Blocking Moving Window algorithm: Conditioning multiple-point simulations to hydrogeological data

Alcolea, Andres ; Renard, Philippe

In: Water Resources Reserach, 2010, vol. 46, no. W08511, p. 1-18

Connectivity constraints and measurements of state variables contain valuable information on aquifer architecture. Multiple-point (MP) geostatistics allow one to simulate aquifer architectures, presenting a predefined degree of global connectivity. In this context, connectivity data are often disregarded. The conditioning to state variables is usually carried out by minimizing a suitable...

Reducing the impact of a desalination plant using stochastic modeling and optimization techniques

Alcolea, Andres ; Renard, Philippe ; Mariethoz, Gregoire ; Bertone, François

In: Journal of Hydrology, 2009, vol. 365, no. 3-4, p. 275-288

Water is critical for economic growth in coastal areas. In this context, desalination has become an increasingly important technology over the last five decades. It often has environmental side effects, especially when the input water is pumped directly from the sea via intake pipelines. However, it is generally more efficient and cheaper to desalt brackish groundwater from beach wells rather...
