“…For example, the application of artificial neural networks (ANNs) has been used to evaluate the hydrological consequences of climatic situations in terms of the probability of demand failure in a water resources system in the Guadalquivir River Basin, southern Spain [42]. ANNs have also been used to identify maps of the probabilities of drought occurrences in Portugal [43], while a multi-objective optimization model has been applied for rural water supply systems in Cuiabá, Brazil [44]. In other studies, the envision rating system was used to assess the sustainability of groundwater infrastructure to address concerns for water supply [45].…”

Abstract:The Hexi Corridor, an important part of the Silk Road Economic Belt, is considered the poorest, most water scarce, and most ecologically fragile area in China. Establishing efficient strategies for water management in an integrated manner is utterly important. This paper evaluates the spatio-temporal trends of water stress (2003)(2004)(2005)(2006)(2007)(2008)(2009)(2010)(2011)(2012)(2013)(2014)(2015) in the Shule (SLRB), Heihe (HHRB), and Shiyang (SYRB) River Basins in the Hexi Corridor based on the Water Poverty Index (WPI). For SLRB, the WPI ranged from 55.3 to 66.4, followed by HHRB (40.1-58.2) and SYRB with WPI = 20.0-43.9. Both SYRB and HHRB showed an improvement in the water situation based on increasing trends, whereas SLRB demonstrated a small decrease. The effectiveness of water policy interventions was evident in SYRB and HHRB, standing at odds with SLRB where interventions required adjustment to ameliorate the water stress. For the start and end years, pentagrams for five components (Resource, Access, Capacity, Use, Environment) demonstrated the merits and weaknesses of WPI as a comparative framework for assessing the water situation. This study also reaffirms the importance of WPI, utilized for investigating the efficacy of implemented water policies and benchmarking the future priorities in basins not only in China but also in other locations where water resources management is a key issue.

Abstract This study aimed to present a methodology for locating water distribution reservoirs in rural Andean areas (isolated areas, low-income population, mountainous region). The research methodology consisted of the following steps: (1) description of the problem; (2) development of the DR location protocol; (3) obtaining an algorithm; (4) calibration and adjustment; and (5) application. The obtained algorithm was based on the classification and overlapping operations of five-parameter maps (pressure limits – pressure in the water supply system from 5 to 40 mH2O; supply by gravity – guarantee of gravity as energy for water movement; accessibility – use of unprotected areas or with restricted occupation; stability, greater distance from geological fault; and, proximity to population concentration, shorter distance between population centres). The overlapping of these parameters enabled us to identify a region of candidate points and select the best location point for the reservoir. The algorithm was applied to a real case indicating satisfactory results. A methodology for locating water distribution reservoirs in rural areas that have important economic constraints, difficult access (mountainous region) and high geospatial dispersion was found. Improvements in methodological steps can still be considered, for example, forecasting the use of pressure control devices in the water supply system.
