Nearly 24% of Formerly Used Defense Sites (FUDS) containing military munitions are in the nearshore coastal zone with approximately 30% of those sites containing heterogeneous sediment compositions of gravel-sand. Previous exploration in munition mobility was performed on beaches of sandy or muddy bottoms leaving the influence of heterogeneous sediment properties...
Sound wetland management depends on an accurate comprehensive
assessment of functional wetland values. This management should account
for the cumulative impacts to regions and landscapes resulting from
piecemeal destruction and degradation of wetland resources. A regional or
watershed evaluation of wetland values can also make site-specific
assessments more efficient. The...
