Control of Topology of Water Fluxes in Arid Agriculture: Amalgamation of Subsurface Irrigation, Managed Aquifer Recharge and Engineered Soil Substrat

Kacimov Anvar Rashidovich; Al-Ismaily Said; Al-Maktoumi Ali; Obnosov Yurii Viktorovich (2016)

We present the results of field-, farm- observations and experiments, as well as mathematical modeling of optimal control of descending, ascending and lateral water fluxes (viz., evapotranspiration, infiltration, seepage ...
Dipolic MAR "bubble" inside confined brine formation or floating "lens" on top of unconfined saline aquifer.

Kacimov Anvar; Obnosov Yurii Viktorovich; Al-Maktoumi Ali (2019)

In arid desert environments, MAR sites are often characterized by high salinity of the ambient groundwater and intensive evaporation. We present mathematical modeling of two MAR scenarios: 1) injection-abstraction of fresh ...
Modelign of seepage through embankments of earth-filled recharge dams in Oman: steady and transient regimes

Kacimov Anvar Rashidovich; Al-Maktoumi Ali; Obnosov Yurii Viktorovich (2016)

Аналитически исследована линейная фильтрация через ядро плотины и примыкающие к нему сильнопористые присыпки. Течение в ядре анализируется с помощью конформного отображения пентагона в области годографа скорости на ...
Profiling Ponded Soil Surface in Saturated Seepage Into Drain-Line Sink: Kalashnikov's Method of Lateral Leaching Revisited

Kacimov Anvar Rashidovich; Obnosov Yurii Viktorovich (2022)

Two boundary value problems are solved for potential steady-state 2-D Darcian seepage flows towards a line sink in a homogeneous isotropic soil from a ponded land surface, which is not flat but profiled with the aim of ...
Seepage-Evaporation Controlled Depletion of Initially Water-Filled Reservoirs on Earth and Mars: Analytic Versus HYDRUS Modeling

Kacimov Anvar Rashidovich; Obnosov Yurii Viktorovich; Šimůnek Jirka (2021)

Analytical solutions are obtained for water extinction from an axisymmetric crater, filled at t ( 0 and depleted by evaporation and transient infiltration into a Gardner or capillarity-free homogeneous soil during the time ...
Size and Shape of Steady Seawater Intrusion, Sharp-Interface Wedge: the Polubarinova-Kochina Analytical Solution to the Dam Problem Revisited

Obnosov Yurii Viktorovich; Kacimov Anvar Rashidovich (2016)

Путем перемасштабирования геометрических размеров и величины гидравлической проводимости в классической задаче двумерного потенциального течения через прямоугольную земляную перемычку с пустым нижним бьефом показано, ...
