Abstract The magnitude of sediment yield following forest timber harvest is controlled by increases in both sediment supply and streamflow. Since the relation between sediment transport and streamflow typically follows a power law, small increases in streamflow may translate into large increases in sediment transport. Interpreting the geomorphic effects of streamflow increases is confounded by the fact that timber harvest influences both the hydrologic regime and sediment supply of a watershed s...

Abstract Infiltration processes in layered slopes can be strongly affected by the different hydraulic properties of the soils constituting the layers, with potential downslope flow diversion that can have effects on slope stability as well as on runoff generation and groundwater recharge. In this respect, volcanoclastic soil covers represent a typical example, as layers with strongly contrasting textures are deposited during the various eruptive phases. In this paper, the results of a transient ...

Abstract A better understanding of responses of the regional water-energy cycle to land use/cover change (LUCC) is important for ecological restoration in the agro-pastoral ecotone, Northwest China (APENWC). In this study, we examined the responses to various types of LUCC in the APENWC during the implementation of the Grain-for-Green project between 1993 and 2010 using the weather research and forecasting (WRF) model. The performance of the WRF model was validated by multiple types of observati...

Abstract To date, many laboratory-based core scale (i.e. flooding) studies have focused on relatively homogeneous rock samples (e.g. Berea sandstone) to study the migration characteristics of supercritical carbon dioxide (SC-CO2) and evaluate these rocks for their potential geological CO2 storage as an option for mitigating global warming caused by greenhouse gas emissions. Clay interlayers with low porosity and permeability within a sandstone are often encountered in target reservoirs and can h...

Abstract A new control volume approach is developed based on compact integrated radial basis function (CIRBF) stencils for solution of the highly nonlinear Richards equation describing transient water flow in variably saturated soils. Unlike the conventional control volume method, which is regarded as second-order accurate, the proposed approach has high-order accuracy owing to the use of a compact integrated radial basis function approximation that enables improved flux predictions. The method ...
Abstract Understanding the nature of water conflicts is a prerequisite to developing sustainable management of common water resources. Therefore, the main idea of this research was to understand the internal process of farmers’ water conflicts. An extended theory of planned behavior (TPB) was used as the theoretical research framework by incorporating multiple intentions (an expectation of conflict with industry, organization, and farmer) and four conflict types: within group in similar settleme...
Abstract Knowing the location where groundwater denitrification occurs, or by proxy the groundwater redox status (oxic, mixed, and anoxic), is valuable information for assessing and managing potential agricultural land-use impacts on freshwater quality. We compare the efficacy of supervised (Linear Discriminant Analysis LDA; Boosted Regression Trees, BRT; and Random Forest, RF) and unsupervised (Modified Self-Organizing Map, MSOM) learning-based methods to predict groundwater redox status in the...

Abstract To investigate the dynamics of phosphorus fractions and their influencing factors in the surface soils of estuarine wetlands experiencing different hydrological conditions before and after flow-sediment regulation, soil samples were collected in wetlands (tidal flooding wetlands (TFW), freshwater restoration wetlands (FRW) and freshwater flooding wetlands (FFW) of the Yellow River Estuary in each month from April to October of 2012. Our results showed that the average contents of organi...

Abstract Droughts in India affect food production, gross domestic product (GDP), livelihood, and socio-economic condition of a large population associated with agriculture. Recent drought (2015-2018) caused groundwater depletion and affected about one-fourth of the Indian population. However, it remains unclear if the drought of 2015-2018 was among the most severe droughts that occurred in India. Here we use a long-term (1870-2018) data to identify the top five (“deadly”) meteorological/hydrolog...

Abstract CO2 breakthrough pressure plays an important role in the capacity, safety and caprock evaluation of CO2 geo-sequestration. Many laboratory experiments have been put forward to investigate the breakthrough pressure and some functional relationships are proposed. Meanwhile, some numerical simulation theories on two-phase flow have also been presented by scholars. However, up to now, no numerical simulation method for CO2 breakthrough pressure has been put forward. In this study, a numeric...
