This document discusses progress on river health assessment and environmental flows allocation in China. It outlines several pilot projects from the 1990s that improved river health. It also describes China's National River Health Assessment Programme, which aims to establish a river health assessment system. The programme involves pilot assessments of selected rivers and lakes and research on indicators, standards, and methodologies. Challenges include a lack of knowledge and data as well as difficulties with interagency collaboration and implementation of environmental flows requirements. The document advocates continuing bilateral cooperation between China and Australia to address these challenges.
Presented by Vladimir Smakhtin at the Ministry of Water Resources, New Delhi, India, November 4, 2014.
The flows of India’s rivers are increasingly being modified by dams and weirs and abstractions for agriculture and urban use. These interventions have caused significant alteration of flow regimes mainly by reducing total flow and affecting its variability and seasonality. An Environmental Flow (EF) is the water regime provided within a river, wetland or coastal zone to maintain ecosystems and their benefits. Environmental Flows describe the quantity, quality and timing of water flows required to sustain freshwater and estuarine ecosystems and the human livelihoods and well-being that depend on these ecosystems. This presentation looks at how the EF approach has been tested in India and describes a project to apply EF methodology to the upper Ganga.
This presentation was given at the 2019 Catchment Management Notwork meeting, which was held on the 11 October in Tullamore. All our local authorities and other bodies responsible for implementing the Water Framework Directive in Ireland attended to share knowledge and learn from each other.

Lake Water Quality Indexing To Identify Suitable Sites For Household Utility:...IJERA Editor
Water management practices need a fresh look in order to avoid water crisis in the next two decades. This
essentially requires looking for proper management practices for growing economy and population. The water
resources of the Lake basins remain almost constant while demand of water for various purposes is increasing.
Water pollution as a corollary of accelerated industrial growth has drawn concerns over public health and
environment. Water is required for different purposes like domestic, agricultural, hydro-power, navigation,
recreation, etc. Utilization in all these diverse uses of water should be optimized and an awareness of water as a
inadequate resource should be fostered. Water quality index (WQI) is precious and unique rating to depict the
overall water quality status in appropriate treatment technique to meet the concerned issues. This paper
elaborates on the WQI concepts and current scenario of Jambhulwadi Lake which will help in future as natural
potable groundwater resource. It also focuses on case scenario of calculating WQI using Weighted Arithmetic
Water Quality Index an example dataset. The quality of water way to evaluate by testing various physicochemical
parameters such as pH, Temperature, Total Dissolved Solid (TDS),Alkalinity Total Hardness,
Dissolved Oxygen (DO), Biological Oxygen Demand (BOD),Chemical Oxygen Demand (COD), Nitrites,
Phosphate, Conductivity

Evaluation of Potential Physico-Chemical Ground Water Pollution: a Case Study...EditorIJAERD
Ground water is a large source of water for utilisation in the world. This resource is not easily accessible to
monitor its changes and its deterioration is not easy to reverse. In the current study, physico-chemical parameters of
groundwater for Kiwanja Market (KM) were analysed and compared to the Kenya Bureau of Standards (KEBs) water
quality. The pH, DO, temperature, turbidity, chlorine, iron, water hardness, potassium and calcium were analysed. All the
parameters studied were within the stipulated levels except iron, and chloride for samples from point C (Ebenezer Hostel).
Turbidity for samples from points A and C were above the permissible levels of KEBs standards. The water sampled from
point A and C may require further treatment to allow for domestic use. This analysis revealed to some extent a healthier
system, though further analysis is needed to support this assertion. Continuous monitoring of the groundwater sources
within KM should be taken on regular basis to detect any changes and to sustainably maintain the quality of water within
the required KEBs water quality standards.

Epistemic Interaction - tuning interfaces to provide information for AI supportAlan Dix
Paper presented at SYNERGY workshop at AVI 2024, Genoa, Italy. 3rd June 2024
https://alandix.com/academic/papers/synergy2024-epistemic/
As machine learning integrates deeper into human-computer interactions, the concept of epistemic interaction emerges, aiming to refine these interactions to enhance system adaptability. This approach encourages minor, intentional adjustments in user behaviour to enrich the data available for system learning. This paper introduces epistemic interaction within the context of human-system communication, illustrating how deliberate interaction design can improve system understanding and adaptation. Through concrete examples, we demonstrate the potential of epistemic interaction to significantly advance human-computer interaction by leveraging intuitive human communication strategies to inform system design and functionality, offering a novel pathway for enriching user-system engagements.

Effective Application Security in Software Delivery lifecycle using Deployment Firewall and DBOM
The modern software delivery process (or the CI/CD process) includes many tools, distributed teams, open-source code, and cloud platforms. Constant focus on speed to release software to market, along with the traditional slow and manual security checks has caused gaps in continuous security as an important piece in the software supply chain. Today organizations feel more susceptible to external and internal cyber threats due to the vast attack surface in their applications supply chain and the lack of end-to-end governance and risk management.
The software team must secure its software delivery process to avoid vulnerability and security breaches. This needs to be achieved with existing tool chains and without extensive rework of the delivery processes. This talk will present strategies and techniques for providing visibility into the true risk of the existing vulnerabilities, preventing the introduction of security issues in the software, resolving vulnerabilities in production environments quickly, and capturing the deployment bill of materials (DBOM).

Elevating Tactical DDD Patterns Through Object CalisthenicsDorra BARTAGUIZ
After immersing yourself in the blue book and its red counterpart, attending DDD-focused conferences, and applying tactical patterns, you're left with a crucial question: How do I ensure my design is effective? Tactical patterns within Domain-Driven Design (DDD) serve as guiding principles for creating clear and manageable domain models. However, achieving success with these patterns requires additional guidance. Interestingly, we've observed that a set of constraints initially designed for training purposes remarkably aligns with effective pattern implementation, offering a more ‘mechanical’ approach. Let's explore together how Object Calisthenics can elevate the design of your tactical DDD patterns, offering concrete help for those venturing into DDD for the first time!

Progress of river health and e flow in china
1. Progress of River Health
Assessment and Environmental
Flows Allocation in China
Dr . Yu Xingjun
Ministry of Water Resources of China
February 2011
2. Background
Many rivers and lakes suffer quality deterioration,
changes in morphology and hydrology, as well as
habitat degradation.
Since 1990s, water reallocations have been carried
out in the Yellow River, Hei River and Tarim River, which
reduced deterioration of river health in those basins.
3. Background
In 1990s, a number of projects have been implemented which
have improved river health, including:
“Water Supply to Zhalong Wetland”
“Water Diversion from the Yangtze River to the Taihu Lake”
“Water Supply to the Nansihu Lakes”
“Water Diversion from the Yellow River to the Baiyangdian
Lake”
“Reservoirs Dispatching for Pollution Dilution in the Huai
River ”
“Water Regulation to Control Sea Water Intrusion in the
Estuary of the Pearl River”
Starting in 2004, pilot projects have been undertaken in 12
cities to carry out ecological protection and rehabilitation of the
rivers and lakes in these regions.
4. National River Health Assessment Programme
(NRHAP)
Purpose: To help MWR and seven major river basin commissions
perform their role in water and ecological protection and contribute to
the achievement of river health objectives by 2020.
Outputs:
(i) river health assessment system established at national and major
river basin levels;
(ii) river health assessment bulletin issued to the public every 2 to 3
years .

indicators, standards and methodologies
Data base: Inadequate data and capacity on biological
and habitats monitoring
Interagency collaboration: pollution (environmental
protection), wetland (forestry), fishery (agriculture)
Lack of empirical studies: limited cases available in
terms of number and types
9. Environmental Flows
The 2002 Water Law requires that ecological water
demand to be taken into consideration while developing and
allocating water resources
One of the key principles guiding the preparation of the
national Integrated Water Resources Plan (IWRP) 2009 is to
balance the water demands for domestic, productive and
ecological use, and meet the basic water needs of rivers and
lakes.
IWRP 2009 proposes an objectives of national e-flows by
2030 in terms of total volume
10. Challenges
associated
with
E-‐flows
• Although objectives are set in IWRP 2009, e-flows have
generally not been allocated to individual rivers/lakes
• E-flows analysis is qualitative and only a total (average
annual) volume is prescribed – e-flows are not defined
with reference to the required timing of the flow.
• Great difficulties exist while taking e-flows requirements
into water resources administration, especially due to
over-allocation and high demands for water

Field works, training and workshops have improved the
capacity building of Chinese organisations involved. Impacts
have been observed beyond the scope of RHEFC.
12. Next Steps for Bilateral Cooperation
Extension proposal of RHEFC was approved by ACEFP on
Feb. 22, 2011.
Extension will reinforce the approached already promoted
during the current project
Extension will help MWR test national river health guidelines,
including identification of indicators and formulation of
standards
13. Next Steps for Bilateral Cooperation
Extension will provide advice and policy recommendations
on e-flows, water allocation and basin planning methods based
on international reviews.
Extension will further strengthen capacity building of Chinese
sides through training, workshops, publication and
dissemination.
14. Next Steps for Bilateral Cooperation
MWR and Queensland Department of Environment and Resource
Management are preparing a MOU. International Economic and
Technical Cooperation and Exchange Centre and International Water
Centre will be responsible for implementation.
The purpose of this MOU is:
(i) to continue previous collaborations
(ii) to facilitate the long-term sharing of knowledge and expertise
in relation to the sustainable management of water resources
(iii) to collaborate across areas of education and training, applied
research, and targeted project design and implementation
River health and e-flows are identified as two of the priority topics.
