WMS:WMLibSubBasin

Description

The public class SubBasin class manages hydrologic information for a sub-basin attached to an outlet point in the hydrologic tree.

Functions

• public SubBasin(WMLib.OutletPoint a_basinOutlet, double a_area, double a_timeConc, WMLib.RainfallData a_rainfallData, double a_curveNumber, string a_name)

This function is the constructor function for an instance of a SubBasin class. When creating a SubBasin, pass this function the following information: the outlet the sub-basin will be attached to (a_basinOutlet), the sub-basin area (a_area, square miles), the sub-basin time of concentration (a_timeConc, minutes), the sub-basin rainfall data (a_rainfallData), the sub-basin NRCS curve number (a_curveNumber), and the sub-basin name (a_name). A sub-basin will be created with the specified name and attached to the specified outlet point. The time of concentration is converted to a lag time using the SCS equation and is used in the HEC-1 SCS Unit Hydrograph method for computing a hydrograph for the sub-basin. See the example in the introduction as an example of how this function is used.

• public System.Collections.Generic.List<TimeSeriesPoint> GetHydrograph()

After HEC-1 has been run, you can get the hydrograph at a sub-basin by calling GetHydrograph, which returns a list of time series points.

• public double GetPeakFlow()

After HEC-1 has been run, you can get the peak hydrograph flow for the sub-basin by calling this function.

• public System.DateTime GetPeakTime()

After HEC-1 has been run, you can get the time of the peak hydrograph flow for the sub-basin by calling this function.

• public void SetArea(double a_area)

Set the area (square miles) for the sub-basin by calling this function.

• public void SetCurveNumber(double a_curveNumber)

Set the curve number for the sub-basin by calling this function.

• public void SetRainfallData(WMLib.RainfallData a_data)

Set the rainfall data for the sub-basin by calling this function. See the SubBasin constructor description and the RainfallData class for more information about the RainfallData.

• public void SetTimeConc(double a_timeConc)

Set the time of concentration (minutes) for the sub-basin by calling this function.

Accessible Member Variables

• public double m_area { get; private set; }

The area of the sub-basin, in square miles. You are allowed to get the value of this variable, but not to set it. Use SetArea to set the area or set it in the SubBasin constructor.

• public double m_timeConc { get; private set; }

The time of concentration for the sub-basin, in minutes. You are allowed to get the value of this variable, but not to set it. Use SetTimeConc to set the time of concentration.

• public double m_curveNumber { get; private set; }

The sub-basin curve number. You are allowed to get the value of this variable, but not to set it. Use SetCurveNumber to set the curve number.

• public string m_name { get; private set; }

The name of the sub-basin. You are allowed to get the value of this variable, but not to set it.
