On the nature of persistence in dendrochronologic records with implications for hydrology
J.M. Landwehr, N.C. Matalas
1986, Journal of Hydrology (86) 239-277
Hydrologic processes are generally held to be persistent and not secularly independent. Impetus for this view was given by Hurst in his work which dealt with properties of the rescaled range of many types of long geophysical records, in particular dendrochronologic records, in addition to hydrologic records. Mandelbrot introduced an...

Delineating recharge areas for stratified-drift aquifers in Connecticut with geologic and topographic maps
E. H. Handman
1986, Water-Resources Investigations Report 83-4230
Stratified-drift aquifers, the major source of large quantities of groundwater in Connecticut, are recharged principally by (1) precipitation that infiltrates the land surface overlying the aquifer and percolates downward to the saturated zone, (2) subsurface inflow of groundwater from adjacent till-and-bedrock uplands, and (3) surface water that infiltrates through streambed...
