Summary
This study introduces an Optimum Integrated Water Resources Management (OP-IWRM) approach to tackle complex, large-scale water management challenges. The novel method successfully improved economic, social, and environmental objectives in the Diyala river basin.
Area of Science:
- Environmental science
- Water resource management
- Optimization algorithms
Background:
- Implementing holistic Integrated Water Resources Management (IWRM) models is challenging due to complexity and high-dimensional optimization problems.
- Decision-makers often downscale these problems, potentially limiting comprehensive solutions.
Purpose of the Study:
- To develop a comprehensive Optimum Integrated Water Resources Management (OP-IWRM) approach using a many-objective optimization algorithm.
- To address complex, large-scale water resource management problems effectively.
Main Methods:
- Utilized a many-objective optimization algorithm to solve complex, large-scale problems.
- Integrated social, economic, and environmental objectives, considering ground and surface water, and water infrastructure.
- Applied the OP-IWRM approach to the Diyala river basin in Iraq, incorporating seventeen objectives and over 1500 decision variables.
Main Results:
- Demonstrated comprehensive improvements across all considered targets, including revenues, community welfare, and investment policy.
- Successfully managed seventeen objectives and over 1500 decision variables in a large-scale river basin.
Conclusions:
- The OP-IWRM approach offers a viable solution for complex, large-scale water resource management, potentially enabling reconsideration of holistic IWRM implementation.
- The OP-IWRM framework can be extended to a country-scale for national sustainable development planning.

02:12Short-distance Transport of Resources
17.6K
Short-distance transport refers to transport that occurs over a distance of just 2-3 cells, crossing the plasma membrane in the process. Small uncharged molecules, such as oxygen, carbon dioxide, and water, can diffuse across the plasma membrane on their own. In contrast, ions and larger molecules require the assistance of transport proteins due to their charge or size. Transport across membranes also occurs within individual cells, playing a variety of essential roles for the plant as a whole.

01:23States of Water
56.6K
Water exists in any one of the three classical states: solid (ice), liquid (water), and gas (steam or water vapor). The state of water depends on i) the intermolecular forces that draw molecules together and ii) the kinetic energy that leads to movements that pull them apart.
Water freezes when the intermolecular forces are greater than the kinetic energy. Unlike most other substances, water is less dense in its solid state than in its liquid state. This is because each water molecule can form...

02:03Xylem and Transpiration-driven Transport of Resources
26.5K
The xylem of vascular plants distributes water and dissolved minerals that are taken up by the roots to the rest of the plant. The cells that transport xylem sap are dead upon maturity, and the movement of xylem sap is a passive process.

02:34Water and Mineral Acquisition
35.5K
Specialized tissues in plant roots have evolved to capture water, minerals, and some ions from the soil. Roots exhibit a variety of branching patterns that facilitate this process. The outermost root cells have specialized structures called root hairs that increase the root surface, thus increasing soil contact. Water can passively cross into roots, as the concentration of water in the soil is higher than that of the root tissue. Minerals, in contrast, are actively transported into root cells.

01:19Quality of Water
517
In concrete preparation, the quality of water is paramount as it affects the strength and durability of the concrete. Potable water is usually preferred; however, it must not have excessive sodium or potassium to prevent compromising the concrete's integrity. Water quality is typically evaluated based on impurities such as dissolved solids, chlorides, and sulfates, and its pH value is ideally between 6 and 8. Even slightly acidic natural water may be acceptable unless it contains harmful...

The Earth’s hydrosphere includes all of the areas where the storage and movement of water occurs. Since water is the basis of all living processes, the cycling of water is extremely important to ecosystem dynamics.
