Interim report on the hydrologic features of the Green Swamp area in Central Florida [PDF]

open access: yes, 1961
The Green Swamp area in central Florida is another area where man is developing agricultural land from marginal land. Though the area is by no means as extensive as that of the Everglades, the present efforts for its development are similar to the ...

Carbonate Aquifers

open access: yes, 2012
Only limited hydrogeological research has been conducted using ichnology in carbonate aquifer characterization. Regardless, important applications of ichnology to carbonate aquifer characterization include its use to distinguish and delineate depositional cycles, correlate mappable biogenically altered surfaces, identify zones of preferential ...

Models for wellhead protection in regional unconfined aquifers and stratified aquifers

open access: yesGeofísica Internacional, 2004
En este trabajo son presentados los conceptos matemáticos usados para el desarrollo de la protección de cabezales de pozos y la metodología de zonificación. Ellos están basados en soluciones analíticas, en el flujo del agua subterránea y en la modelación en diferencias finitas del rastreo de partículas.

Remote sensing of soil organic carbon in varied tillage‐crop systems

open access: yesJournal of Environmental Quality, EarlyView.
Abstract The use of remote sensing (RS) to estimate soil organic carbon (SOC) in cropland has become increasingly important to producers, researchers, and policy makers to assess soil and plant health across spatially variable landscapes. Yet, RS estimation of cropland SOC is challenging, particularly when mixed crop residues and soils are present. Our

Ground-water resources of the lower Hillsboro Canal area, Southeastern Florida [PDF]

open access: yes, 1970
This study was done to determine the amount and kinds of water being produced from the lower Hillsboro Canal Area in Palm Beach and Broward counties. All of the potable ground water being produced from the Biscayne aquifer is developed from the canal

Microplastics Identification in Remote Aquatic Environments Using Raman Spectroscopy: A Case Study for Mt. Tymfi's Alpine Lake

open access: yesJournal of Raman Spectroscopy, EarlyView.
This work contributes to the literature on the detection of MPs in Greece, proposes a method for MPs extraction in remote environments taking into account fieldwork constraints of an expedition in the Greek Alps, and takes a step forward in MPs analysis by Raman spectroscopy. ABSTRACT Water samples from the alpine lake of Mt.
