Estimating uncertainties in watershed studies

Estimating Uncertainties for Geophysical Tomography

We present statistical and interval techniques for evaluating the uncertainties associated with geophysical tomographic inversion problems, including estimation of data errors, model errors, and total solution uncertainties. These techniques are applied to the inversion of traveltime data collected in a cross well seismic experiment. The inversion method uses the conjugate gradient technique, i...

Estimating the Available Water in the Watershed using System Dynamics Hydrological Model (Case Study: Ilam Watershed)

Hydrological models provide water managers with the available amount of water in the watershed. In this paper, we firstly developed a system dynamics model to calculate the available amount of water in the watershed. Then, we defined two scenarios one of which is the development scenario describing how land use changes can affect water availability in the watershed. Next, we divided the watersh...

Estimating Watershed-Scale Precipitation by Combining Gauge

4 Watershed modeling requires accurate estimates of precipitation, however in some cases 5 it is necessary to simulate streamflow in a watershed for which there is no precipitation gauge 6 records within close proximity to the watershed. For such cases, we propose an approach for 7 estimating watershed-scale precipitation by combining (or fusing) gauge-based precipitation 8 time series with rad...
