Land use is one of the key factors affecting soil erosion in Loess Plateau China. This paper examines under different land uses and land-use combinations using 137 Cs tracing Yangjuangou Catchment, a tributary Yan River Northern Shaanxi Province. The results show that order activity decreases sequentially from mature forest to grass young orchard terrace crop, indicating forests had lowest rates while terraced cropland produced highest amount. majority distributed top 0—10 cm layer....
Abstract. Check dams are commonly used for soil conservation. In the Loess Plateau of China, check have been widely constructed as principal means to retain floodwater and intercept sediments since 1970s. For instance, there more than 6572 in Yanhe watershed with an area 7725 km2 Plateau. However, little research has done quantify hydrological effects dams. this research, SWAT model (Soil Water Assessment Tool) was applied simulate runoff sediment watershed. We treated 1950s 1960s reference...
As the world's top two economies, United States (U.S.) and China face a number of similar water resources problems. Yet, few studies have been done to systematically compare policies approaches on management between U.S. This study compares in areas national authority, supply, quality, ecosystem use draw lessons learned shed light China, U.S., rest world. The from comparison include six aspects. 1) New paradigms people-water harmony water-saving society are urgently needed address pressing...
Abstract Since 1999, the Loess Plateau, China, has undergone one of world's largest revegetation programs (Grain for Green Project, GfGP). Revegetation profound impacts on hydrological cycle and water balance, especially in arid semi‐arid areas. As an essential component long‐term change storage ( ΔS ) is generally treated as zero. However, it remains unclear how to define time scale “long‐term,” over regions undergoing dramatic vegetation restoration. In this study, we quantify Plateau from...
The glacierized Tien Shan - Pamir Karakoram mountain complex supplies water to about 42 million people. Yet, the knowledge future glacial runoff in response climate is limited. Here, we address this issue using a hydrological model, that includes three components of runoff: ice melt, snowmelt and rainfall over ice. model forced by projections CMIP5 models. We find exhibit different long-term trajectories, sometimes opposite sign trend glacier impacts. For eastern slope basins, streamflow...
Abstract Large‐scale vegetation restoration profoundly affects ecohydrological and hydrometeorological processes with consequent effects on soil water conservation. However, it is still unclear how revegetation the joint relationship between streamflow sediment yield from land‐atmosphere interactions perspective. In this study, we combine in situ hydro‐meteorological observations, satellite observed land surface characteristics, coupled model simulations to address knowledge gap through a...
Abstract Understanding the variability in soil hydraulic conductivity mountainous headwaters is critical to modeling of runoff and water resources management river basins, especially arid semiarid areas. In this study, a total 32 profiles with five layers within 0–70 cm were sampled under different land cover types: forest, meadow, high coverage grassland (HCG), medium (MCG), barren upper stream Heihe watershed, Northwest China. Saturated ( K S ) was measured for each sample. The vertical...
Abstract Spatial heterogeneity of soil has great impacts on dynamic processes the hydrological systems. However, it is challenging and expensive to obtain spatial distribution hydraulic properties, which often requires extensive sampling observations intensive laboratory analyses, especially in high elevation, hard access mountainous areas. This study evaluates process a topographically complex watershed Northwest China. Two approaches were used derive properties watershed: (1) clustering...
Abstract Land use and land cover change (LUCC) can influence the regional atmospheric water budget. In this study, Weather Research Forecasting model embedded with evapotranspiration (ET)‐tagging (WRF‐tagging) is used to investigate pathways of ET as well where what extent returns precipitation (P) in agro‐pastoral ecotone northern China (APENC). First, we updated default vegetation indices WRF‐tagging high‐resolution real‐time datasets. modeling reproduces spatial distribution P reasonably...
The complexity of the spatial distribution and temporal occurrence preferential flow (PF) makes it challenging to understand mechanisms PF. This study aims identify patterns PF using machine learning (Classification Regression Trees Random Forests) in Qilian Mountains, Northwest China. Our results show that detected events transport much more rainfall down subsoil than non-PF events. Different vegetation types exhibit variations main soil layers where occurs, which is closely related roots....
Understanding the mechanisms governing infiltration of precipitation into soil is crucial in eco-hydrological processes. However, effect vegetation types on wetting front depth and velocity poorly understood. Here, we analyzed 1234 events based a large-scale long-term in-situ moisture monitoring network arid mountainous area northwest China. Our results show that proportion preferential flow was largest shrub (52.38%), followed by alpine meadow (36.55%), grassland (11.51%), barren (0.70%)....
Abstract Runoff in the Amu Darya River (ADR) central Asia has been declining steadily since 1950s. The reasons for this decline are ambiguous, requiring a complete analysis of glaciohydrological processes across entire data-scarce source region. In study, grid databases precipitation from Asian Precipitation–Highly Resolved Observational Data Integration Toward Evaluation Water Resources (APHRODITE) and temperature Princeton’s Global Meteorological Forcing Dataset (PGMFD) used to force...
