Optimization of regional water-quality- monitoring strategies Optimalisation des programmes régionaux de surveillance de la qualité des eaux
نویسنده
چکیده
The problem of optimizing a regional waterquality observation network is considered: the basic purpose of the network is to provide a statistically sound estimate of the annual nutrient load discharged into a lake by its tributaries. Following a brief description of the underlying lake eutrophication problem, first a single time period, single water quality component decision model is formulated, then several possible extensions are proposed. The methodology is illustrated by a numerical example.

Effects of climatic changes, progressing urbanization and improved environmental controls on the simulated urban stormwater quality in a Northern Sweden community were studied. Future scenarios accounting for those changes were developed and their effects simulated with the Storm Water Management Model (SWMM). It was observed that the simulated stormwater quality was highly sensitive to the sce...

Ecological constraints in subsurface environments relate directly to groundwater flow, hydraulic conductivity, interstitial biogeochemistry, pore size, and hydrological linkages to adjacent aquifers and surface ecosystems. Groundwater ecology has evolved from a science describing the unique subterranean biota to its current form emphasising multidisciplinary studies that integrate hydrogeology ...
