“…5, 6). The piper diagrams provide a convenient method to classify water types collected from different groundwater resources, based on the ionic composition of different water samples (Aly 2015;Semerjian 2011;Al-Omran et al 2012;Baba et al 2008). The main water types have been identified on the basis of the major ion concentrations such as in Aly and Benaabidate (2010) and Aly et al (2013).…”

“…It is under-saturated if the SI \ zero and it is over-saturated when the SI [ zero. Nonetheless, to overcome the measurement inaccuracies and changes in the water composition when it makes its way towards the surface, it is proposed to consider a wider range of SI, such as -1 \ SI \ ?1 (Aly 2015). Figure 10a, b shows the mineral saturation indices (SI) of water calculated by PHREEQC model.…”

-at slightly high concentration. The water quality index (WQI) reveals that 94% of the samples were excellent for drinking (class I). While the remaining was unsuitable due to total coliform group contamination ''class (V)''. Durov diagram suggest no clear facies and dominant water type can be noted. It indicates mixing processes of two or more different facies might be occurring in the groundwater system. All studied waters were undersaturated with respect to halite, gypsum, fluorite, and anhydrite. These minerals tend to dissolve and increase water salinity. A direct relationship between Zamzam water salinity and rainfall is recorded. The water salinity fluctuated between 4500 mg L -1 (year 1950) and 500 mg L -1 (year 2015) based on rainfall extent. The approach applied can be used to similar groundwater worldwide.

“…Major water quality problems for irrigation are salinity, sodicity and alkalinity (Simsek & Gunduz, 2007;Sadashivaiah et al, 2008;Nazzal et al, 2014). An appropriate assessment of water for irrigation requires the determination of of physical, chemical and biological parameters that are greatly influenced by geological formations and anthropogenic activities (Sarath Prasanth et al, 2012;Al-Khashman & Jaradat, 2014;Al-Harbi et al, 2014) and directly related to the classifying of water quality (Saber et al, 2014;Aly, 2014;Aly et al, 2014). Several quality indices can be used to assess the suitability of water for irrigation; the most commonly used are salinity hazards, percent sodium (% Na), sodium adsorption ratio (SAR), residual sodium carbonate (RSC), soluble sodium percentage (SSP), residual sodium bicarbonate RSBC), permeability index (PI), potential salinity (PS), Kelley's index (KI) and magnesium hazard (MH) (Tatawat & Chandel, 2008;Sarath Prasanth et al, 2012;Al-Harbi et al, 2014;Nag, 2014).…”

The research was conducted to assess the aflaj water quality in Al Jabal Al Akhdar, Oman. 9 aflaj were sampled during summer and winter seasons in 2012-2013 to evaluate for the physico-chemical characteristics of major quality parameters; and assess the suitability of aflaj for irrigation purposes. Samples collection, handling and processing followed the standard methods recommended by the American Public Health Association and analysed in quality assured laboratories using appropriate analytical methods and instrumental techniques. The quality parameters of the selected aflaj water indicated their suitability for irrigation as most of the quality parameters were within the permissible limits set by Omani regulations of wastewater reuse for irrigation. These selected water resources are excellent or good in quality for irrigation purposes based on the evaluation of different hazards parameters including the salinity-alkalinity hazards which indicate good to admissible water based on electrical conductivity and sodium adsorption classification; and water quality indices which reveal high or moderate classes, indicating the suitability of aflaj for irrigation of the majority of crops and soils. This study is a first comprehensive assessment towards providing indicators and classification indices on irrigation water quality of this fragile mountain ecosystem, which will be the basis for future planning decisions on agricultural demand management measures to protect these principal resources for agricultural production in Al Jabal Al Akhdar.

“…Soil piping is a natural process, but it can become a disaster or trigger any other disasters like land slide, debris flow and slope failure (Ajaykumar et al 2011). Piping has been observed in both natural and anthropogenic landscapes, in a wide range of climatological, geomorphological and pedological settings (Bryan and Jones 1997;Faulkner 2006;Aly 2014). Piping may also occur on hillside slopes, on the crowns and sides of miniature bad land mountain and in bad land ravine or gully channels or channel walls (Parker 1963).…”

Evaluation of the factors controlling the spatial distribution of soil piping: a case study from the southern Western Ghats, India

et al. 2015

Soil piping (tunnel erosion) is a soil-related natural disaster. It is a type of sub-surface erosion, which involves the hydraulic removal of sub-surface soil causing the formation of an underground passage in landscape. Soil piping significantly affects the most responsive run-off systems of the humid tropics. Southern parts of the Western Ghats have recorded seven incidents of this phenomenon within a period of 1 year, starting from August 2010 to August 2011. Out of the seven incidents recorded from the Ghats regions falling in Idukki District of Kerala, south India, the main aspects and parameters of four locations were evaluated and correlated by synthesizing the physical, chemical, geological and hydrological parameters. The evaluation showed a similar expression of physical, chemical and hydrological components of soil at the sites 1, 2 and 4, which does not normally favour the phenomena of soil piping, while site 3 has chemical components favouring its development. Even though the pipe outlets were observed at or near the foothills, the mechanism behind the recharging is to be clarified further more. The study reveals that the phenomenon has been recorded from a variety of geographical entities with no common contributing system, except the intensity of rainfall and vicinity to prominent structural controls. Hence, the increased periodicity of occurrence of the incidents is attributed to the stress-induced dilatation of the sub-surface water-bearing formations before and after a series of mild tremors recorded contemporaneously from Idukki District, Kerala.
