Abstract. Quantifying impacts on the environment and human health is a critical requirement for geological subsurface utilisation projects. In practice, an easily accessible interface operators regulators needed so that risks can be monitored, managed, mitigated. The primary goal of this work was to create environmental hazards quantification toolkit as part risk assessment in-situ coal convers...

Choosing a suitable process-oriented eco-hydrological model is essential for obtaining reliable simulations of hydrological processes. Determining soil hydraulic and solute transport parameters another fundamental prerequisite. Research discussing the impact considering evaporation fractionation on parameter estimation practical applications isotope models limited. In this study, we analyzed re...

The general expressions for the time-dependent ensemble averages of the second spatial moments ^A& and the effective dispersivities g, defined as (1/ 2m)(d^A&/dt) where m is the magnitude of the mean flow velocity m, are evaluated in order to study the effect of initial plume size on ^A& and g in three-dimensional heterogeneous isotropic aquifers under the first-order approximation to the parti...

The connectivity of the Barat Cave underground river system needs to be known support implementation proper environmental management so that water resources can maintained sustainably. However, mapping paths is often hindered by conditions narrow cave passages, a barrier blocking flow (siphon), deep lakes, waterfalls, as well filled with water. This research was conducted in Cave, Karangbolong ...

ity D/v (L), that can be related solely to characteristics of the porous medium (Fried and Combarnous, Dispersivity ( ) is a required input parameter in solute-transport 1971). Dispersivity is a required input parameter in conmodels based on the advection-dispersion equation (ADE). Normally is obtained from miscible-displacement experiments. This depentaminant transport models based on the ADE ...

The hierarchical MoS2/CoNi composites were successfully synthesized by a two-step hydrothermal method. large surface area of the MoS2 enhances dispersivity CoNi nanoparticles and formation abundant interfaces, which make an important contribution to dielectric loss, introduction improves impedance matching introduces magnetic can improve absorption performance electromagnetic waves. Through cal...
