Water Recharge

KaengKhoi District (SaraburiProvince, Thailand) suffers from a surface water shortage due to increasing demand from domestic use and crop production, particularly in the drought season. Groundwater resources are an additional source of freshwater in this area, especially for agricul-tural purposes, but to be sustainable its usage should not exceed long-term groundwater recharge. Evaluation of the groundwater recharge potential is therefore essential to determine the sustain-able use level for groundwater resources. This study aimed to determine the groundwater re-charge potential using the geographic information system (GIS) around the Land Development Facilities of Chulalongkorn University at KaengKhoi District, Thailand. The hydrologic and geo-logic features affecting groundwater recharge potential into the groundwater system are the linea-ments, drainage density, lithology and land cover/land use. The weighting of these factors were derived from integration of the interrelationship of the major and minor effects of each contri-buting factor. Then GIS overlay was used to determine the influence of the hydrologic and geo-logic effects on total groundwater recharge potentiality, classified into five categories: very high, high, moderate, low and very low. The highest recharge potentialzone was located in the down-stream areas. The map generated revealed that about 50% of the study area had a medium ground-water recharge potential, mainly located in the eastern upstream part and the central area.

Ground Water Recharge

Groundwater quality in Gujarat state is highly variable and due to multiplicity of factors viz. influenced by direct sea water encroachment, inherent sediment salinity, water logging, overexploitation leading to overall deterioration in ground water quality, coupled with domestic and industrial pollution etc. The groundwater scenario in the state is not very encouraging due to imbalance between recharge and groundwater exploitation. Further, the demand for water has increased manifold owing to agricultural, industrial and domestic requirement and this has led to water scarcity in many parts of the state, which is likely to become more severe in coming future due to both natural and manmade factors. Therefore, sustainable development of groundwater resource requires precise quantitative assessment based on reasonably valid scientific principles. Hence, delineation of groundwater potential zones (GWPZ), has acquired great significance. <br><br> The present study focuses on the integrated Geospatial and Multi-Criteria Decision Making (MCDM) techniques to determine the most important contributing factors that affect the groundwater resources and also to delineate the potential zones for groundwater recharge. The multiple thematic layers of influencing parameters viz. geology, geomorphology, soil, slope, drainage density and land use, weightages were assigned to the each factor according to their relative importance as per subject experts opinion owing to the natural setup of the region. The Analytical Hierarchy Process (AHP) was applied to these factors and potential recharge zones were identified. The study area for the assessment of groundwater recharge potential zones is Mahi-Narmada inter-stream region of Gujarat state. The study shows that around 28 % region has the excellent suitability of the ground water recharge.

Water Recharge

Water is a basic need for humans and other living things. Various sources of water on this earth has formed a system of close interaction with the components of living things in it. Over the years, water resources have changed in terms of both quality and quantity. This can be due to population growth in addition to the natural changes in nature. The more narrow field of water absorption followed by high water consumption causes the supply of ground water reserves can be threatened. So, we need a mapping and ground water recharge calculations to assist in the monitoring of groundwater reserves.The method used in this research is the Water Balance (keseimbangan air)method. This method is based on any incoming rain water will be equal to the output evapotranspiration and runoff hereinafter this method is applied in the application. Factors affecting groundwater recharge the water balance method is precipitation, evapotranspiration and run off. Information og groundwater recharge is also displayed on the map using Google Map function are related to the database system to produce informative mapsCalculation of groundwater recharge is applied to the daily rainfall data input into the application which then included in the water balance equation method so it can be easy to determine the value of groundwater recharge. Groundwater recharge information can be displayed in the form of mapping, making them easier to understand visually.Based on testing, the highest recharge results of this research on the Kemput station is 1119,5 mm/year with rainfall of 2750 mm/year. Seyegan and Bronggang station is 1026,25 mm/year with rainfall of 2625 mm/year. Angin-angin and Prumpung station is 933 mm/year with rainfall of 2500 mm/year.

The water consumption in Bengaluru goes to 1853 Million Liter per Day (MLD) mainly sourced from Kaveri river and borewells and in result to produce abbot 1400 MLD of sewage. About 711 MLD is being treated water out come from 26 Secondary Treatment Plants (STP) against their capacity of 1360 MLD. About 462.9 MLD is recycled for various purposes and remaining 248.5MLD is allowed to flow in Sewage Water Drainage or in lakes allowed to mix with the sewage, making practically no use. The Bangalore Water Supply and Sewerage Board (BWSSB) has about 6 STPs in place for a capacity of 453.5 MLD in the Kormangla-Chelghatta valley (K&C Valley) catchment area. One of the best-known sewage recycling in present day in the country is 440 MLD Kormangla-Chelghatta valley project for drought prone Kolar and Chickballapur districts in Karnataka, India to reuse of treated water for ground water recharge and industries and then to agriculture. About 76 tanks have been filled till this date. From these tanks, treated water is allowed to recharge the ground water and then reused through open wells/ borewells for agriculture/ horticulture. No treated water is directly used from such tanks. The project has facilitated to change the socioeconomic status of the farmers, terrestrial, aquatic and marshy ecosystems of the area. The project is bringing change in symbiotic relations by exerting pressure for more sewage treatment at Bengaluru and in turn vegetables/agriculture products supply to it. It also fulfils the obligation of City to provide nutrient rich treated waste-water for farmers’ irrigation needs under distress conditions that they are facing due to drought and water shortage, who grow food and vegetables and thus ensuring symbiotic livelihood security for the farmers and food security for the city.

AbstractGroundwater is an important water source, especially in arid and semi-arid areas. Recharge is critical to managing and analyzing groundwater resources despite estimation difficulty due to temporal and spatial change. The study aim is to estimate annual groundwater recharge for the eastern Wasit Province part, Iraq. Where suffers from a surface water shortage due to the region's high elevation above Tigris River water elevation by about 60 m, it is necessary to search for alternative water sources, such as groundwater use. The spatially distributed WetSpass model was used to estimate the annual recharge. The inputs for the model were prepared using the ARC-GIS program, which includes the topography and slope grid, soil texture grid, land use, groundwater level grid, and meteorological data grids for the study area for the period (2014-2019). The result shows that the annual recharge calculated using the WetSpass model (2014-2019) varied of 0 to 65.176 mm/year at an average of 27.117 mm/year, about 10.8%, while the rate of the surface runoff was 5.2% and Evapotranspiration formed 83.33% of the annual rainfall rate of 251.192 mm. The simulation results reveal that the WetSpass model simulates the components of the hydrological water budget correctly. For managing and planning available water resources, a best grasp of the simulation of long-range average geographical distribution around the water balance components is beneficial.

Abstract In Kumamoto, Japan, about one million people depend for all their water on groundwater resources. Paddy fields and rice farming in the middle river watershed area make a large contribution to the groundwater recharge. In our research, an environmental measure (artificial flooding for groundwater recharge) conducted by local governments is evaluated. Hydrological measurement was conducted in a paddy plot in the area. A simple model of water distribution was developed on the basis of the field measurement. Then, drought risk in the paddy-field district was estimated using the model and GIS data. The results reveal that the fields with a high percolation rate of more than 30 mm/d result in inefficient use of irrigation water although they have large potential for groundwater recharge. In addition, the water distribution model suggests that environmental measures can increase the risk of water shortage in the paddy-field district due to the farmers' careless use of water.

Groundwater System

Osun drainage basin is one of the regions in Nigeria experiencing increasing population growth and rapid urbanization; and about 70% of the inhabitantsrely on shallow groundwater resources of the region. Change in land use/land cover is one of the significant factors controlling regional hydrology and groundwater resources, thus the continuous change in land use and land cover of the drainage basin will significantly affect the basin’s groundwater resources. There are 7 classified land use/land cover in the study area which are bare surfaces, built up area, crops/shrubs, forest, rock outcrops, water bodies and wetland. Applying WetSpass-M hydrological model, we predicted the effect of land use/land cover change on the groundwater recharge in Osun drainage basin, Nigeria between 1984-2015. The results revealed that the highest groundwater recharge of 48.56%, 33.64% and 37.29% occurred in forested area in 1984, 2000 and 2015, respectively. This result might be due to the influence of vegetation in slowing down the speed of running water across the forest area, that allows more infiltration and deep percolation into the water table to recharge the groundwater system. On the other hand, the least groundwater recharge of the total annual was on the rock outcrops, which are about 4% in 1984, 3% in 2000 and 2% in 2015. The least recharge found on rock outcrops is expected and may be attributed to the fact that infiltration can only occur around or on decomposed rock outcrop, which may result in minute recharge to the groundwater system. The mean annual groundwater recharge of the basin for the land use/land cover of 1984, 2000 and 2015 are476.54, 411.07 and 430.06 mm/y, respectively. Overall, for the 32 years period of investigation, change in land use/land cover accounts for only 10% reduction in mean groundwater recharge occurrence between 1984 and 2015. Also, there is a change in recharge pattern in the study area during this period because most often, change in land use/land cover is a transition from one land use/land cover class to another, and the recharge pattern is influenced based on the degree of transition that took place and the characteristics of the dominant land use/land cover at a particular area of the basin. Although, the 10% reduction in mean annual recharge appears minute, this might become pronounced if the current rate of deforestation in the drainage basin continues unabated. Therefore, proper land use allocation, regulated land development and afforestation in terms of planting of native trees that were lost through anthropogenic activities in the basin should be policy option for groundwater sustainability.

The larger population in the middle mountain region of Nepal is dependenton spring for domestic water use. Availability and flow regularity ofsprings rely on groundwater recharge (GWR) potential which is attributedto various natural and human factors. The present study is an attempt toexplore the GWR potential using GIS and Remote sensing (RS) methodin two watersheds of the far western middle mountains of Nepal. Spatialanalysis is carried out using a weighted overlay analysis of six factorsnamely, slope, lithology, lineament, drainage density, rainfall, and landcover/ land use. The result shows that only 16 percent of the total watershed area is under a very high recharge potential zone while 31 percent area falls under very low recharge potential. It is found that the distribution of existing spring sources is random concerning GWR potential. Water stress in Rel Gad watershed is evident which accentuates the propermanagement of recharge areas. The study concludes that the GIS RS toolis useful in identifying recharge potential zones. It aids to better planningfor increasing recharge potential. Proper management of recharge potentialarea and spring water sources direct the future water availability to fulfillthe increasing water need of the communities.

Hydrogeological Characteristics

The lower Khwae Hanuman sub-basin in Thailand suffers from water shortage during each dry season. As such, groundwater resources are an additional freshwater source in this region, in particular for cultivating activities. Thus, an understanding of the volume of groundwater recharge into the saturated zone is required. The objective of the study is to assess the groundwater recharge potential (GRP) using the weighted overlay analysis method by geographic information system (GIS) and finally checking the reliability of GRP map using observed specific capacity carried out by the Department of Groundwater Resources (DGR). The geological and hydrogeological features that affect groundwater potential are the lithology, land use, lineaments, drainage, slope, and soil. The weighting and rating of these six influencing factors were determined by assessing the interrelationship of the main and minor influences of each factor based on several literature reviews, followed by a weighted overlay analysis with GIS, in association with groundwater recharge. The GRP can be classified in descending order: high, moderate, low, and very low, where about 33.9 km2 (2.26% of the total area of 1,500 km2) had high recharge potentiality, located at the center of the area. Only 12.8% of the total precipitation (271.75 million m3/y or approximately 181.2 mm) infiltrated the groundwater aquifer, while the rest was lost by either surface runoff or evapotranspiration. Based on GRP sensitivity analysis index, lithology was the most efficient influencing factor in GRP mapping. Most groundwater wells (&gt;96% or 369 wells) were classified into the classes of low and moderated, which agree to the GRP zones. The results of calculating the area under the curve (AUC) of the receiver operating characteristic (ROC) curve were 86.0 percent, with relatively good predictive accuracy. The stable baseflow analysis would be used to confirm the amount of GRP by weighting overlay technique. Therefore, the GRP method can be applied in other areas, particular in similar hydrogeological characteristics. The first-hand recharge potential map and groundwater recharge information in this area can be used to establish an effective groundwater exploration program for agricultural activities; it is also used to appropriate sustainable yields from each groundwater basin to provide groundwater over the long-term, without negatively impacting the environment and without affecting the groundwater balance as it has recharge in the rainy seasons, which can use groundwater sustainably. It is in line with the sustainable development goals (SDGs) in goal number six of the UN.

Indirect physical methods of assess groundwater recharge rely on the measurement or estimation of soil physical parameters, which along with soil physical principles; can be used to estimate the potential or actual recharge. However, the deep percolation method uses a daily water- budget approach to simulate deep percolation. In this method, the model computes daily fluxes of water into and out of a volume extending from the top of foliage to the bottom of the root zone and accounts for changes in water content. In most environments, deep percolation is destined to recharge the saturated systems that are tapped by wells. Deep percolation technique was deployed to determine the rate of ground water recharge in the Voinjama region of Liberia, and also establish points of lineaments where wells can be dug for water supply. The perimeter of the hypothesized basin is about 28.9km while the length of the thalweg of the mainstream is about 11km. the average width of the basin area is 5.9km while the circumference of the equivalent circular area is 25.33km and compactness coefficient (R) of the basin is computed at 1.14. The elongation ratio (Er) is computed at 0.73km. The diurnal recharge computed from Deep Percolation was 6712.21 cm3 /km2 per annum. In conclusion, this study aids the restoration of water supply system destroyed during the war periods emphasizing the abundant water in the hydrological system and viable ground water recharge adequate for exploitation in a near uniform geology. Several faults and crevices scattered abroad the area were recorded indicating good lineament distribution and abundant aquifer recharge.Keywords: Hydrogeology, Deep Percolation Method, Groundwater, Recharge
