-====== ​Simple models, motivation ​====== +====== ​Free Software ​====== 
-Hydrogeologists solving practical ​groundwater ​problems are facing significant uncertaintywhich is given by the lack of relevant data and the ambiguity of their interpretationMathematical models are used to understand the ongoing processes and to support decision-makingBecause of the uncertainty of the data and its interpretation it is appropriate to create multiple simple models – a “multiple model ensemble” (Uusitalo et al2015) – that can be later developed into more complex modelsEven simple models can help to select a strategy of further exploration ​and collection of data and to support preliminary decision-making+ 
-In this context simple ​models ​can be closed-form solutions ​and spatial analyses, which often make use of aggregated data and use simplified assumptions (e.g. geometry of the modelling domain is simplified to a single rectangle)Such models usually compute ​for example: balance ​(e.g. of water or chemicals), water flux (Darcy'​s law and continuity equation), flux of solutes or residence timeSlightly different are spatial computations performed mostly by geographical information systems ​(GIS– e.gthe pumping rate based on the distance from the fringe of the contaminant ​plumeAvailable screening modelling tools for contaminant transport ​(e.glength of steady-state contaminant plumecan be considered as simple ones tooTo support ​the formulation of conceptual models it is necessary to visualize ​and analyze data and to perform data aggregation and common calculation and estimations ​(e.gaverage hydraulic gradient, geochemical background or redox conditions from chemical composition). +==== Groundwater Modelling Tools ==== 
-The above issues mentioned require an information system that facilitates collection of data from various semi-structured sourcesvisualization ​and analysis ​of data in order to create alternative conceptual models and implement the corresponding simple procedural modelsInteroperability with third-party modelling software ​is also a requirement.+  * [[https://​water.usgs.gov/​software/​lists/​groundwater|USGS – Groundwater Software.]] Extremely useful: [[https://​water.usgs.gov/​nrp/​gwsoftware/​ModelMuse/​ModelMuse.html|ModelMuse]] –  GUI for [[https://​water.usgs.gov/​ogw/​modflow/​|MODFLOW]]MT3D-MS ​and other.
