ABSTRACT Wet deposition significantly impacts the basin ecosystem and water quality of Qinling Mountains (QMs). However, few research focused on difference in wet between northern (QN) southern (QS) foothills due to barrier effect QMs. This two-year investigation studied nutrient organic matter QN QS during summer autumn.

Forest water dynamics and hydro-chemical characteristics are essential for understanding forest hydrology ecological processes. Yet, such is limited by a lack of long-term monitoring data observations from specialized ecosystems as those high elevation. Here, we analyze the precipitation redistribution including interception, stemflow, throughfall using 15 year (2005–2019) dataset in elevation, evergreen broad-leaved Southwest China. The experienced an obvious seasonal variation with monthly average 117.31 ± 91.21 mm. was influenced intensity leaf area index differed inter-annually intra-annually, general pattern: > canopy interception stemflow. Throughfall rate increased significantly 2015 to 2019 after experiencing January snowstorm. majority within study site retained soil apoplastic materials. primary means output evapotranspiration, minimal surface runoff. Quality affected weathering rocks, resulting lower pH than that atmospheric precipitation. During rainy season, elemental Ca Mg showed negative correlation due plant mediation. other elements, pH, total dissolved solids, precipitation, air temperature, temperature different degrees each other. Overall, while balance fluctuated over past years, water-holding capacity remained relatively stable. Alkali cations Ca2+, Mg2+, K+ body decreasing trend during 2005–2019, which potential threat stability.

Acid rain is linked to the process of urbanization and industrialization harms buildings. This study aims evaluateacid in Kirkuk city using GIS-based spatial analysis, mathematical statistical modeling, laboratory tests andexamine harmful effects on buildings human health. Precipitation ranges were determined based onTheisen’s polygon techniques. The methodology two types measurements specific rainfallsamples within for period January 2021 March 2022. Geographical Information Systems GISs wereused verify distribution quantity precipitation data area. Remote sensing RS was alsoused mapping rainfall rates during period. According maps, acidity level rainwas classified as (least acidic) ranging between (5.5 5.6). Specifically southern south-eastern parts thestudy Besides, distributions have been presented with high accuracy 95% 83% ratings in2021 2022, respectively. Thus, we attempt offer some useful guidelines conserving so that they arepreserved a long time. GIS techniques are best suited estimating modeling datacharacteristics.
