Try this:
// Water
plane {
y, 0.27
//pigment { Blue }
texture {
pigment { rgbft <0.4,0.4,1.5,0.4,0.4>}//color red 0.4 green 0.4 blue 1.5 filter
.1 transmit 0.4 }
finish {conserve_energy
reflection {0.1,0.45 fresnel}
ambient 0.015
diffuse 0.26
}
normal {
bumps .5
}
}
interior{ior 1.34 fade_color rgb<0.64,0.64,1.5>fade_power 3 fade_distance 0.044}
//very short fade_diatance
}
Change the beach as follow:
// Beach
union{
sphere {
0
40
scale y*0.005
translate <10, 0.1, -7.5>
}
cone{<10,0.1,-7.5>,40,<10,-100,-7.5>,1000}
//this prevent the sharp edge of the flatened sphere from showing
texture {
pigment {
bumps
color_map {
[0 rgb <255/255, 204/255, 0>]
[1 rgb <255/255, 204/255, 0>/2]
}
}
finish {
reflection 0.0
ambient 0.15
diffuse 0.6
//refraction 1// ior 1.33
}
}
}
