicator:

[Viewed from upstream to downstream:  Main = 0; Left = 1; Right = 2]

5.2  Drainage area A (km2):

5.3  Precipitation P (mm):

5.4  Runoff curve number CN (AMC = II):

5.5  Hydraulic length L (m):

5.6  Average land slope S (%):

5.7  Average velocity [along hydraulic length] V (m/s):

Total number of values in this section = 8 R.


6.  Channel reach hydraulic data

6.1  Reach:  (1) identifier, (2) baseflow Qb (m3/s), (3) length L (m), (4) slope So (m/m), (5) infiltration velocity Vi (m/s):
Number of values in this box:  5R    (R lines; 5 values per line). Place a comma after each value; 60 characters per line maximum.
To rerun, cut echo of input and paste into textarea box immediately below.

Echo of Input 6.1:

6.2  Properties:  (1) identifier, (2) No. of points Np, (3) Manning left, (4) Manning center, (5) Manning right, (6) X-limit left/center (m), (7) X-limit center/right (m):
Number of values in this box:  7R    (R lines; 7 values per line). Place a comma after each value; 100 characters per line maximum.
To rerun, cut echo of input and paste into textarea box immediately below.

Echo of Input 6.2:

6.3  Coordinates:  (1) identifier, (2) Np X-Z pairs (m):

Number of values in this box: R(1 + 2Np)    (R lines; 1 + 2Np values per line). Place a comma after each value; 160 characters per line maximum.
To rerun, cut echo of input and paste into textarea box immediately below.
