This article will demonstrate the utility of a thermal-based remote sensing technique for monitoring evapotranspiration (ET), vegetation health/stress, and soil moisture status at local to continental scales. The paper is intended for researchers in a broad range of scientific disciplines – from the biosciences, atmospheric sciences, and hydrology – and also for policy makers in environmental a...

Integration of GIS and hydrologic models has been a common approach for monitoring our ever-changing hydrologic system. One important issue in adapting such an approach is to ensure the right correspondence of data across databases. To reach this goal, it is necessary to develop a description of the surface hydrology concepts that is internally consistent and semantically rich. In this paper, w...

Long-term trends of the combined effects of evapotranspiration and precipitation effect surface hydrology and soil water and consequently natural and agricultural ecosystems. This paper analyses yield index and soil water deficit time series derived from water balance calculations for multiple cropping systems with FAO methodology. The analysis shows that yield index values have increased and s...

1.1 Statement of problem Estimation of soil moisture using microwave remote sensors holds great promise for many applications, including numerical weather prediction and agriculture. However, a scale disparity exists between the resolutions of future satellite-borne microwave remote sensor data (30-60 km) and the much finer scales at which soil moisture estimates are desired (~ 1 km). Hydrology...

Hydrological processes and their spatial distribution directly are relevant to climate, topography, geology, and land use in the watershed. Therefore, use of a model whit integrity and high performance for simulating the process in deferent watersheds is very important. In this study was assessment performance of semi-distributed SWAT model in simulating hydrology processes in three watersheds ...

Soil-crop simulation models are widely used to assess the impacts of soil management and climate change on water balance, solute transport crop production. In this context, it is important that hydrological processes in soil-crop system accurately modelled. We suggest here empirical treatments flow, uptake by plant roots transpiration limit applicability increase prediction errors. further argu...
