Lexicographic optimisation for water resources planning: the case of Lake Verbano, Italy

  
In Proceedings of the iEMSs First Biennial Meeting: Integrated Assessment and Decision Support (2002), pp. 235-240

Abstract

Lake Verbano is a natural lake used as multipurpose reservoir. The lake supplies water for irrigation and hydropower generation to downstream users, while flood controls are applied to protect the lake shores and the downstream populations on the Ticino river, and environmental preservation constraints must be respected. All these objectives are conflicting and they have different priorities, as stated by the Italian regulation on water use. This paper explores a methodology aimed at solving this conflict. The stakeholders involvement in the ...

 

Is robustness really robust? How different definitions of robustness impact decision-making under climate change

  
Climatic Change, Vol. 135, No. 3-4. (2016), pp. 409-424, https://doi.org/10.1007/s10584-015-1586-9

Abstract

Robust decision-making is being increasingly used to support environmental resources decisions and policy analysis under changing climate and society. In this context, a robust decision is a decision that is as much as possible insensitive to a large degree of uncertainty and ensures certain performance across multiple plausible futures. Yet, the concept of robustness is neither unique nor static. Multiple robustness metrics, such as maximin, optimism-pessimism, max regret, have been proposed in the literature, reflecting diverse optimistic/pessimistic attitudes by the decision ...

 

The SmartH2O project and the role of social computing in promoting efficient residential water use: a first analysis

  
In Proceedings of the 7th International Congress on Environmental Modelling and Software, June 15-19, San Diego, California, USA (2014)

Abstract

SmartH2O is an EU funded project which aims at creating a virtuous feedback cycle between water users and the utilities, providing users information on their consumption in quasi real time, and thus enabling water utilities to plan and implement strategies to reduce/reallocate water consumption. Traditional metering data, usually gathered twice a year, can be used to model consumers’ behaviour at an aggregate level, but the motivations and individual attitudes of consumers are hidden. The advent of smart water meters allows gathering high frequency consumption data that ...

 

Putting humans in the loop: Social computing for Water Resources Management

  
Environmental Modelling & Software, Vol. 37 (November 2012), pp. 68-77, https://doi.org/10.1016/j.envsoft.2012.03.002

Abstract

The advent of online services, social networks, crowdsourcing, and serious Web games has promoted the emergence of a novel computation paradigm, where complex tasks are solved by exploiting the capacity of human beings and computer platforms in an integrated way. Water Resources Management systems can take advantage of human and social computation in several ways: collecting and validating data, complementing the analytic knowledge embodied in models with tacit knowledge from individuals and communities, using human sensors to monitor the variation of ...

 

A procedural approach to strengthening integration and participation in water resource planning

  
Environmental Modelling & Software, Vol. 21, No. 10. (October 2006), pp. 1455-1470, https://doi.org/10.1016/j.envsoft.2005.07.013

Abstract

Integrated Water Resources Management (IWRM) is emerging as a worldwide agreed alternative to the reductionist and top-down approach that was central to the water resource management in the last century. It has been adopted by the Water Framework Directive, the most ambitious and influential water policy tool of these days, as the guiding principle for the development of River Basin Management Plans (RBMP) that will be the common tool for planning and managing water resource in Europe in the next years. ...

 

IWRM in the Adda basin, Northern Italy

  
Geophysical Research Abstracts In European Geosciences Union (EGU) General Assembly 2013, Vol. 9 (2007), 08901

Abstract

The Adda river basin, in Northern Italy, is a 6.500 km2 wide basin which includes the Como Lake. The lake has been used as a regulated multipurpose reservoir for sixty years and its management has been primarily aimed at the satisfaction of downstream water demands for irrigation and hydropower generation, as well as at the control of floods, both on the lake shores and on the outflowing Adda river. Due to the changing legal and hydrological conditions the conflict between these ...

 

A participatory and integrated planning procedure for decision making in water resource systems

  
In Topics on System Analysis and Integrated Water Resources Management (2007), pp. 3-23, https://doi.org/10.1016/b978-008044967-8/50001-4

Abstract

This chapter presents a participatory and integrated planning procedure for decision making in water resource systems. In many parts of the world, water demand is increasing, while at the same time, availability and quality of water resources are decreasing, mainly due to human activities, in connection with the growing world population, ongoing urbanization, industrialization, and the intensification of agriculture. This development is often associated with general reductions in environmental quality and endangers sustainable development. An integrated approach is required to identify ...

 

PIP: a Participatory and Integrated Planning procedure for decision making in water resource systems

  
In Modelling and control for participatory planning and managing water systems (September 2004)

Abstract

There is a wide consensus that integrated planning and management (iwrm) plays a crucial role in the current context of water resources, as well as that any water related decisional process must be participated in order to reach transparent and readily acceptable decisions. At European level the iwrm paradigm has been adopted by the Water Framework Directive that came into force in December 2000. The directive sets out a detailed framework for the improved planning and management of water, including in ...

 

On-line design of water reservoir policies based on inflow prediction

  
IFAC-PapersOnLine In Proceedings of the 17th IFAC World Congress, Vol. 41, No. 2. (06 July 2008), pp. 14540-14545, https://doi.org/10.3182/20080706-5-kr-1001.02463

Abstract

Stochastic Dynamic Programming (SDP) is the method most extensively adopted to design release policies for water reservoir networks. However, it suffers of the well known "curse of dimensionality", which actually limits its applicability to small reservoir networks. In this paper we present an on-line approach to policy design that not only constitutes a viable alternative to overcome the SDP limits, but can also be used with an inflow predictor to improve the performance of SDPbased off-line policies. This latter possibility is ...

 

Choosing among infinite alternatives

  
In Integrated and participatory water resources management theory (2007), pp. 223-242

Abstract

In Chapter 7 we understood that, even when the Decision Maker (DM) is acting in conditions of full rationality, the design of the alternatives poses three difficulties: the presence of infinite alternatives; the presence of uncertainty produced by random disturbances; and the presence of recursive decisions. In this chapter, we begin to describe the tools to overcome these difficulties by analysing the Design Problem in the simplest of cases: the case in which the actions being considered are all planning actions ...

 

Integrated and participatory water resources management - Theory

  
(2007)

Abstract

Covering the more recent advances in Modelling, Planning, Management and Negotiations for Integrated Water Resource Management, this text brings together knowledge and concepts from Hydrology, System Analysis, Control Theory, Conflict Resolution, and Decision and Negotiation Theory. Without compromising on mathematical rigour, the book maintains a fine line between theory and application, methodology and tools, avoiding getting locked into excessively theoretical and formal development of the issues discussed. The non-technical aspects of water resource systems (such as societal, political and legal concerns) ...

 

Neuro-dynamic programming for designing water reservoir network management policies

  
Control Engineering Practice, Vol. 15, No. 8. (August 2007), pp. 1031-1038, https://doi.org/10.1016/j.conengprac.2006.02.011

Abstract

Stochastic dynamic programming (SDP) can improve the management of a multipurpose water reservoir by generating management policies which are efficient with respect to the management objectives (flood protection, water supply for irrigation, hydropower generation, etc.). The improvement in efficiency is even more remarkable for networks of reservoirs. Unfortunately, SDP is affected by the well-known ‘curse of dimensionality’, i.e. computational time and computer memory occupation increase exponentially with the dimension of the problem (number of reservoirs), and the problem rapidly becomes intractable. ...

 

Participatory decision making in reservoir planning

  
In 1st biennial meeting of the IEMSS (2002), pp. 34-44

Abstract

The technologies and methods for integrated planning and management of water resource systems have matured considerably over the past decades. However, relatively few of them have been actually and regularly applied in real world decisional processes. We feel this is essentially due to a general lack of engagement of stakeholders and decision makers at every stage of the decisional process. Innovative methodologies and tools to improve participation are presented, with focus on water reservoir systems. ...

Neuro-Dynamic Programming for the efficient integrated water resources management

  
In Modelling and control for participatory planning and managing water systems (30 September 2004)

Abstract

Design of policies within the integrated water resources management (IWRM) paradigm demands to take into account multiple objectives such as flood protection, water supply for hydropower generation, irrigation and urban use, imposition of minimum environmental flows, etc.. Finding efficient water management policies is a demanding task and Stochastic Dynamic Programming (SDP) can provide an effective solution methodology. The efficiency boost is even more pronounced when the scale of integration of the water management problem spans networks of water resources (i.e. sets of interconnected reservoirs, or wide-area ...

Abstract

An approach to the integrated water resources management based on Neuro-Dynamic Programming (NDP) with an improved technique for fastening its Artificial Neural Network (ANN) training phase will be presented. When dealing with networks of water resources, Stochastic Dynamic Programming provides an effective solution methodology but suffers from the so-called "curse of dimensionality", that rapidly leads to the problem intractability. NDP can sensibly mitigate this drawback by approximating the solution with ANNs. However in the real world applications NDP shows to be ...
