The works concerning of irrigation, drainage and reclamation engineering are storongly related to the landscape problem. However, there is no suitable method of evaluating the landscape altered by the works as well as by the civil engineerig works. This study deals with the problems on the design method of agricultural engineering works in which landscape is thought as one of the impotant matters. Design programs by using personal computer or computer of usual scale are developed for the 3 dimensional display of the related area on a cathode ray tube. A synthetic method of the image taken by a video camera and the image drawn by a personal computer is also studied. Procedures of proceeding a project with the consideration to landscape are proposed to encourage the engineers who are forced with the problems of landscape design.The perspective of geographical feature is displayed by the contour line or mesh data computed from the degitized contour line. The image of constructing structure is superimposed on the geographical feature of present condition on a screen of CRT. The data base system of landscape is also discussed here for the purpose of the coservation of natural beauty. Landscape design in the agricultural engineering works is discussed in three categories of rural planning, design of work and operation of project.
