This paper presents a general discussion of these topics, with a particular emphasis on three points: (i) the use of a direct recursive relation for building (semi) meanders (ii) the equivalence with a random matrix model (iii) the exact solution of simpler related problems, such as arch configurations or irreducible meanders.82 pages, uuencoded, uses harvmac (l mode) and epsf, 26+7 figures includedHigh Energy Physics - TheoryMeander, Folding and Arch Statisticstext
