Abstract:
Abstract. The estimation of groundwater recharge is of paramount importance to assess the sustainability of groundwater use in aquifers around the world. Estimation of the recharge flux, however, remains notoriously difficult. In this study the application of nonlinear transfer function noise (TFN) models using impulse response functions is explored to simulate groundwater levels and estimate groundwater recharge. A nonlinear root zone model that simulates recharge is developed and implemented in a TFN model and is compared to a more commonly used linear recharge model. An additional novel aspect of this study is the use of an autoregressive–moving-average noise model so that the remaining noise fulfills the statistical conditions to reliably estimate parameter uncertainties and compute the confidence intervals of the recharge estimates. The models are calibrated on groundwater-level data observed at the Wagna hydrological research station in the southeastern part of Austria. The nonlinear model improves the simulation of groundwater levels compared to the linear model. The annual recharge rates estimated with the nonlinear model are comparable to the average seepage rates observed with two lysimeters. The recharges estimates from the nonlinear model are also in reasonably good agreement with the lysimeter data at the smaller timescale of recharge per 10 d. This is an improvement over previous studies that used comparable methods but only reported annual recharge rates. The presented framework requires limited input data (precipitation, potential evaporation, and groundwater levels) and can easily be extended to support applications in different hydrogeological settings than those presented here.

Abstract:
Accurate estimation of groundwater recharge is extremely important for propermanagement of groundwater systems. Attempts have been made by various researchers torelate impact of various parameters on groundwater recharge. In the present study, amethodology based on spatial distribution of parameters has been developed forunderstanding affect of rainfall and vegetation density on groundwater recharge.Normalized Difference Vegetation Index (NDVI) has been used as an indicative parameterfor vegetation density. Raster layers of recharge and various parameters were created for thestudy area and simultaneous values for these parameters were retrieved at the cell level.Zonal analysis was then carried out to understand affect of these parameters ongroundwater recharge. It is observed that the value of recharge increases up to a certainvalue of NDVI, beyond which it starts decreasing with further increase in value of NDVI.The study also reveals a linear trend between groundwater recharge and rainfall. The resultof this study does not provide method of calculating recharge by using single parametersuch as rainfall or NDVI, however, it explores affect of variation in these parameters ongroundwater recharges. The study provides a new insight into the complex interrelationshipbetween groundwater recharge and vegetation density.

Abstract:
Dryland salinity is recognised as a major environmental concern on the Liverpool Plains in north-eastern New South Wales. Previous hydrogeological and dryland salinity studies have highlighted the importance of adopting appropriate farming systems to reduce recharge into shallow aquifers. In this study, we applied the cropping systems model PERFECT to investigate the effects of climate, soil, and land use on recharge. Model inputs were derived from a range of sources including historical weather data, soil survey data, and information from landholder surveys. We investigated 47 different soils identified in a published soil survey covering approximately 280 000 ha of the Liverpool Plains. This study demonstrated a significant variation in soil physical properties and estimated recharge within soil types and illustrates the dangers of generalising soils into broad groupings. For example, under a wheat-sorghum rotation, predicted average annual recharge for soils classified as black earths ranged from 28 to 80 mm. Similar variability of predicted drainage is evident within other Great Soil Groups. The results reveal that response cropping alone will not significantly reduce recharge for all soils. Considering one black earth soil, average annual recharge is predicted to be 48 mm for a wheat-sorghum rotation, 22 mm for a response cropping rotation, and 8 mm for a lucerne{response cropping rotation. Therefore, including lucerne within a response cropping system is of benfit in reducing recharge. For all soil types, least recharge is predicted for permanent pasture but this land use is not an attractive option to farmers given the diversity of farming systems in the region. However, for some soils, continuous pasture is appropriate because excessive recharge is estimated for all cropping systems. This study has extended previous modelling work in the region as it considered a much wider range of soil types and cropping systems than previously investigated. Such a modelling approach permits the quantification of the effects of climate, soil type, and land use on recharge below the root-zone.

Abstract. Estimating the change in groundwater recharge from an introduced artificial recharge system is important in order to evaluate future water availability. This paper presents an inverse modeling approach to quantify the recharge contribution from both an ephemeral river channel and an introduced artificial recharge system based on floodwater spreading in arid Iran. The study used the MODFLOW-2000 to estimate recharge for both steady- and unsteady-state conditions. The model was calibrated and verified based on the observed hydraulic head in observation wells and model precision, uncertainty, and model sensitivity were analyzed in all modeling steps. The results showed that in a normal year without extreme events, the floodwater spreading system is the main contributor to recharge with 80% and the ephemeral river channel with 20% of total recharge in the studied area. Uncertainty analysis revealed that the river channel recharge estimation represents relatively more uncertainty in comparison to the artificial recharge zones. The model is also less sensitive to the river channel. The results show that by expanding the artificial recharge system, the recharge volume can be increased even for small flood events, while the recharge through the river channel increases only for major flood events.

Abstract:

Kunskap om grundvattenbildningen är nödvändig för att man ska kunna förutsäga konsekvenserna av grundvattenuttag och underjordsbyggande. Grundvattenbildningen i berggrunden är dock svår att uppskatta. Syftet med avhandlingen var att öka förståelsen av grundvattenbildningen i kristallin berggrund, att undersöka hur grundvattenbildningen ska uppskattas samt att utveckla nya modeller för att beskriva grundvattenbildningen. Studien grundades på tre angreppssätt: grundvattendatering med freoner (CFC), geohydrauliska observationer och matematisk modellering.

Koncentrationerna av CFC-11 och CFC-113 befanns vara låga i det undersökta berggrundvattnet, vilket i kombination med låga syrgashalter tyder på anaerob nedbrytning. Koncentrationerna av CFC-12 och tritium överensstämde ganska väl, vilket betyder att den skenbara åldern kan vara den sanna åldern. Resultaten tyder på att CFC-datering inte är pålitlig i skogsmiljöer med finkornigt jordtäcke.

Vid nederbörd observerades ett snabbt gensvar i den hydrauliska potentialen i den studerade bergakviferen, trots det 10 m mäktiga moräntäcket. En avsevärd del av de observerade potentialvariationerna befanns vara belastningseffekter, som inte innebar någon magasinsförändring eller något vattenflöde. Berggrundens belastningseffektivitet uppskattades, ur potentialens svar på lufttrycksförändringar, till 0,95. Ytbelastningen beräknades från mätningar av lufttryck, vatten i jordtäcket och snö. Omkring 20 % av årstidsvariationen hos den hydrauliska potentialen uppskattades bero på enbart belastningsförändringar. En enkel begreppsmässig modell kunde användas för att simulera den observerade hydrauliska potentialen. För att beskriva enskilda grundvattenbildningstillfällen på bästa sätt var det nödvändigt att ta hänsyn till effekten av ytbelastningen.

Numeriska experiment gjordes med en modell av en jord–bergprofil. När berget modellerades som ett heterogent kontinuum bildades omättade zoner i berget vid stora hydrauliska gradienter. Fenomenet uppträdde i områden där låggenomsläppliga zoner låg uppströms höggenomsläppliga zoner, och ledde till minskad hydraulisk konduktivitet i berget.


Knowledge about the groundwater recharge is essential for the prediction of impacts of groundwater withdrawal and underground construction. Recharge in the bedrock is, however, difficult to estimate. The objectives of this thesis were to increase the understanding of groundwater recharge in crystalline bedrock, to investigate how the recharge could be estimated, and to develop new models to describe the recharge. The study was based on three approaches: groundwater dating using chlorofluorocarbons (CFCs), geohydraulic field measurements, and mathematical modelling.

Low concentrations of CFC-11 and CFC-113 were found in the bedrock groundwater, which in combination with low dissolved-oxygen levels indicated anaerobe degradation. The CFC-12 and tritium concentrations agreed fairly well, which means that apparent ages could be true ages. The results suggest that CFC dating may not be reliable at forested, humid sites covered by fine-grained soil.

A quick response in hydraulic head to precipitation was observed in the studied bedrock, despite the 10-m thick till cover. A substantial portion of observed head variations was found to be loading effects, involving no storage changes or water flow. The loading efficiency of the bedrock was estimated, from the air-pressure response, to be 0.95. The surface loading was calculated from measurements of air pressure, water in the soil, and snow. About 20% of the seasonal variation of the hydraulic head was estimated to be related to loading changes only. A simple conceptual model could be used to simulate the observed hydraulic heads. The loading effect had to be included to properly describe individual recharge events.

Numerical experiments were performed with a soil–bedrock profile. When the rock was modelled as a heterogeneous continuum, unsaturated zones developed at high hydraulic gradients. The phenomenon appeared in areas where low-conductive zones were located upstream of high-conductive zones, decreasing the effective hydraulic conductivity of the material.

Quantifying and characterizing groundwater recharge are critical for water resources management. Unfortunately, low recharge rates are difficult to resolve in dry environments, where groundwater is often most important. Motivated by such concerns, this thesis presents a new probabilistic approach for analyzing diffuse recharge in semiarid environments and demonstrates it for the Southern High Plains (SHP) in Texas. Diffuse recharge in semi-arid and arid regions is likely to be episodic, which could have important implications for groundwater. Our approach makes it possible to assess how episodic recharge can occur and to investigate the control mechanisms behind it. Of the common recharge analysis methods, numerical modeling is best suited for considering control mechanisms and is the only option for predicting future recharge. However, it is overly sensitive to model errors in dry environments. Natural chloride tracer measurements provide more robust indicators of low flux rates, yet traditional chloride-based estimation methods only produce recharge at coarse time scales that mask most control mechanisms. We present a data assimilation approach based on importance sampling that combines modeling and data-based estimation methods in a consistent probabilistic manner. Our estimates of historical recharge time series indicate that at the SHP data sites, deep percolation (potential recharge) is indeed highly episodic and shows significant interannual variability. Conditions that allow major percolation events are high intensity rains, moist antecedent soil conditions, and below-maximum root density. El Niño events can contribute to interannual variability of percolation by bringing wetter winters, which produce modest percolation events and provide wet antecedent conditions that trigger spring episodic recharge.
(cont.) Our data assimilation approach also generates conditional parameter distributions, which are used to examine sensitivity of recharge to potential climate changes. A range of global circulation model predictions are considered, including wetter and drier futures. Relative changes in recharge are generally more pronounced than relative changes in rainfall, demonstrating high susceptibility to climate change impacts. The temporal distribution of rainfall changes is critical for recharge. Our results suggest that increased total precipitation or higher rain intensity during key months could make strong percolation peaks more common.

Abstract:
Quantification of groundwater recharge is a crucial prerequisite for sustainable groundwater resource management, particularly in semi-arid areas where there are large demands for groundwater supplies. This research presents an alternative approach for recharge estimation based on the soil water balance technique. The purpose is to develop a model which provides a suitable balance between physical credibility and data which realistically can be gathered. A spreadsheet model was written based on the conceptual representation of the principal physical processes which actually affect recharge in a semi-arid area. Alternative procedures were included in order to represent: (a) the estimation of runoff, (b) the inclusion of the period with predominant bare soil evaporation and (c) the accounting for evapotranspiration following rainfall on dry soil. The model was tested using real data from a semi-arid region (Northeast Nigeria) making use of selected periods of days and years in order to illustrate the principal model characteristics. The results were presented in the form of diagrams and graphs helping to visualise the interactions between the physical components and the effect of the additional procedures on recharge estimation. The credibility of the model was investigated using an alternative concept of 'analysis of plausibility'. This concept makes use of as wide as possible a range of quantitative and qualitative information from the hydrological system in order to verify the robustness of the model when extensive datasets required by conventional validation techniques are not available. The results suggested that the modelled recharge is physically sound and it is in line with the overall determination of recharge in semi-arid areas by a range of methods. The soil water balance model was utilised to explore important aspects of recharge in semi-arid regions showing the effect of the field variability on the model's output. The preliminary results show that the developed concept reasonably represents the inherent field variability, thus corroborating the strength of the approach for recharge estimation in semi-arid regions.

Abstract:

This dissertation reports on the methods and results of a three-phased investigation to estimate the annual volume of ephemeral-channel-focused groundwater recharge attributable to urbanization (urban-enhanced groundwater recharge) in the Sierra Vista subwatershed of southeastern Arizona, USA. Results were used to assess a prior estimate.

The first research phase focused on establishment of a study area, installation of a distributed network of runoff gages, gaging for stage, and transforming 2008 stage data into time series of volumetric discharge, using the continuous slope-area method. Stage data were collected for water years 2008 - 2011.

The second research phase used 2008 distributed runoff data with NWS DOPPLER RADAR data to optimize a rainfall-runoff computational model, with the aim of identifying optimal site-specific distributed hydraulic conductivity values and model-predicted infiltration.

The third research phase used the period-of-record runoff stage data to identify study-area ephemeral flow characteristics and to estimate channel-bed infiltration of flow events. Design-storm modeling was used to identify study-area predevelopment ephemeral flow characteristics, given the same storm event. The difference between infiltration volumes calculated for the two cases was attributed to urbanization. Estimated evapotranspiration was abstracted and the final result was equated with study-area-scale urban-enhanced groundwater recharge. These results were scaled up to the Sierra Vista subwatershed: the urban-enhanced contribution to groundwater recharge is estimated to range between 3270 and 3635 cubic decameters (between 2650 and 2945 acre-feet) per year for the period of study. Evapotranspirational losses were developed from estimates made elsewhere in the subwatershed. This, and other sources of uncertainty in the estimates, are discussed and quantified if possible.

Abstract:
Il seguente elaborato è frutto del lavoro di ricerca, della durata di cinque mesi, svolto presso il Department of Catchment Hydrology del centro di ricerca UFZ (Helmholtz-Zentrum für Umweltforschung) con sede in Halle an der Saale, Germania. L’obiettivo della Tesi è la stima della ricarica della falda acquifera in un bacino idrografico sprovvisto di serie di osservazioni idrometriche di lunghezza significativa e caratterizzato da clima arido. Il lavoro di Tesi è stato svolto utilizzando un modello afflussi-deflussi concettualmente basato e spazialmente distribuito. La modellistica idrologica in regioni aride è un tema a cui la comunità scientifica sta dedicando numerosi sforzi di ricerca, presentando infatti ancora numerosi problemi aperti dal punto di vista tecnico-scientifico, ed è di primaria importanza per il sostentamento delle popolazioni che vi abitano. Le condizioni climatiche in queste regioni fanno sì che la falda acquifera superficiale sia la principale fonte di approvvigionamento; una stima affidabile della sua ricarica, nel tempo e nello spazio, permette un corretta gestione delle risorse idriche, senza la quale il fabbisogno idrico di queste popolazioni non potrebbe essere soddisfatto. L’area oggetto di studio è il bacino idrografico Darga, una striscia di terra di circa 74 km2, situata in Cisgiordania, la cui sezione di chiusura si trova a circa 4 kilometri dalla costa del Mar Morto, mentre lo spartiacque a monte, ubicato a Nord-ovest, dista circa 3 kilometri dalla città di Gerusalemme.

Abstract:
A exploração acelerada das águas subterrâneas pode acarretar em problemas de disponibilidade de água. Esse problema tende a ser acentuado devido as mudanças no clima previstas para as próximas décadas. Nesse contexto, este trabalho buscou avaliar os possíveis impactos das mudanças climáticas e do uso do solo sobre níveis de água subterrânea em zona de afloramento do Sistema Aquífero Guarani. Foram utilizadas simulações de Modelos de Circulação Global (MCG) como dados de entrada para um modelo transiente de fluxo hídrico subterrâneo, visando avaliar o comportamento dos nveis de água sob diferentes condições climáticas. Este modelo foi calibrado utilizando dados de níveis freáticos em seis poços localizados na bacia do Ribeirão da Onça (BRO). A partir de dados climáticos observados, estimou-se a recarga, usada como input no modelo matematico, em diversos tipos de cultura por meio do balanço hídrico. As maiores alterações nas médias pluviométricas mensais foram projetadas, pela maioria dos modelos climáticos, para ocorrer no perodo seco. No perodo chuvoso, as previsões indicaram que essas médias devem diminuir em torno de 50%. Quase 70% dos cenários climáticos geraram, no modelo transiente, variações dos nveis freáticos abaixo daqueles medidos no monitoramento entre 2004 e 2011. Em setores da área de estudo, o rebaixamento da superfície potenciométrica, simulada sob condições climáticas mais extremas previstas por alguns modelos, ultrapassou 10 m. Os cenários mais otimistas, embora tenham resultado em elevações dos níveis de água em mais metade da BRO, também geraram rebaixamentos de até 5 m. Os resultados reforçam a necessidade do contínuo monitoramento hidrogeológico, principalmente em áreas de recarga do SAG, e do desenvolvimento de outros trabalhos que quantiquem os impactos das mudanças climáticas, aplicando diferentes métodos de estimativa de recarga e downscaling.
The unsustainable use groundwater in many countries might cause water availability restrictions. Such issues are likely to worsen due to changes in climate, predicted for the incoming decades. In this context, the objective of this work was to assess possible climate and land use changes impacts on groundwater levels in the Guarani Aquifer System\'s (GAS) outcrop zone. Global Climate Models\' (GCM) outputs were used as inputs in a transient ux groundwater model. Thus, groundwater table uctuation could be evaluated under distinct climatic conditions. Six monitoring wells, located in the Ribeir~ao da Onca basin (ROB), provided water table measurements to calibrate the groundwater model. Using observed climatic data, a water budget method was applied to estimate recharge in dierent types of land uses. Statistically downscaled future climate scenarios were used as inputs in that same recharge model, which provided the inputs for SPA. Most of the GCMs used here predict temperature arises over 2°C. Major monthly rainfall mean changes are projected by the GCM great majority to take place in the dry season. During wet seasons, the predictions indicate those means might experience around 50% decrease. Water table variations, derived from the transient model under almost 70% of the climate scenarios, were below of those measured between 2004 and 2011. Few GCM predicted more extreme climate scenarios. In some regions of the study area and under these conditions, groundwater surface would decline more than 10 m. Although more optimistic scenarios resulted in an increase of groundwater levels in more than half of ROB, these would cause up to 5 m water table decline. The results reinforce the need for a permanent hydrogeological monitoring, mainly in the GAS recharge areas, along with the development of other climate change impacts assessment works using dierent downscaling and recharge estimates methods.

Abstract:
In the Horonobe area of northern Hokkaido, the Japan Atomic Energy Agency has been carrying out various hydrological observations to estimate the recharge rate. Subsurface earth temperature and soil moisture content have been observed at HGW-1 site (GL-0.7m to GL-2.3m, since 2005) and Hokushin Meteorological Station (GL-0.1m to GL-1.1m, since 2008). The results have revealed groundwater infiltration and recharge occurring throughout year, the shallow groundwater-infiltration velocity depending on the depth and the position of the Zero Flux Plane. For the estimation of boundary conditions in groundwater flow simulation, in this study, the shallow groundwater-flow system has been examined qualitatively on the basis of the variation of the subsurface earth temperature and the soil moisture content. In the future, it is necessary to quantitatively assess the shallow groundwater infiltration and recharge rate, the intermediate runoff, and the evapotranspiration based on the observed data of the weighing lysimeter, and the other measurement stations in the area.
