In addition, 18O and Deuterium undergo changes in the various phases of hydrologic environments, resulting in isotopic fractionation that gives isotopic "fingerprints" (Das et al. 1998).
The elements constituting the water molecule, hydrogen and oxygen, undergo changes in the various phases of hydrologic environments; atmosphere, hydrosphere, biosphere and the upper part of the earth's crust.
Thus monitoring NCP from space is very important to know how hydrologic environment affects the crop production.
Field runoff is an important transport mechanism by which pesticides move into the hydrologic environment of intensive agricultural regions such as California's Central Valley.
The combined effects of geophysical and ecological processes, such as water and sediment load, land use change, eustatic sea level rise, land subsidence, and wetland loss, have produced a dynamic eco-hydrologic environment of the Yellow River delta (YRD) in northern China.
The leachability and mobility of smelting and refining residuals constituents, including heavy metals and fluorides, and other potential toxicants in specific soil, geologic, and hydrologic disposal environments must be carefully considered in setting disposal requirements.
For preparation of tests in real sea, long-term investigations into status of ocean energy resources, hydrologic meteorological environment and seafloor sediments in test waters are needed.
Three study sites (Fig. 2) were selected based on diversified hydrologic and coastal environments, reflecting the distinct wave regimes prevailing at these localities.
This demonstrates the fairly different wave regimes, attributed to the different hydrologic and coastal environments which have been chosen for investigation.
The proper evaluation of evapotranspiration is essential in food security investigation, farm management, pollution detection, irrigation scheduling, nutrient flows, carbon balance as well as hydrologic modeling, especially in arid environments.
This study aimed to disclose impacts of environment changes on hydrologic regimes in the Hei River Watershed, Shaanxi Province in China.
