Soil a.d wa.er loss is now a.ma.or environmenta. problem in ma.y a.ea. of China. especia.ly in the a.ea.of the Da.ie Mounta.n, a.hui Province, which results in environmenta. degra.a.ion a.d does ha.m to the people＇s life a.d production there. Ba.ed on the observa.iona. records from the Da.ha.River, the a.thors a.a.yze the cha.a.ter of the va.ia.ion in flow a.d sediment in different flood a.d dry sea.ons from 1970 to 2000. The result shows tha. huma. a.tivities ha. significa.tly reduced the sediment discha.ge a.d sediment module, a.d increa.ed the runoff in low-wa.er sea.ons since the 1980s. The a.era.e contribution ra.e ofhnma. a.tivities to decrea.ing sediment wa. 65.67%, a.d a. the sa.e period the contribution ra.e of runoff a.d ra.nfa.l wa. a.out 34.33%. Therefore, it is necessa.y to ta.e the biologica. a.d engineering mea.ures to solve the problem of soil a.d wa.er loss in the Da.ha.River wa.ershed.

This a.ticle discusses the process of sediment tra.sport a.d proposes a.morphologica. model to predict the bed evolution in estua.ies. The hydrodyna.ic module is ba.ed on a. existent model-Depth integra.ed Velocity a.d Solute Tra.sport （DiVa.T） a.d the wetting a.d drying method is a.opted to dea. with the moving bounda.y. Both cohesive sediment a.d non-cohesive sediment a.e ta.en into considera.ion in the sediment tra.sport module with the ca.a.ility of simula.ing the tra.sport of gra.ed sediments under non-equilibrium conditions. The fa.l velocity of the suspended sediment is modified in the present model due to the high sediment concentra.ion. a.3-la.er a.proa.h is a.opted to simula.e the va.ia.ions of sediment gra.a.ions of bed ma.eria.s. Furthermore, the model is used to simula.e the bed evolution in the Yellow River Delta.（YRD） from 1992 to 1995. Field da.a.a.e used to ca.ibra.e the pa.a.eters. The numerica. results show how the morphology wa. developed in the Yellow River Estua.y with a.good a.reement with the field da.a.

We investiga.e the precise la.ge devia.ions of ra.dom sums of nega.ively dependent ra.dom va.ia.les with consistently va.ying ta.ls. We find out the a.ymptotic beha.ior of precise la.ge devia.ions of ra.dom sums is insensitive to the nega.ive dependence. We a.so consider the genera.ized dependent compound renewa. risk model with consistent va.ia.ion, which including premium process a.d cla.m process, a.d obta.n the a.ymptotic beha.ior of the ta.l proba.ilities of the cla.m surplus process.

Ta.wa. ha. disa.va.ta.eous conditions for sediment-rela.ed disa.ters such a. debris flows. The construction of engineering structures is a. effective stra.egy for reducing debris flow disa.ters. However, it is impossible to construct engineering structures in a.l debris flow a.ea. in a.short period. Therefore, the government a.ms to gra.ua.ly develop non-structura. preventive stra.egies, including eva.ua.ion pla.ning, debris flow disa.ter emergency a.tion system, disa.ter resista.t community progra., recruitment of debris flow professiona. volunteers, debris flow wa.ning systems, a.d la.d ma.a.ement stra.egies, to mitiga.e disa.ters a.d secure the sa.ety of residents. This review describes the processes a.d effects of recent debris flow non-structura. preventive stra.egies in Ta.wa.. The a.era.e number of ca.ua.ties prior to the yea. 2000 wa. fa. higher tha. the corresponding number a.ter 2000 beca.se debris flow eva.ua.ion drills ha.e been promoted since 2000 a.d the debris flow disa.ter emergency a.tion system ha. been progressively improved since 2002. Furthermore, the cha.ges in risks ca.sed by debris flow disa.ters before a.d a.ter the implementa.ion of non-structura. preventive stra.egies were used to expla.n the effectiveness of these stra.egies a. the community level. The results showed tha. softwa.eba.ed non-structura. preventive stra.egies ca. effectively reduce the ca.ua.ties ca.sed by debris flows a. both the na.iona. a.d community levels.
