The prospect for some research fields of river hydrology is given, such as the theory of runoff yield and concentration, drainage basin topography, river flood, river sediment, the thermal and ice regime of rivers, the utilization of river resources, water quality, river environment, and so on. The regularity of runoff yield and concentration under different climates and subsurface is further revealed; the hydrologic model of watershed of strong prediction ability is developed; numerical watershed is developed and applied; flood regularity under complex conditions is revealed and arithmetic methods of high accuracy are presented; arithmetic methods for sand yield, in which water dynamics is combined with river dynamics, will be practically used; the mechanism of sediment transport is also revealed; the thermodynamical and hydrodynamical mechanisms of the formation of ice and the change of ice regime are researched continuously to consummate the arithmetic model of ice slush; the movement mechanism of water flow containing pollutants is further revealed to consummate the model of water quality and to improve the accuracy of calculation. It is also pointed out that synthetic interdiciplinary means should be taken to explore the impact of human activities on the ecological system of rivers.%小流域综合治理在水土保持工作中的主要作用是：提高土地生产力，使土地结构趋于合理，具有明显的拦沙效果，减轻水旱灾害等.根据中国的具体情况，提出了几条对策，包括搞好农田基本建设，发展林果业，搞好植被建设和水土保持产业化，全方位综合治理等，以达到生态效益、经济效益、社会效益的互相统一.
