double slope_function();
double cbasin();
// initializing classes: Subdivisions specs
//intitializing global variables
double edge_road =0;
double up_stream =0;
double down_stream =0;
double tbm =0.0;
//double culv_length =0;
double slope = 0.0 ;
char street_name[1001];
int min_culv = 15;
double up_strm_culv …
