additional information of model groundwater flow and nitrate transport (FLOW2d)
period of development:
from 01.01.1991 to 01.01.1993
aim of model:
name of area: District of Vechta (Area of waterworks Holdorf)
elevation above sealevel: 34 m (City of Vechta)
upper left corner: 8 0'E; 52 36'N
lower right corner: 8 10'E; 52 30'N
stepsize from: 5.000 to: , unit: days
time frame from: 1.000 to: 100.000, unit: years
state of development:
The model is fully calibrated and validated both in ground-water level and nitrate concentration for the area of the waterworks of Holdorf.
further remarks concerning the state of development:
The used techniques are well known and generally accepted to be adequate for modeling ground-water flow. The simulation of contaminant mass flux is sufficiently accurate and the model can thus be regarded as completely developped.
limitations of use:
As long as Darcy' s law is valid (i.e. laminar flow is regarded), the model can be used to simulate ground-water flow and contaminant transport.
number of users worldwide: 5
number of users nationwide: 0
current use: number of users worldwide is unknown.
uses aimed at: research, engineering, planning
suggested measures for transfer in other areas:
Every kind of flow and transport of ideal tracers in a two-dimensional domain can be modeled as long as the processes are obeying the same laws as here and parameters are known.
use of the model:
support required: No support required.
support available: The author is willing to answer any question.
interactive use posible: No.
