Current Research

Professor Mariño's research encompasses hydrological systems. The majority of his recent research has centered on either irrigation or subsurface hydrology, and typically involves mathematical modeling utilizing optimization procedures.

Optimization and simulation models are being developed and tested for planning the management of irrigation districts that use surface and ground water to irrigate crops. The models will give the cropping pattern and the monthly schedule for reservoir releases and aquifer withdrawals that maximize the annual profit in the district.

The optimal design and operation of water distribution systems is being studied using genetic algorithm optimization to automatically determine annually the least cost of pumping stations while satisfying target hydraulic performance requirements. Optimal design and operation refers to the selection of pump type, capacity, and number of units as well as scheduling the operation of irrigation pumps that result in minimum design and operating cost for a given set of demand curves.

Hybrid analytical-numerical methods are being developed and tested for three-phase (dissolved, adsorbed, and vapor phases) pesticide transport modeling in the vadose zone and under conditions of heterogeneous porous media, unsteady flow fields, and space-time-dependent physical and biochemical processes concerning pesticide environmental fate. Also taken into account is pesticide runoff and erosion and pesticide transport in the plant canopy zone.
