In this study, a geostatistically based estimator is developed that simultaneously includes all observed transient hydrographs from hydraulic tomography to map aquifer heterogeneity. To analyze data, data preprocessing procedure (including diagnosing and wavelet denoising analysis) recommended. A least squares approach then introduced estimate effective parameters spatial statistics of heterogeneity are the required inputs for geostatistical estimator. Since does not completely remove noise...
Abstract An increasing impervious area is quickly extending over the Wu‐Tu watershed due to endless demands of people. Generally, paving a major result urbanization and more recently has had potential produce enormous flood disasters than those past. In this study, 40 available rainfall–runoff events were chosen calibrate applicable parameters models determine relationships between surfaces calibrated parameters. Model inputs came from outcomes block kriging method non‐linear programming...
Three conceptual models are evaluated for estimating transmissivity ( T ) fields using data from sequential pumping tests at a field site and similar simulated in synthetic aquifer. The three approaches (1) an equivalent homogeneous approach, (2) heterogeneous approach based on single test, (3) joint interpretation of the (i.e., hydraulic tomography, HT). They basis their abilities to obtain representative estimates aquifer and, more importantly, ability predict drawdown distributions...
Abstract Hydraulic tomography (HT) has become a mature aquifer test technology over the last two decades. It collects nonredundant information of heterogeneity by sequentially stressing at different wells and collecting responses other during each stress. The collected is then interpreted inverse models. Among these models, geostatistical approaches, built upon Bayesian framework, first conceptualize hydraulic properties to be estimated as random fields, which are characterized means...
While hydraulic tomography (HT) is a mature aquifer characterization technology, its applications to characterize hydrogeology of kilometer-scale fault and fracture zones are rare. This paper sequentially analyzes datasets from two new pumping tests as well those previous analyzed by Illman et al. (2009) at fractured granite site in Mizunami, Japan. Results this analysis show that one side zone used the study led inaccurate mapping zones. Inclusion (one which was conducted on other fault)...
The removal of Reactive Black 5 (RB5) using chemically modified banana peel powder (CMBPP) from aqueous solution was dealt with in the present investigation. Factors affecting adsorption RB5 (like pH solution, agitation speed, initial concentration RB5, contact time and temperature) were investigated. FTIR, SEM-EDX, BET Elemental analysis characterized adsorbent material. Adsorption kinetic results evaluated by non-linear pseudo-second-order model fitted well showed good correlation...
Aminated avocado seed powder (AASP)—an eco-friendly novel adsorbent has been used for the removal of Acid Yellow 17 (AY 17) and Amaranth (AMR) from an aqueous phase. The AASP (before after adsorption) was systematically characterized by different analytical techniques such as FT-IR, FESEM, EDX, N2 adsorption-desorption analysis. Non-linear form various kinetic (PFO PSO) isotherm (Langmuir Freundlich) models were to examine adsorption behavior AY AMR onto AASP. well illustrated PSO model...
This paper first visits uniqueness, scale, and resolution issues in groundwater flow forward modeling problems. It then makes the point that non-unique solutions to inverse problems arise from a lack of information necessary make well defined. Subsequently, it presents conditions for well-defined problem. They are full specifications (1) flux boundaries sources/sinks, (2) heads everywhere domain at least three times (one which is t = 0), with head change those being nonzero transient flow....

Further,...
Past research on the hydrogeological parameters of local aquifer has rarely utilized sequential pumping test (SPT) drawdown data collected from multiple tests at same experimental site to comprehensively characterize distribution fields transmissivity (𝑇) and storage coefficient (S), as well their reciprocity. To address this gap, study aims collect SPT an located northeast corner field Yunlin University Science Technology, Douliu City, County. The dataset spans five conducted in...
Traditional temperature sensors often lack the capability for continuous, high-resolution soil monitoring. This study employs Fiber Optic Distributed Temperature Sensing (FO-DTS) to establish a large-scale, horizontal experimental site observing shallow variations with high spatial resolution. The research investigates distribution of water infiltration in retention pond by analyzing layers. near Douliu Irrigation Gukeng Township, central Taiwan, encompasses 2-hectare comprising precipitate...
Although portable x-ray fluorescence (XRF) technology is widely accepted for environmental use in field screening test regarding the analytical approach, it needs to be evaluated with sufficient data and meet its performance characteristics employable decision making purposes. Usually, an XRF sample, most interesting query is: How reliable technique detecting different targeted metals soil? This study presents pairwise comparisons between inductively coupled plasma atomic emission...
