Multimedia covers a wide range. In general, digital audio production, animation video production, website production, and even game development can all be attributed to multimedia. The definition of multimedia narrowly defined, that is, the project with interactive program development as the main object of this paper, such as interactive CD production, touch screen presentation production, etc. Of course, there will still be a lot of content related to graphic design, animation, video processing, audio production and so on. The application of multimedia technology in water conservancy and hydro-power engineering is characterized by a variety of media means to represent the design, construction process and post-construction scene of water conservancy and hydro-power projects and to simulate the phenomenon in the project, such as the performance of water conservancy and hydro-power projects. Hub layout, structure of main buildings, dam flood discharge, rubber dam dam overflow, sluice dispatching process, ship lock crossing process, etc. In the water conservancy and hydro-power project, computer multimedia technology has been widely used from the general design proposal to the entire pivot project demonstration system. This paper mainly introduces the design and development of the multimedia demonstration system for water conservancy and hydro-power projects.

多媒体涵盖范围很广。通常，数字音频制作，动画视频制作，网站制作甚至游戏开发都可以归因于多媒体。多媒体的定义狭义地定义了，即以交互式程序开发为主要项目的项目，例如交互式CD的制作，触摸屏演示的制作等。当然，仍然会有很多与之相关的内容。平面设计，动画，视频处理，音频制作等。多媒体技术在水利水电工程中的应用具有多种媒介手段，可以代表水利水电工程的设计，施工过程和施工后的现场，并模拟工程中的现象，例如水利和水电项目的绩效。枢纽布局，主体建筑物结构，大坝泄洪，橡胶坝泄洪，水闸调度，船闸穿越过程等。在水利水电工程中，计算机多媒体技术已从总体设计方案中得到广泛应用。整个枢纽项目示范系统。本文主要介绍水利水电工程多媒体演示系统的设计与开发。从总体设计方案到整个枢纽项目演示系统，计算机多媒体技术已得到广泛使用。本文主要介绍水利水电工程多媒体演示系统的设计与开发。从总体设计方案到整个枢纽项目演示系统，计算机多媒体技术已得到广泛使用。本文主要介绍水利水电工程多媒体演示系统的设计与开发。
