presented by the country’s geographical features 可以看成是which are presented by the country’s geographical features 。by后面是接的动作发出者。
Many of the problems found solutions 这是主句

Many of the problems 是主语,presented by the country’s geographical features 是主语的定语,found 是谓语,solutions in innovative engineering projects是整个宾语

句子的主句是Many of the problems found solution

这里present是及物动词,presented by...是过去分词作定语从句,此处表被动,翻译为:由国家的地理特征引发的许多问题
