② the water invasion patterns of gas reservoirs can be categorized into three types, these being explosive water flooding and channeling along faults, uniform intrusion along fractures, and combined intrusion along faults and fractures; ③ drawing from the characteristics of water invasion in various ...
For two combined ecoregions ("Mountains" and "Plains") we related objective measures of water clarity, including Secchi depth, turbidity, and water-column chlorophyll- a concentration to subjective visual assessments of recreational benefit quality. There were significant associations between water clarity...

He pointed out that the ecological dredging of the Taihu Lake can help increase the depth of the lake water, promote the circulation of the water body, effectively reduce the internal pollution of the lake body, and control the eutrophication of water bodies such as nitrogen and phosphorus. ...
An equation to predict the leaching of surface-applied nitrate The fraction (f) of surface-applied nitrate leached below any depthhcm in a uniform soil profile may be calculated from the equation wherePis the quantity of water draining through the soil (in cm) andVmis the percentage volumetric...
ratio of permeable to impermeable surface was less than 50%,the runoff coefficient would reach above 0.8.Increasing the depth of the permeability could increase runoff infiltration,and had significant reduction of surface runoff,but it had limited effect on reducing runoff from maximum 24-hour storm...
It has issued a special notice to the Guangdong provincial government requiring further implementation of flood control measures, including intensified monitoring, forecasting and early warning, and proper water storage and diversion. Guangdong was ...
