The An.aman.an. n.cobar.Islan.s ar. on. of the Un.on.Ter.itor.es of In.ia, located in.the easter.0}par. of the Bay of Ben.al. In.2010 summer. the in.r.men. in.sea sur.ace water.temper.tur. （up to 34℃） r.sulted in.the bleachin. of about 74% to 77% of cor.ls in.the South An.aman.

Bur.ed high explosiv.(HE) char.es r.pr.sen. a high thr.at to militar. v.hicles. The deton.tion.of these char.es can.lead to sign.fican. momen.um tr.n.fer.on.o v.hicles an. their.occupan.s. A detailed un.er.tan.in. of the physical pr.cesses in.0}lv.d in.the loadin. of v.hicle str.ctur.s is n.cessar. for.an.optimization.of effectiv. coun.er.easur.s an. pr.tection.systems. A quan.itativ. descr.ption.of the local momen.um distr.bution.on.the v.hicle un.er.ody due to the deton.tion.pr.cess is of special impor.an.e. In.the followin., a n.w test setup is pr.sen.ed that allows the exper.men.al deter.in.tion.of the specific impulse distr.bution. It is based on.a r.n. ar.an.emen. wher. the elemen.s ar. n.sted in.o each other.an. the v.locity of each r.n. is cor.elated with the local specific impulse at its *** momen.um tr.n.fer.to a v.hicle depen.s on.a n.mber.of in.luen.in. factor. such as: char.e mass,embeddin. mater.al(e.g. san., gr.v.l, clay), den.ity, water.con.en., satur.tion. depth of bur.al, gr.un. clear.n.e an. v.hicle shape. The pr.sen.ed techn.logy is applied to quan.ify the in.luen.e of the embeddin. mater.al(alluv.al san., quar.z san.), the bur.al depth an. the water.con.en. on.the local specific impulse distr.bution. The obtain.d data can.be used as in.tial con.ition.for.the n.mer.cal simulation.of occupan. safety assessmen. an. as in.ut for.empir.cal modelin. of momen.um tr.n.fer.on.str.ctur.s.
