    ABSTRACT: Sedimentation may have a significant effect on the transport of solutes and environmental isotopes in sediment. The depth profiles of the Cl-, δ2H, and δ18O in a borehole in the aquifer-aquitard system in the Pearl River Delta (PRD), China were obtained by centrifuging the core sediment samples. A one-dimensional model based on the sedimentation and sea level changes of the PRD during the Holocene was built to investigate numerically the transport mechanisms of Cl-, δ2H, and δ18O. The sedimentation process was modeled as a moving boundary problem with the moving rate equal to the sedimentation rate. The model was calibrated and the parameters were obtained by comparing simulated and measured data. Very good agreement between all the three observed profiles and the simulated ones demonstrates the reliability of the model and the parameters. Simulation results show that the shapes of the curves are controlled by the combination of sedimentation and upper boundary conditions. Diffusion solely is adequate to reconstruct the observed profiles, which indicates that diffusion is the dominant vertical transport mechanism. The effective diffusion coefficient of the aquitard and the aquifer equals to 5.0 × 10-11 m2/s and 2.0 × 10-10 m2/s, respectively. The results of this study will help understand the transport mechanisms of solutes and environmental tracers in deltas with geology and hydrogeology similar to the PRD.

    ABSTRACT: To take into account the variability of the medium through which the groundwater flow takes place, we presented the groundwater flow equation within a confined aquifer with prolate coordinates. The new equation is a perturbed singular equation. The perturbed parameters is introduced and can be used as accurately replicate the variability of the aquifer from one point to another. When the perturbed parameter tends to zero we recover the Theis equation. We solved analytically and iteratively the new equation. We compared the obtained solution with experimental observed data together with existing solutions. The comparison shows that, the modified equation predicts more accurately the physical problem than the existing model

    ABSTRACT: Research on the water quality of urban runoff has so far focussed on the post-development phase of urban catchments, whereas water quality in developing areas under construction has remained less understood. The construction phase, however, may constitute a considerable source of diffuse pollution in urban areas. This study investigated mechanisms affecting water quality in residential areas during the construction and the post-construction phases. Water quality (suspended solids, total phosphorus, total nitrogen, chemical oxygen demand) and runoff were monitored over a period of five years in three catchments located in the city of Espoo in southern Finland. The catchments included an urbanising area under construction and low-density and high-density residential areas. The water quality was quantified in terms of event mean concentrations and loads. The key influential variables explaining water quality in a multiple linear regression analysis included hydrological variables (event volume and intensity), antecedent conditions and a variable describing the ongoing construction projects. Construction activities in the developing catchment had a profound impact on water quality. Inclusion of the variables describing activities, such as earth moving works, paving, house construction and temporary wastewater discharges, was necessary to explain water quality variations in the developing catchment. The importance of antecedent conditions as an explanatory variable depended on the site and pollutant in question.

    ABSTRACT: Glacier-fed river thermal regimes vary markedly in space and time; however, knowledge is limited of the fundamental processes controlling alpine stream temperature dynamics. To address the research gap, this study quantified heat exchanges at the water surface and bed of the Taillon glacier-fed stream, French Pyrénées. Hydro-meteorological observations were recorded at 15-min intervals across two summer melt seasons (2010 & 2011) and energy balance components were measured or estimated based on site-specific data. Averaged over both seasons, net radiation was the largest heat source (~80% of total flux); sensible heat (~13%) and friction (~3%) were sources also, while heat exchange across the channel - stream bed interface was negligible (<1%). Latent heat displayed distinct inter-annual variability and contributed 5% in 2010 compared to 0.03% in 2011. At the sub-seasonal scale, latent heat shifted from source to sink, possibly linked to the retreating valley snowline which changed temperature and humidity gradients. These findings represent the first, multi-year study of the heat exchange processes operating in a glacier-fed stream and, as well as providing fundamental process understanding, the research highlights the direct control antecedent (winter) conditions have on energy exchange and stream temperature during summer months. In particular the timing and volume of snowfall/snowmelt can drive thermal dynamics by: (1) altering the length of the stream network exposed to the atmosphere; and, (2) controlling the volume and timing of cold water advection downstream. Finally, this study highlights the need to develop long term hydro-meteorological monitoring stations to improve understanding of these highly dynamic, climatically sensitive systems.

    ABSTRACT: The groundwater hydrochemical behaviour of the Langueyú creek basin (Argentina) has been evaluated through a systematic survey, followed by application of hydrological and chemometric multivariate techniques. Ten physicochemical parameters were determined in groundwater samples collected from 26 wells during 4 sampling campaigns (June, 2010; October, 2010; February, 2011 and June, 2011), originating a tridimensional experimental dataset X. Univariate statistical and graphical hydrochemical tools (contour maps and Piper diagrams) applied to individual campaigns, allowed to reach some preliminary conclusions. However, a best visualization of the aquifer behaviour was achieved by applying Principal Component Analysis (MA-PCA) and N-way PCA procedures, PARAFAC and Tucker3. Results were consistent with two-term models, being Tucker3 [2 2 1] the most adequate, explaining a large amount of the dataset variance (50.7 %) with a low complexity. The first Tucker3 [1 1 1] interaction (38.2% of variance) is related with (i) calcium/magnesium vs. sodium/potassium ion exchange processes; (ii) an increase of ionic concentration and (iii) a decrease of nitrate pollution, all processes along the direction of the groundwater flow. The second [2 2 1] interaction (12.5% of variance), accounts for the predominant role played by conductivity, bicarbonate and magnesium in the dataset. The seasonal variations are closely related to concentration/dilution phenomena originated by the variations of the phreatic levels, although this point will require additional sampling to establish a definitive hydrochemical model.

    ABSTRACT: A guiding principle in hydrological modelling should be to keep the number of calibration parameters to a minimum. A reduced number of parameters to be calibrated, while maintaining the accuracy and detail required by modern hydrological models, will reduce parameter and model structure uncertainty and improve model diagnostics. In this study, the dynamics of runoff are derived from the distribution of distances from points in the catchments to the nearest stream. This distribution is unique for each catchment and can be determined from a geographical information system. The distribution of distances, will, when a celerity of (subsurface) flow is introduced, provide a distribution of travel times, or a unit hydrograph (UH). For spatially varying levels of saturation deficit, we have different celerities and, hence, different UHs. Runoff is derived from the superposition of the different UHs. This study shows how celerities can be estimated if we assume that recession events represent the combined UHs for different levels of saturation deficit. A new soil moisture routine which estimates saturated and unsaturated volumes of subsurface water and with only one parameter to calibrate is included in the new model. The performance of the new model is compared with that of the Swedish HBV model and is found to perform equally well for eight Norwegian catchments although the number of parameters to be calibrated in the module concerning soil moisture and runoff dynamics is reduced from seven in the HBV model to one in the new model. It is also shown that the new model has a more realistic representation of the subsurface hydrology. Copyright © 2013 John Wiley & Sons, Ltd.

    ABSTRACT: In the present study, a semi-distributed hydrological model soil and water assessment tool (SWAT) has been employed for the Ken basin of Central India to predict the water balance. The entire basin was divided into ten sub basins comprising 107 hydrological response units on the basis of unique slope, soil and land cover classes using SWAT model. Sensitivity analysis of SWAT model was performed to examine the critical input variables of the study area. For Ken basin, curve number, available water capacity, soil depth, soil evaporation compensation factor and threshold depth of water in the shallow aquifer (GWQ_MN) were found to be the most sensitive parameters. Yearly and monthly calibration (1985–1996) and validation (1997–2009) were performed using the observed discharge data of the Banda site in the Ken basin. Performance evaluation of the model was carried out using coefficient of determination, Nash–Sutcliffe efficiency, root mean square error-observations standard deviation ratio, percent bias and index of agreement criterion. It was found that SWAT model can be successfully applied for hydrological evaluation of the Ken basin, India. The water balance analysis was carried out to evaluate water balance of the Ken basin for 25 years (1985–2009). The water balance exhibited that the average annual rainfall in the Ken basin is about 1132 mm. In this, about 23% flows out as surface run-off, 4% as groundwater flow and about 73% as evapotranspiration. Copyright © 2013 John Wiley & Sons, Ltd.
