Modelling water flow and seasonal soil moisture dynamics in an alluvial groundwater-fed wetland
Complex interactions occur in riparian wetlands between groundwater, surface water and climatic conditions. Knowledge of the hydrology of these systems is necessary to understand their functioning and their value and models are a useful and probably essential tool to capture their hydrological complexity. In this study, a 2D-model describing saturated-unsaturated water flow is applied to a tran...
متن کاملReconciling spatial and temporal soil moisture effects on afternoon rainfall
Soil moisture impacts on precipitation have been strongly debated. Recent observational evidence of afternoon rain falling preferentially over land parcels that are drier than the surrounding areas (negative spatial effect), contrasts with previous reports of a predominant positive temporal effect. However, whether spatial effects relating to soil moisture heterogeneity translate into similar t...
متن کاملSpace-time self-organization of mesoscale rainfall and soil moisture
The eects of mesoscale circulations induced by soil moisture heterogeneities are studied to assess the impact that the coupling of the land surface and the planetary boundary layer has on the rainfall and soil moisture dynamics at dierent scales. Our goal is to single out the most important physical mechanisms which aect the behaviour of the land-atmosphere system at the mesoscale leading to...
متن کاملA soil moisture–rainfall feedback mechanism 1. Theory and observations
This paper presents a hypothesis regarding the fundamental role of soil moisture conditions in land-atmosphere interactions. We propose that wet soil moisture conditions over any large region should be associated with relatively large boundary layer moist static energy, which favors the occurrence of more rainfall. Since soil moisture conditions themselves reflect past occurrence of rainfall, t...
متن کاملInvestigation of Rainfall-Runoff Processes and Soil Moisture Dynamics in Grassland Plots under Simulated Rainfall Conditions
The characteristics of rainfall-runoff are important aspects of hydrological processes. In this study, rainfall-runoff processes and soil moisture dynamics at different soil depths and slope positions of grassland with two different row spacings (5 cm and 10 cm, respectively, referred to as R5 and R10) were analyzed, by means of a solution of rainfall simulation experiments. Bare land was also ...
