stormsurge1d#

[Eta, x, maxsurgeheight, L] = stormsurge1d(h0, U10, m, dispout)

Description#

Calculate one dimensional storm surge using Dean Dalrymple (1991) method

Inputs#

h0: Deep-water depth in (m),
U10: 10-min averaged wind velocity at 10 meter above a surface in (m/s)
m=0;: Bed slope

Note: m=h0/L, where L is a length of the continental shelf in (m)
dispout=’no’;: Define to display outputs or not (‘yes’: display, ‘no’: not display)

Outputs#

Eta: Surge height along a x axis in (m)
x: Points on x axis in (m)

x=0 located at a far-end of the water boundary

x=L located at a coastline
maxsurgeheight: Maximum surge height at a coastline (x=L) in (m)
L: Length of the continental shelf in (m)

L=h0/m if m is not zero

L=50000 if m is zero (L=50000 meter for the hurricane Katrina)

Examples#

h0=42; %Example: h0=42 m for the hurricane Katrina
U10=40; %Example: U10=40 m/s for the hurricane Katrina
m=0.00084;
[Eta,x,maxsurgeheight,L]=stormsurge1d(h0,U10,m,'yes');
