SWMM 5.2.2 Code for LID Process in LID.h

 This code defines a struct named "TLidProc" which represents the LID (Low Impact Development) process, which is a generic LID design per unit of area.

The struct contains the following fields:

Field	Type	Description
ID	char*	identifying name of the LID process
lidType	int	type of LID (corresponds to an enumerator from the "LidTypes" enumeration)
surface	TSurfaceLayer	surface layer parameters
pavement	TPavementLayer	pavement layer parameters
soil	TSoilLayer	soil layer parameters
storage	TStorageLayer	storage layer parameters
drain	TDrainLayer	underdrain system parameters
drainMat	TDrainMatLayer	drainage mat layer
drainRmvl	double*	underdrain pollutant removals

The "ID" field is a string that can be used to identify the specific LID process. The "lidType" field is an integer that corresponds to one of the enumerators from the "LidTypes" enumeration. This allows the code to determine the specific type of LID process represented by this struct.

The "surface", "pavement", "soil", "storage", "drain" and "drainMat" fields are structs themselves and they contain specific parameters for the surface layer, pavement layer, soil layer, storage layer, underdrain system and drainage mat layer respectively. The "drainRmvl" field is a pointer to an array of doubles, which represent the underdrain pollutant removals.

This struct is used to store all the information about a specific LID process and can be used to design and simulate the performance of the LID unit. The struct also contains information about different layers of LID unit, like surface layer, soil layer and storage layer which helps to simulate the performance of LID unit.
