“…Mexico faces a serious infelicity in that much of its population (in the Northeast, for instance) is clustered in areas that have little in the way of indigenous water (National Water Commission, 2015). And other evidence from the past few years plainly reveals a steady decline in the water infrastructure of Mexico since the dawn of the 2000s (Castilla-Hernández et al , 2014). Thus, what becomes manifest is that poor managerial practices have been married to declining physical infrastructures for some time, thus aggravating the existing condition to an extent that can only be viewed with alarm (Aguilar-Barajas et al , 2015).…”

Purpose The purpose of this paper is to analyse the measures taken by both the federal government of Mexico and its municipalities in relation to the country’s urban water supply and its management to improve it. Design/methodology/approach The PRISMA guidelines were chosen as the framework for this systematic review of the available literature on urban water supply in Mexico, considering the most important and relevant legal and institutional considerations. They were paired with critical qualitative review. Overall, 21 main documents, between 2000 and 2016, were acceptable for inclusion. Findings The review closes by proposing that the approach, at present, is excessively rigid, and that greater flexibility would permit municipalities to identify more suitable means of managing their own water supplies with minimal support from the federal government. Originality/value Several research articles have been written about the general nature of Mexico’s urban water supply and management at present. However, no attempt has been made to synthesise the evidence and arguments made in this significant body of research. Thus, the key purpose of this review is to do that with the intention of proposing a shift in the country’s approach to urban water management.

“…Drinking water quality index (DWQI) presents a single number to reveal the overall water quality at a particular position and time, based on various water quality factors. It is interpreted as a number that indicates the combined impact of several water quality parameters [ 19 , 24 , 25 , 26 , 27 , 28 ]. DWQI has been popularly utilized in water quality evaluations for both surface and sub-surface water, and it has represented an increasingly significant function in the water resource environment and management [ 29 , 30 , 31 ].…”

The observation of groundwater quality elements is essential for understanding the classification and distribution of drinking water. Geographic Information System (GIS) and remote sensing (RS), are intensive tools for the performance and analysis of spatial datum associated with groundwater sources control. In this study, groundwater quality parameters were observed in three different aquifers including: sandstone, alluvium and basalt. These aquifers are the primary source of national drinking water and partly for agricultural activity in El Faw, El Raha (Fw-Rh), El Qalabat and El Quresha (Qa-Qu) localities in the southern part of Gedaref State in eastern Sudan. The aquifers have been overworked intensively as the main source of indigenous water supply in the study area. The interpolation methods were used to demonstrate the facies pattern and Drinking Water Quality Index (DWQI) of the groundwater in the research area. The GIS interpolation tool was used to obtain the spatial distribution of groundwater quality parameters and DWQI in the area. Forty samples were assembled and investigated for the analysis of major cations and anions. The groundwater in this research is controlled by sodium and bicarbonate ions that defined the composition of the water type to be Na HCO3. However, from the plots of piper diagram; the samples result revealed (40%) Na-Mg-HCO3 and (35%) Na-HCO3 water types. The outcome of the analysis reveals that several groundwater samples have been found to be suitable for drinking purposes in Fa-Rh and Qa-Qu areas.

“…Density currents are divided into sediment density currents, salinity density currents, and temperature density currents [25]. Sediment density currents and temperature density currents are common in source water reservoirs, with the former carrying serious exogenous pollution [26,27].…”

Extreme weather has recently become frequent. Heavy rainfall forms storm runoff, which is usually very turbid and contains a high concentration of organic matter, therefore affecting water quality when it enters reservoirs. The large canyon-shaped Heihe Reservoir is the most important raw water source for the city of Xi'an. During the flood season, storm runoff flows into the reservoir as a density current. We determined the relationship among inflow peak discharge (Q), suspended sediment concentration, inflow water temperature, and undercurrent water density. The relationships between (Q) and inflow suspended sediment concentration (C S0 ) could be described by the equation C S0 = 0.3899 × e 0.0025Q , that between C S0 and suspended sediment concentration at the entrance of the main reservoir area S1 (C S1 ) was determined using C S1 = 0.0346 × e 0.2335CS0 , and air temperature (T a ) and inflow water temperature (T w ) based on the meteorological data were related as follows: T w = 0.7718 × T a + 1.0979. Then, we calculated the density of the undercurrent layer. Compared to the vertical water density distribution at S1 before rainfall, the undercurrent elevation was determined based on the principle of equivalent density inflow. Based on our results, we proposed schemes for optimizing water intake selection and flood discharge during the flood season.
