Land subsidence and groundwater storage change assessment using InSAR and GRACE in the arid environment of Saudi Arabia
Najran region in Saudi Arabia has been affected by groundwater storage decline and consequent land subsidence for a long period of time. In this study, we utilized Sentinel-1 data for ground surface map**, t...

Open AccessHydrological assessment of some old dams in Saudi Arabia under the current climate, environmental conditions, and the use of the advanced technology
Dams were built in Saudi Arabia (SA) starting from the late fifties. The rainfall record at that time is rather short since the early rainfall records in the study area were in the mid-sixties. Therefore, due ...

Open AccessModeling variability of infiltration tests in ephemeral stream beds as a random function for uncertainty quantification
Infiltration processes are highly variable in space and time, and therefore, building reliable hydrological models without considering the variability is questionable. In this research, we propose a methodolog...

Open AccessUnderstanding the Non-Gaussian Nature of Linear Reactive Solute Transport in 1D and 2D
In the present study, we examine non-Gaussian spreading of solutes subject to advection, dispersion and kinetic sorption (adsorption/desorption). We start considering the behavior of a single particle and appl...

A Markov Chain Model for Subsurface Characterization: Theory and Applications
This paper proposes an extension of a single coupled Markov chain model to characterize heterogeneity of geological formations, and to make conditioning on any number of well data possible. The methodology is ...
