Summary
The response of plants to drought has received significant attention, but far less attention has been given to the dynamic response of plants during recovery from drought. Photosynthetic performance and hydraulic capacity were monitored in seedlings of Hevea brasiliensis under water…

Theri lands are located along the coastal areas of Tuticorin district of Tamilnadu, South India. Proper management of the land is difficult because of its poor quality structure, low nutrition, meagre moisture holding capacity, low value of organic content, and high value of hydraulic conductivity. The permeability of water in theri soil is high and is not suitable for agriculture which is presently considered as a wasteland. The objective is to nurse the soil back to health and reclaim the soil. Goat Manure amended with theri soil characteristics are studied separately. In this amendment, ten different combinations are tried. Using this organic amendment the soil Physical, Physico-Chemical and Chemical properties are studied which makes the soil cultivable and to arrive at their interrelationships in reclaiming the soil. A field experiment is conducted at PunnaiNagar (Kachanavillai) that is located at 19 km west from Tiruchendur of Tuticorin district, Tamilnadu. This study tests for the changes of physical properties through the addition of goat manures and aims in describing relationship among the soil physical properties such as bulk density(BD),Particle density(PD),Water holding density(WHC), Pore space (PS),Hydraulic conductivity(HC),Thermal Conductivity(TC), Volume Expansion(VE) of the soil through various methods. Physico-Chemical properties like Electrical conductivity (EC), Potential of Hydrogen (pH) and Chemical properties namely NPK, Organic Carbon (OC) are also studied.
Abstract We present equations for new limitless analytic line-elements. These elements possess a virtually unlimited number of degrees of freedom. We apply these new limitless analytic elements to head-specified boundaries and to problems with inhomo https://www.environmentguru.com/pages/elements/element.aspx?utm_source=dlvr.it&utm_medium=tumblr&id=6061659
Petrophysical, Geochemical, and Hydrological Evidence for Extensive Fracture-Mediated Fluid and Heat Transport in the Alpine Fault s Hanging-Wall Damage Zone
Abstract Fault rock assemblages reflect interaction between deformation, stress, temperature, fluid, and chemical regimes on distinct spatial and temporal scales at various positions in the crust. Here we interpret measurements made in the hanging-wa https://www.environmentguru.com/pages/elements/element.aspx?utm_source=dlvr.it&utm_medium=tumblr&id=6059711
Physical Controls on Biogeochemical Processes in Intertidal Zones of Beach Aquifers
Abstract Marine ecosystems are sensitive to inputs of chemicals from submarine groundwater discharge. Tidally influenced saltwater-freshwater mixing zones in beach aquifers can host biogeochemical transformations that modify chemical loads prior to d https://www.environmentguru.com/pages/elements/element.aspx?utm_source=dlvr.it&utm_medium=tumblr&id=5997249

On the Longitudinal Dispersion in Conservative Transport Through Heterogeneous Porous Formations at Finite Peclet Numbers
We consider transport of a conservative solute through an aquifer as determined: (i) by the advective velocity, which depends upon the hydraulic conductivity K and (ii) by the local spreading due to the pore-scale dispersion (PSD). The flow is steady https://www.environmentguru.com/pages/elements/element.aspx?utm_source=dlvr.it&utm_medium=tumblr&id=5807497
Minimum Hydraulic Resistance and Least Resistance Path in Heterogeneous Porous Media
Abstract The transport dynamics of a solute plume in porous media are strictly related to the hydrogeological properties. Despite progress in simulation techniques, quantifying transport in strongly heterogeneous geological formations is still a chal https://www.environmentguru.com/pages/elements/element.aspx?utm_source=dlvr.it&utm_medium=tumblr&id=5767111
