Regional precipitation analysis with Python

March 20, 2017/ Saul Montoya

We want to analyze average annual precipitation data on a regional scale for the North of Peru. The dataset has 20 stations from the Peruvian desert coast, Andes and rainforest with differences in elevation and precipitation rates.

The main objective is to analyze precipitation patterns and trends by plotting them in different ways using Python.

For this task we use IPython Notebook, which you can install on your own computer or run it on the cloud from wakari.io. You can download the station data for this exercise here

Questions on MODFLOW with Model Muse

March 20, 2017/ Saul Montoya

Some questions from a follower:

Thanks for agreeing to help. I developed a simple mode just to check if it works. But I get this error (attached). There are NO streams in my study area so do I still need to give my model a input for drainage package? I wanted to go around it but I could not proceed, therefore I created streams as drainage lines from DEM.

Why consultants, mines and organizations should migrate to QGIS?

March 17, 2017/ Saul Montoya

This question has been popular for the last three or four years. I have been using Quantum GIS (QGIS) from version 0.8, and now QGIS is on version 2.4.

Statistical analysis of precipitation data with Python 3 - Tutorial

March 17, 2017/ Saul Montoya

This tutorial is intended to be a basic reference in Python programming for water resources professionals. The script covers many steps on the data management, representation and analysis with the most common Python commands and libraries. It is encouraged to review first all the described steps with the provided input data and then apply to the user own hydrological data. The same analysis will be ported to Julia on future tutorials to have a overview of the similarities / differences between programming in Python or Julia for hydrological data.

Assessment of land subsidence from pumping

March 17, 2017/ Saul Montoya

The MODFLOW SUB-WT code has been developed to simulate vertical compaction in regional groundwater flow models due to pumping.

MODFLOW SUB-WT can simulate changes in groundwater storages and compaction in discontinuous layers or extensive confining units. The MODFLOW SUB-WT modeling code considers the compaction of a particular layer of the numerical model as a function of effective effort changes in the layer.

How much does a groundwater modeler cost?

March 17, 2017/ Saul Montoya

After my last job as a staff groundwater modeler, I have received 6 unsolicited job offers. Of course many modelers with more years and more conections than I, have received much more offers, however, I feel happy with my humble record. The point of this comparison is that senior groundwater modelers with experience in mining hydrogeology are really scarce. Mining and consultant companies are looking for talented groundwater modelers, and somehow there are not much modelers coming out from the universities.
