In order to prepare the interchange between and the unification of North and South Korea, it is needed to establish the development direction of irrigation reservoirs and formulate technological and political directions for preparing effectively against the demand of agricultural countermeasure information like the analysis of rural comprehensive development projects and the present state of agricultural land of North Korea. The purpose of this research is to construct the database of agricultural productive infrastructures and analyze the present state of irrigation reservoirs of the Yeseong River Basin in North Korea using SPOT-5 satellite imagery. As a result of the research, we were able to not only design classification items but establish method and precedure for producing thematic maps related agricultural productive infrastructure without on-site survey by analyzing present condition related to agricultural water of the basin. And we intend to provide basic data for analyzing suitabile locations of irrigation reservoirs in the basin by performing basin extraction, volume evaluation of the existing reservoirs, scale cultivative lands, benefit area fo the reservoirs, and the existing agricultural water system. In addition, we were able to understand the problem and limit in constructing the database related agricultural productive facilities.

This study attempted to simulate the flood discharge in the Duman River basin containing Hoeryong City and Musan County of North Korea where were damaged from Typhoon Lionrock on August, 2016. For hydrological modelling remotely sensed datasets were used to estimate watershed properties and hydrologic factors because the basin is ungauged where hydrological observation is not exist or sparse. For validation we applied our methodology and datasets to the Soyanggang Dam basin. It has not only similar shape factor and compactness ratio to those of the target basin but also accurate, adequate, and abundant measurements. The results showed that the flood discharge from Typhoon Lionrock corresponded to three to five years design floods in the Duman River basin. This indicate that the Duman River basin has a high risk of flood in the near future. Finally this study demonstrated that remotely sensed data and geographic information could be utilized to simulate flood discharge in an ungauged watershed.

Due to the various characteristics of urban river, rehabilitation project for natural river requires distinct alternative approach and selection method for each different types of river. In this study, naturalness of a river was used to establish such alternative for the business and rehabilitation plan for natural river. To assess the naturalness of a river, through AHP, designed to fit the environmental conditions in Korea, was employed. Furthermore, a method that conveniently compares and selects an alternative for rehabilitation plan for natural river by referencing Urban River Basin Enhancement Methods (URBEM) was proposed. After selecting the evaluation items for assessing the naturalness of the river based on the characteristics of the river, multiple alternatives were constructed and the naturalness of river for each of those alternatives were estimated. Comparing the estimated values has made the measurement of the natural recovery effect and the product of river rehabilitation plan for each alternative efficient. In conclusion, selecting the items for evaluating the naturalness of a river with respect to its characteristics was found to be effective for establishing the rehabilitation plan for natural river.

In general, the evaluation of water supply capacity is important factor to establish various establishment of water resource supply plan include water resource security and determination of dam's mass. But former researchs about estimation of water supply capacity were lack in continunity of evaluation basis, and didn't excute analysis on reliability criteria also. In this study, Nakdong river was selected for study basin, and then water supply capacity was analyzed by HEC-5 model using identical reliability criteria.

Tsurumi River Basin successfully started to prepare a Water Master Plan though a series of discussions by gathering all stakeholders in a hall. It began with setting five management targets namely, flood, low flow, natural environment, emergency use, and recreational use, followed by setting management goals by target as well as a one-sentence catchphrase for the Water Master Plan using a bottom-up approach. The author reviews this process and discusses the background of the success.
