subsurface drainage systems are used to control the depth of the water table and to reduce or prevent soil salinity. water flow in these systems is described by the boussinesq equation, and the advection-dispersion equation coupled with the boussinesq equation is used to study the solute transport. the objective of this study was to propose a finite difference solution of the advection-dispersi...

The world has a long experience of using harvested rainwater from rooftop catchments in urbanized regions. There are also many studies about the technical, health, and environmental details of such systems. The gradual prevalence of rainwater harvesting systems in the country exposes a necessity to determine and define some guidelines and instructions for health and environmental considerations...

Macroalgae is a biological key element for the assessment of the ecological status in coastal waters in the frame of the European Water Framework Directive (WFD, 2000/60/EC). Here we propose a methodology for monitoring water quality based on the cartography of littoral and upper-sublittoral rocky-shore communities (CARLIT, in short). With the use of spatial databases, GIS, and available inform...
