Terrain-Shape Indices for Modeling Soil Moisture Dynamics

Soil Moisture Measurement in Heterogeneous Terrain

Reliable soil moisture measurement over large areas is much needed for both hydrologic modelling and remote sensing applications. For collecting such data, portable electronic sensors offer a practical alternative to gravimetric measurements. The conversion of the measured electrical output to soil moisture is nonetheless a non-trivial task as it depends on soil type and temperature. In this st...

Estimating Soil Moisture Profile Dynamics from Near-surface Soil Moisture Measurements and Standard Meteorological Data

Gravitational and capillary soil moisture dynamics for distributed hydrologic models

Distributed and continuous catchment models are used to simulate water and energy balance and fluxes across varied topography and landscape. The landscape is discretized into computational plan elements at resolutions of 10–10 m, and soil moisture is the hydrologic state variable. At the local scale, the vertical soil moisture dynamics link hydrologic fluxes and provide continuity in time. In c...
