Integrated Water Resource Management (IWRM) is the most emphasized topic during water related planning and infrastructural development. In IWRMnotes, it has been tried to cover different issues and topics related to IWRM and Water Resources Engineering. By this way to use it for creating awareness and spread of knowledge.

Purpose of Sediment Transport Studies
Even with progression of science and technology, sediment transport remains a phenomenon that is not fully comprehended. Numerical modeling is a common method to analyze sediment transport and subsequent bathymetric changes. This helps in gaining an insight into the prospective behavior of sediment transport, which provides a background for policy making. Among several of benefits of such studies may include estimation of possible expenditure in coming years, to take out deposited sediments and estimation of the dam life to serve its planned purposes.

Integrated Water Resource Management (IWRM) – Basic Concept
The basic idea behind the concept of IWRM is that fresh water is a scarce entity and all different uses of fresh water are all different uses of it are all competing and interdependent. And while this evident to all of us, so far not proper attention has been paid to it. Some of examples of its mutual-dependent uses are
· High demand for irrigation purposes of fresh water mean that there will less water left for Industrial and Drinking purposes
· If contaminated wastewater from municipalities and industries is allowed to be flow out into main river system unattended and untreated, it will harmful for the fisheries, ecosystem and biodiversity.
· And if the water is protected and retained for fisheries and biodiversity the less can diverted for other purposes like irrigation.
· A dam or other water retaining structure is very useful for collecting and distributing water as and when required for irrigation purposes, controls flooding and can be used for power generation. While on the other hand it increases water logging at upstream, harmful for that particular river system’s unique biodiversity. And if the water is stored in rivers, very less water is the end of river flows are almost dried up resulting saline sea water intrusion into delta land.
So examples are many and they all prove that all different water uses unregulated use of scarce water resources is extremely wasteful and unsustainable. That use may give a temporary or short term benefit for one purpose but may also produce much more danger to somewhere else.
So in IWRM, Integrated means that all different uses of water resources are to be considered together. And water allocations and management decisions should account for an overall sociological and economical goals and also include the sustainable development. And a coherent policy making related to all sectors needs to be existed. One of the way to achieve this integrated policy and decision making is to involve all user groups (e.g. farmer, household users, industrialists etc.) in water resource management from initiation of policy making till the management. And from national level to grass root level. And by this way we will get many additional benefits such as, informed users apply local self regulations related to issues such as water conservation and catchment protection far more effectively than central regulation and surveillance can achieve.
Management is used in a more broader sense, And means that we must only just to focus on day to day management of water resources. But we must consciously manage water development in a ways that ensures long terms sustainable use even for future generations. And that we must left the plant in even better state for our new generations to come so that also get benefited from its resources as we are now.
And as defined by Cap-Net “Integrated Water Resources Management is therefore a systematic process for the sustainable development, allocation and monitoring of water resources use in the context of social economic and environmental objectives.” And it further says implies that “It contrast with sectoral approach that applies in many countries.” Like where responsibility of drinking water rests with one agency, for irrigation with another and for the environment yet another, lack of cross –sectoral linkages leads to uncoordinated water resources development and management. And this is what results in disputed and unsustainable system.

European Union’s Water protection and management (Water Framework Directive)
The Water Framework Directive (more formally the Directive 2000/60/EC of the European Parliament and of the Council of 23 October 2000 establishing a framework for Community action in the field of water policy) is a European Union directive which commits European Union member states to achieve good qualitative and quantitative status of all water bodies (including near shores’ marine waters) by 2015. It is a framework in the sense that it prescribes steps to reach the common goal rather than adopting the more traditional limit value approach.
The directive defines 'surface water status' as the general expression of the status of a body of surface water, determined by the poorer of its ecological status and its chemical status. Thus, to achieve 'good surface water status' both the ecological status and the chemical status of a surface water body need to be at least 'good'. Ecological status refers to the quality of the structure and functioning of aquatic ecosystems of the surface waters. Water is an important facet of all life and the water framework directive sets standards which ensure the safe access of this resource.
The Directive requires the production of a number of key documents over six year planning cycles. Most important among these is the River Basin Management Plans, to be published in 2009, 2015 and 2021. Draft River Basin Management Plans are published for consultation at least one year prior.
Good ecological status is defined locally as being lower than a theoretical reference point of pristine conditions, i.e. in the absence of anthropogenic influence. Article 14 of the directive requires member states "to encourage the active involvement of interested parties" in the implementation of the directive. This is generally acknowledged to be an assimilation of the Aarhus Convention
ACT
Directive 2000/60/EC of the European Parliament and of the Council of 23 October 2000 establishing a framework for Community action in the field of water policy
Summary
The European Union (EC) has established a framework for the protection of:
inland surface waters *;
groundwater *;
transitional waters *; and
and coastal waters *.
This Framework-Directive has a number of objectives, such as preventing and reducing pollution, promoting sustainable water usage, environmental protection, improving aquatic ecosystems and mitigating the effects of floods and droughts.
Its ultimate objective is to achieve “good ecological and chemical status” for all Community waters by 2015.
Administrative arrangements
Member States have to identify all the river basins * lying within their national territory and to assign them to individual river basin districts *. River basins covering the territory of more than one Member State will be assigned to an international river basin district.
Member States are to designate a competent authority for the application of the rules provided for in this Framework-Directive within each river basin district.
Identification and analysis of waters
· By 2004 at the latest, each Member State shall produce:
· an analysis of the characteristics of each river basin district;
· a review of the impact of human activity on water;
· an economic analysis of water use;
· a register of areas requiring special protection;
· a survey of all bodies of water used for abstracting water for human consumption and producing more than 10 m³ per day or serving more than 50 persons.
This analysis must be revised in 2013 and every six years thereafter.
Management plans and programmes of measures
In 2009, nine years after the Framework-Directive entered into force, management plans were produced for each river basin district, taking account of the results of the analyses and studies carried out. These plans cover the period 2009-2015. They shall be revised in 2015 and then every six years thereafter.
The management plans must be implemented in 2012. They aim to:
- prevent deterioration, enhance and restore bodies of surface water, achieve good chemical and ecological status of such water by 2015 at the latest and to reduce pollution from discharges and emissions of hazardous substances;
- protect, enhance and restore the status of all bodies of groundwater, prevent the pollution and deterioration of groundwater, and ensure a balance between groundwater abstraction and replenishment;
- preserve protected areas.
The management plans for river basin districts can be complemented by more detailed management programmes and plans for a sub-basin, a sector or a particular type of water.
Temporary deterioration of bodies of water is not in breach of the requirements of this Framework-Directive if it is the result of circumstances which are exceptional or could not reasonably have been foreseen and which are due to an accident, natural causes or force majeure.
Member States shall encourage participation by all stakeholders in the implementation of this Framework-Directive, specifically with regard to the management plans for river basin districts. Projects from the management plans must be submitted to public consultation for at least 6 months.
From 2010, Member States must ensure that water pricing policies provide adequate incentives for users to use water resources efficiently and that the various economic sectors contribute to the recovery of the costs of water services, including those relating to the environment and resources.
Member States must introduce arrangements to ensure that effective, proportionate and dissuasive penalties are imposed in the event of breaches of the provisions of this Framework Directive.
A list of priority substances selected from among the ones which present a significant risk to the aquatic environment has been drawn up at European level. This list is set out in Annex X to this Framework-Directive.

IWRM Roamap's 25 Elements - A way to Improve IWRM Process
IWRM Roadmap as explained previously is a way to judge the current status of IWRM in a River Basin. Here the same points are listed again with comments as to how to make improvement against respective element.
| IWRM Element | Comments for Improvement |
| 1. River basin organization | Build capacity in new or existing River Basin Organization (RBO), mainly focusing on four dimensions of performance (that is stakeholders, internal business process, learning and growth and financing) under the NARBO (Network of Asian River Basin Organization's service. |
| 2. Stakeholder participation | Institutionalize the stakeholder participation in river basin planning and management process including but not limited to active participation of local governments, civil society organizations (like academia, active NGOs parliamentarians, media), and the private sector and an enabling framework for meaningful stakeholder participation in project specific and planning decisions. |
Definition of IWRM
As far as definition of IWRM is concerned, each active entity has defined or more precisely expressed IWRM in its own style, which in a broader sense required the same efforts to implement and yields the same result. So it would be interesting to look at how GWP (Global Water Partnership) EC (European Commission) and USAID defines the IWRM.
1. GWP definition of IWRM as “A process that promotes the co-ordinated development and management of water, land and related resources, in order to maximize the resultant economic and social welfare in an equitable manner without compromising the sustainability of vital ecosystems.”
2. And EC describes it with same meaning but with slightly different wordings “IWRM expresses the idea that water resources should be managed in a holistic way, coordinating and integrating all aspects and functions of water extraction, water control and water-related service delivery so as to bring sustainable and equitable benefit to all those, dependent on the resource (EC, 1998).”
3. And USAID expresses it as “A participatory planning and implementation process, based on sound science, that brings stakeholders together to determine how to meet society’s long-term needs for water and coastal resources while maintaining essential ecological services and economic benefits (USAID).”

A Short Overview of Current Global Water Picture
Resources are insufficient
Currently the water resources at global scale are stressed due to over exploitation. Water demands like for agriculture, industry and domestic use are increasing day by day. One of the main reason for this urbanization and population growth.
![]() |
| Trends in Global Urbanization |
Demand loads are exceeding the available supplies
Average renewable water : ca 2000 m3
Per person and year (Engelman, LeRoy, 1993)
Substantial part of which is used by ecosystems
Amount remained for human use: ca 1000 m3
1 000 000 L/person/year = 2740 L/person/day
Out of which:
69% is used for irrigation (- 1890 L/person/day)
23% is used by industry ( (- 630 L/person/day)
Only 8% remains for household use:
(i.e. 220 L/person/day)
Average household consumption in some areas in the world are as follows
USA: 700 L/p/day
Sweden: 200 L/p/day
Senegal: 29 L/p/day
Nomad in Sahara: 5 L/p/day
Severe Environmental/Ecological issues are severe
Due to the incoming pollution and unplanned water activities (e.g. unplanned damming affecting natural river flows too much) at the up streams the biodiversity is depleting slowly in Mekong , Amazon and Indus river basins and other problems like intrusion of sea water in delta ect. are resulting.
Policy and institutional issues are complicated
Harmony in water use policies for different purposes and among different stakeholders needs to be established. The situation became even more difficult to manage in situations when one river is crossing two or more international borders.
Fragmented and Sectoral Present approach
In most of the places in world, for different uses, water is managed by different departments which sometimes have entirely different and even contradicting goals. And no harmony in the policy exists.
Available choices are highly capital demanding
Water related structures are considered one of the costlier and time taking projects and with no immediate or near future results. Therefore a huge effort is required to establish the political will to invest in such projects.
