Summary: Agricultural drainage increases the connectivity between fields and receiving environments. This study investigated the hydrological functioning of a field combining surface and tile drainage. Quantifications of water partition between surface drainage, tile drainage, and soil water were conducted to understand the behavior of the field. The study also examined the contribution of macropores to tile drain runoff and proposed a conceptual model for surface and tile drainage hydrological functioning.

Summary: Water scarcity and soil salinization are major problems in arid irrigation districts with shallow groundwater table. A water and salt balance model was developed to study these issues, and it was successfully applied to the Hetao Irrigation District in China. The model revealed that evapotranspiration is the dominant water consumption component, and drainage through ditches plays a crucial role in salt balance. The study suggests the need for appropriate measures, such as decreasing irrigation water diversion and improving the drainage system, to address these problems and improve the sustainability of the irrigation district.

Summary: Rice production involves abundant water and fertilizer inputs and is prone to nitrogen loss, leading to agricultural diffuse pollution. Through experiments and modeling, the features and factors of nitrogen loss from paddy fields were analyzed, and optimizing nitrogen fertilizer inputs was suggested as a measure to control agricultural diffuse pollution.

Summary: Subsurface tile drainage (TD) is a common practice in improving crop production in poorly drained soils, but there is a lack of understanding about its regional impact on hydrology. This study incorporated a TD scheme into the National Water Model (NWM) and found that it improved the model's performance in heavily tile-drained areas. The TD scheme increased streamflow peaks, volume, and baseflow, while reducing surface runoff, groundwater recharge, evapotranspiration, and soil moisture content. These findings highlight the importance of considering TD in hydrological models.

Summary: DRINAMOD is a superior model used for assessing the impacts of agricultural drainage on farmland water balance. This study presents a novel artificial neural network model (ANNM) that mimics DRINAMOD but overcomes the limitation of fixed surface storage capacity. The developed ANNM shows excellent applicability in predicting water balance in artificial-drained farmlands, enhancing water resource assessment and agricultural productivity.

Summary: This study compared the soil water dynamics and rainwater productivity of different perennial grasses and legumes in eastern Australia. It found that a mixed sward of lucerne and digit grass was equally productive as fertilized digit grass, with lucerne dominating the herbage mass. Desmanthus and leucaena provided useful contributions in specific seasons and conditions, but underperformed overall compared to lucerne.

Summary: The representation of streams and drainage in 3D numerical catchment scale models significantly affects the estimated streamflow contribution. Despite similar hydraulic parameters and statistical performance, the estimated streamflow contribution differs between models, with the refined cell discretization model showing significantly higher drainage contribution to streamflow.

Summary: In this study, a novel water storage approach was used to estimate the field capacity (BFC) for different soil texture classes in southeastern Australia. Three new empirical equations were developed to estimate BFC based on SWAP-simulated drainage flux, the van Genuchten function parameter, and soil hydraulic conductivity or soil water content. The new equations were found to be better predictors of BFC than most of the published equations.

Summary: Soil nitrogen dynamics in rainfed agricultural production systems are influenced by the interaction of cover crops and rainfall. Integrating a winter wheat cover crop into a no-tillage corn-soybean rotation in northeastern Mississippi can reduce nitrate leaching and fertilizer nitrogen input.

Summary: This modeling study examines the effects of controlled drainage on hydrology and water quality in an agricultural field in Poland. The results show that controlled drainage can increase groundwater table, drainage outflow, and reduce nitrogen and phosphorus under future climate scenarios. Different climate models predict different outcomes.

Summary: Considering the interaction between surface and subsurface is crucial for predicting water movement and quality in the environment. In this study, a new efficient coupling routine for 1D surface-subsurface modeling was developed by combining KINEROS2 (K2) and HYDRUS-1D (H1D) open-source codes. The approach successfully accounted for surface ponding and water exchange between the two model domains, allowing for accurate representation of subsurface behavior below each overland flow plane.

Summary: The Chinese government plans to develop Xiong'an New Area to alleviate the population and service pressures in Beijing. Lake Baiyangdian, the largest freshwater wetland in the area, is expected to provide crucial ecosystem services. However, there is uncertainty whether the hydrological conditions of the lake can support this booming metropolis.

Summary: This study developed a monthly distributed agrohydrological model (DAHMID) based on remote sensing and groundwater depth measurements for studying agro-hydrological processes in arid irrigation districts. The results showed that interior drainage plays an important role in the climate processes of arid irrigation districts, and evapotranspiration is the major water consumption. Irrigation has a significant impact on soil water and groundwater depth.

Summary: This study analysed the spatio-temporal variability of soil water dynamics in dry areas, finding that soil water, percolation, and lateral flow increased with precipitation, while revap water showed a decreasing trend. The study also found no trend in SWC and percolation, with the contribution of revap water to ET varying with seasons.

Summary: The Zambezi River basin is vulnerable to climate change effects due to its highly variable climate. This study evaluates the impact of climate change on streamflow in the Kabombo basin using global climate models. Model predictions suggest an increase in streamflow under the RCP 8.5 scenario, indicating the need for adaptation and mitigation strategies, while a slight decrease in streamflow is predicted under the RCP 4.5 scenario, suggesting a potential need to review current water management strategies.

Summary: The optimal allocation of agricultural water and land resources is crucial for farmers' economic benefits, carbon sequestration, and water resource conservation. This study developed a novel water-carbon-economy coupling model and applied it to a real farm, demonstrating its effectiveness in achieving the optimal allocation of water and land resources. The model balances economic, environmental, and social benefits.
