“…This kind of sustained research effort is essential. In addition, for water conservancy projects that have been or are going to be built, appropriate risk identification and evaluation analyses [39] should be carried out centered on the project itself and its potential impacts, so as to provide a basis for decision-making by project builders or planners.…”

Water conservancy projects occupy an extremely important status in human development history. Human cognition about water conservancy projects has been in constant evolution along with the changing relationship between humans and nature (water). Based on a literature review, this study provides a systemic summary of the evolution of the human need for water resources and of water conservancy projects, as well as the equilibrium between humans and nature (river and lake ecosystems). More importantly, the transformation of cognition concerning the governance of nature and river and lake ecosystems is reviewed. Taking the perspective of modern rationalism on water conservancy projects, four major changes in human cognition are identified. Further, the most salient water-related issues arising from China’s largest freshwater lake, Poyang Lake, are analyzed and the history and predicament of its governance are described. This is accompanied by a discussion on the countermeasures. Finally, based on the evolution of the human–water relationship and cognitive transformation concerning water conservancy projects, several suggestions are proposed for the planned construction of the Poyang Lake Hydraulic Project. The conclusions of this paper shed new light on the principles of water governance and water conservancy project construction in a new era that has witnessed a growing conflict between socioeconomic development and the water environment. Our suggestions are also valuable for the governance of Poyang Lake.

“…The Otsu River, which originates in the Katsuragi Mountains and flows about 68 km westward to Osaka Bay, is a river within Osaka Prefecture that consists of five branches. The river basin extends from 34 • 2 , and it includes three cities. The average annual temperature in the study area is 16 • C, and the average annual rainfall is about 1200 mm.…”

“…Therefore, for each unit of a flood risk assessment area, a risk curve that describes the exceedance probability distribution of loss should be estimated. Such spatial flood risk information is essential for various flood risk countermeasures, including risk controls: for example, improving safety and reliability of infrastructures [2] or risk financing: sharing risk using insurance or cat-bonds [3]. A flood risk assessment area can be affected by multiple flood sources: flooding from a main river, flooding from small rivers, inundation caused by heavy rainfall and drainage failure, even coastal flooding caused by storm surges, etc.…”

A key issue in assessing the spatial distribution of flood risk is considering risk information derived from multiple flood sources (river flooding, drainage inundation, etc.) that may affect the risk assessment area. This study proposes a method for assessing spatial flood risk that includes flooding and inundation in small-basin areas through multivariate design rainfall. The concept of critical rainfall duration, determined by the time of concentration of flooding, is used to represent the characteristics of flooding from different sources. A copula method is adopted to capture the correlation of rainfall amounts in different critical rainfall durations to reflect the correlation of potential flooding from multiple flood sources. Rainfalls for different return periods are designed based on the copula multivariate analysis. Using the design rainfalls as input, flood risk is assessed following the rainfall–runoff–inundation–loss estimation procedure. A case study of the Otsu River Basin, Osaka Prefecture, Japan, was conducted to demonstrate the feasibility and advantages of this method. Compared to conventional rainfall design, this method considers the response characteristics of multiple flood sources, and solves the problem of flood risk assessment from multiple flood sources. It can be applied to generate a precise flood risk assessment to support integrated flood risk management.

“…Such events exemplify the necessity of foresight and precautionary planning in the sense of risk and crisis management and the associated availability of technical and personnel resources for emergency water supply in the event of an emergency, crisis or catastrophe [15]. To be able to react appropriately to impairments, emergency measures must be planned and prepared in advance.…”

Drinking water supply is at the core of both, humanitarian action in times of crisis, as well as national policies for regular and emergency supply. In countries with a continuous water supply, the population mostly relies ingenuously on the permanent availability of tap water due to high supply standards. In case of a disruption in the drinking water infrastructure, minimum supply standards become important for emergency management during disasters. However, wider recognition of this issue is still lacking, particularly in countries facing comparably fewer disruptions. Several international agencies provide guideline values for minimum water provision standards in case of a disaster. Acknowledging that these minimum standards were developed for humanitarian assistance, it remains to be analyzed whether these standards apply to disaster management in countries with high supply standards. Based on a comprehensive literature review of scientific publications and humanitarian guidelines, as well as policies from selected countries, current processes, contents, and shortcomings of emergency water supply planning are assessed. To close the identified gaps, this paper flags potential improvements for emergency water supply planning and identifies future fields of research.
