The value in nautical miles of AS* . This corresponds 

 to DXI in Program SSURGE. 



Since in SSURGE the product, pAS* , is always computed in 

 the surge equations, we determine DXI in meters such that 

 V values are dimensionless , i.e.. 



DXI 



1852 -^ X AS* nmi x

The value in minutes at AT* . This corresponds to DETA 

 in Program SSURGE. 



Since in SSURGE, the product, vAT* , is always computed in 

 the surge equations, we determine DETA in meters such 

 that V values are dimensionless, i.e., 



DETA = 1852 -^ x AT* min x 

 nmi

The first value of S* in nautical miles. 



The number of water depths (fathoms) inputed from the sea- 

 ward boundary to the coast for determining distance as a 

 function of long wave traveltime. 



The number of points along XIDUM for determining n as 

 a function of arclength S 



XLAMDA Horizontal extent of the mapped region in units of x,y 

 space. 



XIDUM The particular value of C used in determining ri(S ) . 



SLMAP The chart scale relating distance in nautical miles to 

 distance in x,y units (i.e., nmi is equivalent to 51 

 units of length in x,y space) . 



G Acceleration due to gravity (feet-s~^). 



N4 The number of points used in determining 5 as a function 

 of arclength Sp . 



IRG The, number of expansion regions of SP(S*) or t(T*) .
