Abstract. Advances in high-performance parallel computing have significantly enhanced the speed of large-scale hydrological simulations. However, diversity and rapid evolution available computational systems hardware devices limit model flexibility increase code maintenance efforts. This paper introduces SERGHEI-RE, a three-dimensional, variably saturated subsurface flow simulator within SERGHEI framework. SERGHEI-RE adopts Kokkos-based portable parallelization framework SERGHEI, which...
Statistics that capture the directional dependence of baryon distribution in cosmic web enable unique tests cosmology and astrophysical feedback. We use constrained oriented stacking thermal Sunyaev-Zel'dovich (tSZ) maps to measure anisotropic hot gas $2.5-40$ Mpc away from galaxy clusters embedded massive filaments superclusters. The cluster selection orientation (at a scale $\sim15$ Mpc) Dark Energy Survey (DES) Year 3 data, while expanded tSZ Atacama Cosmology Telescope Data Release 6...
1-day vulnerabilities in binaries have become a major threat to software security. Patch presence test is one of the effective ways detect vulnerability. However, existing patch works do not perform well practical scenarios due interference from various compilers and optimizations, patch-similar code blocks, irrelevant functions stripped binaries. In this paper, we propose novel approach named PLocator, which leverages stable values both its context, extracted control flow graph, accurately...
The weathering of shale exerts an important control on the hydrochemical fluxes to river systems, thus influencing global carbon, nutrient, and geochemical cycles. However, quantitative understanding its impact biogeochemical cycles remains inadequate due complex interplay between hydrological, biogeochemical, physical processes. In this study, we develop a novel modeling approach quantitatively interpret long-term chemical occurring since last glaciation period (15,000 years) leading...
This paper describes a new modeling framework for microscopic to reservoir-scale simulations of hydraulic fracturing and production. The approach builds upon fusion two existing high-performance simulators behavior: the GEOS code hydromechanical evolution during stimulation TOUGH+ multi-phase flow are informed by experimental studies at laboratory scale incorporate important micro-scale mechanical processes chemical reactions occurring within fractures, shale matrix, fracture-fluid...
Abstract Total dissolved gas supersaturation (TDGS) produced by flood flows over a high dam has negative consequences on downstream fish. Reducing the total (TDG) levels and/or providing adequate low‐TDGS fish shelter areas remains challenge. The presence of low‐TDG‐saturation (LTS) zone at river confluences can protect from harmful TDG levels, but effects confluence hydrodynamics TDGS distribution are not well understood. In this study, three‐dimensional (3D) hydrodynamic simulations...
Fracture injection/shut-in tests are commonly used to measure the state of stress in subsurface. Injection creates a hydraulic fracture (or some cases, opens preexisting fracture), and then pressure after shut-in is monitored identify closure. Different interpretation procedures have been proposed for estimating closure, sometimes yield significantly different results. In this study, direct, in-situ strain measurements observe reopening The were performed as part EGS Collab project,...
