“…Geomatics and GIS tools have been developed for the assessment of water demands and supply alternatives, as well as for the analysis of pipe and canal distribution networks. For example, WaterGEMS™ and WaterCAD™ (https://www.bentley.com/en/products/product-line/hydraulicsand-hydrology-software/watergems and https://www.bentley.com/en/products/product-line/hydraulicsand-hydrology-software/watercad) respectively use GIS and CAD systems as platforms to model and forecast water supply and demand and manage water distribution systems (Prins and Bodeaux, 2000;Wu, Z., Wang, R., Diaz, D., and Walski, 2003). Models such as the CropWat model from the United Nations Food and Agricultural Organization (http://www.fao.org/nr/water/infores_databases_cropwat.html) are integrated with GIS databases to estimate water demands based on soil types, climatological data, land use maps and expected crop areas (Al-Najar, 2011;Feng et al, 2007).…”

ABSTRACT:The availability of water-related data and information across different geographical and jurisdictional scales is of critical importance for the conservation and management of water resources in the 21 st century. Today information assets are often found fragmented across multiple agencies that use incompatible data formats and procedures for data collection, storage, maintenance, analysis, and distribution. The growing adoption of Web mapping systems in the water domain is reducing the gap between data availability and its practical use and accessibility. Nevertheless, more attention must be given to the design and development of these systems to achieve high levels of interoperability and usability while fulfilling different end user informational needs. This paper first presents a brief overview of technologies used in the water domain, and then presents three examples of Web mapping architectures based on free and open source software (FOSS) and the use of open specifications (OS) that address different users' needs for data sharing, visualization, manipulation, scenario simulations, and map production. The purpose of the paper is to illustrate how the latest developments in OS for geospatial and water-related data collection, storage, and sharing, combined with the use of mature FOSS projects facilitate the creation of sophisticated interoperable Web-based information systems in the water domain.

The losses in the urban water supply networks have become a growing concern. There are several alternatives for the quantification, detection and monitoring of water losses. However, in general, water companies have budgetary and other constraints that hinder implementation. Therefore, this paper presents a model to aid the selection of a subset of preventive maintenance actions to control water losses while accounting for the water companies' restrictions. The model combines an additive multi-attribute value analysis by applying the SMARTER method to evaluate alternatives with Integer Linear Programming (ILP). The model shows to be efficient in order to achieve a portfolio of preventive maintenance actions, particularly when the decision maker considers that, there is a compensation for attribute evaluations.
