有利方面
清潔：水能為可再生能源，基本無污染。
運營成本低，效率高，技術成熟；
可按需供電；
取之不盡、用之不竭、可再生
控制洪水泛濫
提供灌溉用水
改善河流航運
有關工程同時改善該地區的交通、電力供供應和經濟，特別可以發展旅遊業及水產養殖。美國田納西河的綜合發展計劃，是首個大型的水利工程，帶動整體的經濟發展。

不利方面
生態破壞：大壩以下水流侵蝕加劇，河流的變化及對動植物的影響等。不過，這些負面影響是可預見並減小的。如水庫效應
需築壩移民等，基礎建設投資大
降水季節變化大的地區，少雨季節發電量少甚至停發電

Advantage
Aspect is clean: The hydro energy is the renewable energy source, does not have the pollution basically.
The operation cost is low, the efficiency is high, the technology is mature;
May demand the power supply;
Inexhaustible, inexhaustible, renewable control flood routing provides the irrigation water to improve the rivers shipping related project simultaneously to improve this local the transportation, the electric power for the supply and the economy, may develop the tourism and the aquaculture specially. The American Tennessee River's integrated development plan, is the first large-scale hydraulic engineering, leads the whole the economic development.

Disadvantage
Aspect ecological damage: The dam following current of water corrosion intensifies, rivers change and to zoology and botany influence and so on. However, these negative influences are may foresee and reduce. If the reservoir effect needs the build dams immigration and so on, the infrastructure invests the big precipitation seasonal variation big area, the few rain season power rate little even stops the electricity generation
