Suitaiology

Keynote I: There are major defects in the traditional understanding of water resources.  
Keynote II: Existing water science is deficient to deal with climate change.  
Keynote III: Suitaiology should be a good solution.

       Extreme climate change with increasing frequency and magnitude has globally caused great damage and loss through extreme droughts, floods and other secondary disasters during the past years. Especially, the most affected are agriculture and ecology. Floods and secondary disasters such as soil loss, mudslides, and landslides often cause losses to farmland, houses, and life. Extreme droughts cause water shortages for humans and livestock, crop failure, forests withered, and desertification. Facing disasters, traditional measures for flood or drought often fail. Traditional water science regards the surface and underground water produced by precipitation as the total quantity of water resources. However, in the current situation, floods are actually just the source of disasters rather than water resources. In the extreme drought period, the so-called "water resources" has lost its meaning. For a long time, human have been plagued by droughts and floods. It highlights the major shortcomings of traditional understanding of water resources and the deficiency of the existing water science to adapt climate changes.

       
In order to meet the challenges of climate change and sustainable development of human society, especially agriculture, Referring to the idea of ecology, we jumped out of the research trap of taking water as the main body, focused on the interaction between water and other subsystems in the large-scale system of “Water-Human-Natural Environment" (WHNE) and the dynamic tendency of this interaction, or water situation, and coined Suitaiology, a new branch of water science.  

Leng-Broad-High-Deep (LBHD):  Our guiding philosophy.  

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

In scientific seeking, we have a guiding philosophy: Leng-Broad-High-Deep (LBHD).  

      Long:  To do any work, we must first determine its long-term significance and goal, and then from it set medium-term and short-term work objectives, tasks and plans to achieve the long-term goal. Water is the guarantee of life on earth. Either too little water or too much water can cause serious disasters and damage. The approaches of available climate change adaptation and disaster risk reduction strategies includes hard (structural) and soft (policy instruments) Traditional and current efforts in committee In order to meet the challenges of climate change and the sustainable development of human society (especially agriculture), it is an extremely urgent for scientists and human society to understand how to pursue good and avoid bad for water and put it into practice.  

      Broad:  To solve any problem, we must have a broad vision. Modern science mechanically divides scientific research into specialties, and there are few masters who grasp the overall situation. Under the guidance of the traditional specialistic water sciences, it is inevitable that one will lose the other. While dealing with the crises of drought, flood and their induced geological, ecological and social disasters, we must also comprehensively consider the sustainability of ecological security and economic development.  

      High:  Making a strategy or work plan requires a mastery of the whole, which means that we must view, understand and grasp the whole from a higher horizon, that is, we should examine the object and its related elements as a whole system. The problems of water are not only to deal with less or more water, but also how to comprehensively eliminate the crisis of drought, flood and their induced geological, ecological and social disasters, and ensure ecological security and sustainable economic development. Therefore, it is essential to jump out of the trap of separately -thinking about drought or flood, integrate the goals of eliminating the crisis of drought, flood and their induced disasters and ensuring ecological security and sustainable economic development into a larger system of “Water-Human-Natural Environment” (WHNE), and develop our thoughts from the height of larger system.  

      Deep:  The key to solve problems successfully is to grasp the core. With reference to the idea of ecology and through the appearances of the form, state and quantity of water, we focus on the interaction between water and other subsystems in the WHNE system and the dynamic change trend of this interaction, namely water situation, and establish hydrology, which is a new branch of Water Science.

Definition:  The study of the interactions between water and other subsystems in the large-scale system of “Water-Human-Natural Environment" (WHNE) and the dynamic tendency of this interaction, or water situation.  
Mission:  Precisely and comprehensively pursue good fortune of water such as water resources and avoid disasters of water such as drought, flood and their corresponding derived geological, ecological and social disasters disasters.

      Suitaiology (rom Chinese and Japanese: 水态/水態（shuitai/suitai）, meaning "water dynamic status"; and from Greek λόγος, lógos meaning “study of") is the study of the interactions between water and other subsystems in the large-scale system of “Water-Human-Natural Environment" (WHNE) and the dynamic tendency of this interaction, or water situation. Natural environment includes physical geography, geological conditions, biological environment, climate change, etc.

      Suitaiology, a new branch of water science, focuses on how to lead water to adjust its situation to remove its hazards and become a resource so that conform to the system situation which core is economic, social and ecological carrying capacity and sustainable development.

      Suitaiology regards water management and its service objects, environment and conditions as a dynamic system that restricts and promotes each other, studies the natural situation of water, the impact of human intervention on the water situation, the negative and positive situation transformation relationship between the disasters nature and resources nature of water, and the relationship among water situation changes and economic, social and ecological systems, guides the integration and optimization of the existing flood control systems, drought control systems, and irrigation systems to form a new type of cost-efficient, energy-efficient, low-carbon footprint, easy-to-build and -handle water management system with significant comprehensive benefits.

The study of Suitaiology will enhance the development and utilization of water resources, accelerate the progress of combating the disasters of drought and flood and desertification, and support sustainable ecological environment, economic growth, social development and poverty eradication.

      Suitaiology overlaps with the closely related sciences of geology, geography, meteorology, pedology, physics, ecology, social economics, agronomy, forestry, water resources, hydraulic engineering. It takes sustainable development as its basic ideological principles, and applies the concepts, knowledge and research methods from systems theory, cybernetics, information theory, operations research, and circular economy, etc.

Definition:  The interactions between water and other subsystems in the large-scale WHNE system and the dynamic tendency of this interaction.  
Keynote I: Water situation varies with time, space, target and the mass or velocity of water.  
Keynote II: Excessive water or overspeed water may cause disasters, such as flood and derived geological, ecological and social disasters hazards.  
Keynote III: Drought is also a water situation but water mass tends to zero.

      The “water-human-natural environment" (WHNE) system constitutes the unique natural system of our planet.  

       This is a dynamic system that internal members restricts and promotes each other. Wind and water rise, mountains and rivers change, growth or death, etc., are all the romances within this system. Thus, “Situation”, or another better word, here is defined as a set of tendencies of developments in which one finds oneself, or a state of affairs, and is of an inclination toward a particular characteristic or type of behavior. “Situation” is displayed by the interaction between members of the system, has the target and purpose of action, and can be stimulated or restricted or changed by the action of other members of the system.  

      For the human and natural environment subsystem, the water situation varies with time, space, and target. It can be devil-like or angel-like.  

      In a certain way, water situation can be roughly digitized by the momentum of water:  

      The formula of momentum (p): p = (mass)(velocity).  

      From a digital point of view, the water situation can change with the change of flow mass or velocity, but depend upon its target and purpose. Obviously, in addition to the initial mass and velocity of the water itself, the water situation is restricted or effected, enhanced or changed by other members of the system to which it belongs.  

      Excessive water or overspeed water, whether water droplets or water flow, may cause disasters, such as flood, soil erosion, landslide, debris flow, etc. The threshold values of excess or overspeed are various depending on space, time and time period.  

      Drought is also a water situation but water mass tends to zero, and impacts on the quality or existence of life.
