TREE ROOT ENCROACHMENT ON LEVEE DRAINAGE SYSTEM
… drainage material. For the last study element, HYDRUS-2D was applied to understand the soil water movement in the levee. The typical toe drain and the geocomposite edge drain were considered, and the models were run under the ambient condition (unsaturated) and the flood condition (saturated). …

Quantifying the contribution of bank storage due to an alteration in stream stage
… inputs for a two-dimensonal groundwater model (HYDRUS-2D), which was used to quantify bank storage under a variety of scenarios. Multiple scenarios were studied to answer the research questions; these included variations in the flood stage, flood duration, and variations to the alluvial …

Budget and fluxes of nitrogen in mountainous agroecosystems in a summer monsoonal climate under intensive land use
… using 15N tracer. N leaching was simulated with Hydrus 2D. The comparison of 4 N fertilization levels (0, 150, 250 and 350 kg N ha-1) revealed that already 150 kg N ha-1 is sufficient to reach the maximal yield of radishes. Based on the low results of fertilizer N use efficiency (FNUE), we …

Impacto de la zona no saturada en el transporte de metales pesados y compuestos de nitrógeno (amonio, nitritos, y nitratos), en el área industrial de Bahía Blanca
… de agua. La calibración de un modelo numérico (HYDRUS 2D/3D) permitió representar correctamente el comportamiento hidrodinámico de la ZNS. Se cuantificó la retención de cadmio (Cd) en tres niveles del subsuelo de la parcela experimental. La afinidad del Cd por los niveles analizados fue en el …

Analysis and management of low flows in small catchments of Brandenburg, Germany
… irrigated area were evaluated using the model Hydrus-2D. Increasing antecedent water levels and stopping ditch irrigation during periods of low flows increased fluxes from the pasture to the stream, but storage was depleted faster during the summer months due to higher evapotranspiration. …

Evaluation of Modern Irrigation Techniques with Brackish Water
Modern irrigation techniques are becoming increasingly important in water-scarce countries especially in arid and semiarid regions. Higher crop production and better water use efficiency are usually achieved by drip irrigation as compared to other irrigation methods. Furthermore, by using drip …
