From make_rivers():
  /* Formula to make the river density similar om different sized maps.
Avoids
     too few rivers on large maps and too many rivers on small maps. */
  int desirable_riverlength =
    map.riverlength *
    /* This 10 is a conversion factor to take into account the fact that
this
     * river code was written when map.riverlength had a maximum value of 
     * 1000 rather than the current 100 */
    10 *
    /* The size of the map (poles don't count). */
    map_num_tiles() 
      * (map.alltemperate ? 1.0 : 2.0 * ICE_BASE_LEVEL/MAX_TEMP) *
    /* Rivers need to be on land only. */
    map.landpercent /
    /* Adjustment value. Tested by me. Gives no rivers with 'set
       rivers 0', gives a reasonable amount of rivers with default
       settings and as many rivers as possible with 'set rivers 100'. */
    0xD000; /* (= 53248 in decimal) */

If map.alltemperature = 0 then desirable_river_length = 7
Something is wrong in this formula
when alltemperature = 1 rivers look normal.
