Moreover, tendrils are also a sensitive indicator of vine water status: On nonstressed, vigorously growing shoots, the uppermost tendrils extend beyond the shoot tip. As water stress sets in and growth begins to slow, new tendrils remain small so that the shoot tip catches up with them. ...
The groundwater level has been continuously decreasing due to climate change and long-time overexploitation in the Xiong ’an New Area, North China, which caused the enhanced mixing of groundwater in different aquifers and significant changes in regional groundwater chemistry characteristics. In this ...
The criterion layer contains multiple indicators that can reflect the level of water ecological security. In order to comprehensively consider the impact of indicators on the level of water ecological security and fully obtain the new information brought by the indicator data, a multi-index weighted ...
Quantitative calculation methods mainly take the maximum population and economic indicators carried by water resources as the main targets, and design the utilization level of various resources and local economic development level, so as to analyze and calculate the size of water resources carrying ...
respectively, which are depleted in SO42−with respect to Cl−ions. Consequently, a Piper diagram shows that the water facies, in Djeffara aquifers, gradually changes from the Na–Ca–SO4–Cl type to the Na–Cl–SO4type along the flow lines, i.e., from west to east of the study ...
This is to be preferred over an absolute indicator that may substantially vary from one image to another, as the backscatter value depends on several factors, such as the incidence angle and the LoS. Thus, local Gi mitigates differences in the backscattering values of different classes due to ...
it is used as a mark of palatable attributes of drinking water and as an overall indicator of the chemical contaminants. Essential sources of TDS in aquifers include overflow from irrigated fields and private (or urban) spillover, effluent-rich mountain waters, filtering of soil sullying, and ...
This model utilized precipitation, evapotranspiration, and temperature as features and applied the Shapley value approach to analyze the influence of different features on the ground-water level prediction model [136]. The Shapley value allocation concept serves as a useful indicator for measuring the ...
