The purpose of the water conservancy industry is to comprehensively consider and reasonably arrange the control, development, and use of surface and groundwater resources, in order to achieve maximum safety, economy, and efficiency. The problems to be solved in water conservancy engineering planning generally include the following aspects: determining various governance and development goals according to needs and possibilities, selecting a reasonable engineering scale according to local natural, economic, and social conditions, and formulating a safe, economic, and convenient engineering layout plan for operation and management. Therefore, it is necessary to first conduct investigations and research on the hydrological and hydrogeological aspects of the river basin being treated or developed, and grasp the distribution status of water resources.
