The Institute for Rural Engineering, NARO (NIRE) aims to promote agricultural innovations with the development of technology that contributes to the achievement of a policy of "rural promotion" through prudent management of agricultural water and soil. Our recent research focuses on the development of technology that contributes to strategic renewal and management of agricultural irrigation facilities, disaster prevention and reduction in rural areas, preservation of regional resources for agricultural production, advanced paddy field management, biomass utilization, measures against the effects of climate change on farmland and water resources, and sophisticated environmental control of agricultural structures as well as many other areas. Moreover, we provide technical assistance with hazard and disaster countermeasures for farmland and agricultural facilities.

Utilization of tidal components to estimate the ease of groundwater passage

Published on 04 Aug 2017

image An simple method to estimate the permeability coefficient which indicates the ease of passage of groundwater in geological formation by utilizing the change of the groundwater level due to the strength of natural tides has been developed. In this method, it is possible to estimate the permeability coefficient of the stratum at the distance where the tidal fluctuation is transmitted based on a single pair of groundwater level data, and to survey a wide range of strata from a few observation points. With this method, available amount of groundwater resources in remote islands including water for agricultural use can be easily determined. Read more.


Diagnosing the safety of fiberglass reinforced plastic mortal pipe by measuring the strain

Published on 13 July 2017

image An efficient method for diagnosing the safety of fiberglass reinforced plastic mortar pipe(FRPM pipe), which is widely used for pipeline of agricultural water, has been developed by measuring the strain on the pipe.This method allows quantitative diagnosis of the safety against leakage of agricultural water pipelines due to extensive damage. In addition,it also facilitates identification of locally deformed sections of the pipe that have been missed out even before the occurrence of cracking and water leakage.Read more.
