Soil conservation practices have been widely implemented on the Loess Plateau to reduce severe soil erosion in north-central China over the past three decades. However, the hydrologic impacts of these practices are not well documented and understood. The objective of this study was to examine how water yield has changed after implementing soil conservation practices that resulted in changes in ...
In the United States, clinical data management (CDM) has been accelerating from a single focus on collecting and preparing trial for study analysis to multi-pronged endeavor. This endeavor emphasizes quality inception or planning of design collection, coding, analysis, reporting, sharing all applicable available data. this article influence legislation scientific expertise in collection valid, ...
The trend of river discharge changes in arid and semi-arid regions is mostly decreasing and this trend can be influenced by climatic factors and rising temperatures in recent decades in these areas. This reduction in discharge could have a significant impact on the water storage of the Nahrin Dam and agriculture, industry and drinking water in Tabas City, which should be considered by experts. ...
The comparison of modern hydrophysical conditions in the Black Sea with previously analyzed period 1903—1982 was carried out based on materials recently created (1991—2020) climate array average monthly thermohaline characteristics waters. dynamic processes upper 150-meter layer (halocline) evaluated analysis climatic vertical distribution depth maximum water salinity gradient, which is interpr...
abstract the aim of the present study is to explore the impact of the cognitive reading strategy instruction on learners reading self-efficacy and their reading achievement. in order to fulfill this purpose, from 120 participants, 90 intermediate efl learners as an experimental group were chosen from three different educational settings namely, yazd university, yazd science and art un...
Sensitivity analysis to determine variations in evapotranspiration is much important considering a known variation in one of climatic variables. In this study, sensitivity of evapotranspiration from Penmann-Mantith, Penmann-Kimberly (1996), Penman-Kimberly (1972) and Penmann (1984) and Hargrivs (1985) approaches to three climatic variations (maximum temperature, wind speed, solar radiation) wa...

Deserts are important landscapes on the earth and their variations have impacts global climate through feedback processes. However, there is a limited understanding of climatic controls spatial temporal deserts. Here, we use reanalysis datasets, land use/land cover (LULC) products CMIP6 (Coupled Model Intercomparison Project) model outputs to calculate changing deserts during 1982–2020, estimat...
As pointed out in the introduction to this book, shales contain the lion’s share of earth history that is recorded in sedimentary rocks. Understanding their deposition is key to the reconstruction of past oceans, landscapes, climates, and climatic cycles. Yet, whereas students of sandstones and carbonates have been able to learn a great deal about the deposition of these rocks from studying bed...
