Philippe Négrel mainly focuses on Geochemistry, Mineralogy, Dissolved load, Isotopes of strontium and Surface water. His study in the field of Massif is also linked to topics like Silicate. The various areas that Philippe Négrel examines in his Dissolved load study include Continental crust, Erosion and Tributary.
His work deals with themes such as Soil water and Weathering, which intersect with Isotopes of strontium. His work investigates the relationship between Surface water and topics such as Groundwater that intersect with problems in Wastewater. His Drainage basin research integrates issues from Sedimentary rock, Alluvium and Sediment.
Geochemistry, Groundwater, Hydrology, Weathering and Aquifer are his primary areas of study. His work carried out in the field of Geochemistry brings together such families of science as Structural basin, Isotopes of strontium, Carbonate and Mineralogy. His work deals with themes such as Environmental chemistry, Geothermal gradient and Trace element, which intersect with Mineralogy.
Many of his research projects under Groundwater are closely connected to Context with Context, tying the diverse disciplines of science together. His Weathering study also includes fields such as
His primary areas of investigation include Geochemistry, Weathering, Drainage basin, Hydrology and Groundwater. His primary area of study in Geochemistry is in the field of Sedimentary rock. His studies deal with areas such as Bedrock, Soil water, Sediment and Earth science as well as Weathering.
His research integrates issues of Watershed, Surface water, Effluent, Tributary and Surface runoff in his study of Drainage basin. In his work, Field campaign, Ebro delta, Seawater, Saltwater intrusion and Sedimentary organic matter is strongly intertwined with Mediterranean sea, which is a subfield of Hydrology. His work on Aquifer as part of general Groundwater study is frequently linked to Tracing, bridging the gap between disciplines.
His primary areas of study are Geochemistry, Weathering, Soil water, Aqua regia and Hydrology. He integrates Geochemistry with Crystallization temperature in his study. Philippe Négrel has researched Weathering in several fields, including Geochemical modeling and Trace element.
His Soil map and Soil test study, which is part of a larger body of work in Soil water, is frequently linked to Scale, bridging the gap between disciplines. His Hydrology research incorporates elements of Environmental chemistry and Smelting. Philippe Négrel combines subjects such as Schist, Sedimentary rock, Gneiss, Anorthosite and Archean with his study of Aquifer.
