Conclusion

In conclusion,

we have learnt different kinds of seawalls and their different purposes. (E.g curved seawalls, vertical seawalls and mound type seawalls)

we have analyzed the effectiveness and the ineffectiveness of different kinds of seawalls. (E.g a strong defence/costly, can be used for sightseeing/eyesore)

we have thought up problems that seawalls face. (E.g extreme events like tsunami, storm and rise in sea level)

we have found some examples of seawalls. (E.g Vancouver Seawall,Canada & Seagrove Bay,UK)

Even though seawalls are useful for our daily lives as they provide denfence and safety, seawalls still have some insurmountable problems such like extreme events and rise in sea level. Thus, we should choose correct seawalls to be built in appropriate places to exert seawalls' optimum efficiency and to make the best result.
