“…This method effectively presents a runoff to reflect the changes in land use. The CN is capable of reversing the influence on alterations in land use based on runoff [20,37], and its range from 1 to 100; low values from CN indicate the low runoff [2,18,31,38].…”

“…These adverse conditions are further exacerbated by an unsustainable usage of water, such as in overexploitation. Overexploitation causes groundwater levels and water quality to decline [2]. Nevertheless, not only groundwater and surface-water hydrology are affected, but the alteration of the soil properties has led among others to deforestation and soil erosion [3].…”

“…Watershed planning is the main technique which leads to a catchment zone improvement based on the topography of the area, which can then be used throughout the year for different purposes. It is a method to store and reduce the leakage into the soil by constructing maintenance structures [2]. Four steps are required for sustainable rainwater harvesting including the choice of a set of suitable criteria, assessment of the appropriateness of the classification of each criterion, and selection of the sites and creation of suitability maps for the selected sites envisaged for water harvesting [11].Remote sensing and geographical information system (GIS) techniques have conveyed much care to identify an appropriate site for water harvesting.…”

The Middle East is an inherently dry zone. It has experienced severe drought for the last seven years, and climate change has made the situation worse. The Dohuk governorate has been suffering from an appalling water crisis. One possible way of relieving this water crisis is by properly harvesting the rainwater. Rainwater harvesting is a widely used method of storing rainwater in the countries presenting with drought characteristics. Several pieces of research have derived and developed different criteria and techniques to select suitable sites for harvesting rainwater. The main aim of this research was to identify and select suitable sites for the potential erection of dams, as well as to derive a model builder in ArcMap 10.4.1. The model combined several parameters, such as slope, runoff potential, land cover/use, stream order, soil quality, and hydrology to determine the suitability of the site for harvesting rainwater. To compute the land use/cover categories, the study depended on Landsat image data from 2018. Supervised classification was applied using the ENVI 5 software, while the slope mapping and drainage order were extracted using a digital elevation model. Inverse distance weighting (IDW) was used for the spatial interpolation of the rain data. The results demonstrated that suitable areas for water harvesting, are located in the middle and northern part of the research area, and in intensively cultivated zones. The main soil texture in these suitable sites was loam, while the rainfall rate amounted to 750 to 900 mm. This research shows that 15% and 13% of the area studied can be categorized as having excellent and good suitability for water harvesting, respectively. Furthermore, 21% and 27% of the area studied were of moderate and poor suitability, while the remaining 24% were not suitable at all.

“…Spline interpolation method was used in the present study that estimates values at unknown location (Samanta et al 2012). Kumar and Jhariya (2016) and Sayl et al (2016) have used Geographic Information System (GIS) based remote sensing approach to estimate the physical variables of rainwater harvesting. Thus, in the present study TDS and pH characteristics at 22 sample location were interpolated based on their PRM and POM observations.…”

Rainwater harvesting for drinking purpose has been a great source for survival by many societies since ages and now scarcity in water resources has been forcing many others to follow. Even though, rainwater harvesting is an exploitative practice where there is abundance of rainfall, but the methods in which harvesting process are carried needs to be studied in detail. The present study was a systematic physiochemical analysis of harvested rainwater for drinking purpose in Port Vila, Vanuatu where 22 sites were studied for two consecutive seasons. Notable mean variations were observed in total dissolved solids (TDS) with 63.84 mg/L, pH 0.4 and electrical conductivity (EC) with 98.9 µS/Cm. The mean standard deviation of 3.6 mg/L in acidity of pre and post monsoon seasons was also been a noted concern. Timing, extent of rainfall along with the usage had shown variations in the constituent’s concentrations. The study revealed that the standards for the harvested drinking water are compromised at some sites either in one or multiple physiochemical parameters. People in Port Vila continue to consume the harvested water due to cultural practices and beliefs related to rainwater. It was observed that proper management and adaptation to new technologies would yield better quality of the harvested water.

“…Water scarcity has become serious problem in several parts of the world, especially in developing nations like India Kumar and Jhariya (2017). In India, ever-increasing population exerts enormous pressure on the water resources of the country due to which per capita water availability is decreasing day by day Singh, Jha, and Chowdary (2017).…”

The objective of this study was to identify potential runoff storage zones based on the various physical characteristics of the Vishwamitri watershed using a GIS-based conceptual framework that combines through analytic hierarchy process using multi criteria decision-making method. The conceptual framework will help to identify potential runoff storage zones for water storage sites based on the various physical characteristics (rainfall, slope, land use/land cover, height above the nearest drainage, stream order, curve number, topographic wetness index) of the watershed. It was found out that 17% of the area is optimally suitable, 33.2% of the area is moderately suitable, 33.1% of the area is marginally suitable and 18.7% of the area is not suitable for water storage zones/ structures. Results will help concerned authorities in the proficient arrangement and execution of water-related plans and schemes, improve water shortage, reduce dependability on ground water and ensure sustainable water availability for local and agricultural purposes in the study area.
