On spatial adaptivity and interpolation when using the method of lines

چکیده
The solution of time-dependent partial diierential equations with discrete time static remesh-ing is considered within a method of lines framework. Numerical examples in one and two space dimensions are used to show that spatial interpolation error may have an important impact on the eeciency of integration. Analysis of a simple problem and of the time integration method is used to connrm the experimental results and a computational test for monitoring the impact of this error is derived and tested.

Evaluating optimized digital elevation precipitation model using IDW method (Case study: Jam & Riz Watershed of Assaloyeh, Iran)
A watershed management program is usually based on the results of watershed modeling. Accurate modeling results are decided by the appropriate parameters and input data. Precipitation is the most important input for watershed modeling. Precipitation characteristics usually exhibit significant spatial variation, even within small watersheds. Therefore, properly describing the spatial variation o...

In studies of irrigation and drainage projects for drainage, it is necessary to extend the data from the sampling point to the network. Therefore, based on available data from observational wells, estimating the state of hydraulic conductivity (K) in the surrounding area. The estimation process values for locations where there is no information for them based on viewing areas called wells spati...
متن کاملSpatial and Temporal Analysis of Dusty Days in Iran
Iran is one of the world's arid regions and exposed to dust particles in the air. This is important in spatial and temporal terms as well as the affects human health. In this paper a day when due to the amount of dust particles visibility reduces to 5,000 m is considered the dusty day. In the spatial and temporal analysis of dusty days 38 synoptic stations were studied. In order to conduct data...

متن کاملAccuracy Analysis of Precipitation Regionalization Methods Based on Spatial Interpolation Techniques in Zayandeh-Rud River Basin
In the present study, we used 27 precipitation average monthly data from synoptic, climatologic, rain-guage and evaporative stations located in Zayandeh-Rud river basin for the period of 1970-2014. Before interpolating, the missing data in the time series of each station was reconstructed by the normal ratio method. Also, for the data quality control, the Dickey-Fuller and Shapiro-Wilk tests we...
